Neurovegetative symptoms seen in MDD are related to functions of the ______ and the _____ and the hormones they secrete
hypothalamus and pituitary
True or False: dysphoria is often triggered by changes in levels of sex steroids that occur during the menstrual cycle
True
In response to stress the hypothalamus releases ______, which stimulates the pituitary to release ______. This then stimulates the adrenals to release _______.
-CRH (corticotropin-releasing hormone)
-ACTH (adrenocorticotropic hormone)
-cortisol
True or False: hyperactivity of the HPA has been shown to be present in people with MDD
True,
HPA-axis controls physiological response to stress
-feedback pathways
Overtime, elevated ______ levels damage the CNS by altering neurotransmission and electrical signal conduction
cortisol
-can cause changes in size and function of brain tissue
True or False: MDD may be associated w/ proinflammatory cytokine activation
True
All of the following are possible NT function abnormalities causing depression except:
a. dysregulation of biogenic amine NTs b. low levels of endogenous catecholamines c. low levels of tryptophan d. high levels of 5HTIAA e. unusually high receptor sensitivity for NTs f. low density of receptor sites in certain areas
d. high levels of 5HTIAA, it is instead LOW levels of the serotonin metabolite 5HTIAA
True or False: structural changes in those w/ chronic/severe depression show hypovolemic hippocampus and prefrontal cortex-limbic striatal regions
True

True or False: antidepressant rebound is common when stopping abruptly, particularly w/ the drugs that have short half-lives
True
SSRIs act primarily to ______ by _______:
Increase serotonin levels in the CNS by inhibiting their presynaptic reuptake
TCAs act to ______ by ______:
Elevate serotonin and norepinephrine levels primarily by inhibiting their presynaptic reuptake
