For some women, the days before their period bring much more than the usual symptoms of PMS.

Premenstrual dysphoric disorder, or PMDD, can cause severe changes in mood, anxiety, irritability, fatigue and concentration — disrupting work, relationships and everyday life.

Francesca Rudkin and Louise Ayrey are joined by clinical neuropsychologist Dr Caroline Gurvich to explain what PMDD is, why some women may be particularly sensitive to hormonal changes, its links with ADHD and perimenopause, and how it can be diagnosed and treated.

Plus, why tracking your symptoms could be the first step towards recognising that something more than PMS is going on.
