Premenstrual dysphoric disorder, or PMDD, is a severe form of premenstrual syndrome (PMS). The symptoms of PMDD are similar to those of PMS, but are severe enough to interfere with work, social activities, and relationships.
Different studies have shown a correlation between PMDD and low levels of serotonin, a chemical in the brain that helps transmit nerve signals. Certain brain cells that use serotonin as a messenger are involved in controlling mood, attention, sleep, and pain. Therefore, chronic changes in serotonin levels can lead to PMDD symptoms.
The symptoms of PMDD can include any of the following:
- Mood swings
- Depressed mood or feelings of hopelessness
- Marked anger, increased interpersonal conflicts
- Tension and anxiety
- Irritability
- Decreased interest in usual activities
- Difficulty concentrating
- Fatigue
- Change in appetite
- Feeling out of control or overwhelmed
- Sleep problems
- Physical problems, such as bloating
