Outline of Final Research Achievements |
We studied to find genetic factors involved in clinical responses of obsessive-compulsive disorder (OCD) by using high resolusion proton magnetic resonance spectroscopy (MRS) and multichannel near infrared spectroscopy (NIRS). While we failed to detect specific genetic variants associated with clinical responses to SSRI or to SSRI with an atypical antipsychotic at genome-wide levels of significance, we identified 8 enriched pathways for the SSRI treatment response and 5 enriched pathways for the treatment response to SSRI with an antipsychotic medication. Moreover we found responders to SSRI showed different activation during the Stroop task compared to responders to SSRIs with antipsychotics by using NIRS. Our results may provide novel insight to predict clinical response in OCD patients.
