Part II ISQ Club - Child Psychiatry

34 posts in this topic

Part II ISQs on two topics will be posted twice a week. You are encouraged to post a reply in the thread, stating whether you think an ISQ is true or false and why (eg. a short explanation, with reference to the textbook you used). Please only deal with one ISQ in each post and include the question as the first line of your post. All ISQs are taken from previous posts by Forum members.

In a few days this ISQ Club thread will be moved to the Question Bank board. If you submit an answer, your status will be changed to 'Question Bank member' and you will be able to see the Question Bank board. Please allow up to 48 hours for this change to happen.

14. Monozygotic heritability is 90% in autism

TRUE

“…the huge disparity in concordance rates for autism between MZ (n = 25) and DZ (n = 20) pairs (60% vs. 5%) confirmed the earlier findings on the strength of the genetic influence. Quantitative analyses indicated a heritability in excess of 90%.

http://www.findarticles.com/cf_dls/m0902/1_28/61969746/p2/article.jhtml?term=

“Current heritability estimates for autism are above 90%, which makes autism a strongly genetic disorder.”

17.Genetic locus heterogeniety is seen in juvenile deliquency... I would say its TRUE.

Dear Sandeep

Examinaton notes........... by Malhi says...... 1:14000 and says its the third commonest cause of mental retardation while Prader willi syndrome is 1:15000.... so if we go by your answer shall we assume Prader willi is the third commonest cause????

I know its all too confusing....... different books give different answers....

9. People with autism are unable to make direct eye to eye contact.

FALSE!!!

Goodman and Scott pg41

People with autism are able to make poor eye contact. Some are capable of direct eye to eye contact, though it may be brief. Also remember autism disorder is a SPECTRUM disorder
