Environmental factors.
Brain structure and function.
What mutations in the hSERT gene have been linked to OCD?
Mutations in hSERT that increase the activity of the serotonin transporter have been linked to OCD. The theory is that the transporter is too effective, reuptaking serotonin at a rate that is faster than the general population, resulting in decreased levels of serotonin in the synapses.
Is OCD considered an anxiety disorder?
No.
Although, OCD is often comorbid with anxiety disorders.
I don’t know how I feel about this. From my experience anxiety was the major driver of my experiences with OCD.
Is CBT an effective treatment for OCD?
Yes. For some CBT can be very effective at helping individuals out of their struggles with OCD.
Is it true that 80% of the population may experience intrusive thoughts?
Yes. There are stats that suggest this.
The difference between individuals with OCD and the general population is that the former tend to resist these thoughts, identify with these thoughts, see these thoughts are a true reflection of who they are, are more intense in nature and more diametrically opposed to the individual’s values.
Those who experience intrusive thoughts often want to have complete control over their thoughts, they also find their intrusive thoughts threatening, and have a low tolerance for (certain) uncertainty.
T/F?
Yes.

Sometimes. Not always though.

For some, especially those concerned with contamination.
However, there was not a significant increase in new cases of OCD.
What is Body Dysmorphic Disorder?
Individuals experiencing BDD have a preoccupation with one or more bodily flaws that are not observable by others, or are only slight.
This fear is associated with repetitive behaviours, such as body checking, seeking reassurance, mental processes.
This preoccupation and the associated behaviour leads to significant distress, including shame.
Some people have muscle dysmorphia as a specifier to BDD. This is much more common in men than in women.
BDD has a very cultural element, as different cultures often have different beauty standard.
T/F?
True.
What is the prevalence of BDD?
0.7 - 2.4%.
