I'm wondering if we can just start by firstly talking about what PMDD is and how it differs from regular

PMS.

So PMDD, premenstrual dysphoric disorder, is actually now included in our DSM, which within the depression disorder category and it's a condition that affects about depending on the literature you read three to eight percent but say about five percent of women where they experience really debilitating symptoms in that premenstrual phase so before they have their period and And the symptoms can vary.

There's a list that you have to follow or look through when you're diagnosing someone.

But one of the key symptoms has to be an emotional symptom.

So it might be mark depression, hopelessness.

It could be irritability.

Okay, so in our small sphere of influence that we can achieve today, what might be useful is, do we know why some women get it and some don't? Are there risk factors we should look for?
