Flashcards in The biological approach to explain OCD Deck (12):
The genetic explanation to OCD
Stronger Biological Component. Individuals inherited specific genes from parents related to the onset of OCD.
Function of COMT GENE
Production of COMT/Regulates production of dopamine
How does the COMT predispose a person to OCD?
Variant. Tukel et al suggest the COMT gene lowers the production of COMT - Increases production of dopamine.
Function of SERT gene/ 5-HTT
Affects the transport of serotonin creating lower levels. These changed levels of serotonin affect OCD.

OCD has genetic biological cause but genetically speaking it’s not the sole reason why an individual develops OCD. The genes possessed creates genetic vulnerability. Environmental trigger and the gene is required to cause OCD.

Levels of key transmitters
What level of dopamine lead to OCD?
Conducted an animal study to, found high doses of drug enhanced dopamine levels, movement of animals resembled compulsive behaviours in OCD patients
What level of serotonin lead to OCD?
An antidepressant drug which increased the levels of serotonin activity reduced the symptoms of OCD
