How do you tell PMDD from ADHD getting worse before a period?

Telling PMDD from ADHD that gets worse before a period is not something a community thread can do reliably. PMDD is a mood diagnosis with a premenstrual pattern. ADHD is a neurodevelopmental condition whose symptoms can fluctuate across the cycle in some people. FasTreat also offers private online ADHD assessment and ongoing care, depending on your needs and clinical assessment.
