neural explanations to curing ocd

Question 1

The role of serotonin

Answer 1

One explanation for OCD concerns the role of the neurotransmitter serotonin, which is believed to help regulate mood. Neurotransmitters are responsible for relaying information from one neuron to another. If a person has low levels of serotonin then normal transmission of mood-relevant information does not take place and a person may experience low moods (and other mental processes may also be affected). At least some cases of OCD may be explained by a reduction in the functioning of the serotonin system in the brain.

Question 2

Decision-making systems

Answer 2

Some cases of OCD, and in particular hoarding disorder, seem to be associated with impaired decision-making. This in turn may be associated with abnormal functioning of the lateral (side bits) of the frontal lobes of the brain. The frontal lobes are the front part of the brain (behind your forehead) that are responsible for logical thinking and making decisions.
There is also evidence to suggest that an area called the left parahippocampal gyrus (see diagram on left), associated with processing unpleasant emotions, functions
