Why Alzheimer’s is not a single disease – and why that matters

Despite decades of research, there’s no consensus on what causes Alzheimer’s. But a new way of thinking is transforming how we study the condition, and could finally deliver effective treatments

Features

Alzheimer's disease. Series of coloured computed tomography (CT) scans of an axial section through the head of a 74-year-old patient with Alzheimer's disease. The front of the brain (brown) is at the top. Alzheimer's is a neurodegenerative disease and a common cause of dementia in the elderly. It causes brain atrophy (decrease in size), shown here by the enlarged ventricle cavities (white, at centre of brain) and the widened pale blue regions. The brain shrinkage caused by Alzheimer's disease leads to memory loss, confusion, personality changes and ultimately death. The cause of Alzheimer's disease is not known and there is no cure.

Treating Alzheimer's as having many causes may help us beat it
