manic-depressive depression

Bipolar disorder, also called manic-depressive illness, is not as common as major depression or dysthymia.

双相情感障碍，也叫做躁郁症，并不像重度抑郁症或心境恶劣一样普遍。

The so-called dual phase depression, it refers to the patient both manic performance, and depressive symptoms.

所谓双相抑郁，指的是病人既有躁狂表现，又有抑郁症状。

Bipolar disorder (manic depression) may therefore give rise to rages in patients in either the depressive or the overexuberant phases of the disease.

两极性疾病（狂躁型抑郁症）在疾病的抑郁阶段或过度兴奋阶段都可能使病人产生狂怒。
