psychopathology NEURAL explanations for OCD

Question 1

STRENGTH, HAMBURGER, EXAMINE ANTIDEPRESSANTS

Answer 1

Supporting evidence for the role of serotonin comes from research examining antidep.
This research has found that drugs which increases the level of serotonin are effective in treating patients with OCD.
This suggests that serotonin is involved in OCD

Question 2

COMBO, PSSIBLE COMORBIDITY OF OCD-SEROTONIN LINK

Answer 2

The serononin-OCD link may be simply be co-morbidity with depression.
Many people who suffer from OCD become depressed . This depression probably involves but maybe not caused by disruption to the serotonin system.
It could be that in those with OCD, that serotonin system is disrupted because they are depressed as well.
But, the fact that the types if anti-depressants don’t work on the serotonin system have no effect pn OCD suggests that serotonin is directly involved in OCD and not just in accompanying depression.

Question 3

COMBO, DECISION MAKING SYSTSEMS INVOLVED WITH OCD

Answer 3

Caveolini et al (2002) looked at decision making and found that the neural system that are involved in decision making are the same systems that are functioning abnormally in those with OCD.
This suggests that these areas of the brain (an dtheir abnormal functioning ) are implicated in OCD.
However, no brain system has been found to always link to OCD so its unknown which neural mechanism are involved in the dev of OCD.
