Comorbidity

First-degree relatives elevated rates of Bipolar I Disorder (4-24%), Bipolar II Disorder (1-5%), and MDD (4-24%) Twin and adoption studies - evidence of genetic influence Polygenic models promising but core of BPD remains elusive Limbic system Amount of norepinephrine, serotonin, gamma-aminobutyric acid neurotransmitters are abnormal Actions of thyroid and other endocrine glands also account for nervous system changes Biorythms (body’s natural sleep and wake cycles) are erratic - may cause or result from chemical imbalances Damage to areas in brain responsible for emotional activity
Etiology: biological factors predominate

Stressful life events (onset and course)
Early onset 10% rapid cycling Families with high EE Lack of social support Number of previous episodes History of anxiety Persistence of affective
symptoms even when mood is relatively stable
Poor occupational functioning
Other Risk Factors

Mood-stabilizing meds sometimes prescribed with antipsychotic meds to treat BP I
Antidepressants - BP II
Medication

Improvements in 70% of clients Relatively short half life - must be taken
more than once per day Takes 2-3 weeks to establish effect Doesn’t preclude possibility of recurrence
• 36% recurrence rate in 5 yrs. • Combinations (with antidepressant, antipsychotic,
& anticonvulsant drugs) may help
Lithium prescribed for 1 year after first or second episode, permanent after third episode
Lithium Carbonate
![Page 11: Bi polar disorder jacqueline corcoran](https://reader035.fdocuments.in/reader035/viewer/2022062709/55902f3b1a28abd9508b4657/html5/thumbnails/11.jpg)
Difference between therapeutic and toxic levels is not so great
Monitoring monthly for 1st 4-6 months, every 6 mos. after that
Symptoms: thirst, weight gain, fatigue, hand tremor, muscle weakness, confusion, diarrhea, dizziness, nausea, slurred speech, spastic muscle movements
Importance of Monitoring Blood
Levels

Blocks norepinephrine reuptake, may also break down GABA
Advantages over lithium• stabilize mood in 2-5 days• as effective for stabilizing • more effective for maintenance• has a greater antidepressant effect
Side effects problematic - 50% not taking a year later
Anticonvulsants: Carbamazephine
![Page 13: Bi polar disorder jacqueline corcoran](https://reader035.fdocuments.in/reader035/viewer/2022062709/55902f3b1a28abd9508b4657/html5/thumbnails/13.jpg)
Comparable to lithium May be better than carbamazepine for
rapid cycling Trend toward prescribing
anticonvulsants as initial tx strategy
Anticonvulsants, cont.: Valproate
![Page 14: Bi polar disorder jacqueline corcoran](https://reader035.fdocuments.in/reader035/viewer/2022062709/55902f3b1a28abd9508b4657/html5/thumbnails/14.jpg)
Lithium, carbamazepine, and valproate all used with children
Prospects of chronic weight problems and long-term effects on kidney function need to be considered
