In an upcoming episode of Coronation Street, Kevin Webster, played by Michael Le Vell, watches with concern as his sister Debbie Webster, played by Sue Devaney, deteriorates. Debbie was diagnosed with vascular dementia in early 2025, after noticing worrying symptoms such as forgetfulness, misplacing personal items, and making mistakes at work. Additionally, she experienced mood swings and blackouts, one of which resulted in a fall.

The doctor explained that the blackouts could have been a TIA or mini-stroke and sent her for more tests, including a memory clinic. Actress Sue Devaney will continue to play Debbie until at least 2027, which indicates that the ITV soap will continue to show the impact of dementia on the character's life for several more months.

At the beginning of 2026, Debbie's world was turned upside down when she was arrested for drunk driving, although it wasn't actually her fault. Her son, Carl Webster, played by Jonathan Howard, was the one driving and caused an accident. Debbie took the blame to protect her son, which led to her imprisonment. She has been incarcerated ever since and receives support from Lou Michaelis, a former Weatherfield resident.

In a new video, Debbie arrives in the visiting room to see Kevin and Jack Webster, played by Kyran Bowes. Ronnie and Kevin now know the truth about Debbie and Carl.

In the visiting room, Debbie talks about her attempt to knit a sweater for Carl, and Kevin mentions the possibility of her returning home soon. While talking about the skills she has learned, Debbie tries to open a carton of drink, but gets confused and doesn't realize she needs to use a straw to access the juice. Jack helps her, but Kevin watches with sadness, aware that it's another sign of Debbie's declining health.

This preview offers a touching look at Debbie's struggle with vascular dementia and how this disease affects her daily life and relationships. The series continues to explore the complexities of this condition and its effects on the character and her environment.
