TV presenter Davina McCall feared she was developing Alzheimer's when she started going through the menopause.
The Masked Singer judge, who began perimenopause nine years ago aged 44, said she had always been paranoid about Alzheimer's because her father, Andrew, suffers from it.
McCall went to the doctor with her symptoms, which included memory loss, when they started to affect her busy presenting schedule. She was told her was suffering from "cognitive overload".
The mother-of-three is now having hormone replacement therapy (HRT) to alleviate some of the symptoms.
Speaking on Gabby Logan's podcast The Mid.Point, she said: "I'm on HRT so I have absolutely no excuse to be going doolally but I'm still going doolally on the HRT.
"I am less angry. I don't get night sweats. I don't get hot flushes. These are the things that have gone.
"My joints feel, my bones feel lubricated and strong, but my memory, and like you Gabby, I work, I've got kids, I have a partner.
"Life is very busy and chaotic and you have to know a lot of stuff in your business about sort of everything. And I do lots of different jobs. So I have a hundred different hats on.
"I could be going from Long Lost Family one day, to The Masked Singer the next, to a Garnier job, to something else.
"And I'm learning different things for everything in my brain sometimes, because when I went to my doctor and I said, 'Look, please help me, I think I've got Alzheimer's because obviously my dad's got Alzheimer's'.
"And I was like, 'I'm always paranoid - I know I haven't really got it but am I okay?' to her.
"She said, 'It's called cognitive overload'. And at our stage in life often our kids are all older. We thought it was going to get easier. It does not."
