BIPOLAR DISORDER DIAGNOSIS |
||
|
Bipolar disorder is usually diagnosed
and treated by a psychiatrist and/or a psychologist with medical
assistance. In addition to an interview, 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 Millon Clinical Multiaxial Inventory III (MCMI-III), Minnesota
Multiphasic Personality Inventory II (MMPI-2), the Internal State
Scale (ISS), the Self-Report Manic Inventory (SRMI), and the Young
Mania Rating Scale (YMRS). The tests are verbal and/or written and
are administered in both hospital and outpatient settings. Psychologists and psychiatrists typically use the criteria listed in the Diagnostic and Statistical Manual of Mental Disorders, Fourth Edition (DSM-IV) as a guideline for diagnosis of bipolar disorder and other mental illnesses. DSM-IV describes a manic episode as an abnormally elevated or irritable mood lasting a period of at least one week that is distinguished by at least three of the mania symptoms: inflated self-esteem, decreased need for sleep, talkativeness, racing thoughts, distractibility, increase in goal-directed activity, or excessive involvement in pleasurable activities that have a high potential for painful consequences. If the mood of the patient is irritable and not elevated, four of the symptoms are required. Although many clinicians find the criteria too rigid, a hypomanic diagnosis requires a duration of at least four days with at least three of the symptoms indicated for manic episodes (four if mood is irritable and not elevated). DSM-IV notes that unlike manic episodes, hypomanic episodes do not cause a marked impairment in social or occupational functioning, do not require hospitalization, and do not have psychotic features. In addition, because hypomanic episodes are characterized by high energy and goal directed activities and often result in a positive outcome, or are perceived in a positive manner by the patient, bipolar II disorder can go undiagnosed. 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 toward irritability and aggressiveness instead of elation. 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). Furthermore, their aggression often leads to violence, which may be misdiagnosed as a conduct disorder. Substance abuse, thyroid disease, and use of prescription or over-the-counter medication can mask or mimic the presence of bipolar disorder. In cases of substance abuse, the patient must ordinarily undergo a period of detoxification and abstinence before a mood disorder is diagnosed and treatment begins. |
