Senior health: Ways older adults can lower stroke risk and safeguard brain function

By Dr. Abdullah Ibish, Guest columnist

The chance of stroke rises as people age, but many strokes can be avoided. By learning your personal risk factors and making steady, simple changes, you can help protect your brain and preserve your independence as you grow older.

Whether you are traveling, spending time with loved ones or keeping up with your usual routines, focusing on stroke prevention can help you keep doing the things that matter most.

Knowing your stroke risk

Several common health issues can raise the odds of stroke, particularly for older adults. These include:

• High blood pressure — the leading cause of stroke.
• Diabetes.
• Atrial fibrillation (AFib) — the most common type of irregular heartbeat.
• High cholesterol.
• Too little physical activity or smoking.

One difficulty is that many of these conditions may not cause obvious symptoms. High blood pressure, for instance, is often called a “silent condition” because it can go undetected without routine medical visits.

The most important first step is straightforward: Know your numbers. Visit your primary care doctor at least once a year for a preventive exam and complete any blood tests that are recommended. Talk with your doctor about your blood pressure, blood sugar, total cholesterol, LDL and HDL cholesterol, and triglyceride levels.

Keeping track of these measurements over time can help spot changes early and show whether lifestyle adjustments, closer monitoring or treatment may be needed.

Small changes can make a major difference

You do not have to transform your lifestyle all at once to lower your stroke risk. Small, manageable habits can add up over time.

Here are a few practical ways to begin:

• Take medications as prescribed: This is one of the most effective ways to manage chronic conditions such as high blood pressure or AFib.
• Be active on most days: A brisk walk, a morning stretching routine or water aerobics can improve circulation and overall heart health. Aim for at least 30 minutes of activity on most days.
• Eat heart-friendly meals: Choose fruits, vegetables, whole grains and lean proteins, and reduce salt and processed foods.
• Keep follow-up visits: Regular screenings and checkups help your care team identify health changes early.
• Avoid smoking and limit alcohol: Smoking and heavy alcohol use can raise stroke risk.

These habits can support both your long-term health and your ability to live independently. Even ordinary activities, such as walking to the park or playing outside with grandchildren, can help keep you moving.

Still, even good habits and proper medical care cannot prevent every stroke.

Spotting stroke warning signs

That is why it is essential to know the warning signs and respond quickly. Medical professionals often say, “Time is brain,” because the sooner emergency care starts, the better the chance of limiting brain injury and lasting disability.

A simple way to remember the warning signs is the acronym “BE FAST”:

• B for balance: Sudden loss of balance or coordination.
• E for eyes: Sudden trouble seeing in one or both eyes.
• F for face: One side of the face droops or feels numb.
• A for arms: One arm becomes weak or drifts downward.
• S for speech: Speech becomes slurred or hard to understand.
• T for time: If you notice any of these signs, call 911 right away.

Other symptoms can include sudden confusion, dizziness or a severe headache with no clear cause. Stroke care is time-sensitive, so do not wait, try to drive yourself or ignore symptoms if they improve. Call 911 immediately so the medical team can determine the type of stroke and begin the right treatment.

Quick action can lower the risk of long-term disability and improve the chance of recovery.
