Part II ISQ Club - Dementia/Delirum

21 posts in this topic

20 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.

In delirium, onset of rigidity and cogwheeling is due to nicotinic acid deficiency -so possibly true

nicotinic acid deficiency- (merck manual)

CNS symptoms include (1) organic psychosis, characterized by memory impairment, disorientation, confusion, and confabulation (excitement, depression, mania, and delirium predominate in some patients; in others, the reaction is paranoid); and (2) encephalopathic syndrome, characterized by clouding of consciousness, cogwheel rigidity of the extremities, and uncontrollable sucking and grasping reflexes. Differentiating these CNS changes from those in thiamine deficiency is difficult

wonder if biological psychiatry or organic psychiatry by lishman would have the answer

9. Pantothenic acid deficiency cause dementia/delirium

A metabolic antagonist of pantothenic acid, pantoyl g-amino butyric acid (called pantoyl-GABA, homopantothenate, or hopantothenate), is widely used in Japan as an anti-dementia drug for treating cognitive impairments in Alzheimer's disease, presumably through increasing cholinergic activity in vivo

1. Protozoal/Mumps/Cytomegalovirus/Recurrent urinary tract infections in pregnancy lead to cognitive impairment

I think this is true, as it explains the theory of intra uterine infection as a possile cause of developmental delays
