Alzheimer's Disease results in sleepless nights and vice versa

Much before the actual symptoms of memory loss or other cognitive problems associated with Alzheimer Disease appear on the surface, the first symptom of this disease seems to be disrupted sleep pattern. The research was published in the journal Neurology.

Earlier studies also showed link mice between sleep loss and brain plaques. But the connection between the two is vice-versa. That implies that lack of sleep activates Alzheimer's plaques and the latter disrupts sleep.
