Why midlife nightmares are more than just a bad dream

There's a link with later congitive impairment

People with sleep disturbances in midlife may be more likely to develop cognitive impairment than those who get uninterrupted rest, say researchers.


After examining data from four studies, they found people with nightmares and insomnia in middle-age were more likely to experience cognitive impairment in old age than those who slept well.

They write in the journal Sleep Medicine that these sleep disturbances are associated with reduced Mini-Mental State Examination scores.
