Obsessive-Compulsive Disorder Characteristics
Demographics
- The American Psychiatric Association notes that OCD is actually more common in females than males in community epidemiological studies 1
- Clinical samples show a more even gender ratio, but this doesn't reflect true population prevalence 1
- Males do show earlier onset, with nearly 25% having onset before age 10, but this doesn't mean higher overall prevalence 2
Age of Onset
- The strongest predictor of lifetime OCD is actually age 18-29 years, not 30-40, according to the International OCD Foundation 2
- OCD typically starts early in life, with nearly 25% of males having onset before age 10 1, 2
- In females, onset often occurs during adolescence 1, 2
