Alcohol Can Make Your Brain Smaller
Recent research done by neurologist Carol Ann Paul showed how brains size is affected by alcohol consumption. The research turned up interesting and highly controversial results.
The research took data from the Framingham Study, a long-term medical research project that followed residents of the town of Framingham, Massachusetts since 1948. Several years ago, the Framingham researchers took brain scans of people in the community who ranged in age from 34 to 88 years.
The 1800 people included in the study were divided into 5 groups:
- non-drinkers
- former drinkers
- low volume drinkers
- moderate drinkers
- heavy drinkers
The researchers measured total cranial volumes and the amount of space the subjects’ brains occupied inside their skulls. Brains normally get slightly smaller as people age, but Paul found the consumption of alcohol accelerated this process, even when she took other factors into account. And she says the more alcohol subjects drank, the more brain volume they lost.
There was no study to determine whether the shrinkage caused decreased brain function.
