Alzheon, Inc.:

We consent to the use of our report included herein and to the reference to our firm under the heading “Experts” in the prospectus. Our report dated February 26, 2018 contains an explanatory paragraph that states that the Company has suffered recurring losses from operations and has an accumulated deficit, which raise substantial doubt about its ability to continue as a going concern. The financial statements and financial statement schedules do not include any adjustments that might result from the outcome of that uncertainty.
