Can a neurologist diagnose Alzheimer's disease?

Short answer

Yes. A neurologist diagnoses Alzheimer's disease by combining the history, a neurological examination, cognitive testing, laboratory studies, and brain imaging, with biomarker testing added when it is clinically appropriate.

Understanding this

There is no single test that stands alone. The diagnosis rests on the pattern of symptoms over time, the examination, and testing that both supports the diagnosis and excludes other causes.

Biomarker testing — blood-based, cerebrospinal fluid, or specialized imaging — can add information when the diagnosis is uncertain. Whether it is appropriate depends on the individual situation.

After the diagnosis is clarified, learn how dementia treatment may combine medical care, lifestyle support, safety planning, and caregiver education.

For confirmed early Alzheimer's disease, learn who may qualify for Leqembi or Kisunla and why amyloid, MRI, and APOE testing matter.
