Obsessive-compulsive disorder (OCD) arises from a complex interplay of factors. While the exact causes are not fully understood, several elements contribute to its development:
Genetics and Heredity:
- Inherited genetic factors play a role in predisposing individuals to OCD.
Brain Abnormalities:
- Chemical, structural, and functional abnormalities in the brain contribute to OCD.
- These brain changes impact neural circuits involved in decision-making, fear, and repetitive behaviours.
Distorted Beliefs:
- Erroneous beliefs reinforce and perpetuate OCD symptoms.
- Individuals may feel compelled to perform rituals or compulsions to alleviate distress caused by obsessive thoughts.
Environmental Factors:
- Stressful life events, trauma, or infections (such as streptococcal infections) may trigger or exacerbate OCD.
- Other mental health conditions like depression or anxiety can also influence its onset.
