Question: It should be mandatory for all candidates over age 50 to undergo genetic testing for Alzheimer's Disease (AD) before being placed on the ballot for President of the United States. As AD symptoms usually present in the mid-60's, all persons over age 50 could be Commander in Chief and need all their faculties. AD patients eventually have no control over their physical activities and require full-time care the majority of the time. "Changes in the brain can occur about 20 years before the onset of overt symptoms", said preventive neurologist Dr. Richard Isaacson, director of research at the Institute for Neurodegenerative Diseases in Florida (Howard, 2024, section 1Click and drag to move). NPR host, Steve Inskeep, recently discussed imposing age limits on elected officials because our current President and several congressional leaders/members recently had incidents similar to AD. These incidents are embarrassing and make the United States look weak. The key biomarker of Alzheimer's is called p-tau217, and is easily identifiable in a blood serum test at 96-97% certainty.
