Study Notes
Bipolar Disorder Symptoms
- Mania (Bipolar I): Characterized by elevated or irritable mood, increased energy and activity, inflated self-esteem, decreased need for sleep, pressured speech, racing thoughts, impulsivity, poor judgment, and in extreme cases, delusions or hallucinations.
- Hypomania (Bipolar II and Cyclothymia): Similar to mania but less severe and shorter in duration, without significant impairment in social or occupational functioning.
- Depressive Episodes (Bipolar I, II, and Cyclothymia): Persistent sadness, hopelessness, loss of interest, fatigue, appetite and weight changes, sleep disturbances, difficulty concentrating, and suicidal thoughts or behaviors.
Bipolar Disorder Treatment
- Pharmacological Interventions: Mood stabilizers, antipsychotics, antidepressants, and combination therapy.
- Psychotherapy: Cognitive-behavioral therapy (CBT) or psychotherapy can help patients manage their symptoms, improve coping skills, and gain insight into their condition.
- Lifestyle Modifications: Regular sleep schedules, healthy diet, exercise, minimizing stress, and avoiding alcohol and drugs.
Mood Stabilizers
- Lithium: First-line mood stabilizer, effective in managing acute mania and long-term stabilization. It modulates neurotransmission, promotes neuroprotection, and stabilizes mood.
- Pharmacokinetics: Well absorbed orally with a peak concentration in 1-2 hours.
- Adverse Effects: Tremor, nausea, diarrhea, polyuria, polydipsia, weight gain, cognitive effects, hypothyroidism, renal impairment, cardiac issues, and lithium toxicity.
- Toxicity: Occurs when serum levels exceed 1.5 mEq/L, causing tremors, confusion, nausea, seizures, and coma.
- Contraindications: Renal impairment, pregnancy, severe dehydration, sodium depletion.
- Valproate/ Valproic Acid: Anticonvulsant and mood stabilizer, used for acute mania, maintenance therapy, and epilepsy.
- Pharmacokinetics: Well absorbed orally, highly protein-bound, crosses the blood-brain barrier and the placenta.
- MOA: Inhibits sodium channels, enhances GABAergic activity, and modulates calcium channels.
- Adverse Effects: Nausea, vomiting, weight gain, tremor, hair thinning, hepatotoxicity, pancreatitis, hyperammonemia, thrombocytopenia, neurotoxic effects, and reproductive issues.
- Carbamazepine: Anticonvulsant and mood stabilizer used for epilepsy, bipolar disorder, and trigeminal neuralgia.
- MOA: Inhibits sodium channels, enhances GABAergic activity, reduces glutamate transmission, and influences calcium and serotonin pathways.
- Therapeutic Uses: Effective in controlling acute manic episodes, preventing recurrent manic episodes, and managing rapid-cycling bipolar disorder.
- Pharmacokinetics: Well absorbed orally with a slow onset of action.
- Adverse Effects: Dizziness, drowsiness, headache, blurred vision, hyponatremia, agranulocytosis, aplastic anemia, Stevens-Johnson syndrome (SJS), and toxic epidermal necrolysis.
