Abstract


OBJECTIVES
The purpose of this study was to investigate the changes of cognitive dysfunctions in patients with obsessive compulsive disorder (OCD) over the two-year of pharmacological treatment.
METHODS
The thirty-three OCD patients and thirteen normal subjects were administered the neuropsychological tests and clinical evaluations twice (at the baseline and two-year).
RESULTS
In spite of the two-year treatment, the accuracy of delayed recall on the Rey-Osterrieth Complex Figure Tests (RCFT), the numbers of responses on the category and letter test of Controlled Oral Word Association Test (COWA), the response time on the Trail Making Test part A (TMT-A) remained significantly impaired in the OCD patients compared with the normal controls.
CONCLUSION
These findings suggest that the cognitive dysfunctions such as visuospatial memory and verbal fluency might be the underlying persisting neuropathophysiology of OCD.
