This page is part of PrimeCarers' guide to dementia care. It covers the one diagnosis where the damage has a cause you can point at and a risk that can be treated.
The short answer
- The cause is the brain's blood supplyThe NHS describes vascular dementia as caused by reduced blood flow to the brain, which damages and eventually kills brain cells.
- It often moves in steps rather than a slow slideThe NHS says symptoms may get worse slowly, or in sudden steps every few months or years, with stretches in between where little changes.
- Memory is often not the first thing to goPlanning, speed of thought, mood and walking are commonly affected early, so it may not look like the dementia you were expecting.
- The risk of further damage can be treatedBlood pressure, cholesterol, blood sugar, smoking and an irregular heartbeat are all managed by the GP, and the ordinary week at home is what keeps that on track.

Why it moves in steps
Long stretches where little changes, then a drop
Alzheimer's disease is usually described as a slow decline. Vascular dementia is different because the damage arrives as events. A stroke, a run of very small strokes, or further narrowing of the small vessels deep in the brain takes away a piece of what the brain could do, and then things settle again at the new level. The NHS puts it as symptoms getting worse in sudden steps, with periods in between where they do not change much.
A stretch where little changes
After the first damage
Planning and organising are slower than they were. Cooking a meal in the right order or keeping track of a bill takes longer, and memory can be much as it always was.
What holds this stretch steady
Blood pressure, cholesterol and blood sugar reviewed and treated, and the tablets taken every day.
A step down
A stroke, a run of very small strokes, or more damage to the small vessels deep in the brain.
A stretch where little changes
After a further event
Something new appears and then settles: weakness down one side, slower speech, more confusion by the afternoon, or low mood that was not there before.
What holds this stretch steady
Rehabilitation while the change is recent, and a routine that puts the harder jobs at your relative’s best time of day.
A step down
Another event, which may be weeks away or years away. Nobody can tell you when.
A stretch where little changes
Further along
Walking and balance are harder, falls are more likely, bladder control can go, and help is needed with washing and dressing rather than only with cooking.
What holds this stretch steady
Physiotherapy, an occupational therapy visit for rails and a raised seat, and someone in the house at the hours that go wrong.
A step down
More damage, or a fall, an infection or a hospital stay that sets your relative back further than you would expect.
A stretch where little changes
Later on
Most of the day needs another person: getting up, eating and drinking enough, and moving about safely.
What holds this stretch steady
One or two carers your relative knows, so the day stays familiar.
The NHS says symptoms often continue to get worse over time, and that this may happen slowly, or in sudden steps every few months or years. Where the damage is in the small vessels deep in the brain, the Alzheimer’s Society describes the change as slow and gradual instead.
That shape is what makes vascular dementia hard to plan around. A stretch can last months or years, and there is no way to know from the outside how long the one you are on will last. It also means a drop is worth treating as an event rather than as the condition catching up: a new weakness, a new difficulty with speech or a step change in confusion is something to tell a doctor about.
Where the damage is in the smallest vessels deep in the brain, the Alzheimer's Society describes the change as slow and gradual rather than stepped, so a gradual decline does not rule the diagnosis out. Signs that dementia is getting worse covers what a change looks like when it is the condition rather than something new.
What it hits first
Planning, speed of thought, mood and walking, often before memory
What goes first depends on where in the brain the blood supply was interrupted, which is why two people with the same diagnosis can look so different. The pattern the NHS and the Alzheimer's Society describe early on is different from the memory loss dementia is usually associated with, and being told that a parent with a good memory has dementia is confusing.
Planning and following steps
Often the earliest sign
Speed of thought
Slower rather than lost
Mood and how feelings show
Commonly missed
Walking, balance and the bladder
Later, and sometimes early
Memory and language are on the NHS list too, so memory problems are part of vascular dementia rather than absent from it. They are less likely to be the thing that brings a family to the GP. The different types of dementia sets the main four side by side if the diagnosis is still being worked out, and Lewy body dementia, where alertness swings within a single day is the other type whose day-to-day pattern sets it apart.
Having more than one type of dementia at once can be the answer when the picture does not fit neatly. The NHS says some people with vascular dementia also have brain damage caused by Alzheimer's disease, and that this is known as mixed dementia. The Alzheimer's Society describes the two diseases combining to make symptoms worse than either would on its own, so a family may see a memory that fades in the way they expected alongside the slowed thinking and the steps. It changes little about the care, and nothing about the value of treating the blood supply risk below.
The overlap with stroke
Stroke and vascular dementia come from the same problem
A stroke is the blood supply to part of the brain being cut off. Vascular dementia is what follows when enough of that damage has built up. They are not two conditions that happen to occur together, and a family who has been through a stroke will recognise much of what comes next.
Twice as likely
The Alzheimer's Society states that a person who has had a stroke, or who has diabetes or heart disease, is around twice as likely to develop vascular dementia as someone who has not had these conditions.
Alzheimer's Society, who gets vascular dementia, September 2026.
If the diagnosis followed a stroke, our stroke recovery care pages apply directly. The first weeks home after a stroke is the one to read first if a discharge is coming, because the house, the routine and everybody's confidence have to be rebuilt at once. Transfers with one-sided weakness covers getting somebody safely between a bed, a chair and a toilet, which becomes the daily job when one side is weaker. Aphasia and communication is for when the words are the problem rather than the thinking behind them.
Rehabilitation still matters after a diagnosis of dementia. The Alzheimer's Society lists physiotherapy for movement problems, occupational therapy for staying independent at home, and speech and language therapy where swallowing or speaking is difficult. Ask the GP for a referral rather than waiting.
The risk that can be treated
What the GP manages, and what the week at home has to do with it
This is the part of vascular dementia that no other dementia page can carry. Nothing reverses the damage already done, and the NHS is clear that there is no cure. The risk of the next piece of damage is a different question, and it has treatments, because it is the same risk that cardiology and general practice have been treating for decades.
| What the GP looks after | What the week at home does | |
|---|---|---|
| Blood pressure | Checks it, treats it, and changes the dose when it is not where it should be. | Tablets taken at the same time every day, appointments kept, and a home monitor read at the same hour each time. |
| Cholesterol | Blood tests, and a statin where one is appropriate. | The prescription reordered before it runs out, and any side effect reported rather than the tablet being dropped at home. |
| Diabetes and blood sugar | Reviews, blood tests and the annual checks that come with diabetes. | Meals at roughly the same times, enough to drink, and someone who notices when eating has changed. |
| Smoking | Refers to a stop smoking service and can prescribe what helps. | Company at the hours the craving is worst, and fewer chances to smoke out of habit. |
| An irregular heartbeat | Finds atrial fibrillation and prescribes anticoagulants to lower the risk of a clot and a stroke. | The anticoagulant never missed or doubled, and unusual bruising or bleeding reported the same day. |

The NHS lists medicines for high blood pressure and cholesterol, low-dose aspirin or clopidogrel, anticoagulants and diabetes treatment among the treatments for vascular dementia, alongside a healthy diet, stopping smoking and exercise.
Two of these are worth saying more about. The NHS names atrial fibrillation, an irregular heartbeat, as a risk factor, and says treating it is meant to lower the risk of complications including blood clots and stroke. It often has no symptoms and is found at a routine check, so it is reasonable to ask whether your relative's heart rhythm has been checked recently. The NHS also states that the medicines given for Alzheimer's disease, such as donepezil, galantamine, rivastigmine and memantine, are not used to treat vascular dementia. If you expected a prescription at the memory clinic and did not get one, that is why, and it is not a sign that your relative has been given up on.
The ordinary week is where a family or a paid carer does the work: tablets taken at the same time each day, repeat prescriptions ordered before they run out, blood tests and annual reviews attended, and somebody who notices when eating or drinking has changed. None of it is dramatic, and it is what turns a treatment plan into treatment. Medication administration at home covers what a carer can and cannot do with medicines, mobility and falls care covers walking and balance, which becomes a risk of its own once falls start, and making the home dementia-friendly covers the light, contrast and flooring that make a house easier to read and to move around.
A sudden change
A change over hours or days should not be written off as the dementia
Once a diagnosis is in place, everything new tends to get filed under it. That is the mistake to avoid here, because two of the things that cause a sudden change are emergencies and a third is usually treatable. Work through this before deciding it is the condition moving on.

UTIs and sudden confusion goes through the infection question in full. A short note of the date and time of anything you notice is the most useful thing you can hand a doctor, because a step down is easier to recognise from two or three dated entries than from a description of how things have been lately.
Care between the steps
What a carer does on the flat stretches, and what changes after a drop
Care for vascular dementia is rarely one arrangement that lasts. It tends to mean a level of help that holds steady for a long while, then a review after an event, then a new level. Booking on that basis, rather than committing to something large at the first drop, keeps the cost and the disruption in proportion.

Rates are what carers on PrimeCarers charge, with our fee included. An agency charges £28 to £35 an hour for hourly visits and usually sends a different person each time.
The steady part of the job is the routine described above: the tablets, the meals, the appointments and the walk. What needs dementia experience is everything around slowed thinking, which means giving somebody time to answer and breaking a task into one step at a time. Where mood is low, company at a set hour each day does more than another phone call.
When your relative has dropped a step and needs more help than last month, you can search for carers near you and compare their rates, experience and availability without paying anything or booking anybody. Carers on PrimeCarers are self-employed, and PrimeCarers is an introductory service rather than a care provider or an agency. Before a carer appears, they have an online interview, and their identity, their right to work and an enhanced DBS on the Update Service are checked. They are insured while they work. What training and experience they have is their own account on their profile, so ask each carer about their dementia and stroke experience yourself.
Tell whoever you speak to what has already happened, in full. The client contract requires the client to give full and accurate information in advance and on an ongoing basis about known risks, and it names cognitive impairment among them. A carer who knows there has been a stroke and that the anticoagulant cannot be missed can plan around both.
If the help needed has grown past what visits can cover, live-in care for dementia explains how one carer in the house works, and the cost of care for dementia sets the arrangements against each other with the funding routes. If you are wondering whether home is still the right place, at what point should someone with dementia go into care is written for that decision.
Questions
Questions families ask about vascular dementia
The cause. Vascular dementia comes from reduced blood flow to the brain, which damages and eventually kills brain cells. Alzheimer's disease comes from a build-up of proteins. The difference shows at home in two ways: vascular dementia often affects planning, speed of thought, mood and walking before memory, and it can get worse in steps. The different types of dementia compares the main four.
No. The NHS says symptoms often continue to get worse over time, and that this may happen slowly, or in sudden steps every few months or years. Where the damage is in the small vessels deep in the brain, the Alzheimer's Society describes the change as slow and gradual, so a gradual decline does not mean the diagnosis is wrong.
There is no cure, and nothing reverses damage already done. The risk of further damage is treated, and that is the difference with this diagnosis. The NHS lists medicines for high blood pressure, statins, low-dose aspirin or clopidogrel, anticoagulants such as warfarin and treatment for diabetes, alongside stopping smoking, exercise and a healthy diet. Medicines used for Alzheimer\'s disease, such as donepezil and memantine, are not used for vascular dementia.
Treat it as something new until a doctor says otherwise. The NHS advises going to A&E or calling 999 if someone suddenly becomes confused, and names urinary tract infections as a common cause in older people or people with dementia. Call 999 straight away if the face has dropped on one side, an arm is weak or speech is slurred. UTIs and sudden confusion covers the infection side.
Having more than one type at once. The NHS says some people with vascular dementia also have brain damage caused by Alzheimer's disease, and that this is known as mixed dementia. The Alzheimer's Society describes the two combining to make symptoms worse than either would alone. It changes little about day to day care.
It depends on which stretch you are on. Visits are £18 to £25 an hour on PrimeCarers with our fee included, a sleeping night is £130 to £145, and live-in care starts at £1,050 a week, or £1,260 where needs are more complex. Look for carers who describe dementia and stroke experience on their profile, and ask each one about it yourself. The cost of care for dementia covers funding as well as price.
