Family History of Alcoholism linked with Decreased Neuronal Activity

New research exploring the neural processes of adolescents with alcohol abuse in their family history has indicated that a positive family history may confer a significant risk for future alcoholism in the teenager!

Researchers examined teenagers that had not begun to drink, but had a family history of alcoholism, to rule out any brain differences caused by alcohol as a direct result.

In the experiment, the participants were required to prevent themselves from reading a color word out loud, and focus instead on the color of the ink the word was written in.

The researchers discovered that the teens with a familt history of Alcoholism showed higher levels of frontal lobe activation during the Stroop Interference test, suggesting they had decreased neuronal efficiency, meaning - to get the same score as the control group their brain had to work harder.
