Mania: Clinical Features and Diagnostic Criteria

Core Clinical Features 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, according to the American Academy of Child and Adolescent Psychiatry 1, 2
Mood changes, including marked euphoria, grandiosity, and irritability, are the cardinal symptoms of mania, as noted by the American Academy of Child and Adolescent Psychiatry 2
Racing thoughts, increased psychomotor activity, and mood lability are characteristic associated symptoms of mania, as reported by the American Academy of Child and Adolescent Psychiatry 2
Marked sleep disturbance, typically presenting as decreased need for sleep, is a hallmark sign of mania, according to the American Academy of Child and Adolescent Psychiatry 1, 2

The American Academy of Child and Adolescent Psychiatry requires distinct periods of abnormally and persistently elevated, expansive, or irritable mood with increased activity or energy for a diagnosis of mania, with the episode lasting at least one week (or any duration if hospitalization is required) 3
Manic symptoms must include at least three of the following: inflated self-esteem or grandiosity 4, decreased need for sleep 5, more talkative than usual or pressure to keep talking 4, distractibility 4, increase in goal-directed activity or psychomotor agitation 4, and excessive involvement in pleasurable activities with high potential for painful consequences 3

In adolescents, mania frequently presents with psychotic symptoms, markedly labile moods, and/or mixed manic and depressive features, as noted by the American Academy of Child and Adolescent Psychiatry 1
In younger children, changes in mood, energy levels, and behavior are often more labile and erratic rather than persistent, according to the American Academy of Child and Adolescent Psychiatry 1
Irritability, belligerence, and mixed manic-depressive features are more common than euphoria in juvenile presentations, as reported by the American Academy of Child and Adolescent Psychiatry 1

Manic-like symptoms of irritability and emotional reactivity may be found in other conditions, including disruptive behavior disorders 6, posttraumatic stress disorder 5, and pervasive developmental disorders 3
Organic causes of mania, such as neurological disorders 6, must be ruled out

Bipolar disorder with manic episodes is cyclical in nature, according to the American Academy of Child and Adolescent Psychiatry 1, 2
Significant depressive symptoms may precede, occur conjointly (mixed episodes), or follow manic symptoms within the same episode, as noted by the American Academy of Child and Adolescent Psychiatry 2
The early course of bipolar disorder in adolescents appears to be more chronic and refractory to treatment than adult onset, as reported by the American Academy of Child and Adolescent Psychiatry 1

Failing to distinguish between irritable mania and common anger problems, especially given high rates of comorbidity with disruptive behavior disorders, is a common pitfall, according to the American Academy of Child and Adolescent Psychiatry 7
Confusing manic symptoms with those of ADHD, which can appear similar but represent distinct conditions, is another pitfall, as noted by the American Academy of Child and Adolescent Psychiatry 4, 6
Not recognizing that acute psychosis in an adolescent may be the first presentation of mania, as reported by the American Academy of Child and Adolescent Psychiatry 3
Applying adult diagnostic criteria to children without considering developmental context is also a pitfall, according to the American Academy of Child and Adolescent Psychiatry 7

Depressed, manic, hypomanic, or severely anxious states occurring together are common in mixed presentations, particularly in juvenile presentations and carry increased suicide risk, according to the American Academy of Child and Adolescent Psychiatry 8, 9
The American Academy of Child and Adolescent Psychiatry recommends close monitoring for suicidality, especially in the first months of treatment and following dosage adjustments, as SSRIs carry a boxed warning for suicidal thinking through age 24 10
The pooled absolute rate for suicidal ideation is 1% with antidepressants versus 0.2% with placebo (NNH=143), highlighting the need for careful treatment monitoring, as suggested by the American Academy of Child and Adolescent Psychiatry 10
Behavioral activation/agitation (motor restlessness, insomnia, impulsiveness, disinhibited behavior) is more common in younger children and anxiety disorders, and typically occurs early in SSRI treatment, supporting slow up-titration, according to the American Academy of Child and Adolescent Psychiatry 10
It is essential to distinguish behavioral activation from mania/hypomania, as activation typically occurs in the first month and improves quickly with dose reduction, while mania may appear later and persist despite medication changes, as noted by the American Academy of Child and Adolescent Psychiatry 10

The American Academy of Child and Adolescent Psychiatry notes that behavioral activation from SSRIs should not be confused with hypomania, as the former typically occurs in the first month of treatment and improves quickly with dose reduction, whereas hypomania may appear later and persists despite medication changes, requiring active pharmacological intervention 11

Mood-stabilizing agents and second-generation antipsychotics are effective in treating hypomania, with medications such as lithium, valproate, olanzapine, quetiapine, risperidone, ziprasidone, and aripiprazole being commonly used 11

The American Academy of Child and Adolescent Psychiatry suggests that a history of antidepressant treatment, and subsequent agitation, hyperactivity, or mood elevation, may unmask underlying bipolar disorder 12

A family history of bipolar disorder, depression, or other mood disorders increases the diagnostic likelihood of bipolar disorder, according to the Journal of the American Academy of Child and Adolescent Psychiatry 12
