An observational study, which has not yet been peer-reviewed, hints that there is no safe level of drinking for the brain. Even moderate intake of alcohol can adversely affect nearly every part of the brain.
For the study, the researchers analysed the relationship between the self-reported alcohol intake of more than 25,000 people in the UK and their brain scans. During the study, they noted that drinking can have a severe effect on the brain’s gray matter.
Gray matter or grey matter is a major component of the central nervous system, consisting of neuronal cell bodies, neuropil, glial cells, synapses, and capillaries. This area is vital for processing information in the brain and any abnormality in it may affect the way neurons function and communicate.
