-rTMS: surgical implantation of device to treat MDD


-enhance mood by making catecholamines more avail by either inhibiting MAO enzymes or inhibiting neurotransmitter uptake, enhancing activation of adrenergic receptors
-also treat phobia, OCD, panic, anxiety
-must have black box warning to advise for warning signs of suicide (esp for children)
-classes: tricyclic antideps (TCAs), selective serotonin reuptake inhibs (SSRIs), atypical antideps incl serotonin-norepinephrine reuptake inhibs (SNRIs), monoamine oxidase inhibs (MAOIs)

tricyclic antidepressants (TCAs)

-inhibit the presynaptic reuptake of both norE and serotonin
-major depression & sometimes situational depression, and enuresis (bed wetting)
-side effects: orthohypo, sedation, anticholinergic effects

-inhibit serotonin & norE; but dopamine levels are also affected

monoamine oxidase inhibitors (MAOIs)

-inhibit monoamine oxidase, enzyme that terminates adction of dopamine, norE, and serotonin
-low safety margin, reserved 4 pts who are unresponsive to TCAs or SSRIs
