Question

Quizplus · Accepted Answer

A presumptive diagnosis of Alzheimer's disease is primarily based on a thorough history and physical examination, including neurological and cognitive function assessments. Imaging studies such as cerebral angiogram or echocardiogram may be used to rule out other underlying causes of cognitive decline, but they are not typically used in the initial diagnosis of Alzheimer's disease. Serum medication levels may also be evaluated to rule out medication-related cognitive impairment, but this is also not a definitive diagnostic tool for Alzheimer's disease.
