About this Lecture

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.

Course

In this course, Dr Emma Sharpe (University of Derby) explores obsessive-compulsive disorder (OCD), a mental health condition characterised by obsessive thoughts and compulsive behaviours. In the first lecture, we think about how OCD can be defined and diagnosed. In the second lecture, we explore the behavioural, emotional and cognitive characteristics of the condition. In the third lecture, we examine the biological causes of OCD, looking in particular at genetic and neural explanations. Next, we think about how OCD can be treated, looking specifically at drug treatments. In the fifth lecture, we look at some key psychological treatments. In the sixth and final module, we conclude on some of the key points of discussion from the course.
