Understanding potential side effects

When considering a new treatment, it’s okay to have questions about potential side effects. One side effect is ARIA. Take a look below to understand a bit more about it and how your healthcare provider will monitor you throughout treatment.

What is ARIA?

ARIA is a potential side effect of treatments like LEQEMBI. ARIA is most commonly seen as temporary swelling in areas of the brain that usually resolves over time.

Some people may also have small spots of bleeding in or on the surface of the brain and, infrequently,
larger areas of bleeding in the brain can occur.

Most people with this type of swelling in the brain do not get symptoms—however,
some people may have symptoms, such as:

Headache icon


Confusion icon

confusion that
gets worse

Dizziness icon


Vision problems icon

vision problems

Nausea icon


Footprint icon

difficulty walking

Seizure icon


Understanding the
role your genes play

A gene called ApoE4 may put people at higher risk for ARIA. Your healthcare provider can test to see if you have this gene. By understanding your risk, you can better prepare for treatment with LEQEMBI.

Monitoring for ARIA

Your healthcare provider will check for ARIA with MRI (magnetic resonance imaging) scans before your 5th, 7th, and 14th infusions. This gives them lots of opportunities to keep an eye on your brain health and manage your treatment.
