How is dementia diagnosed?

If you are worried about your memory or think you may have dementia, it’s a good idea to see your GP. If you’re worried about someone else, who you think has dementia, encourage them to make an appointment and perhaps suggest that you go along with them.

If you are forgetful, it doesn’t mean you have dementia. Memory problems can also be caused by depression, stress, drug side effects, or other health problems. It can be just as important to rule out these other problems or find ways to treat them. Your GP will be able to run through some simple checks and either reassure you, give you a diagnosis, or refer you to a specialist for further tests.

An early diagnosis gives you both the best chance to prepare and plan for the future, and receive any treatment. With treatment and support from healthcare professionals, family and friends, many people are able to lead active, fulfilling lives.

What to expect when you see your GP about dementia

Your GP will ask about your symptoms and other aspects of your health, and will give you a physical examination. The doctor will organise some blood tests and ask about any medication you are taking, as these can sometimes cause symptoms similar to dementia.

You will also be asked some questions or given some mental exercises to measure any problems with your memory or your ability to think clearly.

Referral to a dementia specialist

Dementia can be difficult to diagnose, especially if your symptoms are mild. If your GP is unsure about your diagnosis, they will refer you to a specialist such as a neurologist (an expert in treating conditions that affect the brain and nervous system), an elderly care physician, or a psychiatrist with experience of treating dementia.

The specialist may be based in a memory clinic alongside other professionals who are experts in diagnosing, caring for and advising people with dementia and their families.

It’s important to make good use of your consultation with the specialist. Write down questions you want to ask, make a note of any medical terms the doctor might use, and ask if you can come back if you think of any more questions. Taking the opportunity to go back can be very helpful.

The specialist may want to organise further tests, which may include brain scans such as a computerised tomography (CT) scan, or preferably a magnetic resonance imaging (MRI) scan.

If they are still not certain about the diagnosis, you may need to have further, more complex, tests.

Getting your dementia diagnosis

Once you’ve had the necessary tests, your doctor should ask if you want to know your diagnosis.

They should explain what having dementia might mean for you, and should give you time to talk more about the condition and ask any questions you may have.

Unless you decide otherwise, your doctor or a member of their team should explain to you and your family:

the type of dementia you have, or if it is not clear, what the plan to investigate further will entail; sometimes, despite investigations, a diagnosis may not be clear, in which case the doctors will review you again after a period of time to reassess you

details about symptoms and how the illness might develop

appropriate treatments that you might be offered

care and support services in your area

support groups and voluntary organisations for people with dementia and their families and carers

advocacy services

where you can find financial and legal advice

You should also be given written information about dementia.

Questions to ask about your dementia diagnosis

In case you can’t think of any questions to ask you’re doctor, it may be worth asking:

which type of dementia you have

details about the tests or investigations you should have

how long you will have to wait until you have the tests

how long it will take to get the results of these tests

what will happen after you get the results

Ongoing dementia assessment

Once you have been given a diagnosis, your GP should arrange to see you from time to time to see how you’re getting on. Because dementia is a progressive condition, the doctor may arrange another appointment with the specialist, perhaps after six months or a year.

The GP and the specialist may also jointly prescribe medications that may be helpful in treating some of the symptoms of dementia. However, not everybody will benefit from these drugs.

An ongoing assessment of your dementia may be a good time to consider your plans for the future, perhaps including a Lasting Power of Attorney to take care of your future welfare or financial needs, or an advance statement about your future care.

Dementia – What are the early signs of vascular dementia?

Memories to help with dementia

Memories to help with dementia

Vascular dementia causes problems with mental abilities and a number of other difficulties.

The symptoms can come on suddenly or gradually. They tend to get worse over time, although treatment can help slow this down.

Early symptoms

Early signs of vascular dementia can include mild:

slowness of thought

difficulty with planning

trouble with understanding

problems with concentration

mood or behavioural changes

problems with memory and language (but these aren’t as common as they are in people with Alzheimer’s disease)

As this point, these problems may be barely noticeable or mistaken for something else, such as depression. But they indicate some brain damage has occurred and that treatment is needed.

Later symptoms

The symptoms often continue to get worse over time. This may happen slowly, or in sudden steps every few months or years.

The symptoms depend on the part of the brain that’s affected, but can include:

significant slowness of thought

feeling disorientated and confused

memory loss and difficulty concentrating

difficulty finding the right words

severe personality changes, such as becoming aggressive

depression, mood swings and lack of interest or enthusiasm

finding it difficult to walk and keep balance, with frequent falls

loss of bladder control (incontinence)

increasing difficulty with daily activities

Some people also have some symptoms of Alzheimer’s disease.

Getting medical advice

See your GP if you think you have early symptoms of dementia, especially if you’re over 65 years of age.

If it’s spotted at an early stage, treatment may be able to stop the vascular dementia getting worse, or at least slow it down.

If you’re worried about someone else, encourage them to make an appointment with their GP and perhaps suggest that you go with them.

Symptoms of dementia can have several causes. Your GP can do some simple checks to try to find out the cause and may refer you to a specialist for further tests.

Polluted Air is a Possible Cause of Dementia

Polluted Air is a Possible Cause of Dementia

Polluted Air is a Possible Cause of Dementia

There are over 850,000 people in the UK with dementia and this figure is expected to increase to over 1 million in 2025 and by 2050, it will rise to more than 2 million according to the Alzheimer’s Society. Dementia is a degenerative disease causing a decline in cognitive and mental functioning. There are many causes of dementia including head injuries, stroke or brain tumour.

Several research studies have been undertaken to better understand the causes of this condition as well as its early signs. Lately, recent evidence came to light that dementia may be linked to dirty air. Based on research findings, contaminated air can be a possible source of dementia. It is believed that high concentrations of magnetite particles found in polluted air may be linked to dementia. Researchers are trying to establish whether there is a definitive relation between magnetite found in the brains of Alzheimer patients and the onset of dementia.

Memory loss – should you be worried?

Memory loss

Memory loss

Introduction

Memory loss, also called amnesia, happens when a person loses the ability to remember information and events they would normally be able to recall.

It could be something that happened seconds or minutes ago, or a memorable event that occurred in the past. The loss of memory may have started suddenly, or it may have been getting worse over the last year or so.

It’s normal to become a bit forgetful as you get older. However, memory loss could be a symptom of something more serious and should be checked by a GP.

Memory loss can be distressing for the person affected, and their family. Relatives may fear the worst and assume it’s caused by dementia, but this often isn’t the case.

The following information will tell you:

what to do if you’re worried about memory loss

how to tell if it could be caused by dementia

the most common causes of memory loss (but don’t rely on this to self-diagnose a condition)

how to cope with a poor memory

What to do if you’re worried about memory loss


See your GP if you’re worried because you or someone you care for has lost their memory. They’ll do an initial assessment and ask questions about symptoms, family history and lifestyle. They may also arrange a blood test.

Memory loss has a wide range of possible causes, depending on the type of memory loss.

Doctors classify memories as either:

immediate memories – such as sounds, which are only stored for a few seconds

short-term or recent memories – such as telephone numbers, which stay in your memory for 15 to 20 seconds; the brain can store about seven chunks of short-term information at any time

long-term or remote memories – more permanent memories, which have been reinforced because you’ve repeatedly gone over them in your mind

If your GP thinks you or your relative needs an assessment for dementia, or that there may be another more serious underlying condition, such as brain damage, they’ll refer you to a specialist.

Could memory loss be dementia?

If you’re reading this because you think your memory problems may be a sign of dementia, rest assured that they probably aren’t. A person with dementia won’t usually be aware of their memory loss, or may deny it.

Your memory loss is likely to be caused by something much more common and treatable, such as depression.

You may be worried that someone you care for has dementia. However, bear in mind around 40% of people over 65 have some type of memory problem, and only 15% will develop dementia each year.

If your instincts are correct, their denial or lack of awareness of their memory loss can make it difficult to convince them to see a GP. This fact sheet includes information about how to persuade your relative to see a doctor (PDF, 848kb).

Signs that someone has dementia

As a general guide:

Dementia usually occurs in people over the age of 65.

The memory loss doesn’t happen suddenly, but gets gradually worse over time.

Someone with dementia will struggle to remember immediate or recent events, but can still recall events that happened a long time ago. This means that if their long-term memory is affected, it probably isn’t dementia.

Read more about the symptoms of dementia.

Common causes of memory loss

GPs often find that people who see them about memory loss are most likely to have:

anxiety

stress

depression

Their memory loss is a result of poor concentration and not noticing things in the first place because of a lack of interest. Sleeping problems often make the memory loss worse.

Your GP may suggest trying antidepressants. If you have depression or anxiety, your memory problems should get better as the depression or anxiety improves.

An elderly person with memory loss is likely to have depression if they also experience changes in behaviour, such as hoarding or being bad tempered.

Other common causes of memory loss are:

a head injury – for example, after a car accident

stroke – this cuts off some of the blood supply to the brain and causes brain tissue to die

These will cause sudden memory loss, where you either forget events that happened before the trauma (retrograde amnesia), or you forget everything that happened after the trauma (anterograde amnesia).

Less common causes of memory loss

Less commonly, memory loss can be caused by:

an underactive thyroid – where your thyroid gland (found in the neck) doesn’t produce enough hormones

certain types of medication, such as sedatives and some treatments for Parkinson’s disease

long-term alcohol misuse

bleeding in the brain (subarachnoid haemorrhage)

vitamin B1 (thiamine) deficiency – for example, as the result of a digestive problem

transient global amnesia – problems with blood flow to part of the brain, which causes sudden episodes of memory loss that a person can’t recall afterwards

psychogenic amnesia – a stressful or traumatic event that causes someone to block out the memory, leaving them unable to remember important information

a brain tumour

Tips for coping with a poor memory

Keep everyday items, such as car keys, in the same place and try to do things in the same order each time.

Write information down, and keep paper and a pencil near the phone.

Keep a diary at home as well as at work to remind you to do daily tasks.

Use an alarm to help you remember to do something in the future, such as taking something out of the oven.

Repeat important information you need to remember back to someone.
