Not getting enough sleep can cause a person's brain to shrink, a new British study has found.
Researchers at Oxford University had 147 adults between the ages of 20 and 84 undergo two MRI brain scans an average of 3 1/2 years apart before completing a questionnaire about sleep habits.
The study found 35% of participants met the criteria for poor sleep quality and those with sleep difficulties experienced a more rapid decline in brain volume over the course of the study. The results were more pronounced in people over the age of 60.
The study was published online in the journal Neurology.
