Bipolar disorder more common than expected in hospitalized adolescents

29.12.2005


One in five teens needing inpatient psychiatric care may be manic-depressive



Clinicians at Bradley Hospital, the nation’s first psychiatric hospital for children and adolescents, have found that bipolar disorder is more common than expected in teens in a psychiatric inpatient setting.

"In the past, mental health professionals thought that about one percent of teens was bipolar – our research indicates that if a strict definition of the illness is applied, up to twenty percent of adolescents on psychiatric units may be manic-depressive," says lead author Jeffrey Hunt, MD, a child psychiatrist at Bradley Hospital and clinical assistant professor of psychiatry at Brown Medical School. The study appears in the December issue of the Journal of Child and Adolescent Psychopharmacology.


Bipolar disorder, also known as manic depression, is characterized by dramatic mood swings – from overly "high" and/or irritable to sad and hopeless, and then back again. "There are often periods of normal mood in between, but there is always accompanying serious impairment in functioning," says Hunt.

This disorder was once believed to be rare in children and adolescents, but because of controversies surrounding diagnosis in juveniles, and because few large-scale studies have been conducted, prevalence rates of bipolar disorder in clinical and community samples of children and adolescents remain difficult to determine, the authors write.

The authors say that screening patients for manic symptoms upon admittance to a psychiatric unit can ultimately lead to better treatment overall. For example, many psychiatric patients first present with symptoms of depression, but depression can also be an indicator of bipolar disorder. The danger lies in the fact that the medication for treating depression can actually have an adverse effect on someone with manic-depression.

"This research is important because diagnosis of juvenile bipolar disorder is controversial – impulsivity, irritability and hyperactivity commonly occur in adolescents in general. If these symptoms all present concurrently, the challenge is to determine whether they are symptoms of bipolar disorder, or are simply a normal part of teenage development," says Hunt.

The authors assessed a total of 391 consecutive admissions to the psychiatric inpatient unit at Bradley Hospital using a mania rating scale derived from a well-known research interview called the K-SADS (the Kiddie Schedule for Affective Disorders and Schizophrenia) as well as other history from both parents and adolescents. They found that manic symptoms such as severe irritability, impulsivity, depression, and hypersexuality are frequently found in hospitalized adolescents. Twenty percent of these patients were diagnosed with juvenile bipolar disorder when information from all sources was integrated with the scores from the K-SADS mania rating scale.

This study is the first to apply the K-SADS mania rating scale with patients "off the street" (i.e., not selected for the study). The authors screened all adolescent admissions to Bradley Hospital regardless if they had a history of mania. Prior research studies using this scale on bipolar prevalence rates only looked at previously diagnosed patients.

The authors found that, compared to patients admitted for depression alone, bipolar patients were more suicidal and aggressive, consequently needing higher levels of care. In addition, over half of the patients diagnosed with juvenile bipolar disorder were admitted during a depressive episode.

"So you might not be able to tease out the difference between a manic-depressive episode and depression unless you can accurately test for bipolar disorder," says Hunt. "We found that the K-SADS was an effective way to as accurately as possible diagnose bipolar disorder, and to help prevent treating bipolar patients presenting in a depressed phase with antidepressants," Hunt states.

According to the National Institute of Mental Health (NIMH), bipolar disorder typically develops in late adolescence or early adulthood. However, some people have their first symptoms during childhood, and some develop them late in life. It is often not recognized as an illness, and people may suffer for years before it is properly diagnosed and treated.

Im Focus: Fizzy soda water could be key to clean manufacture of flat wonder material: Graphene

Whether you call it effervescent, fizzy, or sparkling, carbonated water is making a comeback as a beverage. Aside from quenching thirst, researchers at the University of Illinois at Urbana-Champaign have discovered a new use for these "bubbly" concoctions that will have major impact on the manufacturer of the world's thinnest, flattest, and one most useful materials -- graphene.

As graphene's popularity grows as an advanced "wonder" material, the speed and quality at which it can be manufactured will be paramount. With that in mind,...

Im Focus: Exotic quantum states made from light: Physicists create optical “wells” for a super-photon

Physicists at the University of Bonn have managed to create optical hollows and more complex patterns into which the light of a Bose-Einstein condensate flows. The creation of such highly low-loss structures for light is a prerequisite for complex light circuits, such as for quantum information processing for a new generation of computers. The researchers are now presenting their results in the journal Nature Photonics.

Light particles (photons) occur as tiny, indivisible portions. Many thousands of these light portions can be merged to form a single super-photon if they are...

Im Focus: Circular RNA linked to brain function

For the first time, scientists have shown that circular RNA is linked to brain function. When a RNA molecule called Cdr1as was deleted from the genome of mice, the animals had problems filtering out unnecessary information – like patients suffering from neuropsychiatric disorders.

While hundreds of circular RNAs (circRNAs) are abundant in mammalian brains, one big question has remained unanswered: What are they actually good for? In the...

Im Focus: Scientists shine new light on the “other high temperature superconductor”

A study led by scientists of the Max Planck Institute for the Structure and Dynamics of Matter (MPSD) at the Center for Free-Electron Laser Science in Hamburg presents evidence of the coexistence of superconductivity and “charge-density-waves” in compounds of the poorly-studied family of bismuthates. This observation opens up new perspectives for a deeper understanding of the phenomenon of high-temperature superconductivity, a topic which is at the core of condensed matter research since more than 30 years. The paper by Nicoletti et al has been published in the PNAS.

Since the beginning of the 20th century, superconductivity had been observed in some metals at temperatures only a few degrees above the absolute zero (minus...
