5 New Year’s resolutions to help reduce your risk of dementia

Here are five things you can do to help lower your chances of developing dementia, with illustrations by multi-award winning cartoonist, the late Tony Husband.

Like many people, you may have made some resolutions for the New Year. Perhaps you’re determined to improve your health by doing more exercise or drinking less alcohol.

Making healthier choices can help reduce your risk of dementia. While some things that affect your risk of dementia can’t be changed, such as your age or genes, there are many things you can change.

Here are just five of the things you can do to help lower your risk of dementia. They relevant to everyone but are especially important if you’re in your 40s, 50s or 60s.

1. Get moving

One of the best ways to reduce your risk of dementia is being physically active several times each week.

This helps to keep you healthy in so many ways, including looking after the blood vessels in your brain so they’re able to keep supplying it with the oxygen and nutrients it needs to work properly.

Physical activity is also good for your mental health and helps you to sleep better.

Try to do a combination of activities you’ll enjoy, as you’re more likely to stick to them, such as:

  • activities that get you moving and breathing faster, such as brisk walking, swimming, pilates, or riding a bike
  • activities that strengthen your muscles, such as digging and shovelling in the garden, dancing, climbing stairs, or lifting weights.

Older people who are at risk of falling may find exercises that strengthen their legs help them to stay steadier on their feet. It can also help to reduce joint pain.

Watch your diet

2. Eat well

A healthy, balanced diet is likely to reduce your risk of dementia, as well as several other health conditions including cancer, diabetes, stroke and heart disease.

Top tips for healthy eating include eating:

  • wholegrain foods in most meals, such as wholemeal bread, rice and pasta
  • lots of fruits, vegetables, pulses (beans, peas, lentils), nuts and seeds
  • at least two portions of fish each week, including an oily fish such as salmon, sardines or mackerel.
  • lower-fat dairy foods
  • less red or processed meat
  • only having sugary foods, such as biscuits, cakes or chocolate, as occasional treats
  • less salt – no more than about a teaspoon (6g) each day.

The Eatwell Guide from the NHS shows how much of what we eat overall should come from each food group to achieve a healthy, balanced diet.

3. Quit smoking and cut down on alcohol

If you smoke, you’re putting yourself at much higher risk of developing dementia later in life, as well as other conditions such as cancer, heart disease and stroke.

Drinking too much alcohol also increases your risk of developing dementia.

Aim to drink no more than 14 units per week, which is equivalent to about 7 pints of lower-strength beer or lager, and don’t drink more than 6 to 8 units at a time.

Don't Smoke

4. Keep your mind active

Engaging in mental or social activities may help to build up your brain’s ability to cope with disease, relieve stress and improve your mood. Find an activity you enjoy, as you’re more likely to keep it up.

For example:

  • any kind of adult education or learning
  • arts and crafts (especially in groups)
  • playing a musical instrument or singing
  • volunteering
  • reading books or magazines, or becoming a member of a book club
  • doing brainteasers, such as puzzles, crosswords or quizzes
  • playing card games or board games
  • learning a new language
  • creative writing – such as stories, articles or blogs – or just keeping a diary.

You might want to do some of these activities with friends or neighbours. Spending time with other people helps to keep your mind active.

Look after your health cartoon

5. Look after your health

Taking control of your health will help reduce your risk of dementia. If you’re aged 40–74, start by getting your free NHS health check:

  • In England, you’ll be invited to this by your GP every five years, unless you have a pre-existing health condition.
  • In Wales, you can use the ‘Add to Your Life’ free online health and wellbeing check.
  • In Northern Ireland, you can book a Well Check via Northern Ireland Chest, Heart and Stroke (NICHS).

It’s also important to protect your head from injuries by wearing protective headgear where there is a higher-than-normal risk of head injury – for example, riding a bike, working on a building site, horse-riding, playing cricket -– and definitely if skateboarding!

Get support from your GP if you are having trouble with hearing loss, if you aren’t getting enough sleep, or if you think you may be depressed. Each of these has been shown to increase risk of dementia.

My 83 years old husband has been in a care home for 3 months now and I miss him terribly after 59 years of marriage. He has no quality of life, he cannot hold a conversation or even answer a simple question about what he had for lunch. So cruel and sad.

I also feel upset when I see advice in the newspaper or elsewhere on "preventing" dementia. My husband, now almost 93, was a highly qualified research chemist with several patents to his name. He played tennis until he was almost 90, rode his bike most days until an accident put paid to that, and still walks for at least half an hour most days. We have always been careful about our diet until recently when I have had to use more pre-prepared foods because of my own disabilities and eat plenty of fruit and veg. He never smoked and drank alcohol moderately. He kept very active mentally . In spite of all this he developed dementia - first showing signs about four years ago and diagnosed over two years ago. Now he has difficulty in understanding simple instructions, can't use even the most basic mobile phone and finds newspapers and TV unintelligible . It is heart-breaking so don't tell me it could have been prevented.

All I can say to all people with dementia if you have a bucket list do it sooner than later My wide pat is now in the final stage of Alzheimer’s we did it while she understood what it was all about and I am glad we did as now pat understands nothing

I believe all mental and physical activities can improve our capabilities and motivation; we need to consider our options and go for it, even if we only have limited time to do this!
Good luck everyone.

My Mum is 80. She has Altzheimers. It is galloping along. Every week I try to appreciate what we can enjoy together, what makes her laugh, sing or smile. I'm lucky, she has carers.
To people with early stage memory issues.... Please, get your financial affairs and Power of Atterney for £ plus the one for your welfare. Treat your family fairly and carefully to prevent problems later on.

Well, you were doing okay until you suggested we base our diet around bread, pasta and potatoes. Absolutely the very worst things. Back to the drawing board with you. other than that, not bad. Keep up the good work.

I am not in England, Wales or any part of the UK. I am in New York City.

An interesting variation of Dementia experiences, almost daunting (I might add, the human toll of sadness and relationships both from partnerships and memory loss). I must be rare in all this. Three years ago after an MRI scan and crippling headaches I was told Mr (S) the result of the scan shows evidence of Amyloids and tangled sets of,protein matter", on the brain.My Doctor, seemed uncomfortable to say the word,"Symptoms of early Alzhiemers Disease"ever since i decided to up my game, I walk , dance ,read, improved my culinary skills, attend exercise classes, preparing the swimming,contacted my Alumni at two universities, planning to join setting up a 'health care project in Te Gambia with like minded person' I don's sleep well at nights but I sleep when I can,I love a good glass of brandy and sometimes an Australian Merleau.I have a large family of children and grand children also great grandchildren My deepest love is reading non fiction and the study of all the subjects of the Humanities,My last purchase is a text book entitled "The Archeology of the Mind" I do not recommend this for everyday reading as it is for professionals with an understanding of and interest in neuro-scientific issues.I retired when I was 65, and kept going since , in December of 2020 I would have reached my 90th birthday I live alone love my company and some gardening when the weather permits. By the way am a member of (QRD) quality research in Dementia ,I plan writing a project plan to apply for funding to complete a Master's degree that I started etc etc... wish me luck.

I agree with all the sentiments that the above have written. Please put a stop to this stigmatisation of people with Alzheimer’s. It is so cruel and hurtful to hear this untrue mantra publicised by the popular press on a daily basis. It feels like a blame game. My husband led a full, healthy and active lifestyle, eating healthy and nutritious food. He held a professional career and went on to third level education.The only medication he is taking is Donepezil. He has had memory problems since he turned 70 and was diagnosed when he was 73. We as Carers need encouragement, not blame.

I was informed officially in september1918, but the first positive sign was about 13 years ago (with hardening arteries in the brain) a few years later it was (mild degenerative vascular disease). SO ITS TAKEN A LONG TIME TO REACH TODAY.IWAKE MOST MORNINGS AND CAN NOT REMEMBER WHAT DAY IT IS,i ask myself what did I do yesterday, I get the correct answer on getting up and looking at the calendar, the TV times, the BBC televisions news. I am now fully aware. why I am writing today is: I had a little sleep in my armchair this afternoon, when I woke, I will be late for work (I worked nights before retiring) it took a LONG few minutes or lots of seconds to think where is work, I decided I retired about 12 years ago, COULD THIS LATEST EVENT MEAN AM I THAT MUCH NEARER , THAN NOT BEING AWARE OF MY OWN FAMILY AND FRIENDS. I MUST ADD I HAVE THREE ADULT CHILDREN and THREE LOVELY GRAND CHILDREN THAT I LOVE DEARLY, AND SEE REGULARLY, ANDMY THREE ADULT CHILDREN ATE JUST A PHONE CALL AWAY or is it EITHER OF THEM THATS AT MY FRONT DOOR, LIFE COULD ONLY BE MUCH WORST WITH OUT FAMILY AND FRIENDS. I wrote the above after reading other comments above, TODAY, I CAN NOT IN MY HEART COMPLAIN ABOUT WHAT IS SLOWLY HAPPENING. IF MY MESSAGE HELPS IN ANY WAY TO OTHERS THAT WILL BE SO VERY PLEASING. LASTLY, THE HELP FROM THE STAFF AT N.H.S.,I HOPE THATS THE LAST THING I FORGET. THANK YOU DAVID W. GARNHAM.

Appreciate the advice given on the 5 things to reduce risk of dementia. My mother did all these things, worked till she was 74, ate little but healthy, a tea total-er, sociable and yet she lived with Alzheimer for 15 years- it destroyed her personality, her humour and everything. Is it not a known fact that Alzheimer/dementia is genetic? Whilst the 5 things may or may not help, should the organization be misleading the public? Sorry, if this sounds harsh.

Hi Nina, I'm very sorry to hear about your mother. Our advice here is about reducing the risk of dementia rather than preventing it completely. There are some risk factors that of course can't be avoided. You can read more of our advice on our 'Risk factors and prevention' pages here: https://www.alzheimers.org.uk/about-dementia/risk-factors-and-prevention

Thank you,

I have had a DNA health check on 23andme and fortunately I do not carry the Alzheimer gene. Many people would prefer not to know Nina but you are certainly able to find out your genetic pre-dispositions.
Had it shown I carried the gene then I would immediately have rearranged my life based on the high probability that Alzheimers would eventually catch up with me.

Shocking that as a carer 80 years old I am not offered a regular health check. Surgery says this is an NHS stipulation but I can book in to see a doctor if I have something wrong.

When my husband was still at home, before going into a care home a couple of years ago, the district nurse would come and check his blood pressure, etc. I said to her then, why don't carers get checked out, they are doing a stressful job and she agreed it was important but that they don't do that.

This is my thoughts exactly also Maggie. My dad died of mixed dementia in 2018, he watched what he eat and didn't smoke or drink. He was always fit and was always slim throughout his life.

My wonderful husband was diagnosed with Vascular Dementia 16 years ago. I have just read your advice in reducing the risk. So he has cycled since he was about 5. When I first met him he was doing 30 miles a day to and from work. Saturday doing his Mums shopping by cycle. Sunday lots of miles with cycle club. He continued like that. When he retired age 62 he was out on his bike every day. Two days a week with clubs., the last time he got lost Aged 84. I had to stop it but put his bike on turbo trainer in front room and walked him a lot. So I think that sorts the exercise. We have always eaten healthily all made from Scratch by me. Even jam from fruit in garden. He was always about 9sr 8ozs. That should sort nutrition. He gave up smoking over 50/ years ago. . That is that one sorted. He never drank very much. Even no w his blood pressure and heart are good. Couple of pints of ale a week. So I get fed up with reading in newspapers and magazines how to help prevent dementia. There must be a lot more to it!!

I think keeping fit and healthy is important generally. Common sense tells us keeping asnfit and healthy as we can is helpful. But not singles out as part of preventing Alzheimer's. I feel these sort of messages undermine the desease and make others, not involved and living it, think it is self inflicted and due to lifestyle choices. Which is not so. It's hard enough to live with without this sort of thing saying lifestyle is the cause.
If the cause is unknown how can our lifestyle prevent it!

Totally agree Maggie. My husband died on 30 December at the age of 69 having lived with Alzheimer’s for 15 years. He ticked all of the 5 boxes above. Living healthily is common sense for all sorts of reasons. But these messages give the idea that people with dementia have in some way brought it on themselves through poor life style choices.

Hi Maggie, thank you for your comment. You are correct, keeping fit is important generally. We are not saying that taking these steps will prevent dementia, rather that evidence shows there are things you can do to help lower your chances of developing dementia. This article is to encourage readers, especially those who have made resolutions, to stay healthy this year.

Thank you
