4 Your Health: damage of obesity; college binge drinking; alcohol effect on dementia

Posted: Updated:

Years of heavy drinking can take a toll on the brain.

Researchers from France found alcohol abuse is a major risk factor for all types of dementia. They studied one million patients diagnosed with dementia over a five year period. About eight-percent of all cases were linked to alcohol abuse.

But alcohol played a role in more than half of patients with early onset dementia. 

Alcohol abuse begins in college

A new University Of Michigan study found students who lived in a fraternity or sorority house were much more likely to binge drink during college and later in life. 

They also had higher rates of marijuana use into their mid-thirties.

Years of obesity takes it's toll

A new study finds the number of years of being obese not just obesity is harmful to the heart. 

Researchers at Johns Hopkins University followed over 9,000 adults from their mid 20's through their mid 60's. People who were obese throughout their life were nearly four times as likely to have heart damage than those who maintained a normal weight.

Experts said losing weight even after decades of being obese may reverse some damage to the heart but more studies are needed.
