Alzheimer's disease affected brain. Gloved hands comparing a brain segment affected by Alzheimer's disease with a healthy one. The segment affected by Alzheimer's disease is on the left. It appears shrunken, and the fissures are noticeably larger. Alzheimer's disease is a progressive brain wasting condition which leads to the formation of tangles of nerve fibres and plaques of the protein amyloid. This interferes with the normal working of the brain leading to dementia, characterised by memory loss, personality changes, psychosis and eventually and inevitably death. It usually sets in around the age of 65, and there is no cure.
