Checking your brain health

Your healthcare provider may use tests designed to evaluate your brain health and
help figure out if your symptoms are due to early Alzheimer’s disease.

Brain with magnifying glass icon

Cognitive exam

Checks how well your brain can think and process information.

Person and checklist icon

Neurological exam

Tests your nervous system, including your reflexes, speech, and sensations.

Lab tests

Test urine and blood to see if something else might be causing symptoms.

MRI (magnetic resonance imaging) scan

Takes a detailed picture of your brain for your healthcare provider to review.

These tests can help determine if LEQEMBI is right for you

Your healthcare provider will use one of the tests below to check for amyloid brain plaque. That’s because LEQEMBI keeps working throughout treatment to remove harmful amyloid brain plaque. So it’s important to know if amyloid brain plaque is behind your symptoms.

Positron emission tomography (PET) scan icon

Amyloid positron emission tomography (PET) scan

This test uses a special machine that takes pictures of your brain to check for amyloid brain plaque.

Cerebrospinal fluid (CSF) test icon

Cerebrospinal fluid (CSF) test

This test takes samples of the fluid around your brain and spinal cord to check for amyloid proteins that build up into amyloid brain plaque.

What's causing your symptoms?

Genetic test icon

Genetic test

A gene called ApoE4 may put people at higher risk for a side effect called ARIA (amyloid-related imaging abnormalities). Your healthcare provider can test to see if you have this gene. By understanding your risk, you can better prepare for treatment with LEQEMBI.
