Understanding Vascular Dementia
Vascular dementia refers to changes in thinking, memory, and behavior caused by conditions that reduce or block blood flow to the brain. These changes occur when blood vessels are damaged, limiting the brain’s access to oxygen and nutrients needed for normal function.
Vascular dementia most commonly results from two related conditions: stroke and microvascular disease. Symptoms and progression can vary widely depending on the location, severity, and number of blood vessel injuries.

Risk Factors and Vascular Health
Uncontrolled high blood pressure (hypertension) is one of the most significant risk factors for vascular dementia, stroke, and microvascular disease.
Hypertension is now defined as blood pressure consistently at or above 130/80, a lower threshold than in previous guidelines. Although common, high blood pressure often causes no noticeable symptoms, allowing damage to occur silently over time.
Vascular damage from untreated hypertension can affect organs throughout the body, including the brain, increasing the risk of stroke and long-term cognitive decline.
Other modifiable risk factors include:
- Smoking
- Diabetes
- High cholesterol
- Atrial fibrillation (an abnormal heart rhythm)

Preventing Stroke and Vascular Dementia
There are important steps individuals can take to reduce the risk of stroke and vascular dementia by protecting blood vessel health.
Key prevention strategies include:
- Establishing regular care with a healthcare provider to identify and manage risk factors
- Maintaining blood pressure at or below 130/80
- Managing diabetes, cholesterol, and heart rhythm disorders
- Avoiding smoking and staying physically active
Learning to recognize the warning signs of stroke is also critical.

Recognizing Stroke Symptoms: BE FAST
Prompt treatment can reduce brain damage and improve outcomes. The BE FAST mnemonic helps identify common stroke symptoms:
- B — Sudden difficulty with balance
- E — Sudden vision problems, including loss of vision or double vision
- F — Sudden facial droop
- A — Sudden weakness of an arm or leg
- S — Sudden slurred speech or difficulty speaking
- T — Time to call 911 immediately
