Understanding Vascular Dementia

Vascular dementia is a type of dementia caused by disruption to the brain’s flow of blood vessels and oxygen, affecting memory and cognitive function.

What is vascular dementia?

Vascular dementia is the second most common type of dementia, affecting an estimated 180,000 people in the UK. It occurs when the flow of blood vessels and oxygen in the brain is either reduced or blocked by a blood clot, causing memory and cognitive issues.

Vascular dementia differs from other types in that it is caused by parts of the brain not having access to blood for a period of time, as opposed to other types of dementia which are caused by a buildup of abnormal proteins in the brain.

What are the most common vascular dementia symptoms?

Vascular dementia symptoms vary depending on which areas of the brain are affected, but some of the most common include:

 

  • Memory loss
  • Difficulty with communication (for example, finding the right language to use, switching up words accidentally, or having trouble processing information)
  • Difficulty absorbing new information or following instructions
  • Getting lost while walking or driving on familiar routes
  • Difficulty carrying out tasks
  • Difficulty sticking to routines
  • Frequently losing items
  • Altered sleep patterns
  • Depression, or a loss of interest in activities
  • Increased anxiety
  • Changes in behaviour, personality and mood, such as displaying agitation or becoming angry easily
  • Displaying poor judgement
  • Experiencing delusions or hallucinations

What causes vascular dementia?

Signs and symptoms of vascular dementia differ depending on how much of the brain is affected, and how severe it is. This could happen over a long period of time, or symptoms could appear suddenly after a condition that impacts blood vessels in the brain. For example:

  • Stroke (when a blood clot interrupts the blood supply to certain parts of the brain)
  • Transient Ischemic Attack (TIA), otherwise known as a “mini stroke”
  • Heart disease, as those with certain types of heart issues are more at risk 
  • High blood pressure
  • Diabetes
  • Blood clots

Cerebral autosomal dominant arteriopathy with subcortical infarcts and leukoencephalopathy (CADASIL), affecting blood vessels in the brain’s white matter

What types of vascular dementia are there?


There are several different types of vascular dementia. These include:

Type Description
Subcortical vascular dementia The most common type. Small blood vessels thicken or twist, preventing blood from flowing, and starving parts of the brain of oxygen and nutrients.
Stroke-related dementia A clot cuts off blood flow to certain areas of the brain. In these cases, around 1 in 5 develop vascular dementia within 6 months.
Multi-infarct dementia Caused by several smaller strokes, or transient ischaemic attacks (TIA).
Mixed dementia Affects 1 in 10 people with dementia, and is most commonly a mix of Alzheimer’s and vascular dementia.

What are the vascular dementia stages?

There are three main stages of dementia that tend to progress similarly in all types, but vascular dementia has some slight differences:

 

  1. Early stage – Memory lapses are present, however memory issues are less common in early vascular dementia. Instead, mood, behaviour and personality changes are common. In vascular dementia, the early stage tends to last the longest, for many months or years.
  2. Middle stage – In stroke-related vascular dementia, they may develop more intense communication or speech difficulties, and have weaker limbs that require additional mobility support.
  3. Late stage – Language deteriorates in the later stages, and alternative methods of communication are needed. In vascular dementia, brain functions continue to diminish, and as in other types of dementia, end-of-life care will eventually be needed.

What is the typical vascular dementia life expectancy?

Research suggests the vascular dementia life expectancy range is 3 to 5 years, but a person with vascular dementia could also be at risk of heart disease or stroke due to its close links to these conditions. Ultimately, every person’s experience with dementia is different, so they could live many years focused on wellbeing and quality of life before their symptoms worsen.

What risk factors contribute to vascular dementia, and can it be prevented or treated?

Risk factors involved in vascular dementia are linked to the cardiovascular system, so those with a higher risk of certain conditions–including stroke, high blood pressure, diabetes, high cholesterol, and heart issues–may have a higher risk of developing vascular dementia. Risk factors also increase for those with a family history of dementia, who are overweight, or who smoke, but living a healthier lifestyle could help to prevent vascular dementia long term.

There is no cure, so treatments are designed to delay the progression rather than reverse damage. Alongside care plans and lifestyle changes, these may include medications to treat the above conditions, and low-dose aspirin to reduce the risk of blood clots.

My loved one has been diagnosed with vascular dementia. What do I do now?

A vascular dementia diagnosis in your family can feel overwhelming, but after allowing yourself time to absorb the information, focus on gaining reliable knowledge from doctors and helpful online resources. The person’s GP or dementia care specialist can help you with some of the initial steps, such as:

  • Creating a care plan that encompasses medications, safety precautions, and routines
  • Taking steps to improve cardiovascular health and slow progression
  • Organising legal and financial documents early, such as a Power of Attorney (POA)
  • Seeking support from loved ones
  • Looking up local resources and support groups
  • Adapting their home to make it safer
  • Working on patient, clear communication
  • Considering respite care to give you regular breaks

How can families help a loved one with vascular dementia?

Maintaining quality of life is vital for a person at any stage of vascular dementia, so depending on their symptoms, families and caregivers may be able to:

  • Help them stick to regular, comforting routines
  • Encourage them to engage in social activities they enjoy to improve their wellbeing
  • Provide emotional support as they come to terms with their diagnosis
  • Help with challenging home maintenance tasks
  • Create memory prompts, such as labels or medication reminders
  • Make home adaptations to improve safety
  • Streamline their environment to minimise confusion
  • Hire professional home care to take on challenging tasks and support their safety

With a professional background that spans healthcare, aviation, and specialized training, I bring a wealth of experience to the field of dementia care. As a former Registered Nurse with expertise in Emergency and Children’s Medical care, I transitioned to a 20-year career in aviation, serving as a Cabin Director and Base Cabin Crew Manager. In these roles, I led recruitment, training, retention, and leadership initiatives for cabin crew teams across the UK.

For the past 16 years, I have been dedicated to the care sector, progressing from Care Professional to Care Manager, and later assuming roles such as Specialist Training Manager. Currently, as a Learning and Development Partner at Home Instead’s National Office, I develop and review training programs, collaborate with external organizations like the Alzheimer’s Society, and manage various impactful projects.

My passion for dementia care has guided much of my work, from engaging with advanced dementia support initiatives, such as those offered by the End of Life Partnership, to staying informed through events like the annual Dementia Summit. These efforts reflect my deep commitment to enhancing the care and quality of life for individuals living with dementia
