PSY 240 Study Guide - Midterm Guide: Transcranial Magnetic Stimulation, Slow-Wave Sleep, Mania
Document Summary
Tricyclics (trofanil,elavil)- block norepinephrine & serotonin reuptake, sx. Monoamine oxidase (mao)- inihibits mao, interactions, less sx, specific. Ssri (prozac)- {1st}block serotonin reuptake, less likely sx, reduced sexual function. Ect: electrical current -> temp seizues, effective, common relapse; extreme cases. Transcranial magnetic stimulation: electromagnetic coil stimulates prefrontal cortex, not as effective as ect, sx= headache. Those with relatives w/ mood disorders = 2-3x greater than. Twin studies: more likely in identical twins that fraternal. One twin is unipolar, the chances of the second having bipolar is slim to none. Serotonin: (cid:373)oderator i(cid:374) depressio(cid:374) (cid:894)does(cid:374)"t (cid:373)ea(cid:374) its low(cid:895) Permissive hypothesis: something wrong with serotonin system: applied high levels of dopamine/norepinephrine. Overactive hpa axis elevated cortisol and suppressed hippocampal neurogenesis (breaks down) Huge estrogen & progesterone increase in pregnancy; suddenly drops after giving birth. Depressed = more alpha waves on right side, esp prefrontal cortex. Feel like they have no control of life. Need to take into consideration context, meaning & timing.
