Bipolar disorder is defined as a medical condition in which people have mood swings out of proportion, or seemingly unrelated, to things going on in their lives. These swings affect thoughts, feelings, physical health, behavior, and functioning.

Bipolar disorder is difficult to recognize and diagnose because:

• Bipolar disorder in children and teens does not fit precisely the symptom criteria established for adults - the symptoms can resemble or co-occur with those of other common childhood-onset mental disorders.
• Bipolar disorder may be mistaken for normal emotions and behaviors of children and adolescents.
• Bipolar disorder may be mistaken with symptoms of trauma or abuse.
• Bipolar disorder may be mistaken with symptoms of drug use.
• There is no objective medical test for bipolar disorder.

Bipolar disorder is characterized by recurrent episodes of depression, mania, and/or mixed symptom states. These episodes cause unusual and extreme shifts in mood, energy, and behavior that interfere significantly with normal, healthy functioning.

Manic symptoms include:

• Severe changes in mood - either extremely irritable or overly silly and elated
• Overly-inflated self-esteem; grandiosity
• Increased energy
• Decreased need for sleep - ability to go with very little or no sleep for days without tiring
• Increased talking - talks too much, too fast; changes topics too quickly; cannot be interrupted
• Distractibility - attention moves constantly from one thing to the next
• Hypersexuality - increased sexual thoughts, feelings, or behaviors; use of explicit sexual language
• Increased goal-directed activity or physical agitation
• Disregard of risk - excessive involvement in risky behaviors or activities

• Persistent sad or irritable mood
• Loss of interest in activities once enjoyed
• Significant change in appetite or body weight
• Difficulty sleeping or oversleeping
• Physical agitation or slowing
• Loss of energy
• Feelings of worthlessness or inappropriate guilt
• Difficulty concentrating
• Recurrent thoughts of death or suicide

When depressed, there may be many physical complaints such as headaches, muscle aches, stomachaches or tiredness, frequent absences from school or poor performance in school, talk of or efforts to run away from home, irritability, complaining, unexplained crying, social isolation, poor communication, and extreme sensitivity to rejection or failure.

Other manifestations of manic and depressive states may include alcohol or substance abuse and difficulty with relationships.

Existing evidence indicates that bipolar disorder beginning in childhood or early adolescence may be a different, possibly more severe form of the illness than older adolescent- and adult-onset bipolar disorder.

When the illness begins before or soon after puberty, it is often characterized by a continuous, rapid-cycling, irritable, and mixed symptom state that may co-occur with disruptive behavior disorders, particularly ADHD or conduct disorder (CD), or may have features of these disorders as initial symptoms.

In contrast, later adolescent- or adult-onset bipolar disorder tends to begin suddenly, often with a classic manic episode, and to have a more episodic pattern with relatively stable periods between episodes. There is also less co-occurring ADHD or CD among those with later onset illness.

A child or adolescent who appears to be depressed and exhibits ADHD-like symptoms that are very severe, with excessive temper outbursts and mood changes, should be evaluated by a mental health professional with experience in bipolar disorder, particularly if there is a family history of the illness. This evaluation is especially important since psycho-stimulant medications, often prescribed for ADHD, may worsen manic symptoms. There is also limited evidence suggesting that some of the symptoms of ADHD may be a forerunner of full-blown mania.
