The Origin of PMDD vs PMS

PMS was first described in medical texts in the early 20th century. It comes from:

• Pre (before)
  
• Menstrual (period)
  
• Syndrome (group of symptoms)
  

PMDD is a newer term. It was officially recognized by medical bodies in the 1990s.

• Dysphoric means deep sadness or distress.
  

The difference exists because doctors needed a separate name for severe emotional symptoms that were not “normal PMS.”
