Alzheimer's disease, as per the National Health Service, UK, is the most common form of dementia. It is a progressive brain disorder that gradually impairs memory, thinking skills and eventually, the ability to perform even simple tasks. This also results in the day-to-day ability of functioning, including finding it difficult to identify a known person, experiencing brain fog, and more. The Kent-born journalist 64 and former GMTV presenter Fiona Phillips who in 2023 announced that she had been diagnosed with early onset dementia thought her husband had kidnapped her because of "delusions", which were one of the symptoms or traits of the Alzheimer's disease. The Independent reports that she was diagnosed with the same in 2022.She Thought It Was MenopauseThe earliest symptoms were brain fog, this is also common in menopausal women, so her initial guess too was menopause when she experienced "brain fog and anxiety". Her husband, Martin Frizell, who is the former This Morning editor, has helped her through her condition and has also helped her write a memoir titled Remember When. The memoir aims to help others who have been diagnosed with the disease. Pain, Anxiety, and Degrading MemoryFrizell, who is 66, shared an update on Phillip's condition on Friday saying that there are times when she does not remember who her husband is. Frizell said that she "doesn't quite know that I'm her husband." He shared the update with This Morning on Friday and said that Fiona sometimes becomes confused about who he is. He further added pointing to a recent photo in the book, "She is looking great and she is kinda smiling...And what you don't know is she thought I'd kidnapped her." However, he did add that she'd recognise him "most of the time."Speaking to ITV, Frizell also said, "She'd love to be here, but she's got anxiety. She's got a kind of secondary problem that causes her to be in pain, a lot, a lot of pain, which adds to the confusion. So it's difficult."He explained that this disease comes with "all sorts of delusions", and that this leaves his wife "kind of worked up". The forgetfulness is such that on some occasions, Phillips asks to go visit her parents, to which, Frizell says, "I have not got the heart to say they aren't here. What you do is, you say, 'Let's get out coats on, let's get out shoes on', we go around the block a couple of times and come back in. And she says, 'Oh I am home now'."What Is Alzheimer's?Alzheimer’s is the leading cause of dementia—a syndrome marked by a continuous decline in brain function, as noted by the NHS.It is a progressive disease that gradually affects memory, thinking, and other cognitive abilities, with symptoms worsening over time.While there is no cure yet, certain medications can help ease some of the symptoms temporarily. To this, Frizell says, "Society has decided we’re not going to take it as seriously as we should. The money that’s there for Alzheimer’s research, it’s like buying a Starbucks cup of coffee, basically trying to fight a disease. It’s impossible.”He also mentioned that early in their relationship, they discussed Phillips granting him lasting power of attorney, so he could make health and financial decisions on her behalf if she ever became unable to do so herself.Last year, in November, he announced that he was stepping down as the editor of This Morning, after a decade in the post, saying that he was expecting "family priorities to change" and needed to free up time for them.
