Dementia notes
Dementia misunderstandings
Perhaps not surprisingly, as there is still much to learn about the condition, there is much misunderstanding and confusion about dementia. In general, we still don’t know exactly what causes it and although there are treatments, there is no known cure. However, there are certain things we can say for definite and which should help you understand the disorder.
Dementia is not a natural part of ageing. If it was, everyone over the age of 65 would have it. It also occurs in younger people too.
You cannot catch dementia – it is not contagious.
People with dementia are not children, and will respond to how you treat them. They can still understand what is going on, even if they can’t tell you they understand.
Many people with dementia, with the right support and access to help and information, can lead productive and happy lives for many years.
Is it on the increase?
The outbreak of coronavirus (COVID-19) has led to unprecedented changes in the work and behaviour of general practices, therefore data relating to any primary care activity undertaken or recorded during the pandemic (March 2020 onwards) has to be interpreted with caution.
The main points are[1]:
since April 2020, there has been a consistent pattern of lower diagnosed prevalence rates for dementia in over 65 year-olds compared to before the pandemic
since January 2020, there has been a consistent pattern of lower proportions of dementia patients receiving a care plan or review compared to before the pandemic, with the gap widening as the year progressed
the variation across England of the proportion of patients receiving a care plan or review has increased significantly in December 2020 compared to before the pandemic
since March 2020, there has been a consistent pattern of higher antipsychotic prescribing rates for dementia patients compared to before the pandemic
About dementia
It is normal for memory to be affected by stress, tiredness, certain illnesses and medicines. But if you're becoming increasingly forgetful and it's affecting your daily life, particularly if you're over the age of 65, it's a good idea to talk to a GP about the early signs of dementia.
Dementia is not only about memory loss. It can also affect the way you speak, think, feel and behave.
What is dementia
Dementia is a syndrome (a group of related symptoms) associated with an ongoing decline in brain functioning. It’s caused by different diseases that damage the brain. The symptoms get worse over time and include:
memory loss
confusion and needing help with daily tasks
problems with language and understanding
changes in behaviour.
Dementia is progressive, which means symptoms may be relatively mild at first, but they get worse over time.
There are many different causes of dementia, and many different types.
People often get confused about the difference between Alzheimer's disease and dementia. Alzheimer's disease is a type of dementia and, together with vascular dementia, makes up the majority of cases.
Alzheimer's disease
Alzheimer’s disease is a physical disease that affects the brain. It is named after Dr. Alois Alzheimer, a German physician who in 1906, first described "a peculiar disease" — one of profound memory loss and microscopic brain changes. Microscopic changes in the brain begin long before the first signs of memory loss. The brain has 100 billion nerve cells (neurons). Each nerve cell connects with many others to form communication networks. Groups of nerve cells have special jobs. Some are involved in thinking, learning and remembering. Others help us see, hear and smell.
To do their work, brain cells operate like tiny factories. They receive supplies, generate energy, construct equipment and get rid of waste. Cells also process and store information and communicate with other cells. Keeping everything running requires coordination as well as large amounts of fuel and oxygen. Scientists believe Alzheimer's disease prevents parts of a cell's factory from running well. They are not sure where the trouble starts. But just like a real factory, backups and breakdowns in one system cause problems in other areas. As damage spreads, cells lose their ability to do their jobs and, eventually die, causing irreversible changes in the brain[2].
Vascular dementia
Vascular dementia is the second most common type of dementia (after Alzheimer's disease). Everyone experiences it differently. Symptoms vary depending on the person, the cause and the areas of the brain that are affected. The most common symptoms of vascular dementia during the early stages are:
Problems with planning or organising, making decisions or solving problems
Difficulties following a series of steps (such as when cooking a meal)
Slower speed of thought
Problems concentrating, including short periods of sudden confusion.
A person in the early stages may also have difficulties with their memory and their language.
Many things increase a person’s chances of developing vascular dementia. For example, their age, other health conditions and lifestyle factors.
These are called ‘risk factors’:
Ageing – The biggest risk factor for vascular dementia is ageing. Once a person gets to 65, their risk of developing the condition roughly doubles every five years.
Health conditions – There are lots of health problems that increase a person’s risk of developing vascular dementia. These include:
cardiovascular disease
cerebral amyloid angiopathy (CAA)
sleep apnoea
Lifestyle factors, such as:
Physical inactivity
Smoking
Unhealthy diet
Too much alcohol
Ethnicity – People from Black African, Black Caribbean or South Asian ethnic groups in the UK have a higher risk of diabetes and cardiovascular diseases than people from White ethnic groups, especially if they are overweight. This means they may also have a higher risk of vascular dementia.
Most people who are living with dementia have Alzheimer’s disease or vascular dementia. However, many other diseases and conditions can also cause dementia:
Dementia with Lewy bodies (DLB) – is a type of dementia caused by Lewy bodies, which are clumps of protein in the cells of the brain. In this disease, tiny clumps of proteins known as Lewy bodies appear in the nerve cells of the brain. Lewy bodies cause a range of symptoms, some of which are shared by Alzheimer’s disease and some by Parkinson’s disease. For this reason, DLB is often wrongly diagnosed. About 1 in 10 people with dementia has DLB.
Frontotemporal dementia (FTD) – is sometimes called Pick's disease or frontal lobe dementia. The first noticeable FTD symptoms are changes in personality and behaviour and/or difficulties with language. There are two broad types of Frontotemporal dementia:
Behavioural variant FTD – where damage to the frontal lobes of the brain mainly causes problems with behaviour and personality.
Primary progressive aphasia (PPA) occurs when damage to the temporal lobes – on either side of the head nearest the ears – causes language problems.
Mixed dementia – is a condition in which a person has more than one type of dementia
Young-onset dementia – There are around 900,000 people in the UK living with dementia, and the likelihood of developing dementia increases significantly with age. When a person develops dementia before the age of 65, this is known as ‘young-onset dementia’. Over 42,000 people in the UK are living with young-onset dementia. Like all people with dementia, younger people may experience a wide range of symptoms, especially in the early stages of dementia. However, they are likely to need different support from older people.
Alcohol-related dementia – is a type of alcohol-related brain damage (ARBD). If a person has alcohol-related ‘dementia’ they will struggle with day-to-day tasks. This is because of the damage to their brain, caused by regularly drinking too much alcohol over many years. The person may have memory loss and difficulty thinking things through. They may have problems with more complex tasks, such as managing their finances. The symptoms may cause problems with daily life. For example, the person may no longer be able to cook a meal.

Your role[3]
By developing an understanding of dementia, you could make someone who is feeling isolated feel valued and welcome. You are in a position where you can influence the experience of a person with dementia. Thoughtful and helpful service from you could make a big difference to someone who is feeling vulnerable. You could also directly help somebody in difficulty or a situation that is uncomfortable for them or others.
People experience dementia in different ways and they can be affected differently by the people and environment around them. In the UK 900,000 people are living with dementia[4]. They – along with their carers, friends and family members – depend on a wide range of products and services. They are looking for organisations that show support and understanding. Don’t underestimate how important your knowledge and understanding might be.
When you are assisting a person with dementia, remember the following points.
Firstly, allow the person to take their time.
Try to understand how they might be feeling.
Put the person at ease – be friendly and smile.
Consider their feelings and respond to the emotions they are expressing.
If they are experiencing difficulty or appear distressed, ask direct questions such as whether there is someone they would like you to call, rather than ‘What would you like me to do?’
Communicate clearly
The key to helping someone is being able to communicate with them. A person with dementia may not understand what you are doing or remember what you have said. Treat them respectfully by addressing them in conversation as well as any partner or carer they may be with.
Body language and physical contact
Make eye contact
Make sure that your body language and facial expressions match what you are saying.
Never stand too close or stand over someone to communicate.
Do not cover your mouth. The person should be able to see your face clearly.
Speak clearly and calmly.
Use short, simple sentences.
Speak at a slightly slower pace.
Avoid speaking sharply or raising your voice.
Don’t talk about people with dementia as if they are not there or talk to them as you would to a young child.
Listen carefully to what the person is saying, and give them plenty of encouragement.
If you haven’t understood fully, tell the person what you have understood and check with them to see if you are right.
If possible, use visual clues – write your message down if the person is able to read and use objects or pictures to help the person understand. For example, show the person photographs of meals they can choose from.
Dealing with a difficult situation
Customer service can sometimes be demanding and stressful. Practise your techniques for coping when your role is challenging and you are helping someone with dementia who is experiencing difficulties. Remember the following tips:
Stay calm.
Keep your breathing even.
Reassure the person with dementia or anyone with them that they are not under any pressure.
Explain to anyone else concerned that the situation is under control and that it will be resolved as soon as possible.
If the situation remains difficult, ask a colleague or supervisor for assistance.
