What is vascular dementia?
Vascular dementia is a condition that affects thinking and memory due to reduced blood flow to the brain. When brain cells don’t get enough oxygen and nutrients, they can become damaged or die.
It often develops after a stroke or from long-term damage to blood vessels. This type of dementia can affect how you think, move, and manage daily life.
Symptoms
Vascular dementia can look different from person to person. Symptoms may appear suddenly after a stroke or develop gradually over time.
Common symptoms include:
- Trouble focusing, planning, or making decisions
- Slower thinking or difficulty following conversations
- Confusion, especially later in the day
- Changes in mood, such as depression or irritability
- Difficulty walking or maintaining balance
- Problems with bladder control
- Weakness or speech problems similar to a stroke
What causes it?
Vascular dementia happens when blood flow to the brain is reduced or blocked. This can be linked to:
- Stroke or mini-strokes
- Narrowed or damaged blood vessels
- Heart conditions affecting circulation
Risk factors include:
- High blood pressure
- Diabetes
- High cholesterol
- Smoking
- Heart disease or irregular heartbeat
- Lack of physical activity
How is it diagnosed?
Diagnosing vascular dementia involves looking at both symptoms and overall health. Your provider will ask about your medical history and changes in thinking or behavior.
You may also have tests such as:
- Blood tests to rule out other causes
- Brain imaging like MRI or CT scans
- Cognitive testing to assess memory and thinking skills
These tools help determine whether changes in brain blood vessels are contributing to symptoms.
How is it treated?
There is no cure for vascular dementia, but treatment can help slow its progression and improve quality of life.
Early treatment focuses on:
- Managing blood pressure, cholesterol, and blood sugar
- Medications to reduce stroke risk
- Healthy lifestyle changes, including diet and exercise
- Quitting smoking
Additional support may include:
- Medications for memory, mood, or behavior
- Physical or occupational therapy
Some people experience periods where symptoms stay stable, while others may notice gradual or step-like changes.
