Bipolar

Symptoms of bipolar Depression According to the Diagnostic and Statistical manual of arms of cordial Disorders, Fourth Edition (DSM-IV), there are tetrad categories of bipolar distemper: bipolar I, bipolar II, cyclothymia, and bipolar not-otherwise-specified (NOS) (Ford-Martin, 1999). bipolar 1 is characterized by a wild phase, which is usu on the wholey followed by a period of falling off. Depression a lot occurs feature with a manic episode, such as when a patient is depressed, but has locomote thoughts. People with bipolar II put out major depressive episodes vary with periods of hypomania, which is milder than the mania of bipolar I patients. These people tend to feed low energy, mental retardation and mentally retarded physical processes, and control profound fatigue and hypersomnia, an excessive pauperization for sleep. Patients with cyclothymia give way cycling episodes of hypomania and depression, but the depression is not major. These people often develo p bipolar I or bipolar II later in life. fast cycling occurs in roughly 20 percent of bipolar I and bipolar II patients, with manic and depressive episodes cycling at least four quantify a year. Bipolar NOS is a diagnosis for patients who do not fit clearly into either bipolar I, bipolar II or cyclothymia diagnoses.

Bipolar disorder does not call for a clearly delimit cause (Ford-Martin, 1999). As many a(prenominal) as two-thirds of bipolar patients have a family history of affectional or emotional disorders, suggesting a hereditary factor is involved. some(prenominal) studies have shown a genetic function to the disorder. Researchers at Johns Hopkins per! using the inheritance patterns of the disorder believe that unrivaled gene underlies all these conditions (McKinnon et al, 2002). Kelsoe et al (2001) carried out a genome cream off of bipolar disorder patients in a set of 20 families from the North American population. The regions of strongest linkage were found to be 22q and 13q. gene linkage analysis in a further set of 32 families from the same population, which include subjects...If you want to get a full essay, order it on our website: OrderCustomPaper.com
