Prevalence of OCD Among Older Adults Reference

Boston College

Obsessive-compulsive disorder is characterized by intrusive thoughts that trigger repetitive and self-reinforcing behaviors. The obsessive component of this disorder can act as both an antecedent and a consequence, as the compulsive behavior is performed to quell the obsession, but ends up making the obsession even stronger. 

Obsessive-Compulsive Disorder (OCD) 

A study of community-dwelling older adults reported a 12-month OCD prevalence of 1.5%. The OCD group had a higher proportion of men than the anxiety- and mood-disorder comparison groups, poorer social functioning than same-age adults with anxiety disorders, and lower health-service use than older adults with other mental health disorders.

A significant comorbidity exists between obsessive-compulsive disorder (OCD) and major depressive disorder. Data shows that 41% of individuals with OCD also meet the diagnostic criteria for major depressive disorder. This relationship is often depicted in a Venn diagram, where the overlapping section of the two disorders' circles represents the percentage of co-occurrence.

Comorbidity of Obsessive-Compulsive Disorder and Major Depressive Disorder

A comprehensive understanding of obsessive-compulsive disorder requires knowledge of the various factors that contribute to its development. The origins of the disorder are complex and are thought to involve a combination of multiple influences.
