- Recurrent, intrusive, and distressing thoughts or urges
- Repetitive behaviors such as checking, washing, counting, or mental rituals
- Significant interference with daily life, work, or social relationships
- Obsessions and compulsions may consume hours each day
- Individuals do not find pleasure in compulsive behaviors
- OCD is often a chronic condition, though symptom severity may fluctuate
- Treatment usually includes psychotherapy (especially CBT) and medication
- Early diagnosis and treatment improve long-term outcomes

- Also known as Major Depressive Disorder or clinical depression

What Is the Relationship Between OCD and Depression?
OCD and depression frequently occur together:
- Research suggests that 25–50% of individuals with OCD also experience depression
- In most cases, OCD symptoms appear first
- A smaller percentage experience both disorders simultaneously
- It is rare for depression to precede OCD
- Because of this pattern, depression is often considered a secondary condition resulting from OCD-related distress

Can Depression Cause OCD?
Current research does not support the idea that depression directly causes OCD.
Studies suggest OCD may develop due to:
- Genetic factors
- Differences in brain structure, particularly in frontal and subcortical regions
- Childhood trauma or chronic stress
- infections, such as streptococcal infections
