Alzheimer's disease affected brain. Gloved hand holding a slice of brain affected by Alzheimer's disease. It is considerably shrunken compared to a healthy brain, and the fissures on the surface are unusually large. 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.
