Phillips who is married to Martin Frizell, editor of ITV’s This Morning told The Mirror that she “long feared” this moment was waiting for her but yet it was still the most “gut-punching, shuddering shock” when a doctor told her the news.

“It’s something I might have thought I’d get at 80 but I was still only 61 years old,” Phillips continued.

“I felt more angry than anything else because this disease has already impacted my life in so many ways; my poor mum was crippled with it, then my dad, my grandparents, my uncle. It just keeps coming back for us.”

Though she has kept the news private for 18 months, Phillips said she had decided to share her story to help end the stigma around Alzheimer’s.

The Strictly Come Dancing star is currently taking part in clinical trials at University College Hospital in London, which aim to revolutionise future treatment.
