Researchers have called for an integrated approach to reduce alcohol consumption by people of all ages.
They say this is because alcohol consumption is bad for the brain at three stages of life.
They list these stages as conception to birth of the child, from age 15 to 19 and age 65 and above.
Alcohol they argue has far-reaching consequences on the child from a pregnant women who drink heavily or moderately.
One effect is fetal alcohol spectrum disorder and poor psychological disorder in children.
Persons in the age bracket 15-19 they say show defects in cognitive functions due to alcohol consumption.
As for those in the age 65 and above the consumption of alcohol accounts for risk factors in dementia.
