If elected, former President Donald Trump would become the oldest person in U.S. history to assume the presidency. In an opinion for The National Interest, Brig. Gen. (ret.) Stephen N. Xenakis, M.D., warns that Trump already shows the signs of cognitive decline, and his mental acuity is likely to erode even further over the next several years.    

Brig. Gen. Xenakis is an adult, child, and adolescent psychiatrist with many years of clinical, academic, and management experience. He is the Executive Director of APPA, an advisor for Physicians for Human Rights and the Center for Victims of Torture, and an Adjust Professor at Uniformed Services University of the Health Sciences. He is also a member of the CERL Executive Board. Read his bio here.
