Abstract:
Objective To investigate the characteristics of implicit and explicit memory in patients with obsessive compulsive disorder (OCD) and its relationship with obsessive-compulsive symptoms.Methods Thirty-one patients with OCD and thirty healthy participants matched with sex,age,years of education were enrolled in present study.All participants were conducted vocabulary perception speed task and vocabulary recognition task to evaluate the ability of implicit memory and explicit memory toward neutral,positive and moral disgust words.The accuracy and response time during tasks were recorded to index memory performance.The obsessive-compulsive symptoms were assessed with Padovar scale-Washington State University revised edition (PI-WSUR).Results There was significant difference in the response time of implicit memory between two groups ((2 926.63± 1 718.31) ms for OCD group,(2 587.13±1 054.56) ms for controls group,t=0.926,P=0.358).There was significant difference two groups in the accuracy of implicit memory for moral disgust words ((0.607±0.267) for OCD group,(0.777±0.159) for controls group,t=-3.306,P =0.004),positive words ((0.528±0.265) for OCD group,(0.695±0.152) for controls group,t=-3.048,P=0.004) and all words ((0.597±0.248) for OCD group,(0.731±0.145) for controls group,t=-2.582,P=0.013).The response time of explicit memory in OCD group was significantly correlated with PI-WSUR (r=-0.410,P=0.022),OTAHSO (r=-0.470,P=0.008).Conclusion Compared with healthy controls,the implicit memory of OCD patients was impaired,especially the implicit memory of positive emotion words and moral disgust words.There is no correlation between implicit memory and obsessive-compulsive symptoms in OCD patients.Compared with healthy controls,the implicit memory of OCD patients is not impaired,but there is a correlation between explicit memory and obsessive-compulsive symptoms in OCD patients.
