Bad dreams in middle-age could be an early warning sign of cognitive decline, which could put you at a higher risk of developing dementia as you get older.
This is according to a new study which has looked at the correlation between distressing dreams, cognitive decline and risk of dementia.
The study was led by a University of Birmingham researcher and analysed more than 600 middle-aged adults aged 35 to 64, and 2,600 people aged 79 and older over a 13-year period.
