Older men who report they struggle with disturbed sleep could be more likely to develop Alzheimer's in later life, according to new research.
A study that's published in the journal Alzheimer's & Dementia examined in excess of 1,000 men who were 50 years old at the beginning of the trial, which commenced in 1970.
Over the 40-year timeframe, self-reported sleep disturbances were linked to higher levels of Alzheimer's disease. Scientists believe a good night's sleep could be instrumental to brain health.
Sleep researcher at Uppsala University Christian Benedict, who led the study, said: "We demonstrate that men with self-reported sleep disturbances run a 1.5-fold higher risk to develop Alzheimer's disease than those without reports of sleep disturbances during a 40-year follow-up period."
In addition, the later in life that the disturbances were reported, the higher the likelihood of developing the degenerative disorder.
The scientists recommend maintaining a healthy lifestyle to help combat the onset of cognitive decline.
