Symptoms of Mania

Mania is characterized by a distinct period (≥7 days or requiring hospitalization) of abnormally elevated, expansive, or irritable mood PLUS abnormally increased activity or energy, accompanied by at least three additional symptoms (four if mood is only irritable) that represent a clear departure from baseline functioning and cause marked impairment. 1

Core Diagnostic Features

The primary criterion requires both abnormal mood AND abnormal energy/activity occurring together 1, 2:

  • Mood changes: Elevated, expansive, or irritable mood that is persistent and abnormal for the individual 1, 3
  • Increased energy/activity: This is now a mandatory core feature, not optional 1, 2
  • Duration: Must last at least 7 consecutive days, or any duration if hospitalization is required 4, 1

Cardinal Manic Symptoms

When the mood and energy criteria are met, at least three of the following must be present (or four if mood is only irritable) 1:

  • Reduced need for sleep – This is a hallmark sign, distinct from insomnia; patients feel rested after minimal sleep 4, 5
  • Grandiosity or inflated self-esteem – Unrealistic beliefs about one's abilities, importance, or power 1, 6
  • Pressured speech or increased talkativeness – Speech that is rapid, difficult to interrupt, and excessive 5, 6, 7
  • Racing thoughts or flight of ideas – Subjective experience of thoughts moving too quickly 5, 7
  • Distractibility – Attention easily drawn to irrelevant stimuli 1
  • Increased goal-directed activity or psychomotor agitation – Hyperactivity across multiple domains (social, work, sexual) 4, 6
  • Excessive involvement in pleasurable activities with high potential for harm – Reckless spending, sexual indiscretions, foolish investments 1, 8

Additional Clinical Features

Psychotic Symptoms

  • Delusions occur in 25-67% of manic episodes, while hallucinations occur in 13-40% 3
  • Psychotic features may include paranoia, confusion, or florid psychosis, and can be mood-congruent or mood-incongruent 4, 3
  • Manic psychosis is often misdiagnosed as schizophrenia, especially in adolescents 1

Mood Quality

  • Euphoria is the classic presentation – excessive happiness, optimism so severe that judgment becomes impaired 8
  • Irritability can be the predominant mood, particularly in children and adolescents, but must be distinguished from chronic anger problems 4, 1
  • Mood lability with rapid, extreme shifts is common, especially in younger patients 4

Cognitive and Behavioral Changes

  • Thought disorder frequently accompanies hyperactivity and increased speech 6
  • Poor judgment and lack of insight often co-occur with grandiosity 6
  • The disturbance represents a significant departure from baseline functioning, not a reaction to situations 4, 1
  • Impairment must be evident across multiple settings (home, work, social), not isolated to one domain 4

Critical Diagnostic Distinctions

What Mania Is NOT:

  • Not situational reactivity – True mania is a pervasive change in mental state, not anger in response to specific triggers 4
  • Not chronic temperament – Must represent a distinct episode, a break from pre-morbid functioning 4, 3
  • Not substance effects alone – Symptoms directly attributable to drugs or medical conditions don't count, though antidepressant-induced mania should be classified as substance-induced 1, 5

Key Differentiating Features:

  • The presence of euphoria or grandiosity strongly suggests bipolar disorder over other causes of irritability and agitation 4, 5
  • Reduced need for sleep (feeling rested after 2-3 hours) is more specific than insomnia 4
  • Psychomotor, sleep, and cognitive changes must accompany the mood disturbance in true mania 4

Special Considerations by Age

Adults:

  • Episodes represent a cyclical pattern with distinct episode boundaries and clear departure from baseline 4
  • More classic presentation with clearer symptom clusters 4

Adolescents:

  • Frequently associated with psychotic symptoms 4
  • Markedly labile moods with mixed manic and depressive features 4
  • More chronic and refractory to treatment than adult-onset cases 4

Children:

  • Irritability, belligerence, and mixed features are more common than euphoria 4
  • Episodes may be extremely brief (hours to days) or present as chronic baseline patterns 4
  • Must differentiate from normal childhood phenomena: boasting, imaginary play, overactivity, youthful indiscretions 9, 4
  • High comorbidity with ADHD and disruptive behavior disorders complicates diagnosis 9, 4

Common Diagnostic Pitfalls

  • Irritability alone is nonspecific – It occurs across many psychiatric conditions and lacks diagnostic specificity for mania 4, 5
  • Hyperactivity without episodic mood change suggests ADHD, not mania 4
  • Chronic anger problems in disruptive behavior disorders lack the distinct episodic nature and associated manic symptoms 9, 4
  • Clinicians must require either euphoria or grandiosity when evaluating irritable presentations to avoid over-diagnosis 4
