Evaluation of the biological approach to treating OCD
1.Family and twin studies :
Chances of developing OCD increases if in the family
First degree relative- 5X more likely
Identical twins twice as likely to get OCD if twin had it as same genetics

Cause identified is correct
1. Concordance rates never 100% so environmental factors play a role in OCD
Can't be sure wether neurotransmitter imbalances cause OCD or opposite
3. Twin studies are flawed as genetic evidence
Twins share same environmental which can impact
