Brain changes after stroke may lead to increase in alcohol-seeking behavior, at least in animal models, according to research published in the journal Scientific Reports.
Although it is known that excessive alcohol intake (more than two drinks per day) is a risk factor for stroke, there hasn’t been much scientific study about how alcohol-related behavior might change after a stroke has occurred. When researchers at the Texas A&M College of Medicine looked into the issue, they found that strokes in a certain part of the brain increase alcohol-seeking behavior and preference for alcohol.
“It’s important because although stroke is a severe disease, more and more people are surviving and recovering after their first stroke,” said Jun Wang, MD, PhD, assistant professor in the Department of Neuroscience and Experimental Therapeutics at the College of Medicine and co-principal investigator of this project. “Therefore, it is important to study behavior change after stroke, and how that behavior can affect the chances of having another one, which is often fatal.”
