Functional disorders in the frontal side were detected in the clinical evaluation of OCD with brain imaging systems. In this study, the effects of the OCD on the frontal part are investigated with Intertrial Phase Clustering (ITPC) method. According to the analysis results, significant loss of synchronization was found in all EEG bands for 6 electrodes on the frontal region. In addition, that these results are consistent with the results obtained by imaging devices, it was also indicated that decreased synchronization cause functional dysconnectivity. Besides, when evaluated together with the results of studies investigating the relationship between EEG waves and cognitive functions, it also indicates that OCD may cause many cognitive impairments, such as loss of memory and attention.trinfo:eu-repo/semantics/closedAccessObsesif Kompulsif BozukluklarBölütlerarası Faz Kümeleme YöntemiEEGObsessive Compulsive DisordersIntertrial Phase Clustering (ITPC) MethodEEGConference ObjectN/AWOS:000511448500318N/A
