This means, adolescence is the time when the information processing speed and efficiency of the brain improves. Consumption of alcohol hampers this and has a negative effect on the physiological growth and development of the brain.

✦ In a study led by neuroscientist Susan Tapert of the University of California, San Diego, brain scans of teenagers who drank were compared with those of non-drinkers.
The nerve tissue of drinkers was found to have been damaged, translating into diminished attention span and reduced comprehension abilities. Tapert also showed that binge drinking among teenagers leads to deterioration in the quality of the brain's white matter.
