Problems sleeping may be an early sign of Alzheimer's if a study in mice also applies to people, say researchers.

Clumps of protein, called plaques, in the brain are thought to be a key component of the illness.

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