Question 6 of 33

Fill the blank spaces to complete the text.

Hypothesis
 Abnormally low levels of norepinephrine and/or underlie

Evidence for this hypothesis includes:
 Reserpine, an (old) antihypertensive drug depletes pre-synaptic stores of (NE) and is associated with depressive symptoms.
 Autopsy studies of the brains of depressed suicide victims indicate a 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 yet therapeutic benefit takes a minimum of 1 to 4 to occur
