Understanding how LEQEMBI fights Alzheimer's disease starts by taking a look inside the brain
Alzheimer's disease is a brain condition that gets worse over time. It may happen when a protein called amyloid continuously builds up in your brain, forming harmful amyloid brain plaque. Though there are different types of amyloid proteins, all of them can damage brain cells.

LEQEMBI works on fighting Alzheimer's disease in 2 ways
1
LEQEMBI targets the different types of
harmful amyloid proteins.

People taking LEQEMBI were shown to have less
amyloid brain plaque starting at 3 months.
