Biological Explanation of OCD
- Genetics
Brain Abnormalities
- Biological Explanation of OCD
  - Genetics
Neurotransmitters
- Serotonin = important neurotransmitter for communication between neurons
High levels in the orbital frontal cortex = OCD
- Brain Abnormalities
Can be measured using PET scans
- Unethical - Injecting radioactive glucose into the bloodstream
Left frontal cortex
- High levels in the orbital frontal cortex = OCD
Low levels of Serotonin = OCD
- Neurotransmitters
  - Serotonin = important neurotransmitter for communication between neurons
- Too many neurotransmitters being passed onto the next neruon
  - Lots of Action Potential passed on
Studies?
- Twin studies
Adoption studies
- Studies?
  - Twin studies
High level of concordance = OCD is Hereditary
Some biological parents can't be found/ are willing to take part
- Adoption studies
The child might not know they're adopted - Unethical
Twins share the same environment, therefore there is already a high level of concordance
Treatment?
- Anti-depressent Drugs
  - SSRI (Selective Serotonin Reuptake Inhibiters) - Prozac
Not sure whether this is the Cause or Effect of OCD
Area where information is converted from the senses into thoughts
Behavior could be learnt through others or their environment - Ignores environmental factors
Very Scientific
