Premenstrual Syndrome (PMS) and Premenstrual Dysphoric Disorder (PMDD)

摘要

Levels of brain chemicals called neurotransmitters, such as serontonin, may also play a part in causing PMS. Recent research shows that some women inherit a gene that raises their risk for PMDD. Other possible causes are undiagnosed depression and anxiety problems. If a woman has symptoms that don’t stop shortly after her period starts, she may have another condition, such as depression.
