Mood Swings

  • Definition and Characteristics

  • Types of Mood States
    • Severe mania
    • Hypomania (mild to moderate mania)
    • Normal/balanced mood
    • Mild to moderate depression
    • Severe depression

DSM-5 Criteria for Bipolar Disorder

Diagnosis of Bipolar I Disorder

  • Criteria for Manic Episode:
    • Distinct period of abnormally and persistently elevated, expansive, or irritable mood.
    • Accompanied by increased goal-directed activity or energy lasting at least one week, present most days and nearly every day.
    • Requires the presence of 3 or more of the following symptoms during the period of mood disturbance:
    1. Inflated self-esteem or grandiosity.
    2. Decreased need for sleep.
    3. More talkative than usual or pressure to keep talking.
    4. Flight of ideas or racing thoughts.
    5. Distractibility.
    6. Increase in goal-directed activities.
    7. Excessive involvement in potentially painful activities.

Mood Disorder Questionnaire

Instructions for Assessment

  • Complete the Mood Disorder Questionnaire (MDQ) accurately. The questionnaire includes questions about mood states and behaviors such as:
    • Feeling unusually good or hyper.
    • Increased self-confidence.
    • Decreased need for sleep.
    • Increased talkativeness.
    • Racing thoughts and inability to focus.
    • Increased sociability or risky behaviors.
    • Family history of manic-depressive illness.

Characteristics of Bipolar Disorder

Mania

  • Symptoms:
    • Mood: Elevated, expansive, irritable.
    • Speech: Loud and rapid, potentially including puns, rhyming, and clanging.
    • Possible weight loss, grandiosity, and delusions.
    • Hyperactivity and decreased need for sleep.
    • Flight of ideas escalates quickly over several days.

Depressive Episodes

  • Symptoms:
    • Mood: Dysphoric, despairing.
    • Lack of interest in pleasurable activities.
    • Negative cognitive biases and fatigue.
    • Changes in appetite, insomnia, and sexual desire.
    • May have suicidal preoccupations or experience agitation.

Etiology of Bipolar Disorder

  • The cause remains largely unknown.
  • Possible explanations include:
    • Genetically determined biochemical abnormalities in the brain.
    • Some drugs and physical health conditions can induce manic episodes.

Assessment Process

  • Key elements for assessment include:
    • Presenting symptoms and history of manic/depressive episodes.
    • Medication adherence and supporting clinical data.
    • New clients may require in-depth evaluation to develop a thorough treatment plan.

Clinical Manifestations of Mania

  • Mood changes during mania: Elevated, expansive, or irritable.
  • Behavioral characteristics: Talkative, excitable, energetic, often grandiose.
  • Possible engagement in indiscriminate and impulsive behaviors.

Types of Bipolar Disorder

Bipolar I Disorder

  • Mania and depression noted, with possible psychotic features.

Bipolar II Disorder

  • Defined by hypomania (less severe than mania) and episodes of major depression.

Manic Episode Criteria

  • Duration: At least one week of elevated mood.
  • Symptoms: At least three from DSM criteria with marked impairment in functioning.
  • Exclusion: Symptoms must not be due to substances or other medical conditions.

Hypomania

  • A milder state than mania, involves fewer symptoms and shorter duration with no marked impairment in functioning.

DIGFAST Mnemonic for Mania Symptoms

  • Distractibility
  • Insomnia (less need for sleep)
  • Grandiosity
  • Flight of Ideas
  • Activities (increased goal-directed behavior)
  • Speech (pressured talking)
  • Thoughtlessness (risk-taking behaviors)

Clinical Course of Bipolar Disorder

  • Mania tends to be shorter than depressive episodes.
  • Rapid cycling: More than four mood episodes per year.
  • Continuous cycling: Switching between mania and depression without normal periods of stabilization.

Social Prognosis for Individuals with Bipolar Disorder

  • Many individuals can work when stabilized.
  • Higher risk of unemployment and suicide compared to the general population.
  • Associated medical conditions can elevate risk of mortality.

Associated Disorders and Dual Diagnoses

  • Common comorbid conditions:
    • Substance abuse
    • Schizoaffective disorder
    • Borderline personality disorder
    • Chronic pain conditions
    • Cardiovascular diseases
    • Obesity
    • ADHD
    • Eating disorders
    • Impulse control disorders

Bipolar Disorder in Children

Diagnostic Challenges

  • Symptoms like chronic irritability can overlap with other conditions (e.g., ADHD, DMDD).

Genetic Risk

  • Higher risk if there is a family history of bipolar disorder (first-degree relatives).

Age of Onset

  • Average age of onset for bipolar disorder is around 25 years.
  • Prevalence in children and adolescents:
    • General prevalence in youth (ages 7-18): 1%-3%.
    • Adolescents (ages 13-18): Approximately 2.9% will meet criteria.
    • Early-onset (before age 12): True bipolar I is rare but may show early signs.

Pharmacological Treatments

Mood Stabilizers

  • Common medications:
    • Lithium
    • Valproic Acid
    • Lamotrigine
    • Carbamazepine
  • Mechanisms include stabilizing mood and monitoring for side effects.

Lithium Management

  • Importance of prescreening and monitoring for side effects:
    • Movement issues (tremors)
    • Kidney function and nephrogenic diabetes insipidus
    • Hypothyroidism
    • Pregnancy-related concerns (e.g., Ebstein's anomaly)

Lithium Toxicity

  • Signs of toxicity include: nausea, vomiting, lethargy, tremors, and changes in mental status.

Other Treatments for Acute Mania

  • May include benzodiazepines, neuroleptic agents, and additional mood stabilizers.

Psychotherapy

  • Role of therapeutic relationships in enhancing medication adherence.
  • Educating clients and their families about the disorder.

Inpatient Hospitalization

  • Importance of creating calm environments for manic clients.
  • Nursing approach: patience and respect for dignity.
  • Private rooms may be necessary for management.

Transitions of Care

  • Treatment settings include inpatient facilities, partial hospitalization, and home care.

Management Approaches

Physiological Management

  • Focus on medical interventions and medications.

Psychological Management

  • Focus on coping strategies and therapeutic engagement.

Evaluation of Treatment

  • Regular assessments of potential hazards.
  • Comparison of current functioning with baseline at the beginning of treatment.
  • Monitoring progress throughout recovery.

Conclusion

  • Thank you for attending the presentation on Bipolar Disorder.
