5. About 2/3 of mothers with post natal depression have bonding problems with their children - I'll say True

Royal College report, 2001

A new study has found that more than half of mothers with post-natal depression experienced some sort of interactive difficulties with their babies, a significant proportion of them suffered from the severe subtypes of mother-infant interaction difficulties. The remaining one-third of the mothers had normal relationships with their infants.

7. Children who don’t achieve handedness usually have bilateral speech centres - the 'usually' confuses things, but I would go with TRUE . See Ref.

Handedness is considered an indirect marker for bilateral language capacity in the brain.

Associations among Dissociative Experiences, Handedness, and Demographic Variables in a Nonclinical Population.

Journal of Nervous & Mental Disease. 188(7):422-427, July 2000.

1. Bipolar monozygotic twin will have 5% chance of developing schizophrenia - False

The numbers are:

The number is higher - 13%

The chance of developing mania is 40%

While for monozygotic twin of schizophrenic developing mania is 8%

And developing schizophrenia is 45%

8. Gender differences exist in the moral development of children - True

* Gilligan disliked the sexism in Kohlberg (based on male sample; females average Stage 3 and men Stage 4 on his tests).

* She argued that males show morality of justice, females morality of care, both of which are important.

* According to Gilligan, gender differences are learnt in childhood via identification with same-sex parent (father = authority figure, mother = caretaker).

Bottom line, gender differences do exist...

2. Salivary cortisol falls more than plasma cortisol in the dexamethasone suppression test - True

Found some stuff, but again its not cut and dry!

Where did you find these questions???

In the overnight LDDST, sensitivity and specificity for the diagnosis of Cushing syndrome versus normal controls is 100% and 87%, respectively, using a cut-off of 3.6 mg/dL (100 nmol/L) for plasma cortisol

100% for both sensitivity and specificity using a cut-off of 1.0 ng/mL (2.8 nmol/L) for salivary cortisol.

The LDDST is most useful in confirming the diagnosis of Cushing syndrome (i.e., distinguishing it from pseudo-Cushing syndrome) when the cortisol secretion is mildly increased; ???

Cheers Goob for the explanations

Still uncertain about these if anyone has an idea

3. Memory problems improve towards the end of a course of ECT

While more ECT would suggest worse memory it could also be improved by improving the mood. So who really knows the answer to this?

9. Carers are more likely to abuse a patient in an elderly nursing home if they are of the opposite sex

My only guess is that being an opposite sex may lead to feelings of projection and hostility against that person by ther carer - so possibly True

10. Heroin produces more euphoria than morphine due to increased potency at the mu receptor.

These both act at mu receptos, heroin could be more addictive and more euphoria due to increased potency could be an explanation but really don't know.
