Question 6

Question
[blank_start]Amine[blank_end] Hypothesis  Abnormally low levels of norepinephrine and/or [blank_start]serotonin[blank_end] underlie [blank_start]depression[blank_end] Evidence for this hypothesis includes:  Reserpine, an (old) antihypertensive drug depletes pre-synaptic stores of [blank_start]norepinephrine[blank_end] (NE) and is associated with depressive symptoms.  Autopsy studies of the brains of depressed suicide victims indicate a [blank_start]low[blank_end] level of NE and/or serotonin (5-HT) metabolism in most brain regions  Drugs found to be beneficial act to enhance NE or 5-HT levels. A major weakness to this hypothesis is the therapeutic lag – effects of drugs on NE or 5-HT levels are observed [blank_start]immediately[blank_end] yet therapeutic benefit takes a minimum of 1 to 4 [blank_start]weeks[blank_end] to occur
Answer
  • Amine
  • serotonin
  • depression
  • norepinephrine
  • low
  • immediately
  • weeks

Question 7

Question

Answer
  • Neuroendocrine
  • cortisol
  • HPA
  • thyroid

Question 8

Question
[blank_start]Neurotrophin[blank_end] Hypothesis  Laboratory research indicates that antidepressants [blank_start]increase[blank_end] BDNF production in [blank_start]hippocampus[blank_end]  This requires [blank_start]long[blank_end] term (weeks) not [blank_start]short[blank_end] term (days) treatment  BDNF increases neurogenesis and [blank_start]synaptic[blank_end] connectivity  Stress, pain and depression can [blank_start]reduce[blank_end] BDNF  Imaging studies indicate reduced hippocampal volume (size) in [blank_start]depression[blank_end]
Answer
  • increase
