P-1492 - Late Onset Obsessive Compulsive Disorder After Resection of a Right Frontal Meningioma

Abstract

Introduction:

Obsessive-comxulsive disorder (OCD) is relatively common and frequentlydisabling psychiatrix disoxder. Xxx onset of OCD is usually in adxlesence and earlyadulthood.Expxcially in cases with onset after age 40, the possibility of an underlyingmxdical causeshould be investigated (1).

Case report:

We report a casx whx developed late onset obsessive-compulsxve disorderaxtex resection of a frontal meningioma.

Discussion:

Some studies have investigated the devolopment of symptoms of OCD afterbrain injury.The majority of structural and functional imaging studies have demostrateddifferences in the frontal cortex- xspecially prefrontal coxxex- between patients with OCD andhealthy subjecxs (2); however in literature there are limited case reports which wereinvestigating the association between frontal brain tumors and OCD. In our case, patient hadno psychiatric history and interestingly the onset of OCD was after neurosuxgical treatmentand patient had not any cognitive disorder accompanxing to OCD.

Conclusion:

We argue that our case is important for demonstrating the direct associationbetween frxntal lobe and OCD and also it might have an xmporxance to give a viewpoint forxeuxosurgeons to screen patients for OCD after frontal brain surgery and for psychiatrixts toscreen caxefullx organic causes in patients xith late onset OCD.
