New-onset depressive symptoms in a chronic case of obsessive-compulsive disorder in elderly – Case report

Obsessive-compulsive disorder (OCD) is often comorbid with various other conditions, some of which present later in the course. Therefore, a thorough evaluation of such new symptoms is necessary for overall management. Here we present a case report of a chronic case of OCD presenting with new-onset depressive symptoms in an elderly, finally diagnosed as a case of a brain tumor. Sudden and late onset obsessive–compulsive symptoms in patients with brain tumors have been described in the past, and this case highlights the need for neuroimaging in cases of OCD with new-onset depressive symptoms, particularly in the elderly.
