Vascular Dementia – diagnosis and treatment and support

Diagnosis

Anyone who is concerned that they may have vascular dementia (or any other type of dementia) should seek help from their GP. If someone does have dementia, an early diagnosis has many benefits: it provides an explanation for the person’s symptoms; it gives access to treatment, advice and support; and it allows them to prepare for the future and plan ahead. For vascular dementia, treatments and lifestyle changes may also slow down the progression of the underlying disease.

There is no single test for vascular dementia. The GP will first need to rule out conditions that can have similar symptoms, particularly depression. Symptoms could also be caused by infections, vitamin and thyroid deficiencies (diagnosed from a blood test) and side effects of medication.

The doctor will also talk to the person about their medical history (eg high blood pressure or diabetes). This will include questions about dementia or cardiovascular disease in close family members. The doctor will probably do a physical examination and will ask about how the person’s symptoms are currently affecting their life. The GP or a practice nurse may ask the person to do some tests of mental abilities. It is often helpful if a close friend or family member accompanies the person to medical appointments. They may be able to describe subtle changes that the person themselves has not noticed, such as starting to struggle with daily activities.

The GP may feel able to make a diagnosis of vascular dementia at this stage. If not, they will generally refer the person to a specialist. This might be an old-age psychiatrist (who specialises in the mental health of older people) based in a memory service, or a geriatrician (who specialises in the physical health of older people) in a hospital.

The specialist will assess the person’s symptoms in more detail. The way that symptoms developed – in steps or more gradually – may suggest different underlying diseases. The person’s thinking and other mental abilities will also be assessed further with a wider range of tests. In someone with vascular dementia, the test might show slowness of thought and difficulties thinking things through, which are often more common than memory loss.

A person suspected of having vascular dementia will generally have a brain scan to look for any changes that have taken place in the brain. A scan such as CT (computerised tomography) or MRI (magnetic resonance imaging) may rule out a tumour or build-up of fluid inside the brain. These can have symptoms similar to those of vascular dementia. A CT scan may also show a stroke or an MRI scan may show changes such as infarcts or damage to the white matter. If this is the case, the brain scan will be very helpful in diagnosing the dementia type, rather than simply ruling out other causes.

If the person has dementia, and the circumstances mean it is best explained by vascular disease in the brain, a diagnosis of vascular dementia will be made. For example, the dementia may have developed within a few months of a stroke, or a brain scan may show a pattern of disease that explains the dementia symptoms.

The diagnosis should be communicated clearly to the person and usually also those closest to them, along with a discussion about the next steps.


Treatment and support

There is currently no cure for vascular dementia: the brain damage that causes it cannot be reversed. However, there is a lot that can be done to enable someone to live well with the condition. This will involve drug and non-drug treatment, support and activities.

The person should have a chance to talk to a health or social care professional about their dementia diagnosis. This could be a psychiatrist or mental health nurse, a clinical psychologist, occupational therapist or GP. Information on what support is available and where to go for further advice is vital in helping someone to stay physically and mentally well.

Control of cardiovascular disease

If the underlying cardiovascular diseases that have caused vascular dementia can be controlled, it may be possible to slow down the progression of the dementia. For example, after someone has had a stroke or TIA, treatment of high blood pressure can reduce the risk of further stroke and dementia. For stroke-related dementia in particular, with treatment there may be long periods when the symptoms don’t get significantly worse.

In most cases, a person with vascular dementia will already be on medications to treat the underlying diseases. These include tablets to reduce blood pressure, prevent blood clots and lower cholesterol. If the person has a diagnosed heart condition or diabetes they will also be taking medicines for these. It is important that the person continues to take any medications and attends regular check-ups as recommended by a doctor.

Someone with vascular dementia will also be advised to adopt a healthy lifestyle, particularly to take regular physical exercise and, if they are a smoker, to quit. They should try to eat a diet with plenty of fruit, vegetables and oily fish but not too much fat or salt. Maintaining a healthy weight and keeping to recommended levels of alcohol will also help. The GP should be able to offer advice in all these areas.

Other treatment and support

Supporting a person with vascular dementia to live well includes treatment for symptoms, support to cope with lost abilities, and help to keep up enjoyable activities. For someone who has had a stroke or has physical difficulties, treatment will also include rehabilitation. Homecare Together can assist you with exercise programmes and going for daily walks. We can also assist you to continue to participate in local activities.

The drugs that are routinely prescribed for Alzheimer’s disease do not have benefits for vascular dementia, and are not recommended for it. These drugs may, however, be prescribed to treat mixed dementia (Alzheimer’s disease and vascular dementia).

If someone is depressed or anxious, talking therapies (such as cognitive behavioural therapy) or drug treatments may also be tried. Counselling may also help the person adjust to the diagnosis.

There are many ways to help someone remain independent and cope with the cognitive symptoms of vascular dementia. For example, breaking complex tasks down into smaller steps will make them easier. An environment which is not too busy or noisy will make it easier to concentrate. For someone with memory loss, a regular routine and appropriate technology, such as pill boxes/blister packs or electronic devices, can help. The person can be looked after in the safety and security of their own home with assistance from Homecare Together.

It is important that a person with any type of dementia stays active and continues to do things they enjoy. Keeping mentally active (cognitive stimulation) is known to help with memory and communication. Life story work, in which someone shares their life experiences and makes a personal record, may help with memory, mood and wellbeing. As the dementia worsens, many people enjoy more general reminiscence activities. Homecare Together carers are taught reminiscence techniques and our supervisors will also assist with these activities.

If the person has physical difficulties, for example after a stroke, they will usually benefit from rehabilitation. This could mean working with a physiotherapist (especially for help with weakness, coordination, movement and balance), occupational therapist (for everyday activities) or speech and language therapist (for all aspects of communication). Homecare Together offer allied services which include physiotherapy delivered in your own home.

The details of the support that is available, and how people are generally referred, can vary around the country. The GP can give information about what is available in the local area.

Over time, changes in the person’s behaviour – such as agitation or aggression – become more likely. These are often a sign that the person is in distress. There are many potential causes. For example, the person might be in pain, they may have misunderstood something or someone, or they may be frustrated or under-stimulated. Individualised approaches should try to address the cause. General non-drug approaches (eg social interaction) often help. They should generally be tried before additional drugs are considered, particularly in the case of antipsychotics.

Anyone caring for the person is likely to find these behaviours distressing. Support for carers is particularly important at such times. For more information contact Homecare Together on 01-534-7674 to see how we can help.
