Bipolar disorder: diagnostic issues.
Summary of "Bipolar disorder: diagnostic issues."
Bipolar disorders are cyclical mood disorders with clinical features including distinct sustained periods of mood elevation. Briefer (4 days or more), mild episodes of mood elevation define bipolar II disorder; lengthier (7 days or more), more severe episodes (or those requiring hospitalisation), with or without psychotic features, define bipolar I disorder. Depressive periods are more common and lengthier than manic or hypomanic states, and are the main cause of disability. Bipolar depression may respond poorly to antidepressants and these medications may destabilise the illness. The diagnosis of bipolar disorder should be considered when a patient with depression is treatment resistant. Irritability is a common symptom in bipolar disorder, particularly during mixed states (during which patients have features of mood elevation and depression concurrently) or when there is rapid cycling of mood (more than four episodes of mood disorder per year). Alcohol misuse and use of illicit drugs may simulate mood changes in bipolar disorder. Accurate diagnosis and assessment of bipolar disorder is essential for clinical decision making and determining prognosis and treatments.

Medical and Biotech [MESH] Definitions
Bipolar Disorder
A major affective disorder marked by severe mood swings (manic or major depressive episodes) and a tendency to remission and recurrence.
Diagnosis, Dual (psychiatry)
The co-existence of a substance abuse disorder with a psychiatric disorder. The diagnostic principle is based on the fact that it has been found often that chemically dependent patients also have psychiatric problems of various degrees of severity.
Lithium
An element in the alkali metals family. It has the atomic symbol Li, atomic number 3, and atomic weight 6.94. Salts of lithium are used in treating BIPOLAR DISORDER.
Retinal Bipolar Cells
INTERNEURONS of the vertebrate RETINA containing two processes. They receive inputs from the RETINAL PHOTORECEPTOR CELLS and send outputs to the RETINAL GANGLION CELLS. The bipolar cells also make lateral connections in the retina with the RETINAL HORIZONTAL CELLS and with the AMACRINE CELLS.
Genetic Counseling
An educational process that provides information and advice to individuals or families about a genetic condition that may affect them. The purpose is to help individuals make informed decisions about marriage, reproduction, and other health management issues based on information about the genetic disease, the available diagnostic tests, and management programs. Psychosocial support is usually offered.
