Bipolar Disorder Overview

Diagnostic Criteria

• Bipolar disorder is characterized by episodes of mania or hypomania, often alternating with episodes of depression.
• Diagnostic criteria focus on the presence and duration of specific mood and behavioral symptoms.
• The DSM-5 (Diagnostic and Statistical Manual of Mental Disorders, Fifth Edition) provides the standard criteria for diagnosing bipolar disorder.
• Symptoms must significantly impair functioning and/or cause considerable distress to be considered clinically significant.
• Symptoms need to be present for a specified duration to meet diagnostic thresholds.

Types of Bipolar Disorder

• Bipolar I disorder involves at least one manic episode, which may or may not be followed by depressive episodes.
• Bipolar II disorder features at least one hypomanic episode alongside at least one major depressive episode.
• Hypomanic episodes share similar features with manic episodes but are less severe and do not cause significant impairment.
• Other specified and unspecified bipolar and related disorders: This category includes conditions that don't fully meet the criteria for other recognised bipolar disorders, but still involve mood-related symptoms.

Symptoms of Mania and Hypomania

• Mania involves elevated, expansive, or irritable mood, accompanied by increased energy and activity levels.
• Symptoms include inflated self-esteem, decreased need for sleep, talkativeness, racing thoughts, distractibility, involvement in high-risk behaviours.
• Hypomania shares similar symptoms to mania, but the symptoms are less severe and do not cause significant impairment in functioning.

Symptoms of Depression

• Bipolar disorder can also present with depressive episodes.
• Symptoms of depression include persistent low mood, loss of interest in activities, changes in appetite and sleep, fatigue, feelings of worthlessness, and recurrent thoughts of death or suicide.
• These depressive symptoms align with those seen in other forms of depressive disorders.

Differential Diagnosis

• Distinguishing bipolar disorder from other conditions is crucial for appropriate treatment.
• Conditions that might mimic bipolar disorder include:
  • Major depressive disorder
  • Schizoaffective disorder
  • Schizophrenia
  • Anxiety disorders
  • Substance use disorders.
• Proper diagnosis requires a comprehensive evaluation considering patient history, symptom presentation, and potential contributing factors.

Treatment Approaches

• Treatment strategies for bipolar disorder aim to stabilize mood and prevent future episodes.
• Medications play a vital role in managing mood fluctuations.
• Mood stabilizers, antipsychotics, and antidepressants are commonly used.
• Psychotherapy is often integrated with medication to address underlying psychological factors.
• Cognitive behavioural therapy (CBT) can help patients develop coping mechanisms and manage symptoms.
• Family-focused therapy can provide support and education to families of patients with bipolar disorder.

Medication Management

• Medication selection depends on the specific type and severity of bipolar disorder.
• Lithium is a widely used mood stabilizer for its effectiveness in preventing both manic and depressive episodes.
• Valproate and lamotrigine are other mood stabilizers used for their beneficial effects.
• Antipsychotics may also be prescribed, especially for managing acute manic or mixed episodes.
• Antidepressants are generally used cautiously in combination with mood stabilizers, as they may trigger manic episodes in some individuals with bipolar disorder

Ongoing Care and Support

• Managing long-term bipolar disorder involves ongoing monitoring and management.
• Close collaboration between patients, their families, and healthcare providers is essential.
