Cyclical Mood Disorder

Meaning

A Cyclical Mood Disorder is a clinical classification characterized by recurrent and predictable episodes of mood disturbance that are temporally linked to specific, often regular, biological or hormonal cycles within the body. In the domain of hormonal health, this term frequently describes conditions like Premenstrual Dysphoric Disorder (PMDD), where severe mood symptoms reliably emerge during the luteal phase of the menstrual cycle and resolve with menses. The core feature is the consistent, rhythmic pattern of symptom onset and remission, indicating an underlying biological trigger.
