- Neural explanations for OCD
- The pre frontal cortex is overactive in people with OCD. The PFC is responsible for decision making and primitive aspects of behaviour
- In people without OCD, the PFC becomes less active after certain behaviours e.g. getting rid of germs by washing hands
- Over-activity means the obsession with washing hands continues in people with OCD so they keep washing their hands when they don't need to
- In people without OCD, the PFC becomes less active after certain behaviours e.g. getting rid of germs by washing hands
- Info on SERT and COMT genes are relevant also.
- Salloway and Duffy did brain scans on people with OCD and found increased activity in PFC
- Cause and effect is difficult to establish with neurotransmitters.
