Bipolar Disorder

According to the American Academy of Child and Adolescent Psychiatry, up to one third of American children and adolescents diagnosed with depression develop early onset bipolar disorder. The average age of onset of bipolar disorder is from adolescence through the early twenties. However, because of the complexity of the disorder, a correct diagnosis can be delayed for several years or more. In a survey of bipolar patients conducted by the National Depressive and Manic Depressive Association (MDMDA), one half of respondents reported visiting three or more professionals before receiving a correct diagnosis, and over one third reported waiting ten years or more before they were correctly diagnosed.

When symptoms of bipolar disorder are present, a child should be taken to a qualified medical healthcare professional as soon as possible for evaluation. If a child or teen diagnosed with bipolar disorder reveals at any time that they have had recent thoughts of self-injury or suicide, or if they demonstrate behavior that compromises their safety or the safety of others, professional assistance from a mental healthcare provider or care facility should be sought immediately.

Bipolar disorder usually is diagnosed and treated by a psychiatrist and/or a psychologist. In addition to an interview with the child and her parents, several clinical inventories or scales may be used to assess the patient’s mental status and determine the presence of bipolar symptoms. These include the Children’s Global Assessment Scale (C-GAS), General Behavior Inventory (GBI), Beck Depression Inventory (BDI), Minnesota Multiphasic Personality Inventory Adolescent (MMPI-A), the Youth Inventory (YI-4), and the Young Mania Rating Scale (YMRS). The tests are verbal and/or written and are administered in both hospital and outpatient settings.

Bipolar symptoms often present differently in children and adolescents. Manic episodes in these age groups are typically characterized by more psychotic features than in adults, which may lead to a misdiagnosis of schizophrenia. Children and adolescents also tend to demonstrate irritability and aggressiveness instead of the elation of mania in adults. Further, symptoms tend to be chronic, or ongoing, rather than acute, or episodic. Bipolar children are easily distracted, impulsive, and hyperactive, which can lead to a misdiagnosis of attention deficit hyperactivity disorder (ADHD). Their aggression can lead to violence, which may be misdiagnosed as a conduct disorder.

Substance abuse can mask or mimic the presence of bipolar disorder and can make diagnosis more difficult in adolescents. When substance abuse or addiction is present, a patient must ordinarily undergo a period of detoxification and abstinence before a mood disorder can be accurately diagnosed.

Because bipolar disorder is thought to be biological in nature, therapy and/or counseling is recommended as a companion to, but not a substitute for, pharmaceutical treatment of the disease. Psychotherapy, such as cognitive-behavioral therapy, can be a useful tool in helping patients and their families adjust to the disorder, in encouraging compliance to a medication regimen, and in reducing the risk of suicide. A 2003 report revealed that people on medication for bipolar disorder had better results if they also participated in family-focused therapy.

While most children show some positive response to treatment, response varies widely, from full recovery to a complete lack of response to all drug and/or ECT therapy. Drug therapies frequently need adjustment to achieve the maximum benefit for the patient. Bipolar disorder is a chronic recurrent illness in over 90 percent of those afflicted, and one that requires lifelong observation and treatment after diagnosis. Patients with untreated or inadequately treated bipolar disorder have a suicide rate of 15 to 25 percent and a nine-year decrease in life expectancy. With proper treatment, the life expectancy of the bipolar patient will increase by nearly seven years and work productivity increases by 10 years.

According to the American Psychiatric Association, bipolar children and adolescents experiencing a manic episode have a one-year recovery rate of 37.1 percent and a relapse rate of 38.3 percent. Discontinuing lithium treatment too early may increase the risk of relapse in adolescents with bipolar disorder. In one 1990 study, 92 percent of adolescents hospitalized for mania who stopped taking the drug experienced a relapse of symptoms within 18 months of discharge, compared to 37 percent of those who stayed on lithium therapy.

Children and teens with bipolar disorder are at a greater risk for substance abuse than their non-bipolar peers, and substance abuse can worsen or complicate bipolar treatment. In a 1999 two-year follow-up study of adolescents hospitalized for manic episodes, patients who had ongoing drug or alcohol abuse problems had more manic episodes and poorer functioning than those patients who were not substance abusers. In addition, some studies have indicated that children who develop bipolar disorder in adolescence are more likely to develop a substance abuse problem than those who have early-onset of bipolar disorder in childhood.
