PROSPECTUS

CNS PHARMACEUTICALS, INC.

Up to 9,793,479 Shares of Common Stock

This prospectus relates
to the resale, from time to time, by the selling shareholders (the “ Selling Shareholders ”) identified in this prospectus
under the caption “Selling Shareholders,” of up to 9,793,479 shares of our common stock. The 9,793,479 shares of common
stock offered for resale hereby consist of (i) 650,000 shares of our common stock purchased by the Selling Shareholders, and (ii)
9,143,479 shares of common stock issuable upon exercise of pre-funded common stock purchase warrants (the “Pre-Funded
Warrants”) purchased by the Selling Shareholders. Subject to certain ownership limitations, the Pre-Funded Warrants are
exercisable immediately for one share of common stock at an exercise price of $0.001 per share and have no expiration date,
remaining exercisable until exercised in full. See “ Prospectus Summary – May Private Placement ” for additional
information regarding the private placement transaction pursuant to which the shares of common stock and Pre-Funded Warrants were
acquired.

We are registering the resale
of the shares of common stock and the shares of common stock issuable upon exercise of the Pre-Funded Warrants on behalf of the Selling
Shareholders, to be offered and sold by the Selling Shareholders from time to time.

We are not selling any shares
of common stock under this prospectus and will not receive any proceeds from the sale by the Selling Shareholders of such shares. We are
paying the cost of registering the shares of common stock covered by this prospectus as well as various related expenses. Each Selling
Shareholder is responsible for all selling commissions, transfer taxes and other costs related to the offer and sale of its shares.

Our common stock is listed
on The Nasdaq Capital Market (“Nasdaq”) under the symbol “CNSP.” On May 18, 2026, the closing price of the common
stock, as reported on Nasdaq, was $4.71 per share. There is no established public trading market for the Pre-Funded Warrants, and we do
not expect a market to develop. In addition, we do not intend to apply for a listing of the Pre-Funded Warrants on any national securities
exchange.

You should read this prospectus,
together with additional information described under the headings “ Incorporation of Certain Information by Reference ”
and “ Where You Can Find More Information , ” carefully before you invest in any of our securities.

Investing in our securities
involves a high degree of risk. See the section entitled ” Risk Factors ” beginning on page 5 of this
prospectus for a discussion of risks that should be considered in connection with an investment in our securities.

Neither the Securities
and Exchange Commission nor any other regulatory body has approved or disapproved of these securities or passed upon the accuracy or adequacy
of this prospectus. Any representation to the contrary is a criminal offense.

ABOUT THIS PROSPECTUS

This prospectus is part of
the registration statement that we filed with the Securities and Exchange Commission (the “SEC”) pursuant to which the Selling
Shareholders named herein may, from time to time, offer and sell or otherwise dispose of the shares of our common stock covered by this

We further note that the representations,
warranties and covenants made by us in any agreement that is filed as an exhibit to any document that is incorporated by reference in

and research, surveys and studies conducted by third parties. Management estimates are derived from publicly available information, our
knowledge of our industry and assumptions based on such information and knowledge, which we believe to be reasonable. In addition, assumptions
and estimates of our and our industry’s future performance are necessarily uncertain due to a variety of factors, including those

performance to differ materially from our assumptions and estimates.

to the registration statement of which this prospectus is a part. All references in this prospectus to “ we, ” “ us, ” “ our, ”
“CNS,” “ CNSP, ” the ” Company ” and similar designations refer to CNS
Pharmaceuticals, Inc., unless otherwise indicated or as the context otherwise requires.

All trademarks or trade
names referred to in this prospectus are the property of their respective owners. Solely for convenience, the trademarks and trade names
in this prospectus are referred to without the ® and ™ symbols, but such references should not be construed as

Our Company

We are a biotechnology company
organized as a Nevada corporation in July 2017. In March 2026, we announced a new corporate strategy focused on developing innovative
therapies for serious diseases. We are leveraging our executive team’s multi-functional experiences across high-value therapeutic
areas to execute our new corporate strategy, which also includes pivoting from a singular focus on glioblastoma multiforme and exploring
out-licensing opportunities for our legacy assets TPI 287 and Berubicin for which we have intellectual property rights under license agreement
with Cortice Biosciences, Inc. and own pursuant to a collaboration and asset purchase agreement with Reata Pharmaceuticals.

Recent Developments - May Private Placement

On May 4, 2026, we entered
into a Securities Purchase Agreement (the “Purchase Agreement”) with the Selling Shareholders for the private placement of
(i) 650,000 shares of our common stock at $2.30 per share, and (ii) Pre-Funded Warrants to purchase 9,143,479 shares of common stock at
a purchase price of $2.299 per Pre-Funded Warrant (the “Private Placement”).

Subject to certain ownership
limitations, the Pre-Funded Warrants are exercisable immediately at an exercise price of $0.001 per share (subject to adjustment) and
remain exercisable until exercised in full. A holder may not exercise any Pre-Funded Warrant to the extent that, after giving effect to
such exercise, the holder and its affiliates would beneficially own more than 4.99% (or 9.99%, as applicable) of the total number of shares
of our common stock outstanding immediately after giving effect to the exercise, which percentage may be increased or decreased at the
holder’s election not to exceed 9.99%.

The closing of the Private
Placement occurred on May 5, 2026 (the “Closing Date”). We received gross proceeds of approximately $22.5 million, before
deducting placement agent fees and other offering expenses, and intend to use the net proceeds to identify, acquire and advance new assets
and for working capital and general corporate purposes.

In connection with the Purchase
Agreement, we entered into a Registration Rights Agreement (the “Registration Rights Agreement”) with the Selling Shareholders
pursuant to which we agreed to file a registration statement (the “Registration Statement”) registering the resale of the
shares of Common Stock and the shares of Common Stock issuable upon exercise of the Pre-Funded Warrants within 15 days following the Closing
Date, and to use our best efforts to cause the Registration Statement to be declared effective by the SEC within 60 days following its
filing (or 90 days if reviewed by the SEC).

| 2 | |

With limited exceptions, we
have agreed not to enter into or announce any transaction for the sale of any of our equity securities or securities convertible into
our equity securities for a period of 120 days from the effective date of this registration statement. In addition, we have agreed not
to effect or enter into an agreement to effect any issuance of our common stock or any securities convertible into or exercisable or exchangeable
for shares of Common Stock involving a Variable Rate Transaction (as defined in the Purchase Agreement) until one year after the Closing
Date; provided that after 120 days from the effective date of the Registration Statement, we will be permitted to make sales under any
“at-the-market offering” sales agreement with AGP (as defined below).

On May 4, 2026, we entered
into a placement agency agreement (the “Placement Agreement”) with A.G.P./Alliance Global Partners (the “Placement Agent”
or “AGP”), pursuant to which we paid the Placement Agent a cash fee equal to 7.0% of the gross proceeds from the Private Placement
and reimbursed the Placement Agent for $75,000 of fees and expenses and $15,000 of non-accountable expenses.

We are filing the registration
statement of which this prospectus forms a part in order to satisfy our obligations to the Selling Shareholders under the Registration
Rights Agreement. The registration statement registers the resale by the Selling Shareholders of the shares of common stock issued in
the Private Placement and the shares of common stock issuable upon exercise of the Pre-Funded Warrants. We will not receive any proceeds
from the resale of these shares by the Selling Shareholders, although we may receive nominal proceeds upon any cash exercise of the Pre-Funded
Warrants.

|
|
|

Risk factors: |
|
An investment in our securities involves substantial risk. You should read carefully the “ Risk Factors ” section on page 5 of this prospectus, and under similar headings in the other documents incorporated by reference into this prospectus. Additional risks and uncertainties not presently known to us or that we currently deem to be immaterial may also impair our business and operations. |

|
|
|

Nasdaq Capital Market symbol: |
|
Our common stock is listed on The Nasdaq Capital Market under the symbol “CNSP”. There is no established public trading market for the Pre-Funded Warrants, and a market will likely never develop. The Pre-Funded Warrants are not and will not be listed for trading on the Nasdaq Stock Market, any other national securities exchange or other nationally recognized trading system. |

The number of shares of common
stock outstanding is based on 1,461,449 shares outstanding as of May 14, 2026, and excludes the 9,143,479 shares issuable upon exercise
of the Pre-Funded Warrants, as well as:

| · | 333,930 shares of common stock underlying outstanding warrants at a weighted average exercise price of
$90.72 per share; |

| | |

| · | 14,961 shares of common stock underlying outstanding options with a weighted average exercise price of
$3,289.55 per share, which options vest over a three to four-year period; |

| | |

RISK FACTORS

Before making an investment
decision, in addition to the risks set forth below, you should consider the “ Risk Factors ” included under Item 1A. of our
Annual Report on Form 10-K for the year ended December 31, 2025, and in our Quarterly Report on Form 10-Q for the quarterly period ended
March 31, 2026, and in our updates to those Risk Factors which are incorporated by reference in this prospectus, as updated by our future
filings with the SEC. The market or trading price of our common stock could decline due to any of these risks. In addition, please read
“ Cautionary Note Regarding Forward-Looking Statements ” in this prospectus, where we describe additional uncertainties
associated with our business and the forward-looking statements included or incorporated by reference in this prospectus. Please note
that additional risks not currently known to us or that we currently deem immaterial may also impair our business and operations.

Risks Related to this Offering

The number of shares being registered for
resale is significant in relation to the number of our outstanding shares of common stock.

We have filed a registration
statement of which this prospectus is a part to register the shares offered hereunder for sale into the public market by the Selling Shareholders.
These shares represent a significant number of shares of our common stock relative to our outstanding shares. The sale of all or a substantial
portion of these shares in the market within a short period of time could adversely affect the market price of our common stock during
the period the registration statement remains effective and could also adversely affect our ability to raise equity capital.

The exercise of the Pre-Funded Warrants
and the subsequent resale of the underlying shares could result in substantial dilution and further pressure on the market price of our
common stock.

The shares of common stock
issuable upon exercise of the Pre-Funded Warrants registered for resale under this prospectus represent a substantial number of additional
shares that may be issued and sold into the public market. The Pre-Funded Warrants are exercisable at a nominal exercise price and have
no expiration date, which may incentivize holders to exercise the Pre-Funded Warrants and sell the underlying shares when market conditions
permit. To the extent that these Pre-Funded Warrants are exercised and the underlying shares are sold, holders may experience dilution
in their ownership interests, and the availability of a significant number of additional shares for resale could adversely affect the
market price of our common stock.

| 5 | |

CAUTIONARY NOTE REGARDING FORWARD-LOOKING STATEMENTS

Some of the information in
this prospectus, and the documents we incorporate by reference, contain forward-looking statements within the meaning of the federal securities
laws. You should not rely on forward-looking statements in this prospectus, and the documents we incorporate by reference. Forward-looking

“future,” “intend,” “may,” “will,” “should,” “estimate,” “predict,”
“potential,” “continue,” and similar words, although some forward-looking statements are expressed differently.
This prospectus, and the documents we incorporate by reference, may also contain forward-looking statements attributed to third parties
relating to their estimates regarding the markets we may enter in the future. All forward-looking statements address matters that involve
risk and uncertainties, and there are many important risks, uncertainties and other factors that could cause our actual results to differ
materially from the forward-looking statements contained in this prospectus, and the documents we incorporate by reference.

Forward-looking statements
include, but are not limited to, statements about:

|
· |
our ability to secure rights to new pipeline assets via in-licensing, acquisition
or collaboration; |

|
|
|

|
· |
our ability to obtain additional funding to develop our product candidates; |

|

our ability to maintain compliance with the NASDAQ Capital Market’s continued listing requirements, including any new continued
listing requirements that are approved in the future; |

|
|
|

· |
the need to obtain regulatory approval of our product candidates; |

|
|
|

|
· |
the success of our clinical trials through all phases of clinical development; |

|
|
|

· |
compliance with obligations under intellectual property licenses with third parties; |

|
|
|

|
· |
any delays in regulatory review and approval of product candidates in clinical development; |

|
|
|

|
· |
our ability to commercialize our product candidates; |

|
|
|

|
· |
market acceptance of our product candidates; |

|
|
|

|
· |
competition from existing products or new products that may emerge; |

|
|
|

|
· |
potential product liability claims; |

|
|
|

|
· |
our dependency on third-party manufacturers to supply or manufacture our products; |

|
|
|

|
· |
our ability to establish or maintain collaborations, licensing or other arrangements; |

|
|
|

|
· |
our ability and third parties’ abilities to protect intellectual property
rights; |

|
|
|

|
· |
our ability to adequately support future growth; and |

|
|
|

|
· |
our ability to attract and retain key personnel to manage our business effectively. |

You should also carefully
consider the statements under “ Risk Factors ” and other sections of this prospectus, which address additional facts that could
cause our actual results to differ from those set forth in the forward-looking statements. We caution investors not to place significant
reliance on the forward-looking statements contained in this prospectus, and the documents we incorporate by reference. We undertake no
obligation to publicly update or review any forward-looking statements, whether as a result of new information, future developments or
otherwise.

| 6 | |

USE OF PROCEEDS

All shares of our common stock
offered by this prospectus are being registered for the account of the Selling Shareholders identified herein. We will not receive any
of the proceeds from the sale of these shares.

We will receive proceeds from
any cash exercise of the Pre-Funded Warrants, which, if exercised in cash with respect to all of the 9,143,479 shares of common stock
underlying the Pre-Funded Warrants, assuming all of the Pre-Funded Warrants are exercised for cash at the initial exercise price of $0.001
per share, would result in gross proceeds to us of a maximum of $9,143.48.

We intend to use any proceeds
received by us from the cash exercise of the Pre-Funded Warrants for working capital and general corporate purposes. As of the date of
this prospectus, we cannot specify with certainty all of the particular uses for the net proceeds to us from the cash exercise of the
Pre-Funded Warrants. Accordingly, our management will have broad discretion in the timing and application of these proceeds.

The holders of the Pre-Funded
Warrants may exercise the Pre-Funded Warrants at their own discretion and at any time and in accordance with the terms of the Pre-Funded
Warrants. The Pre-Funded Warrants have no expiration date and remain exercisable until exercised in full. As a result, we cannot predict
when or if the Pre-Funded Warrants will be exercised. In addition, the Pre-Funded Warrants are exercisable on a cashless basis. As a result,
we may receive little or no cash proceeds from the exercise of the Pre-Funded Warrants.

| 7 | |

SELLING SHAREHOLDERS

We are registering the shares
of common stock in order to permit the Selling Shareholders to offer the shares for resale from time to time. Except for the ownership
of the shares of common stock and Pre-Funded Warrants, the Selling Shareholders have not had any material relationship with us within
the past three years.

The table below lists the
Selling Shareholders and other information regarding the beneficial ownership of the shares of common stock by each of the Selling Shareholders.
The second column lists the number of shares of common stock beneficially owned by each Selling Shareholder, based on its ownership of
the shares of common stock and Pre-Funded Warrants, as of May 14, 2026, assuming exercise of the Pre-Funded Warrants held by the Selling
Shareholder on that date, without regard to any limitations on exercise.

The third column lists the
shares of common stock being offered by this prospectus by the Selling Shareholders.

In accordance with the terms
of a registration rights agreement with the Selling Shareholders, this prospectus generally covers the resale of the sum of (i) the number
of shares of common stock issued to the Selling Shareholders in the “Private Placement” described above and (ii) the maximum
number of shares of common stock issuable upon exercise of Pre-Funded Warrants, determined as if the outstanding Pre-Funded Warrants were
exercised in full as of the trading day immediately preceding the date this registration statement was initially filed with the SEC, without
regard to any limitations on the exercise of the Pre-Funded Warrants. The fourth column assumes the sale of all of the shares offered
by the Selling Shareholders pursuant to this prospectus.

Under the terms of the Pre-Funded
Warrants, a Selling Shareholder may not exercise the Pre-Funded Warrants to the extent such exercise would cause such Selling Shareholder,
together with its affiliates and attribution parties, to beneficially own a number of shares of common stock which would exceed 4.99%
or 9.99%, as applicable, of our then outstanding common stock following such exercise, excluding for purposes of such determination shares
of common stock issuable upon exercise of such Pre-Funded Warrants which have not been exercised. The number of shares in the second and
fourth columns do not reflect this limitation. The Selling Shareholders may sell all, some or none of their shares in this offering. See
“ Plan of Distribution .”

PLAN OF DISTRIBUTION

Each Selling Shareholder of
the securities and any of their pledgees, assignees and successors-in-interest may, from time to time, sell any or all of their securities
covered hereby on The Nasdaq Capital Market or any other stock exchange, market or trading facility on which the securities are traded
or in private transactions. These sales may be at fixed or negotiated prices. A Selling Shareholder may use any one or more of the following
methods when selling securities:

|
· |
ordinary brokerage transactions and transactions in which the broker-dealer solicits purchasers; |

|
|
|

|
· |
block trades in which the broker-dealer will attempt to sell the securities as agent but may position and resell a portion of the block as principal to facilitate the transaction; |

|
|
|

|
· |
purchases by a broker-dealer as principal and resale by the broker-dealer for its account; |

|
|
|

|
· |
an exchange distribution in accordance with the rules of the applicable exchange; |

|
|
|

|
· |
privately negotiated transactions; |

|
|
|

|
· |
settlement of short sales; |

|
|
|

|
· |
in transactions through broker-dealers that agree with the Selling Shareholders to sell a specified number of such securities at a stipulated price per security; |

|
|
|

|
· |
through the writing or settlement of options or other hedging transactions, whether through an options exchange or otherwise; |

|
|
|

|
· |
in distributions to members, limited partners or stockholders of the Selling Shareholders; |

|
|
|

|
· |
a combination of any such methods of sale; or |

|
|
|

|
· |
any other method permitted pursuant to applicable law. |

The Selling Shareholders may
also sell securities under Rule 144 or any other exemption from registration under the Securities Act, if available, rather than under
this prospectus.

The Selling Shareholders may,
from time to time, pledge or grant a security interest in some or all of the shares of common stock owned by them and, if they default
in the performance of their secured obligations, the pledgees or secured parties may offer and sell the shares of common stock, from time
to time, under this prospectus, or under an amendment to this prospectus under Rule 424(b)(3) or other applicable provision of the Securities
Act, by amending the list of Selling Shareholders to include the pledgee, transferee or other successors in interest as Selling Shareholders
under this prospectus. The Selling Shareholders also may transfer the shares of common stock in other circumstances, in which case the
transferees, pledgees or other successors in interest will be the Selling Shareholders for purposes of this prospectus.

Broker-dealers engaged by
the Selling Shareholders may arrange for other brokers-dealers to participate in sales. Broker-dealers may receive commissions or discounts
from the Selling Shareholders (or, if any broker-dealer acts as agent for the purchaser of securities, from the purchaser) in amounts
to be negotiated, but, except as set forth in a supplement to this prospectus, in the case of an agency transaction not in excess of a
customary brokerage commission in compliance with Financial Industry Regulatory Authority (“FINRA”) Rule 2121; and in the case
of a principal transaction a markup or markdown in compliance with FINRA Rule 2121.

| 10 | |

In connection with the sale
of the securities or interests therein, the Selling Shareholders may enter into hedging transactions with broker-dealers or other financial
institutions, which may in turn engage in short sales of the securities in the course of hedging the positions they assume. The Selling
Shareholders may also sell securities short and deliver these securities to close out their short positions, or loan or pledge the securities
to broker-dealers that in turn may sell these securities, and if such short sale shall take place after the date that this Registration
Statement is declared effective by the Commission, the Selling Shareholders may deliver securities covered by this prospectus. The Selling
Shareholders may also enter into option or other transactions with broker-dealers or other financial institutions or create one or more
derivative securities which require the delivery to such broker-dealer or other financial institution of securities offered by this prospectus,
which securities such broker-dealer or other financial institution may resell pursuant to this prospectus (as supplemented or amended
to reflect such transaction).

The Selling Shareholders and
any broker-dealers or agents that are involved in selling the securities may be deemed to be “underwriters” within the meaning
of the Securities Act in connection with such sales. In such event, any commissions received by such broker-dealers or agents and any
profit on the resale of the securities purchased by them may be deemed to be underwriting commissions or discounts under the Securities
Act. Each Selling Shareholder has informed the Company that it does not have any written or oral agreement or understanding, directly
or indirectly, with any person to distribute the securities.

The Company is required to
pay certain fees and expenses incurred by the Company incident to the registration of the securities. The Company has agreed to indemnify
the Selling Shareholders against certain losses, claims, damages and liabilities, including liabilities under the Securities Act.

We agreed to keep this prospectus
effective until the earlier of (i) the date on which the securities may be resold by the Selling Shareholders without registration and
without regard to any volume or manner-of-sale limitations by reason of Rule 144, without the requirement for the Company to be in compliance
with the current public information under Rule 144 under the Securities Act or any other rule of similar effect or (ii) all of the securities
have been sold pursuant to this prospectus or Rule 144 under the Securities Act or any other rule of similar effect. The resale securities
will be sold only through registered or licensed brokers or dealers if required under applicable state securities laws. In addition, in
certain states, the resale securities covered hereby may not be sold unless they have been registered or qualified for sale in the applicable
state or an exemption from the registration or qualification requirement is available and is complied with.

Under applicable rules and
regulations under the Exchange Act, any person engaged in the distribution of the resale securities may not simultaneously engage in market
making activities with respect to the shares of Common Stock for the applicable restricted period, as defined in Regulation M, prior to
the commencement of the distribution. In addition, the Selling Shareholders will be subject to applicable provisions of the Exchange Act
and the rules and regulations thereunder, including Regulation M, which may limit the timing of purchases and sales of the shares of Common
Stock by the Selling Shareholders or any other person. We will make copies of this prospectus available to the Selling Shareholders and
have informed them of the need to deliver a copy of this prospectus to each purchaser at or prior to the time of the sale (including by
compliance with Rule 172 under the Securities Act).

Item 15. Indemnification of Officers and Directors

The Registrant’s Articles
of Incorporation, as amended, and amended and restated bylaws provide for indemnification of directors, officers, employees or agents
of the Registrant to the fullest extent permitted by Nevada law (as amended from time to time). Section 78.7502 of the Nevada Revised
Statute provides that such indemnification may only be provided if the person acted in good faith and in a manner he or she reasonably
believed to be in, or not opposed to, the best interest of the Registrant and, with respect to any criminal action or proceeding, had
no reasonable cause to believe his conduct was unlawful.

Section 78.138 of the Nevada
Revised Statute provides that a director or officer is not individually liable to the corporation or its stockholders or creditors for
any damages as a result of any act or failure to act in his capacity as a director or officer unless it is proven that (1) his act or
failure to act constituted a breach of his fiduciary duties as a director or officer and (2) his breach of those duties involved intentional
misconduct, fraud or a knowing violation of law.

This provision is intended
to afford directors and officers protection against and to limit their potential liability for monetary damages resulting from suits alleging
a breach of the duty of care by a director or officer. As a consequence of this provision, stockholders of our company will be unable
to recover monetary damages against directors or officers for action taken by them that may constitute negligence or gross negligence
in performance of their duties unless such conduct falls within one of the foregoing exceptions. The provision, however, does not alter
the applicable standards governing a director’s or officer’s fiduciary duty and does not eliminate or limit the right of our
company or any stockholder to obtain an injunction or any other type of non-monetary relief in the event of a breach of fiduciary duty.

The Registrant currently has
directors’ and officers’ liability insurance.

Insofar as indemnification
for liabilities arising under the Securities Act may be permitted to directors, officers and controlling persons pursuant to the foregoing
provisions, or otherwise, the Registrant has been advised that in the opinion of the SEC such indemnification is against public policy
as expressed in the Securities Act and is, therefore, unenforceable.

Item 17. Undertakings

The undersigned registrant hereby undertakes:

(1) To file, during any period in which offers
or sales are being made, a post-effective amendment to this registration statement:

(i) to include
any prospectus required by Section 10(a)(3) of the Securities Act;

(ii) to reflect
in the prospectus any facts or events arising after the effective date of the registration statement (or the most recent post-effective
amendment thereof) which, individually or in the aggregate, represent a fundamental change in the information set forth in the registration
statement. Notwithstanding the foregoing, any increase or decrease in volume of securities offered (if the total dollar value of securities
offered would not exceed that which was registered) and any deviation from the low or high end of the estimated maximum offering range
may be reflected in the form of prospectus filed with the Securities and Exchange Commission (the “Commission”), pursuant
to Rule 424(b) if, in the aggregate, the changes in volume and price represent no more than 20 percent change in the maximum aggregate
offering price set forth in the “Calculation of Registration Fee” table in the effective registration statement; and (iii)
to include any material information with respect to the plan of distribution not previously disclosed in the registration statement or
any material change to such information in the registration statement;

| II- 2 | |

Provided, however ,
that paragraphs (a)(1)(i), (a)(1)(ii) and (a)(1)(iii) do not apply if the information required to be included in a post-effective amendment
by those paragraphs is contained in reports filed with or furnished to the Commission by the registrant pursuant to Section 13 or Section
15(d) of the Securities Exchange Act of 1934 (the “Exchange Act”), that are incorporated by reference in the registration
statement, or is contained in a form of prospectus filed pursuant to Rule 424(b) that is part of the registration statement.

(2) That, for the purpose of determining any liability
under the Securities Act, each such post-effective amendment shall be deemed to be a new registration statement relating to the securities
offered therein, and the offering of such securities at that time shall be deemed to be the initial bona fide offering thereof.

(3) To remove from registration by means of a
post-effective amendment any of the securities being registered which remain unsold at the termination of the offering.

(4) That, for the purpose of determining liability
under the Securities Act to any purchaser:

(i) Each prospectus
filed by the registrant pursuant to Rule 424(b)(3) shall be deemed to be part of the registration statement as of the date the filed prospectus
was deemed part of and included in the registration statement; and

(ii) Each prospectus
required to be filed pursuant to Rule 424(b)(2), (b)(5) or (b)(7) as part of a registration statement in reliance on Rule 430B relating
to an offering made pursuant to Rule 415(a)(1)(i), (vii) or (x) for the purpose of providing the information required by Section 10(a)
of the Securities Act shall be deemed to be part of and included in the registration statement as of the earlier of the date such form
of prospectus is first used after effectiveness or the date of the first contract of sale of securities in the offering described in prospectus.
As provided in Rule 430B, for liability purposes of the issuer and any person that is at that date an underwriter, such date shall be
deemed to be a new effective date of the registration statement relating to the securities in the registration statement to which the
prospectus relates, and the offering of such securities at that time shall be deemed to be the initial bona fide offering thereof. Provided,
however , that no statement made in a registration statement or prospectus that is part of the registration statement or made in a
document incorporated or deemed incorporated by reference into the registration statement or prospectus that is part of the registration
statement will, as to a purchaser with a time of contract of sale prior to such effective date, supersede or modify any statement that
was made in the registration statement or prospectus that was part of the registration statement or made in any such document immediately
prior to such effective date.

(iii) If the registrant
is subject to Rule 430C, each prospectus filed pursuant to Rule 424(b) as part of a registration statement relating to an offering, other
than registration statements relying on Rule 430B or other than prospectuses filed in reliance on Rule 430A, shall be deemed to be part
of and included in the registration statement as of the date it is first used after effectiveness. Provided, however , that no statement
made in a registration statement or prospectus that is part of the registration statement or made in a document incorporated or deemed
incorporated by reference into the registration statement or prospectus that is part of the registration statement will, as to a purchaser
with a time of contract of sale prior to such first use, supersede or modify any statement that was made in the registration statement
or prospectus that was part of the registration statement or made in any such document immediately prior to such date of first use.

(5) That, for purposes of determining any liability
under the Securities Act, each filing of the registrant’s annual report pursuant to Section 13(a) or Section 15(d) of the Exchange
Act that is incorporated by reference in the registration statement shall be deemed to be a new registration statement relating to the
securities offered therein, and the offering of such securities at that time shall be deemed to be the initial bona fide offering thereof.

(6) Insofar as indemnification for liabilities
arising under the Securities Act may be permitted to directors, officers and controlling persons of the registrant pursuant to the foregoing
provisions, or otherwise, the registrant has been advised that in the opinion of the Securities and Exchange Commission such indemnification
is against public policy as expressed in the Act and is, therefore, unenforceable. In the event that a claim for indemnification against
such liabilities (other than the payment by the registrant of expenses incurred or paid by a director, officer or controlling person of
the registrant in the successful defense of any action, suit or proceeding) is asserted by such director, officer or controlling person
in connection with the securities being registered, the registrant will, unless in the opinion of its counsel the matter has been settled
by controlling precedent, submit to a court of appropriate jurisdiction the question whether such indemnification by it is against public
policy as expressed in the Act and will be governed by the final adjudication of such issue.

| II- 3 | |

CNS Pharmaceuticals, Inc.

2100 West Loop South, Suite 900

Houston, Texas 77027

Ladies and Gentlemen:

We have acted as counsel to CNS Pharmaceuticals,
Inc., a Nevada corporation (the “Company”), in connection with the registration statement on Form S-3 (the “Registration
Statement”), filed by the Company on May 19, 2026, with the Securities and Exchange Commission (the “Commission”)
under the Securities Act of 1933, as amended (the “Securities Act”). The Registration Statement relates to the registration
for resale by the selling stockholders named in the Registration Statement (the “Selling Stockholders”) of up to (i) 650,000
shares (the “Shares”) of the Company’s common stock, $0.001 par value per share (“Common Stock”) and (ii)
9,143,479 shares of Common Stock issuable upon the exercise of certain outstanding warrants (the “Warrants”) issued by the
Company to the Selling Stockholders (the “Warrant Shares”).

In connection with our opinion, we have examined
the Registration Statement, including the exhibits thereto, the Warrants, and such other documents, corporate records and instruments,
and have examined such laws and regulations, as we have deemed necessary for the purposes of this opinion. In making our examination,
we have assumed the genuineness of all signatures, the authenticity of all documents submitted to us as originals, the conformity with
the originals of all documents submitted to us as copies and the legal capacity of all natural persons. As to matters of fact material
to our opinions in this letter, we have relied on certificates and statements from officers and other employees of the Company, public
officials and other appropriate persons.

Based on the foregoing and subject to the qualifications
set forth below, we are of the opinion that:

1. The Shares have been duly authorized
by all necessary corporate action of the Company, and are validly issued, fully paid and non-assessable; and

2. The Warrant Shares initially
issuable upon exercise of the Warrants when issued by the Company against payment therefor (not less than par value) in the circumstances
contemplated by the Warrants, will have been duly authorized by all necessary corporate action of the Company, and will be validly issued,
fully paid and non-assessable.

The foregoing opinions are limited to Chapter
78 of the Nevada Revised Statutes, and we express no opinion as to the laws of any other jurisdiction.

The opinions expressed in this opinion letter
are as of the date of this opinion letter only and as to laws covered hereby only as they are in effect on that date, and we assume no
obligation to update or supplement such opinion to reflect any facts or circumstances that may come to our attention after that date or
any changes in law that may occur or become effective after that date. The opinions herein are limited to the matters expressly set forth
in this opinion letter, and no opinion or representation is given or may be inferred beyond the opinions expressly set forth in this opinion
letter.

We hereby consent to the filing of this opinion
with the Commission as an exhibit to the Registration Statement and to the use of this firm’s name under the caption “Legal
Matters” in the Registration Statement. In giving this consent, we do not thereby admit that we are within the category of persons
whose consent is required under Section 7 of the Securities Act or the rules and regulations of the Commission promulgated thereunder.

Sincerely,

/s/ ArentFox Schiff LLP

ARENTFOX SCHIFF LLP
