Worrying About Getting Dementia – Is there a Way to Prevent It?

“Insufficient sleep across the lifespan is significantly predictive of your development of Alzheimer's disease pathology in the brain...”

Matthew Walker Ph.D., Newcastle University, Sleep Scientist

Ever wondered, ‘how will I know?’ I feel like I have a poor memory all the time, constantly forgetting where I just put down my phone, where I left my keys, where I put my shoes? And I’m not even middle aged yet. I think this is a fear we all have, losing our memory, sudden dementia, Alzheimer’s, especially when we know someone who’s gone through it, or have heard of someone dealing with their loved one going through it. I find myself obsessively Googling it. And don’t get me wrong, I know dementia is a lot worse than simply forgetting your keys. That in fact, it’s more like having your keys in your hand and not knowing what they’re for, but that doesn’t stop me from obsessively worrying about one day getting it and how I might prevent it.


According to Aging Care, the disease starts out slowly. The symptoms caused from dementia can include anxiety, hallucinations, fear, loneliness, nightmares, and confusion. “One may experience memory problems and forgetfulness.” And a person might’ve had dementia for up to 10 years before being officially diagnosed. But most of all, and what freaks me out the most, is that memory loss CAN be a sign. This is especially true if you:

  • Struggle to remember recent events, although you can easily recall things from the past
  • Find it hard to follow conversations or programmes on TV
  • Forget the names of close friends or everyday objects
  • Struggle to recall things you have heard, seen, or read recently
  • Regularly lose the thread of what you are saying
  • Find yourself putting objects in unusual places – such as your keys in the fridge
  • Feel confused, even in a familiar place, or get lost on familiar journeys
  • Find that people start to notice or comment on your memory, or lack thereof

I mean, I think I can check off at least half the list, although it might just be due to lack of sleep and stress. But then when you go down the Google rabbit hole you start to realize that lack of sleep is a huge factor in the onset of dementia.


A study published in the journal Science Advances last week, found “chronic sleep loss prematurely ages the brain’s immune cells and may lead to cognitive problems, including dementia later in life”. The study also concluded that bad sleep speeds up the aging of brain cells.

“In essence, study participants who had better sleep had ‘younger’ and less activated immune cells and this led to protection ‘against the negative effects of Alzheimer’s disease pathology on cognition…I think it adds one more reason to try and sleep better.” — Dr. Andrew Lim, University of Toronto associate neurology professor.


“I think that sleep may be one of the most significant lifestyle factors that determines your risk ratio for Alzheimer's disease.”

Matthew Walker Ph.D., Newcastle University, Sleep Scientist

According to the Alzheimer’s Association, Alzheimer’s is one of the leading causes of death around the world, at least 44 million people live with dementia, and at this point in time there is no cure. But some studies are measuring the likelihood of one losing their memory versus keeping with the help of quality sleep.

“Getting a good night’s sleep is something we should all do…Our brains need time to recover from the stresses of the day…this and other data suggest that it may even help delay and slow down the disease process if it has begun.” Washington University School of Medicine


When you Google ways to sleep better you’ll most likely come across articles that list the top tips for restful sleep. And they’ll list off things like:

  • Maintain a regular sleep schedule
  • Avoid caffeinated drinks at night
  • Keep the bedroom dark
  • Exercise regularly
  • Avoid screens an hour before bedtime

And they’re all great advice. That said, there’s one tool out there that is designed to help improve sleep and it’s called a Weighted Blanket.

An Important Investment

Sleep: More Protection for your Brain than a Helmet!

I recently got my hands on a Weighted Blanket and I can’t praise it enough. What a game changer! Wrap yourself in one and I swear you’ll find your sleep transformed. It’s like being embraced in a loving hug, a warm and cosy cocoon that puts you to sleep and keeps you asleep until you wake up the next morning a fully formed butterfly ready to take on the day. 

If sleep is the one thing that’s going to keep you quick witted and alert then investing in it and giving a weighted blanket a try seems like a no brainer. I’ve done the Googling for you and made a list of what I think are the top 5 weighted blankets in the UK. Not only are they all a great price, but the top one has a 30 night’s sleep guarantee, which means if you don’t feel like it’s helping you in all the ways it should, you can simply return it.

A Happy Customer Says: “This blanket is brilliant! At first use, it is very heavy and trying to lift it up with your leg whilst in bed is very hard work if you are the kind that likes to ‘stick a leg out’ but after a few days, you get used to the weight. I will say, I sleep much sounder since I purchased this and getting to sleep no longer takes hours just minutes. If you have sleeping problems then this is marvellous!”
