Nastadt et al. (2000) identified 80 patients with OCD and 343 of their first detail relatives and compared them with 73 control patients without manpowertal illness and 300 of their relatives. on that point was a strong familial link for the about commonalty form of this disorder. People with a first stop relative with OCD (parents or siblings) had a five times great stake of having the illness themselves at some time in their lives compared with the common population.A meta-analysis of 14 mate studies of OCD, including 80 identical and 29 f considerrnal twin pairs, found that identical twins were on bonny more than twice as likely to machinate OCD if their twin had the disorder than were fraternal twins (Billett et al, 1998). The COMT gene:The variation in expressio n of a specific gene may work to OCD. This genetic alteration reduces the production of the enzyme catechol-O-methyltransferase (COMT), which helps terminate the proceeding of the neurotransmitters dopamine and norepinephrine. The researchers collected DNA from samples of 73 people diagnosed with OCD and 148 who had non go through any mental disorder.

The variation in the COMT genes usual sequence, inherited from both parents, occurred in nearly half(a) of the men suffering from OCD, whereas only 1 in 10 women with OCD, and about 1 in 6 of men and women who dis depended correct mental health, displayed t he same genetic trait. | integrity att! itude of the genetic explanation is that there is further empirical game provided by Rasmussen & Tsuang (1986). They found a concordance rate of 53-87% in MZ twins for OCD. This suggests that there is wider academic credibility for the image that genes play a significant role in the exploitation of OCD.| One weakness of the genetic explanation is the nature-nurture argument.
