repression vs. suppression
suppression= mature defense mechanism- don't think about something in order to get thru a task- *conscious repression= neurotic defense mechanism where you prevent a thought or feeling from entering consciousness- *unconscious

try ECT. it is an evidence based treatment for treatment refractory MDD. this is an emergency- not eating or drinking. also if pregnant or if suicide risk. it was have a rapid response, unlike drugs. it is safe alone and it can be used in conjunction with other medications.patients are given general anesthesia and an general tonic clonic seizure is induced.
what is a mixed episode of bipolar? treatment?
irritability is the predominant mood state. lithium is usually not effective. try an anticonvulsant like depakote (valproic acid)- these also work for rapid cycling mania

increases dopamine
SSRI and akathisia?
can cause it
increase action 5HT2 receptor-> decrease dopamine-> increase receptors for dopamine-> akathisia (?)

also stimulate alpha 1 somatodendritic receptors on serotonin neurons.
can cause weight gain and sedation
works in a diff way than ssri and snri- can add to them and i can be synergistic

need serotonin for platelets
anything that inhibits serotonin messes up platelets-> increases bleeding like GI bleeding or surgical bleeding
wan people, if on aspirin
remeron (mirtazapine) does not have that problem
