Why modern life is making dementia in your 40s more likely

Why modern life is making dementia in your 40s more likely

An MRI scan of a human brain: dementia sufferers are becoming younger.

My interest in neurological disease was triggered by a second friend dying ofmotor neurone disease (MND), which in purely statistical terms was exceptional. It is suggested there is an incidence of about one in 50,000 who are affected by MND and most die. No one knows 50,000 people, so was it a statistical fluke?

This raised the question of whether there were increases not only in MND, but in neurological disorders as a whole, including the dementias. Using World Health Organisation mortality data, which – while not perfect – is the best information available as it is collated in a standard and uniform way, myself and colleagues at the faculty of health and social sciences at Bournemouth University set out to investigate this.

Our first study, focusing on the changing pattern of neurological deaths from 1979 up to 1997, found that dementias were starting 10 years earlier – affecting more people in their 40s and 50s – and that there was a noticeable increase in neurological deaths in people up to the age of 74. In a follow-up study, taking us to 2010 and across 21 western countries, these increases were confirmed.

The results were controversial. As one newspaper headline reported: “Modern living leads to brain disease”, which in a somewhat simplistic way reflected what our research uncovered about the impact of the changing environment in which we live on our neurological health.

We are beginning to acknowledge the human impact on the natural world, but forget that we are part of the natural world

This latest neurological study, published in the USA, found that there are more people with neurological disease than ever before. Deaths of men over 75 have nearly trebled in 20 years and deaths of women have increased more than five-fold. For the first time since records began, more US women over 75 are dying of brain disease than cancer.

In the other 20 western countries, most have doubled their neurological deaths and seven countries trebled their neurological toll. It might be argued that, as people live longer, they develop diseases that they previously did not live long enough to develop. While there is some truth in this, the speed and size of the increases in just 20 years points to mainly environmental influences.

What might these environmental features be? In the past 20 years, we have quadrupled our road and air transport, with the inevitable increases in air pollution exposing us to a range of noxious substances; our background radiation has increased with the use of technological devices; there are organophosphates in our food chain. We need to recognise the interactive relationship between these minor irritants that collectively affect human health. 

We are beginning to acknowledge the human impact on the natural world, but forget that we are part of the natural world, too. The evidence for this lies in a number of clinical studies from across the developed world, showing associations with a range of petrochemical radiation, heavy metals and so on.

However, all these statistics hide the fact that the numbers are about human lives. 

Not just the patient, but also their families trying to cope with early onset dementia in a loved one, or watching a neuro-degenerative disease destroy a life before their eyes. 

Perhaps the most stark evidence of changes in the UK is the need for a new charity – Young Dementia UK – whose clients are in their 40s and 50s, while the Parkinson’s Disease Society now has a young PDS section. The speed of all these changes is making extra demands on both medical and social care, and the way we are set up to deal with this, which was barely adequate 20 years ago, is being completely overwhelmed.

What does this mean to the patient and their family? A partner will say: “I am living with a stranger, he has not known me for 10 years and the man I married died years ago, only this stranger remains.” What can be done? A possible answer lies in what governments did regarding road deaths. In 1970, there were 7,500 fatalities in the UK; by 2010, they were down to 2,220 because the governments recognised the problem and acted. We need to recognise that these results are not a statistical artefact, but a warning.

Barnard Castle works for Dementia Friendly status

It's  really lovely to hear that Barnard Castle is trying to become a dementia friendly town these days.

I have been in this market town on many occasions over the last year, as we go there at weekends etc, and I really enjoy being there. 

Since we started to go there everyone has spoken when they walked past, in fact it's been noticed that since we started to go everyone has been so friendly and so very helpful. 

So also it's no surprise to me to hear that the town wishes to become dementia friendly, simply because the shop owners have the right attitude towards their customers etc, and seem to go out of their way to be helpful.

I gather this project is being run by the Alzheimer's Societies Services manager for the Teesdale area Mark Wilkes, and I congratulate him for his efforts

My only fear for this project,  is its high volume of heavy traffic, which is taking a short cut through the town to get to and from the A66.

I confess that I find this problem to be difficult at times, but this is a problem for Durham County Coucil to sort out, as they and they alone have the power to stop this lovely historic market town being destroyed by heavy traffic taking a short cut

I know that my own town of Chester le Street has also decided to become dementia friendly, but there is a marked difference between the people and trades people in both towns.

 I confess that even though I grew up in this town, but sadly it's changed so much, that I can never ever see Chester le Street, becoming a dementia friendly town, simply because no one cares anymore. I have never seen a town go down hill so much over the years and it's sad to see. 

Chester le Street has also become a race track as motorists, who race through the town even though it's supposed to be 30 miles per hour. It's not the first time that someone has driven at me, when I was half way across the pedestrian crossing.

But the councillors here have no interest, because many of them never grew up in the area, and are yes men, in other words, you do not shake the boat as far as your political leaders are concerned. 

Those councillors who grow up in their towns and villiages, before becoming a local councillor,  have a vastly different attitude towards the general public

Dementia friendly towns need to take on board, that being dementia friendly, is not just having the title, it takes a lot of hard work, and involves many things, and to get that far, it takes a lot of hard work behind the scenes, usually by volunteers and charities

I recently wrote to Durham County Council about traffic speed, as I had done a presentation in county hall about living with dementia a few years ago. 

Yet they have since shown a total lack of interest in anything to do with this illness or any other neurological illness. It's been left to charities and the public to do the work,  and force them to do the obvious things that we all take for granted. 

As I said before speed control needs to be part of this, simply because everyone with a neurological illness has a problem in judging traffic distances and speeds etc.

So in my view its up to the towns themselves to force issues through, to make the places friendly to all, and not just to people with these illnesses. Because when a town is friendly, and traffic is controlled, etc things clip into place.

In this day and age when services are being savagely butchered by councils and this government, it's nice to see towns and villages taking the strain and working for those who struggle with Illnesses like dementia and its says a lot for those involved, 

I find it to be a real pity, that the elderly and those with these illnesses, who have worked hard and paid  their taxes for years, are seeing their local services being cut back, to the minimum.

But I do think that it's the people in these towns and villiages who are fighting back and doing things their own way.

I wish Barnard Castle the very best of luck and hope they achieve their dream of becoming a dementia friendly market town.
