TED-Ed: What is Alzheimer's disease? - Ivan Seah Yu Jun

Alzheimer's disease, the leading cause of dementia, affects millions globally. Discovered by Dr. Alois Alzheimer in 1901, it is characterized by plaques and tangles in the brain, leading to memory loss and cognitive decline. The disease progresses through various brain regions, causing symptoms like mood changes and hallucinations. Current research focuses on slowing progression, with treatments targeting acetylcholine breakdown and potential vaccines against plaques. Despite over a century of study, a cure remains elusive.
