Actress Maddy Hill, who plays Nancy Carter on Eastenders, has said that she was initially "terrified" about her current epilepsy storyline.
Hill explained: "When I first found out that Nancy had epilepsy, I was absolutely terrified, just because I knew nothing about the illness."
Speaking in a behind-the-scenes video, she added: "I didn't know anyone who had epilepsy and I was very aware of wanting to be respectful to people who suffer with such a massive thing in day-to-day life.
"I imagine - this is something I don't know yet - but I imagine it is going to affect her quite hugely. Look, it's the reason she couldn't go to the army. It holds her back a lot and I can't imagine that not resurfacing."
The charity Epilepsy Action has said that he advised EastEnders on the story and praised the soap for raising awareness of the condition.
