In this article we cover the most common symptoms of dementia and what to do if you notice these early signs.

Here’s a summary of what we will cover in this article:

  • Dementia is the term used for a collection of symptoms where brain function is impaired.
  • Dementia is progressive so it is vital to spot signs of the disease as soon as possible.
  • Common early signs of dementia include: loss of memory, slower thought processing and mental acuity decline amongst others.

What is dementia?

Dementia is a syndrome made up of a collection of symptoms, where the function of the brain declines.

Most commonly we associate it with loss of short-term memory. 

However, it can also affect mood, cause impaired judgment, and even change a person’s personality.

During the progression of the disease, brain cells become damaged and unable to repair themselves.

This damage prevents the normal communication between the cells, which leads to mood, personality and memory changes common in dementia.

Types of dementia

There are more than 400 types of dementia. The two types that are most common are vascular dementia and Alzheimers.

There is also ‘mixed’ dementia, which is a combination of these two types.

Vascular dementia affects the function of the body first, often causing mobility issues similar to a stroke.

It can also affect cognitive function, or how we think things through.

Alzheimer’s is characterised early on by memory loss and becoming confused in well-known places.

Struggling for words is also a symptom.

And here is more on what is dementia and the difference between dementia and Alzheimer’s.

don't dismiss early signs of dementia

Early signs of dementia

The early symptoms of dementia will vary greatly between individuals and can be both physical and mental.

One patient might have many symptoms, another far less.

These symptoms and signs are often mild to begin with and are often overlooked.

For example, they can initially be attributed to a poor night’s sleep.

If they become more frequent they can be blamed on not having enough to do, post-retirement. Perhaps they can even be laughed off in some cases.

Mild cognitive impairment

These symptoms may worsen very slowly, and as such are called ‘mild cognitive impairment’. Sometimes these symptoms will advance into dementia.

It is important not to measure your health against anyone else who has these symptoms, but instead seek medical help.

What to do if you notice these signs?

Some of the early signs of dementia can be dismissed as natural signs of ageing, or may not even be noticeable to you or those around you for some time. 

Symptoms could also be attributed to a different lifestyle, such as slowing down after leaving a career of many years.

However, dementia is not an inevitable part of ageing, and it is important to get a diagnosis as soon as possible.

There is currently no definitive test for dementia.

Instead there is a process of elimination undertaken whereby all other diseases are ruled out.

What will your doctor look for?

Your doctor will be able to refer you to the correct department to get all of the appropriate tests.

Blood tests and physical examinations will form part of this exploration.

You may be offered brain imaging scans to check on the condition of your brain.

Some other conditions do lead to dementia-like symptoms, such as heavy drinking and drug use, as well as strokes. A brain tumour will also need to be ruled out.

Many physical possibilities will be explored.  Also advanced cognitive tests will be applied to test both memory and processing capabilities.

When to visit your doctor

It is important to see your doctor if you, or those around you, notice any early signs of dementia.

An early diagnosis is crucial in order to plan well for the next stages of life.

This might include asking family or friends to assist with previously routine tasks.

Perhaps scheduling taxis or lifts in advance for appointments in order to attend on the right day and time.

Planning for the future

You may want to update or make important legal documents such as a will while cognitive function is still good.

Consider taking out a lasting power of attorney to service your affairs in the future.

You may also want to create an ongoing care plan with your health service or care providers.

Taking charge of your own future while in the early stages of dementia care is absolutely key.
