Importance Despite a remarkable co-occurrence of obsessive-compulsive disorder (OCD) and schizophrenia, little is known about the clinical and etiological relationship of these 2 disorders. Exploring the degree to which these disorders share etiological factors might provide useful implications for clinicians, researchers, and those with the disorders. Objectives To assess whether patients with OCD experience an enhanced risk of developing schizophrenia and schizophrenia spectrum disorders and to determine whether a family history of OCD constitutes a risk factor for schizophrenia and schizophrenia spectrum disorders.
Abstract: Literature evidence suggests that onset of obsessive–compulsive disorder (OCD) at a later age is usually associated with brain lesions. However, none of previous reports suggest an association between arachnoid cyst and OCD. In this report, we present a case of OCD, starting at the age of 40 years, in which the obsessive symptoms were characteristically associated with fluctuating insight

At least that was the explanation until 1913, when general paresis was shown to be caused by syphilitic infection of the brain
Abstract: Objective: The aim of this study is to assess the quality of life (QoL), family burden and psychiatric disorders in first-degree relatives of patients with obsessive–compulsive disorder (OCD) and to compare them with healthy controls and their relatives.Methods: Forty patients with OCD and 47 of their first-degree relatives as well as 40 healthy subjects and 45 of their first-degree relatives were recruited in this study. OCD and comorbid anxiety or mood disorders were determined by means of the Structured Clinical Interview for Diagnostic and Statistical Manual of Mental Disorders. Comorbid Axis II disorders were diagnosed with the Structured Clinical Interview for Diagnostic and Statistical Manual of Mental Disorders, Revised Third Edition Personality Disorders.
