Study Notes
Bipolar Disorders
- Bipolar II involves at least one hypomanic episode and one major depressive episode.
- Cyclothymia disorder is a milder form of bipolar-related disorder, characterized by fluctuating symptoms of hypomania and mild to moderate depression lasting at least two years.
Mania
- Manic episodes include an euphoric or agitated affective state, often due to elevated dopamine levels.
- Common symptoms: racing thoughts, grandiose delusions, difficulty concentrating, impulsivity, lack of insight, and perceptual disturbances.
- Functional impairment is significant during manic phases.
Depressive Episodes
- Typically last longer than manic or hypomanic episodes.
Causes of Bipolar Disorder
- Genetic factors, neurodegeneration in regions like the thalamus and basal ganglia, neurotransmitter imbalances, stressful life events, substance abuse, and certain medications (e.g., TCA) contribute to the development of bipolar disorder.
Hypomania
- Characterized by a less severe affective state compared to mania, with lower levels of impairment.
Manic Episodes Criteria
- Must include increased energy and at least three additional symptoms such as decreased need for sleep, inflated self-worth, unusual talkativeness, racing thoughts, increased distractibility, and engagement in high-risk activities.
Mixed Episodes
- Mixed episodes represent the most severe form, with a high risk for suicide and poor prognosis.
Hypomanic Episodes Criteria
- Lasting at least four days with at least three symptoms, less severe than those in manic episodes.
Suicide Risk
- High in patients experiencing manic or hypomanic episodes compared to those with a melancholic presentation.
Early Detection Benefits
- Early identification of bipolar disorder can reduce substance use, suicide risk, and deterioration in social relationships.
Acute Mania Care
- During acute mania, priority is given to fulfilling physical needs.
Genetic Influence
- A significant genetic component is associated with the risk of bipolar disorders.
Adherence Support
- Support groups, psychoeducation, and family guidance can improve medication adherence for patients.
Treatment Options
- Mood stabilizers (e.g., lithium and anticonvulsants) are the first line of treatment for bipolar disorder.
- Lithium is effective for treating acute mania and for maintenance, with regular checks on blood levels (0.8-1.4), kidney, and thyroid functions.
- Antipsychotics and antidepressants are also used in treatment plans.
- Lamictal is utilized for maintenance therapy, while most anticonvulsants target acute mania.
Lithium Toxicity
- Early signs include diarrhea, vomiting, drowsiness, muscle weakness, and lack of coordination; severe toxicity may involve ataxia, tinnitus, and blurred vision.
- It's crucial to maintain adequate fluid and electrolyte balance while on lithium.
- Pregnant or breastfeeding women should avoid lithium use.
Schizophrenia Overview
- Requires at least one of the first two symptoms for a duration of one month.
Positive Symptoms of Schizophrenia
- Delusions, hallucinations, disorganized speech, and disturbances in behavior and thought processes.
Negative Symptoms of Schizophrenia
- Characterized by loss of interest, flat affect, lack of emotions, and decreased motivation (avolition).
Cognitive Symptoms
- Impaired cognitive functioning can also be a symptom of schizophrenia.
Epidemiology
- Schizophrenia is more prevalent in males, typically emerging between ages 15-25, with a significant impact on life expectancy.
Treatment for Schizophrenia
- Antipsychotics (both first and second generation) are the primary treatment, with second-generation being most common.
- Electroconvulsive therapy is recommended if pharmacological treatments are ineffective.
