    Study Notes

    Selecting Initial Treatment for Bipolar Disorder

    • The stepwise approach to selecting initial treatment involves:
      • Assessing client safety, comorbidities, and treatment adherence
      • Initiating and optimizing therapy, choosing monotherapy or combination, optimizing dose, and checking for adherence
      • Adding on or switching therapy, using alternate 1st line agents, adding on additional 1st line agents, or switching to 2nd line agents if 1st line agents are not effective

    Factors Associated with Nonadherence

    • Medication factors: adverse effects, low treatment doses
    • Manifestation of bipolar disorder: mixed episodes, rapid cycling, hallucinations, bipolar disorder 1
    • Comorbidities: substance abuse, obsessive-compulsive disorder
    • Demographics: male, younger, lower educational level, single
    • Other: poor insight, negative attitude, low self-esteem

    Medications for Bipolar Disorder

    • Lithium:
      • 1st line treatment for new onset bipolar disorder
      • Alerts transport in nerve and muscle
      • Effective in treating manic episodes, preventing reoccurrence, and to a lesser degree, depressive episodes
      • Has a narrow therapeutic window and requires lab draws
      • Well-established to help prevent suicide in clients with mood disorders
    • Lamotrigine (Lamictal):
      • Affects Na channel ion transport and enhances the activity of gamma-aminobutyric acid (GABA)
      • Equal in efficacy to lithium
      • Educate patients on potential symptoms: inflated self-esteem, increased goal-directed activity, grandiosity, decreased need for sleep, excessive talkativeness, flight of ideas, and propensity to be involved in high-risk activities
    • Carbamazepine (Tegretol):
      • Glutamate voltage-gated Na and Ca++ channel blocker (Glu-CB)
      • Consider genotyping patients with Asian ancestry, as the HLA-B 1502 allele increases the risk of SJS
    • Valproic acid (Depakene):
      • DA, NE, and 5-HT receptor antagonist
      • Affects ion transport and enhances the activity of GABA
      • If using with lamotrigine, decrease valproate levels by ½
    • Aripiprazole:
      • Appropriate for patients who struggle with adherence
      • IM after oral trial establishes tolerability

    Mood Disorders and Neurotransmitters

    • Mood disorders are characterized by abnormalities of mood, including depression, mania, or both
    • Mania: persistently elevated, expansive, or irritable mood
    • Symptoms of mania: inflated self-esteem, increased goal-directed activity, grandiosity, decreased need for sleep, excessive talkativeness, flight of ideas, distractibility, psychomotor agitation, and propensity to be involved in high-risk activities
    • Neurotransmitters affected by mood disorders: dopamine, norepinephrine, and 5-HT
    • Too little positive affect is associated with dopamine (DA) and norepinephrine (NE) dysfunction
    • Too much negative affect is associated with 5-HT and NE dysfunction
    • Symptoms of decreased positive affect: depressed mood, loss of joy, lack of interest, loss of energy, decreased alertness, decreased self-confidence, appetite changes
    • Symptoms of increased negative affect: depressed mood, guilt, fear, anxiety, hostility, irritability, loneliness, appetite changes

    Brain Regions and Functions

    • Nucleus accumbens: associated with racing thoughts, grandiosity, pleasure interests
    • Prefrontal cortex (PFC): associated with concentration, mental fatigue, mood, guilt, suicidality, worthlessness, risk-taking, talkative/pressured speech
    • Amygdala: associated with guilt, suicidality, worthlessness, mood
    • Striatum: associated with physical fatigue, motor/agitation
    • Hypothalamus: associated with sleep, appetite
    • Thalamus: associated with decreased sleep/arousal
