Drug abuse has long-term effects on brain volume in women but not in men, a study says.
The researchers found that brain structures involved in reward, learning and executive control showed vast changes in women even after a prolonged period of abstinence from drug use.
“We found that after an average of 13.5 months of abstinence, women who were previously dependent on drugs had significantly less grey matter volume in several brain areas compared to healthy women,” said senior study author Jody Tanabe, neuroradiology section chief at University of Colorado.
