Abstract：Objective To explore the difference of implicit memory between anorexia nervosa(AN) and depressive disorder. Methods Forty-two women patients with initial diagnosis of anorexia nervosa(n=21) or de-pressive disorder(n=21) were recruited from the inpatient unit of psychiatry department of the Third Affiliated Hospital of SUN Yat-sen University during September 2005 to October 2009. The processes dissociation procedure was applied to analyze the difference of implicit memory test in the two groups. Results In 21 patients with initial diagnosis of depressive disorder,3 were diagnosed of anorexia nervosa on discharge,showing a misdiagnosis rate of 14.3%. In other 21 patients with initial diagnosis of anorexia nervosa,5 were diagnosed of depressive disorder on discharge,showing a misdiagnosis rate of 23.8%. There were implicit memory bias in negative terms and vocabulary associated with anorexia nervosa in both groups [(0.65± 0.09) % vs (0. 55 ± 0.08) %,P＜0.05;(0.43 ±0.10)% vs (0.55±0.10)%,P＜0.01]. Conclusion Our study suggests that the bias in implicit memory test may be a practical tool for the differential diagnosis of the two diseases.
