UK study of 25,000 people finds even moderate drinking is linked to lower grey matter density
There is no safe amount of alcohol consumption for the brain, with even “moderate” drinking adversely affecting nearly every part of it, a study of more than 25,000 people in the UK has found.
The study, which is still to be peer-reviewed, suggests that the more alcohol consumed, the lower the brain volume. In effect, the more you drink, the worse off your brain.
“There’s no threshold drinking for harm – any alcohol is worse. Pretty much the whole brain seems to be affected – not just specific areas, as previously thought,” said the lead author, Anya Topiwala, a senior clinical lecturer at the University of Oxford.
Using the UK Biobank, a substantial database designed to help researchers decode the genetic and environmental factors that lead some people to develop diseases while others do not, researchers in this study analysed data from 25,378 participants such as age, sex, education, self-reported alcohol consumption, brain size and health from MRI scans, information about hospital and outpatient visits, and memory tests.
