Emmerdale's Cathy Hope has been the subject of a mental health storyline over the last few weeks and was at the centre of her father Bob's worries when she recently climbed onto a bridge during a manic episode.
The teenager, played by Gabrielle Dowling, finally received answers explaining the possible reason behind her mood sings and manic episodes on Monday night's episode, when her GP suggested it could be premenstrual dysphoric disorder (PMDD). However the teen is still waiting for an official diagnosis.
According to the NHS, Premenstrual dysphoric disorder (PMDD) is a more severe version of premenstrual syndrome (PMS). Most women experience PMS at some point, however women with PMDD will experience the symptoms much more intensely.
