Investigation of EEG relative power spectral changes in obsesive compulsive disorder patients

Obsessive Compulsive Disorder (OCD) is a neuropsychiatrie disorder that usually negatively affects feelings and thoughts of adolescent adversely. Studies of OCD with imaging methods have found intense mental activity in the frontal region. In this study, relative power values are calculated for the channels representing the frontal regions. These values were compared with the data values of the data obtained from healthy volunteers. After statistical analysis, power values of OCD patients were found higher in the teta and alpha frequency regions than in the control group. These values found in the alpha band, which are known to be important for mental activities, show a good deal of previous work done with imaging methods.
