Abstract:
Objective To evaluate the role of diffusion tensor imaging(DTI)in finding brain damage,and to explore the clinical features and cognitive function changes in patients with posttraumatic epilepsy.Methods The clinical data,collected from 175 outpatients with posttraumatic epilepsy and registered from June,1999 to August,2007 in General Hospital of PLA,were summarized.All the patients were divided into lesion identifiable group and lesion obscure group according to neuro-imaging results.The cognitive function of epilepsy group consisted of 37 posttraumatic epilepsy patients were compared with that of 37 age-matched healthy people.13 patients of the epilepsy group underwent DTI examination.Results Among all patients,the frequency of simplex partial and complex partial attacks were both significantly higher than that of secondary generalized seizures(P0.05).Compared with healthy control group,the patients in epilepsy group showed significantly lower VIQ,PIQ,PIQ,digit span score and digit symbol score,and longer reflex time in Stroop test and produced significantly less words in one minute(P
