Sobering Conclusions: Alcoholism's Effects on Brain and Behavior
Posted September 07, 2006
Researchers have posited numerous hypotheses to explain the ways in which alcoholism affects the brain and behavior. Marlene Oscar Berman, a research career scientist at the Boston VA Medical Center, and director of the laboratory of neuropsychology at Boston University School of Medicine, has been working to test these hypotheses. In an April 17, 2006, meeting of the Academy's Psychology Section she shared observations from her experience in this field and summarized results of her studies.
Berman categorized her research into two areas. The first looks at models emphasizing the ways in which chronic alcoholism can make subjects vulnerable to premature aging. The second studies models emphasizing the vulnerability of specific brain regions, including the right hemispheric and frontal lobe systems. Berman emphasized that her research did not include active drinkers, but chronic alcoholic subjects who were sober, having abstained from drinking for at least a month.
