Biological Explanations

About the lecture

In this lecture, we think about the biological factors which may be involved in causing OCD, focusing in particular on: (i) the role of genes, discussing two research studies which suggest that OCD is heritable and polygenic, i.e. caused by more than one gene; (ii) two further studies which provide evidence for the thesis that genetics are a factor in causing OCD, whilst also highlighting the importance of gene-environment interaction; (iii) the neural mechanisms associated with OCD, in particular, the role of serotonin and how the abnormal functioning of the frontal lobe area of the brain may be linked to impaired decision-making in those suffering from the condition.
