| Question | Answer |
| Factors | The Thalamus is associated with OCDs |
| McKeon and Murry | Interviewed people who scored high on the Leyton Obsessional Inventory from in families. The findings show OCD might not be connected to families |
| Carey and Gottesman | Reported a prevalence of up to 10% in 1st degree relatives |
| Lenane | 30% of first degree relatives in the study also had OCD's |
| Hoaker and Schnurr | Twin study, found a concordance rate of 50-60% Also found that when OCD's run in families they inherit the general nature of it but not the exact symptoms, shows there is an environmental effect |
| Dr. Dennis Murphy | 6 out of 7 people over 2 families that had a gene mutation of a serotonin transporter had an OCD. Also that some sufferers of the most sever OCD's had a second mutation in the same gene |
| Zohar | Some tricyclic drugs that inhibit the re-uptake of serotonin were beneficial for 60% of the OCD sufferers tested |
| Lydiard | Drugs only provide partial alleviation and therefore not a cure |
| Rapport and Wise | Suggests that OCD's result from dysfunction in the CNS, specifically the basal ganglia, the is supported by other disorders such as Huntingtons, Parkinsons and Touretts |
| Rapport | Surgery to disconnect the basal ganglia from the frontal cortex brought relief to people with severs cases of OCD |
| Evaluation | - Findings of effects of serotonin are inconsistent - Psychological therapies have been found to be effective - Aylward - Found no difference in the basal ganglia in OCD suffers and Non-OCD sufferers - No cause and effect link has been found - Head injuries and brain tumors have been associated with OCD's - Research into brain structures is still developing - Rapport - 20% of OCD suffers show nervous tics implying a link with the anatomy of the nervous system |
