Alcohol poses the greatest threat to brain health at 3 frames of a person’s life, according to new research.

During those 3 frames from conception to birth, from ages 15 to 19, and after 65 anni people undergo “dynamic” brain changes that may be particularly sensitive to the harmful effects of alcohol, researchers say.

Worldwide, about 10% of pregnant women drink. Heavy drinking during pregnancy can cause fetal alcohol spectrum disorder, and even low or moderate drinking during pregnancy is associated with poorer brain health and behavior in children, according to the authors of a paper published on 7 December in the BMJ journal.

More than 20% of teens ages 15-19 in wealthy nations report at least occasional binge drinking.

Research shows that binge drinking in the teen yrs is associated with reduced brain volume, poorer white matter development, critical for efficient brain functioning, and small to moderate shortfalls in a number of mental functions, the authors said.

In seniors, excessive drinking is 1 of the strongest modifiable risk factors for all types of dementia, particularly early-onset, compared with other risk factors such as high blood pressure and smoking.

Alcohol use disorders are relatively rare in older adults, but even moderate drinking is associated with a small but significant loss of brain volume in midlife, according to the study author from the Centre for Healthy Brain Ageing at the University of New South Wales in Sydney, Australia.

The authors also said that current trends may increase the threat that drinking poses to brain health.

For example, women are now as likely as men to drink alcohol and suffer alcohol-related harm, and it’s predicted that worldwide alcohol consumption will rise further in the next 10 yrs.

How the COVID-19 chaos will affect alcohol use is unclear, but there have been long-term increases in drinking after other major public health crises, according to the authors.

They said an integrated approach to reducing alcohol-related harm at all ages is needed.

Population-based interventions such as guidelines on low-risk drinking, alcohol pricing policies, and lower drunk driving limits need to be accompanied by the development of training and care pathways that consider the human brain at risk throughout life,” the authors concluded in a journal news release.
