Medical Tests for Diagnosing Alzheimer's

There is no single test that can definitively determine whether a person has Alzheimer’s disease or another form of dementia. Diagnosing these complex conditions requires a careful combination of diagnostic tools, clinical evaluations, imaging, and laboratory testing. Physicians rely on a comprehensive assessment that includes medical history, physical exams, cognitive and behavioral assessments, brain scans, and sometimes even spinal fluid or blood tests.
