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.
Symptoms and signs
- Difficulty forming and retaining new memories
- Repeating questions
- Word-finding difficulty
- Getting lost in familiar places
- Difficulty with finances or medications
How it is evaluated
- History and neurological examination
- Cognitive and memory testing
- Laboratory studies to exclude other contributors
- MRI or CT of the brain when appropriate
- Alzheimer's biomarker testing when clinically indicated
When to seek care
- Progressive memory change that affects daily life should be evaluated.
- Sudden change in thinking or alertness requires emergency attention — call 911.
