The Biological Approach to explaining OCD

Question 1

What does the genetic explanation suggest?

Answer 1

We have a genetic vulnerability towards developing depression

Question 2

Answer 2

Of his OCD patients, 37% had parents with OCD and 21% had siblings with OCD

Question 3

WHat did Taylor find?

Answer 3

Question 4

Often associated with with the functioning neurotransmitters , like dopamine and serotonin which both regulate mood.

Question 5

Give a + (SETS)

Answer 5

Supporting evidence in twin studies it was found 68% of identical twins and only 31% of non-identical twins share OCD. Suggesting that there’s a genetic basis for this diseases identical twins share 100% DNA and non-identical share 50%

Question 6

Give a - (OIC)

Answer 6

Over 230 candidate genes that individually code for an increased risk of OCD, gives a practical issue that is hard to assess which genes have the greatest influence and which drugs should be used. Therefore this explanation is likely to have little value in the future

Question 7

Give a - (CIEF)

Answer 7
