Hi. I had gone through your query. I understand your concern. Compulsive thought or obsessive thought may indicate OCD. OCD is obsessive and compulsive disorder in which repeated and persistent intrusion of thought occurs and you have to do compulsive behavior like repetition in response to it. Detail Psychological evaluation will give more confirmatory diagnosis. Scales like Y BOCS can help to find area of compulsion and its severity. Evaluation of mood/thought processes are also necessary. It can be treated with anti OCD medicines like fluoxetine and fluoxamine and clomipramine but selection is depend upon type and severity. Exposure and response prevention is also helpful psychotherapy in OCD. So consult psychiatrist and get help. I hope i have answered your query. Thank you. Regards. Dr. vishal Garala.
