A team of American psychologists(心理学家) and neuroscientists(神经系统学家) have found that adult brain volume, which can be reduced by Anorexia1 Nervosa(神经性食欲缺乏) , can be regained3. The research, published in the International Journal of Eating Disorders5, revealed that through specialist treatment patients with this eating disorder4 can reverse this symptom and regain2 grey matter volume. Anorexia Nervosa (AN) is a serious psychiatric eating disorder of excessive weight loss caused by relentless6(无情的,残酷的) dieting. The starvation that results from this illness affects physiological7 systems throughout the body, including the brain, but until now it has been unclear if and when brain volume reduction can be reversed through specialist treatment.

"Anorexia Nervosa wreaks8 havoc9(肆虐,造成破坏) on many different parts of the body, including the brain," said team leader Christina Roberto, MS, MPhil from Yale University. "In our study we measured brain volume deficits10 among underweight patients with the illness to evaluate if the decline is reversible thought short-term weight restoration(恢复,归还) ."

The team, based at the Columbia University Center for Eating Disorders used magnetic resonance11 imaging (MRI核磁共振成像) to take pictures of the brains of 32 adult female inpatients with Anorexia Nervosa and 21 healthy women without any psychiatric(精神病学的) illnesses.

The scans indicated that when the women with Anorexia Nervosa were in a state of starvation they had less grey matter brain volume compared to the healthy women. Those who had the illness the longest had the greatest reductions in brain volume when underweight.

"The good news is that when women with Anorexia Nervosa received treatment at a specialized12 eating disorders inpatient unit at Columbia University which helped them gain to a normal weight, the deficits in brain volume began to reverse over the course of only several weeks of weight gain," said Roberto. "This suggests that the reductions in brain matter volume that results from starvation can be reversed with appropriate treatment aimed at weight restoration."

The team's results reveal that underweight adult patients with AN have reduced brain volumes that increase with short-term weight restoration, however important questions still remain surrounding the link between brain volume reduction and anorexia.

"There is still plenty of research to be done. We do not yet have a good sense of the clinical implications of these reductions in brain volume," concluded Mrs. Roberto. "It is unclear how brain volume deficits impact functioning, which specific regions of the brain are most affected13 or if these deficits are linked to how patients respond to treatment."
