Symptoms of Mania

Mania is characterized by abnormally and persistently elevated, expansive, or irritable mood, accompanied by increased energy, decreased need for sleep, racing thoughts, and impaired judgment, representing a significant departure from baseline functioning and causing marked impairment. 1

Core Clinical Features

  • Mood changes - Marked euphoria, grandiosity, and irritability are cardinal symptoms of mania 1
  • Increased energy/activity - This is considered the core feature of mania, more so than mood changes 2
  • Decreased need for sleep - A hallmark sign that distinguishes mania from other conditions 1, 3
  • Racing thoughts - Often accompanied by pressure of speech and flight of ideas 1, 3
  • Impaired judgment - Leading to risky behaviors and poor decision-making 3, 4
  • Psychomotor agitation - Increased goal-directed activity 1, 5
  • Distractibility - Difficulty maintaining attention 1
  • Talkativeness - More talkative than usual or pressure to keep talking 1, 6
  • Excessive involvement in pleasurable activities with high potential for painful consequences 1

Diagnostic Criteria

For a formal diagnosis of mania, the American Academy of Child and Adolescent Psychiatry requires:

  • A distinct period of abnormally and persistently elevated, expansive, or irritable mood with increased activity or energy 1
  • Episode lasting at least one week (or any duration if hospitalization is required) 1, 5
  • At least three of the symptoms listed above (four if the mood is only irritable) 1
  • Symptoms represent a clear change from usual behavior 1
  • Symptoms cause marked impairment in functioning 1, 5

Presentation Variations

  • In adolescents: Mania frequently presents with psychotic symptoms, markedly labile moods, and/or mixed manic and depressive features 1
  • In younger children: Changes in mood, energy levels, and behavior are often more labile and erratic rather than persistent 1
  • Irritability and belligerence are more common than euphoria in juvenile presentations 1, 7
  • Mixed states: Complex syndrome with both manic and depressive symptoms occurring nearly every day for at least a one-week period 5
  • Psychotic features: One quarter to two thirds of all manic episodes are associated with delusions, while 13% to 40% are associated with hallucinations 5

Differential Diagnosis

  • ADHD: Can appear similar but represents a distinct condition 1, 7
  • Disruptive behavior disorders: May present with irritability and emotional reactivity 1
  • Posttraumatic stress disorder: Can mimic manic symptoms 1
  • Pervasive developmental disorders: May present with emotional dysregulation 1
  • Organic causes: Neurological disorders must be ruled out 1

Clinical Course and Prodromal Symptoms

  • Bipolar disorder with manic episodes is cyclical in nature 1
  • Common prodromal symptoms of mania include 8:
    • Decreased need for sleep
    • Increased activities
    • Being more sociable
    • Racing thoughts

Treatment Approaches

  • Lithium is indicated for the treatment of manic episodes and as maintenance therapy to reduce the frequency and intensity of future episodes 3
  • When given to a patient experiencing a manic episode, lithium may produce a normalization of symptomatology within 1 to 3 weeks 3
  • Current treatments aim to control agitation, impulsivity, aggression, and psychotic symptoms to help patients regain their pre-morbid functionality 5

Clinical Pitfalls to Avoid

  • Failing to distinguish between irritable mania and common anger problems 1
  • Confusing manic symptoms with those of ADHD 1, 7
  • Not recognizing that acute psychosis in an adolescent may be the first presentation of mania 1, 7
  • Applying adult diagnostic criteria to children without considering developmental context 1
  • Overlooking that most patients show syndromal remission but incomplete functional recovery after the first episode of mania 5
