Page "Mania" Paragraph 1

In addition to mood disorders, persons may exhibit manic behavior because of drug intoxication ( notably stimulants, such as cocaine and methamphetamine ), medication side effects ( notably steroids and SSRIs ), and malignancy.

But mania is most often associated with bipolar disorder, where episodes of mania may alternate with episodes of major depression.

Gelder, Mayou, and Geddes ( 2005 ) suggest that it is vital that mania be predicted in the early stages because otherwise the patient becomes reluctant to comply to the treatment.

The criteria for bipolar disorder do not include depressive episodes, and the presence of mania in the absence of depressive episodes is sufficient for a diagnosis.

Regardless, those who never experience depression also experience cyclical changes in mood.

These cycles are often affected by changes in sleep cycle ( too much or too little ), diurnal rhythms, and environmental stressors.
