VASCULAR DEMENTIA (VD)

31

Vascular dementia is the second most common cause of memory problems in older adults, but it often goes unnoticed. Unlike Alzheimer’s, which attacks brain cells directly, vascular dementia occurs when blood flow to parts of the brain is blocked or reduced. This lack of oxygen and nutrients damages brain tissue, leading to memory loss and other thinking problems.

The Key Difference:

While both Alzheimer’s and vascular dementia cause memory loss, they affect the brain differently. Vascular dementia symptoms often appear suddenly and worsen in steps, especially after a stroke. Alzheimer’s disease, on the other hand, progresses gradually over time.

Who’s Most at Risk of Vascular dementia?

Certain factors increase your risk of VD. Some you can control, while others you can’t. Here’s a breakdown:

• High Blood Pressure: This is the biggest risk factor. Keeping your blood pressure under control is crucial.
• History of Stroke: People who’ve had strokes are more likely to develop vascular dementia.
• Other Health Conditions: Diabetes, high cholesterol, smoking, and excessive alcohol use raise your risk.

Age, Race, and Gender:

• Age: Most cases occur between 60 and 75.
• Race: African-Americans are more susceptible than other races.
• Gender: Men seem to be more vulnerable than women.

Symptoms to Watch For

Symptoms vary depending on the affected brain area. Here are some common signs:

• Difficulty remembering recent events
• Getting lost in familiar places
• Difficulty concentrating or planning activities
• Trouble managing finances
• Personality changes, like inappropriate laughter or crying
• Loss of bladder or bowel control (in severe cases)
• Problems with walking or balance (can appear earlier than in Alzheimer’s)

Early Detection is Key:

If you suspect VD, see your doctor. Early diagnosis allows for interventions that can prevent further damage.

Treatment Options:

There’s no cure for VD, but treatments can help. Here’s what you can do:

• Manage Risk Factors: Controlling blood pressure, diabetes, and cholesterol can slow progression.
• Healthy Lifestyle: Exercise, a balanced diet, and quitting smoking are essential.
• Behavioral Support: Reminders, cues, and communication strategies can improve daily life for both the patient and caregivers.

How is it diagnosed?

Doctors look for symptoms that worsen in stages, unlike Alzheimer’s, which progresses steadily. Problems with balance or coordination can also be a clue, as they often appear earlier in vascular dementia.

Living with vascular dementia

• There’s no cure, but managing risk factors like high blood pressure and diabetes is key.
• Stopping smoking, limiting alcohol, and maintaining a healthy lifestyle can help.
• Behavioral therapy using reminders and cues can improve daily life for both the patient and caregivers.

Prognosis and moving forward:

• Untreated, vascular dementia can worsen over time. Strokes can cause further decline in brain function and independence.
• Early detection and management are essential. With a doctor’s help and family support, people with vascular dementia can live well-managed lives.
