Pyschiatry II Flashcards
Which gene mutations are associated with schizo?
COMT/tyrosine hydroxylase/DA D2R/D3R
The ___ number of risk genes—->the high risk of getting schizo
Higher
Gene mutations that are responsible for hypofrontal activity of schizo?
COMT and DA D3R
Gene mutations that are responsible for hyper ventromedial cortex activity of schizo?
DA D2R/tyrosine hydroxylase/MAO
What are the significance of DA and NE in ADHD?
DA helps to block out out things/NE helps you to concentrate
Gene mutations that are associated with hypofrontal activity of ADHD?
DA D4/5R
What is the precursor of 5HT?
Tryptophan
5HT is from __ in the brain?
Raphe nuclei
Low 5HT causes hyperactivity in __ of the brain?
Amygdala
What gene mutations are associated with 5HT dysfunction?
5HT2a/5HTTLPR (reuptake transporter)/tryptophan hydroxylase
Where is NE originated in the brain?
Locus coeruleus
High NE gives you?
Hyperarousal/panic/worry
Dysfunction of what transmitters give you reduced + affect (loss of interest/happiness and what not)?
NE and DA
Dysfunction of what transmitters give you increased - affect (fear/irritability and what not)?
NE and 5HT
What is the brain activity of PTSD pt comparing with control?
High mid anterior cingulate and amygdala/low frontal activity
In MDD, what gene mutation is responsible for the increase NE and anxiety in limbic areas?
COMT Met alleles—>low degradation—>high NE (COMT Val alleles does the opposite)
What parts of the brain light up when you are empathizing?
Medial prefrontal cortex (hypoactive means you lack empathy)
Memorizing enhance or disrupt empathetic response?
Disrupt (maybe why doctors are not unempathetic when treating pts)
COMT is responsible for what transmitters?
DA and NE
