One pertinent question that a lot of people ask about dementia is if it’s an old people’s disease.  Unfortunately, dementia is quite common in the elderly. It’s the leading cause of death in some countries of the world.  As one age, there are health challenges that usually start manifesting, generally, the body system gets older and gives way and they are often referred to as age-related conditions.  There are a few reasons for this. Firstly, as we age, our brains become less able to protect themselves from damage. This means that we’re more likely to develop dementia if we live long enough.

In this article, we will explore the key fact that is responsible for the prevalence of dementia among older people when compared with other age brackets. We will also look at ways it can be easily diagnosed and the best management procedure for people living with this health condition which will still ensure improved quality of life.

What is dementia and why is it common in the elderly

To start, Dementia refers to a set of symptoms that make it hard to think and remember. These can include forgetting things, feeling confused, and having trouble communicating. It is perhaps most common in older adults, and the risk of developing dementia increases with age.

There are many possible causes of dementia, including Alzheimer’s disease, Lewy body disease, and frontotemporal dementia. Dementia can be difficult to diagnose, as symptoms can vary from person to person. However, early diagnosis is important, as it can help to identify any underlying causes and direct treatment. Dementia can be a debilitating condition, but there are many support services available to help those affected by dementia to live fulfilling lives.

How to prevent dementia in old age

As dementia becomes increasingly prevalent, it is important to understand how to prevent it in old age. While there are many contributing factors to dementia, and sometimes it can be difficult to narrow down on which particular one causes the condition, paying great attention to overall health habits and behavour can go a long way to aging well, and avoiding conditions such as dementia.

Are there some predisposing factors that cause dementia, let’s explore a few of them;

A lack of social interaction and stimulation

As we get older, we often become less active and may spend more time alone. This can lead to a decline in mental and physical health

Poor nutrition

A diet lacking essential nutrients can contribute to dementia. Essentially, as much as poor nutrition can be attributed to pockets of conditions, dementia is one of them.

Sedentary lifestyle

A sedentary lifestyle can lead to a decline in physical and mental health. The ability of the brain to still be engaged and productive hinges on a good supply of oxygen and other nutrients, which sedentary living can starve it of

Excessive alcohol consumption.

Alcohol is a predisposing factor to many health conditions at all ages. It is a central nervous system depressant, which means it slows down the brain. In small doses, it can lead to problems with coordination and balance. Alcohol abuse is a major risk factor for dementia


Smoking is a predisposing factor to dementia because it increases the risk of developing other health conditions, such as cancer and heart disease, both of which are associated with it. Smoking also causes oxidative stress, which is known to damage cells in the brain

How to prevent dementia?

Now that we know some of the factors that can lead to this condition, are there things that can be done to prevent it, and ensure that one can avoid it? Several things can be done to help prevent dementia in old age:

Stay socially active.

Join a club, take a class, or volunteer. Spending time with others and staying engaged mentally can help keep it at bay.

Eat a healthy diet.

Make sure to include plenty of fruits, vegetables, and whole grains in your diet. Avoid processed foods as much as possible.

Limit alcohol consumption

Maintaining a healthy diet is important for overall health, including preventing dementia. However, one specific way to prevent dementia is to limit alcohol consumption. Excessive alcohol consumption can lead to many health problems, including dementia. So by limiting how much alcohol you drink, you can reduce your risk of developing dementia. If you drink alcohol, do so in moderation.

What are ways to reduce alcohol consumption, if you are managing dementia

There are many ways to reduce alcohol consumption, and it can be different for each individual. Some common methods include:

1. Identify why you drink alcohol.

When you understand why you drink alcohol, it can be easier to find ways to reduce or stop drinking. Maybe you drink to relax after a long day or to socialize with friends. Identifying your reasons for drinking can help you find other ways to relax or socialize.

2. Set limits on how much you drink.

If you usually have a few drinks every night, try limiting yourself to just one or two. Or if you usually drink only on weekends, try abstaining from alcohol altogether during the weekdays.

3. Avoid drinking triggers.

If there are certain places or situations where you tend to drink more heavily, try avoiding those places or situations altogether. Maybe going out for drinks with friends always leads to a night of heavy drinking, so try meeting up for coffee instead.

4. Replace alcoholic drinks with non-alcoholic drinks.

If you’re not ready to completely cut out alcohol, try replacing alcoholic drinks with non-alcoholic drinks instead. This can help slowly reduce your alcohol intake while still enjoying socializing with friends or relaxing after a long day.

5. Join a support group.

If you’re struggling to reduce your alcohol consumption on your own, consider joining a support group made specifically for people who are trying to quit drinking alcohol. There are many online and in-person groups available, and they can be a great resource for tips and advice on how to successfully reduce or quit drinking altogether

Don't smoke.

If you smoke cigarettes, now is the time to quit. Smoking is a major risk factor for dementia, so quitting can greatly reduce your chances of developing the condition.

If you are a smoker, there are many approaches you can use to help you quit smoking. Some people try to quit cold turkey, while others use nicotine patches or other medications to help them wean themselves off of cigarettes. There are also many support groups available for smokers who want to quit.

Whatever approach you choose, it is important to remember that quitting smoking is not easy, but it is worth it in the end. The benefits of quitting smoking are numerous and include improved health, reduced risk of cancer and heart disease, and longer life expectancy. Quitting smoking can be tough, but with the right support and determination, it is achievable.

By following these tips, you can help prevent dementia in old age. Stay socially active, eat a healthy diet, and limit alcohol consumption to reduce your risk.

Dementia and old age are not the same thing. Dementia is a condition that affects cognitive abilities, while old age is simply a stage of life. Many elderly people do not have dementia, and many people with dementia are not elderly.

First, dementia typically causes a decline in cognitive abilities, while old age does not. dementia can also cause changes in mood and behavior, while old age generally does not. Finally, dementia usually progresses over time, while old age does not.

If you are concerned that you or a loved one may have dementia, it is important to see a doctor for a diagnosis. Early diagnosis and treatment of dementia can improve quality of life and help slow the progression of the disease.

Treatment for dementia

Since every individual experiences dementia differently, there is not a single method of treatment that works for everyone suffering from the condition. However, some general treatment approaches can be helpful for people with dementia.

One common approach is to focus on managing symptoms. This can involve medications to help with memory loss, confusion, and other cognitive symptoms. It can also involve therapies to help with mood and behavior changes.

Another approach is to focus on promoting well-being. This can include things like social activities, exercise, and relaxation techniques. Promoting well-being can help reduce stress and improve the quality of life for people with dementia.
