decr gray matter in limbic sys
metabolism: ant cingulate v. PFC
NAA levels? lithium’s effect?
up in AC and down in PFC
low levels of N-acetylaspartate in PFC/AC/Hippo
lithium raises NAA by blocking ITP pathway –> release brake on new synapse formation

NEVER a manic episode
acute tx of mania
rapid mood stabilization
LITHIUM is gold std
anticonvulsants: VA and oxcarbazepine
atypical antipsychotics: risper/olanz/quetia/zipras/aripip (IF PT HAS PSYCHOTIC SX)
BZD’s adjuncts for anx/agitation/insomnia
ECT for rapid resolution of severe or refractory depression/mania
psychotherapy NOT effective
take pt off SNRI
acute tx of depressive episodes
NO ANTIDEPRESSANTS w/o a mood stabilizer: lithium, anticonvulsant, antipsychotic (lamotrigine)
psychotherapy
ECT
maintenance treatment of bipolar
kindling: episodes more freq/severe/refractory over time…so primary goal is to REDUCE mood episode recurrence
–> lithium, lamotrigine, VA, atypical apsychs
2/3 pts don’t adhere to first year of tx
bipolar co-morbid w?
substance use d/o –> may destabilize mood and result in recurrence
