The brain has an internal drain which needs to be kept clear to prevent neurodegenerative diseases like Alzheimer’s, scientists believe.
Researchers at University College London (UCL) have discovered a combination of sleep, exercise and a small amount of alcohol all help stimulate the ‘brain drain’, preventing the dangerous build up of sticky plaques which drive dementia.
Scientists have known for some time that regular exercise and getting a good night’s rest help prevent mental decline, but until now did not know how.
