4.5: The biological approach to treating OCD Flashcards
The genetic explanation is the perception of OCD as transmitted through inherited factors.
Results from twin and gene-mapping studies indicate a genetic link to OCD, with particular genes being involved that make some individuals more vulnerable to developing the disorder than others.
These are called candidate genes, such as gene 9, COMT or SERT.
However, like many conditions, OCD seems to be polygenetic.
For example, Taylor (2013) has analysed the findings of previous studies and found evidence that up to 230 different genes may be involved in OCD.
One group of genes may cause OCD in one person, but a different group of genes may cause OCD in another person.
The term used to describe this is aetiologically heterogeneous.
In the general population, 2% have OCD.
However, among first degree relatives, the figure is 10%, indicating a genetic basis
There is research support for the genetic explanation for OCD.
For example, Lewis found that 37% of his OCD patients had parents with OCD and 21% of his OCD patients had siblings with OCD.
Twin studies also provide evidence, with concordance rates among MZ twins as high as 87%, compared to 47% with DZ twins.
However, family studies are flawed as evidence.
Concordance rates between MZ twins or even immediate family members are not 100%, suggesting that the genetic explanation is not valid.
