12 Warning Signs of Vascular Dementia

ARTICLE & VIDEO:

What is vascular dementia, the second most common of the dementias? What causes it? Can it be prevented or cured? Learn more.


Vascular dementia is caused by conditions such as stroke that disrupt blood flow to the brain and lead to problems with memory, thinking, and behavior. It is the second most common dementia diagnosis after Alzheimer’s disease and can occur alone or alongside another form of dementia.

What Causes Vascular Dementia?

Vascular dementia is caused by conditions that damage blood vessels in the brain and interrupt the flow of blood and oxygen to the brain.

In the research community, these conditions are known as vascular contributions to cognitive impairment and dementia (VCID). The brains of people with vascular dementia often show evidence of prior strokes, thickening blood vessel walls, and thinning white matter — the brain’s connecting “wires” that relay messages between regions.

Not everyone who has had a stroke will develop vascular dementia. A person’s risk for dementia after stroke depends on the size and number of strokes and the brain regions affected.

Vascular dementia can also result from other conditions that impede blood flow and delivery of oxygen to the brain, such as narrowing of the arteries.

High blood pressure, problems with the heartbeat’s rhythm, diabetes, and high cholesterol can increase a person’s risk of vascular dementia.

By controlling or managing risk factors, you may lower your chance of developing cognitive impairment and dementia.

What Are the Signs and Symptoms?

Symptoms of vascular dementia can appear suddenly and may progress slowly over time. Symptoms often look similar to those of Alzheimer’s disease, but memory loss is more prominent in Alzheimer’s, whereas problems with organization, attention, and problem-solving may be more obvious in vascular dementia.

People with vascular dementia may experience:

  1. Difficulty performing tasks that used to be easy, such as paying bills
  2. Trouble following instructions or learning new information and routines
  3. Forgetting current or past events
  4. Misplacing items
  5. Getting lost on familiar routes
  6. Problems with language, such as finding the right word or using the wrong word
  7. Changes in sleep patterns
  8. Difficulty reading and writing
  9. Loss of interest in things or people
  10. Changes in personality, behavior, and mood, such as depression, agitation, and anger
  11. Hallucinations or delusions (believing something is real that is not)
  12. Poor judgment and loss of ability to perceive danger

Symptoms may depend on the size, location, and number of damaged areas of the brain.

How is it Diagnosed and Treated?

To diagnose vascular dementia, a doctor may ask about problems with daily activities, conduct memory or thinking tests, and speak with someone who knows the person well to see if symptoms of dementia are present.

Medical history, lifestyle, and brain imaging tests are often used to help determine whether vascular dementia is the cause of symptoms.

No treatments are available to reverse brain damage that has been caused by a stroke. Treatment for vascular dementia focuses on preventing future strokes.

Medications to prevent strokes, such as blood thinners, may help decrease the risk of further damage to the brain.

Medications that help treat the symptoms of Alzheimer’s disease might benefit people with early vascular dementia. A doctor may also recommend treating risk factors, such as high blood pressure or high cholesterol, through medications and lifestyle changes.

What Can You Do?

A healthy lifestyle is important to help reduce risk factors of vascular dementia.

This includes eating well, limiting alcohol, not smoking, exercising, and managing stress.

If you are concerned about vascular dementia symptoms, talk with your doctor.

Welcome

This site was inspired by my Mom’s autoimmune dementia.

It is a place where we separate out the wheat from the chaffe, the important articles & videos from each week’s river of news. With a new post on Alzheimer’s or dementia appearing on the internet every 7 minutes, the site’s focus on the best information has been a help to many over the past 15 years. Thanks to our many subscribers for your supportive feedback.

The site is dedicated to all those preserving the dignity of the community of people living with dementia.
