Heavy Drinking Linked to Abnormal Brain Development


Posted on: Thu 08-12-2016

Teenragers who drink eavily are more likely than their peers to have less gray matter an important brain structure that aids in memory, decisions, and self-control. This is the findings of a study published in the journal Addiction'. 
 
The study was observational, so it is impossible to say whether heavy drink-ing caused this stunted brain development. People may have less brain matter due to genetic factors, and this abnormality may make them more likely to abuse alcohol. 
 
Reacting, Lead Author, Noora Heikkinen of the University of Eastern Fin-land said, "Substance use has been found to be con-nected to social exclusion, mental health problems and lower educational at-tainment.
 
"Having less gray matter may cause similar prob-lems, as gray matter con-tains most of the brain's neurons and plays an im-portant role in memory, emotions, decision-mak-ing, and self-control. 
 
He added: "Brain structural changes might be one factor that con-tributes to the social and mental problems among substance-using individuals."
