I appreciate that many of you who have been kindly following the blog for a long time will have seen this post before. However, if you are new to Smorgasbord, I hope you will find interesting.
The Brain – Part Three – Dementia and Alzheimer’s Disease
Dementia is actually a collective name for progressive degenerative brain diseases, which affect our memory, thought, behaviour and emotions. It is not a normal result of ageing and it does not seem to have any specific social, economic, ethnic or geographical links. It can effect different people in different ways, which makes it difficult sometimes to diagnose and to treat.
Certain dementia, such as vascular dementia, where plaque is blocking the blood vessels in the brain are linked to lifestyle related causes such as heavy alcohol consumption. Most dementia is likely to have an element of environmental, diet or lifestyle involved in its development.
There is no known cure, but there are ways that we can modify our lifestyle to reduce our risks of brain degeneration and to slow down any process that has already begun.
Alzheimer’s disease is the most common form of dementia and accounts for around 60% of all cases. The disease is degenerative over a period of years and destroys brain cells and nerve cells causing a disruption to the transmitters, which carry messages in the brain, particularly those that are responsible for our memories.
As the disease progresses, the brain shrinks and gaps develop in the temporal lobe and hippocampus. These areas are responsible for storing and retrieving new information. The damage results in a reduction in a person’s ability to remember events that happened in the short term, to speak, think and to make decisions. All this is both frightening and confusing, as a person will be aware of these lapses in the early stages of the condition.
What are the symptoms of Alzheimer’s
In the beginning, there may be infrequent lapses in memory, forgetting where keys have been left or perhaps failing to switch off electric cookers or other equipment. A person will start to forget the names of everyday objects or people that they are usually very familiar with. They can also suffer from mood swings and panic attacks.
As the disease progresses these symptoms worsen and there is an element of confusion over completing every day tasks such as shopping, cooking and more dangerously driving.
The changes in personality are often attributable to fear and the awareness that something is very wrong. In the earlier stages people tend to try and hide the symptoms. This happens because, much of the time, they will be aware that there is a problem and will not want to accept that this could be as serious a condition as dementia.
In the advanced stages it is not only extremely stressful for the person concerned but also very distressing for their immediate family. We have experience of the problem with a close family friend who was in his 80’s and was looking after his wife who had Alzheimer’s for two years before she went into a home. At that point he was no longer able to cope. She was in danger of hurting herself as she was wandering off in the middle of the night, falling over and hurting herself as well as becoming terrified and disorientated. My own mother in the last two years of her life became increasingly confused but she was nearly 95 when she died. She had family and remained in her own home but for future millions who perhaps have not surviving family it will be a challenge for them and the care services.
What are the risk factors?
It is difficult to pinpoint the exact cause of dementia, but there are several probable links that have been the subject of research in recent years.
There is some evidence of a genetic link to the disease, but that is not proven. Lifestyle most definitely will have played a contributory role as exposure to toxins from smoking, excessive alcohol consumption or work environment will cause damage to the body as a whole and certainly to the brain. There is obviously natural age related degeneration of the entire body and its systems to take into account and any previous head trauma may be part of the problem. There are links to chemical contamination including poisoning from mercury – which can be found in some of the fish that we eat – and also from aluminium, which is most commonly linked to the metal in some of our cooking utensils.
Some recent statistics suggest that at least 10% of those over 65 and 50% of those over 85 years old will be suffering from varying degrees of dementia. We unfortunately have no control over natural ageing, or our genetic background, which means that we should be looking at ways to prevent or minimise the risk of us developing the disease from a much earlier age than our 60’s.
What preventative measures can we take – starting today?
- The key factors to reducing your risk of developing dementia and Alzheimer’s disease in particular are very simple and effective.
- Your brain is a major organ of the body that requires nutrients to function efficiently and to repair and protect itself. There are specific foods that provide those nutrients and including them in your diet on a very regular basis will be effective.
- You need to keep your heart and arterial system clear of oxidised LDL cholesterol and working efficiently to enable vital nutrients and oxygen to reach the brain. However, cholesterol is essential for the body and is involved in many processes including the production of hormones and therefore brain function. Reducing total cholesterol can therefore impact your brain health. Healthy fats are essential in various forms.
- You must work the brain as you would any muscle in your body. Stimulating activities strengthen brain cells and the connections between them and may even create new nerve cells.
- We all need people around us and it is even better if we involve ourselves in activity that requires mental and physical co-ordination.
- Physical exercise maintains healthy blood flow to all our organs including the brain where it will prolong the health of existing brain cells by preventing any further damage.
The one way to deal with an overwhelming fear is to face it and take control of it. For me that has meant a radical change in lifestyle. At one time I smoked over 40 cigarettes a day and drank more than was good for me. My diet was atrocious and I was morbidly obese. I was certainly in a high-risk category for declining brain health, if I had lived long enough to develop the disease.
That is not to say that you have to totally abstain from everything that gives you pleasure. We only have one life and whilst I am totally anti smoking these days, I do believe that we should balance our lifestyle with our pleasures factored in. You will often find me quoting my 80/20 rule. If you follow a healthy lifestyle 80% of the time and the other 20% indulge yourself a little then you will be on the right track.
Reduce the Risk
- Good Nutrition and hydration.
- Low levels of plaque in our arteries so that oxygen can get to the brain
- Exercise your brain as well as your body
- Social interaction

A little bit about me nutritionally.
A little about me from a nutritional perspective. Although I write a lot of fiction, I actually wrote my first two books on health, the first one, Size Matters, a weight loss programme 20 years ago. I qualified as a nutritional therapist and practiced in Ireland and the UK as well as being a consultant for radio. My first centre was in Ireland, the Cronin Diet Advisory Centre and my second book, Just Food for Health was written as my client’s workbook. Here are my health books including a men’s health manual and my anti-aging book.
