Alzheimer’s disease is a progressive neurological disorder that leads to memory loss, cognitive decline, and ultimately, loss of ability to carry out simple tasks. Affecting millions of individuals worldwide, Alzheimer’s is the most common form of dementia, posing a major public health challenge. As the population ages, the prevalence of Alzheimer’s is expected to rise, making effective treatments more critical than ever.

Overview of Donanemab

Mechanism of Action

Donanemab is a monoclonal antibody designed to target amyloid-beta plaques in the brain, a hallmark of Alzheimer’s disease. These plaques are believed to play a crucial role in the disease’s progression by disrupting cell function and triggering inflammation. By binding to and facilitating the removal of these plaques, donanemab aims to slow cognitive decline and improve patient outcomes.
