Describe Two Biological Explanations Of Ocd

Describe two or more biologic explanations of OCD (9 marks) The biological approach works on the assumption that kinkyity is caused by dysfunctional biological processes and that it is these factors mean that an illness is more liable(predicate) to occur in certain people. One explanation for OCD focuses on the role of genetics which argues that people are born with a pre disposition to scatter OCD. Evidence on genetics and OCD has deport-to doe with using oppose studies and outgrowth degree relatives. It has been found that those who have a first degree relative with OCD, much(prenominal)(prenominal) as parent of sibling, are 5 times more in all probability to have OCD themselves. This suggests that certain genetic factors may lead to abnormal public presentation of areas of the brain causing illnesses such(prenominal) as OCD. In addition, at that place is a high concordance rate in the thick of identical twins and they are twice as belike to develop OCD if their twin has the disorder compared to non identical twins. Therefore this same shows how there are certain genes that cause OCD and that these genes may be hereditary. Another explanation for OCD is Neuroanatomical processes involving the OFC caudate nuclei loop.

The loops involves the orbital facade cortex which picks up on situations that we need to worry most and then sends this message on to the Caudate Nucleus which describes whether or not the message is classic and if it deems yes, the message is passed on to the thalamus, which acts upon the on-going message. However in a faulty brain such as someone with OCD, the Caudat e Nuclei has tissue damage and so whenever i! t receives information from the Orbital Frontal Cortex, it deems the message as key and therefore an issue that needs to be dealt with. Because of this sufferers of OCD pop compulsions such as a repeated washing of their hands.If you want to confirm a full essay, order it on our website: BestEssayCheap.com
