Bipolar disorder in children
Encyclopedia
Bipolar Disorder formerly known as "Manic Depression", is characterized by extreme changes in mood that range from depressive "lows" to manic "highs" (typified by feelings of excessive happiness or rage). It is important to note that these moods exceed normal responses to life events, represent a change from the individual's normal functioning, and cause problems in daily activities --- for instance, in getting along with family, friends and teachers, or in completing schoolwork.

Depressive symptoms of BPD often include sadness, irritability, an inability to enjoy one's usual activities, changes in appetite or weight, and/or sleeping more than normal or having difficulty falling/staying asleep even when tired.

Manic symptoms of BPD may include the following: inflated or unrealistic self-esteem; needing less sleep than normal and still feeling energetic; talking more/faster than normal; changing the topic of conversation so quickly/often that it interferes with communication; feeling that one's thoughts are "racing"; increased distractibility; difficulty sitting still; an unusual drive to engage in activities or pursue goals (e.g., excessive cleaning, making clearly unrealistic plans); and engaging in risky or dangerous behaviors (e.g., riding a bike on the highway; inappropriate sexual behaviors).

Identifying BPD in youth is challenging. While adults with BPD often have distinct periods of depression and mania that last for weeks, months, or longer, youth with BPD frequently have depressive and manic symptoms that occur daily, sometimes even simultaneously. As co-occurring disorders are common, determining what symptoms are signs of BPD and which are due to other disorders (e.g., depression, ADHD, disruptive behavior problems) is critical.

Diagnosis of bipolar disorder in children is controversial. While some believe the DSM-IV criteria should be followed others have proposed other behavioral markers specific for children BD. Another origin for controversy is the rise in the number of diagnosis in the last years, specially in the USA, with several possible causes for this increase. When following DSM criteria prevalence of BD in children is around 2% of the population

 and cognitive behavioral therapy. Both kind of treatments are in many cases chronic.

Cases of BD in children have been known for long, although they were thought to be rare. This view changed in the last part of the twentieth century. Future research directions include improving treatments, diagnostic criteria and the knowledge of BD in children.

Signs and symptoms

Pediatric bipolar disorder (PBD) causes a significant impairment in the ability of children to function normally, especially in academics and psychosocial areas, and it is a chronic disorder that persists throughout the lifetime. Children with PBD experience chronic periods of mania, characterized by elevated and irritable moods, or depression. PBD patients are ten times more likely to commit suicide

 than healthy children. Severe manic and depressive symptoms are associated with early age of diagnosis, meaning children often display more acute symptoms than adults. In children, mania often presents with psychotic symptoms and mixed manic depressive episodes. Such a presentation of mania often differs from classic descriptions of mania in adults, yet children who are diagnosed with bipolar disorder show the same brain abnormalities as adults, further complicating diagnosis. Children with PBD display anger, dysphoria, irritability, belligerence, and mixed-manic depressive symptoms more commonly and for more erratic time periods than adults.

Diagnosis

The diagnosis of childhood BD is controversial, although it is not under discussion that BD typical symptoms are dysfunctional and have negative consequences for minors suffering them. Main discussion is centered on whether what is called BD in children refers to the same disorder than when diagnosing adults, and the related question on whether adults criteria for diagnosis are useful and accurate when applied to children. More specifically main discussion over diagnosis in children circles around mania symptomatology and its differences between children and adults. For the diagnosis of mania the American Psychiatric Association

's Diagnostic and Statistical Manual (DSM-IV-TR) requires a "distinct period of abnormally and persistently elevated, expansive or irritable mood" during at least four days, and a number of extra behavioral and cognitive symptoms such as grandiosity, reduced sleep need and risk seeking behaviors. Regarding diagnosis of children some experts recommend to follow the same DSM criteria than for adults, although taking into account the age of the individual and the normal behavior of those of his age. Others believe that these criteria do not separate correctly children with BD from other problems such as ADHD, and emphasize fast mood cycles. Still others argue that what accurately differentiates children with BD is the distinct irritability with which it courses.

 encourage the first strategy.

Increase

Number of American children and adolescents diagnosed of BD in community hospitals increased 4-fold reaching rates of up to 40% in 10 years around the beginning of the current century, while in outpatient clinics it doubled reaching the 6%. Outpatient office visits for children and adolescents with bipolar disorder in the United States increased from 20,000 in 1994–95 to 800,000 in 2002–03. The data suggest that doctors

 has increased.

The reasons for this increase in diagnosis are unclear. On the one hand, the recent consensus from the scientific community (see above) will have educated clinicians about the nature of the disorder and the methods for diagnosis and treatment in children. That, in turn, should increase the rate of diagnosis. On the other hand, assumptions regarding behavior, particularly in regard to the differential diagnosis of bipolar disorder, ADHD, and conduct disorder in children and adolescents, may also play a role. In addition, some argue that the rise in diagnosis of pediatric bipolar disorder is the result of the influence of the pharmaceutical industry on psychiatry, especially with regard to big pharma's recent push to expand the market of atypical antipsychotics to children and the elderly.

National differences

Another factor is that the "consensus" regarding the diagnosis in the pediatric age group seems to apply only to the USA. The British National Institute on Health and Clinical Excellence (NICE) guidelines on bipolar disorder in 2006 specifically described the broadened criteria used in the USA to diagnose bipolar disorder in children as suitable "only for research" and "were not convinced that evidence currently exists to support the everyday clinical use of (pediatric bipolar phenotype) diagnoses" which increase the "risk that medicines may be used to inappropriately treat a bipolar diathesis that does not exist."(p526). A 2002 German survey of 251 child and adolescent psychiatrists (average 15 years clinical experience) found only 8% had ever diagnosed a pre-pubertal case of bipolar disorder in their careers. A similar survey of 199 child & adolescent psychiatrists (av 15 years clinical experience) in Australia and New Zealand also found much lower rates of diagnosis than in the USA and a consensus that bipolar disorder was overdiagnosed in children and youth in the USA. Concerns about overdiagnosis in the USA have also been expressed by American child & adolescent psychiatrists and a series of essays in the book "Bipolar children: Cutting-edge controversy, insights and research" highlight several controversies and suggest the science still lacks consensus with regard to bipolar disorder diagnosis in the pediatric age group.

Epidemiology

Studies using DSM criteria show that up to 2% of youth may have bipolar disorder.

Studies in clinics using these criteria show that up to 20% of youth referred to psychiatric clinics have bipolar disorder.

Treatment

Usual treatment involves medication and psychotherapy. Nevertheless studies on the treatment of BD in children are scarce and of low quality, and many times approaches are directly derived from studies and practice with adults.

Drug prescription is commonly used as the initial treatment. It aims to reduce symptomatology and maximize the positive effect of psychotherapeutic interventions that may come afterwards. It usually consists in mood stabilizer

 as a critical tool. Finally cognitive-behavioral training is directed towards the participants having a better understanding and control over their emotions and behaviors.

Family therapy has strong support for treatment of pediatric bipolar disorder. Family Therapy is a branch of psychotherapy that works with families. It tends to view change in terms of the systems of interactions between family members. Families are seen as an interconnected force where the actions of the family members affect the health or dysfunction of each individual and the family as a whole. Family therapists focus on relationship patterns and are generally more interested in what goes on between family members rather than within one or more individuals. One family member may have a problem and the family relationships may be contributing to or maintaining that problem. For example, when a child has a behavior problem, family therapists may see the child as a 'scapegoat' and view the problem as actually residing within the family system. Family therapists avoid blaming any family member for the problem, and instead help the family interact in different ways that may solve the problem. There are both general, historical models of Family therapy (i.e., Structural, Strategic, Bowenian) and more specific, evidence-based approaches that are based on the earlier models. Strong research evidence suggests that both general and specific family therapy approaches are effective with a wide variety of clinical problems, including the treatment of bipolar spectrum disorders.

Cognitive behavioral therapy (CBT) is also effective in treating bipolar disorder in young people. CBT is the term used for a group of psychological treatments that are based on scientific evidence. These treatments have been proven to be effective in treating many psychological disorders among children and adolescents, as well as adults.

In general BD in children was not recognized in the first half of the XX century with first reviews of cases being published in the 60s. True recognition came twenty years after, with epidemiological studies showing that in approximately 20% of adults with BD already had symptoms in childhood or adolescence. Nevertheless onset before age 10 was thought to be rare, below 0.5% of the cases. During the second half of the century misdiagnosis with schizophrenia

Research directions

Current research directions for BD in children include optimizing treatments for this population through well designed clinical trials, increasing the knowledge of the genetic and neurobiological basis of the pediatric disorder, finding out why so many pediatric cases are among boys whereas many adult cases are in women, and improving diagnostic criteria. Regarding the latter the mental health professionals charged with forming the new Diagnostic and Statistical Manual for Mental Disorders (the DSM-V) have proposed a new diagnosis, Disruptive Mood Dysregulation Disorder, which (though it is still a biologically based mental illness requiring drug and psychotherapeutic treatment) is considered to cover some presentations involving behavioral outbursts in different settings and locations that is as of now currently thought of as simple childhood-onset bipolar disorder occurring before puberty.
