• Premenstrual syndrome is characterised by cyclical physical and behavioural symptoms occurring in the luteal phase of the normal menstrual cycle.
• Premenstrual dysphoric disorder is a more severe variant that includes at least 1 affective symptom. Affective symptoms such as anger, irritability, and/or internal tension occur during the second half of the menstrual cycle, and sometimes extend into the first few days of menses.
• PMS is a diagnosis of exclusion. Physical symptoms are abdominal bloating (most common), breast tenderness, and headaches.
