Bad sleep may predict Alzheimer's, says study


A study, published in the journal Science Translational Medicine, showed that when plaques first developed, the mice (trial on mice) started having disrupted sleep.

Problems sleeping may be an early sign of Alzheimer's — a form of dementia that gradually gets worse over time, say researchers. Clumps of protein, called plaques, in the brain are thought to be a key component of the illness.
