Understanding Stroke: Risk Factors, Warning Signs

5/19/2026

Up to 80% of strokes are preventable because small choices we make every day can have a major impact on long-term brain health. Many of the biggest risk factors including high blood pressure, diabetes, high cholesterol, smoking, inactivity and excessive alcohol use, often begin developing much earlier in life. According to Dr. Philipp Schulz, internal medicine physician at Medical Associates at Corsicana Crossing, stroke prevention should be a priority for adults of all ages because unmanaged health conditions can quietly damage blood vessels over time, increasing the risk for strokes.

A stroke happens when blood flow to part of the brain is interrupted, either by a blockage or by bleeding in the brain. Without proper blood flow, brain cells can quickly become damaged. According to Dr. Schulz, one of the biggest contributors to stroke risk is a condition called atherosclerosis, which is the buildup of plaque inside blood vessels. An ischemic stroke occurs when blood flow to the brain is blocked. This typically happens if plaque ruptures and clogs a brain artery, or if an irregular heartbeat (like atrial fibrillation) forms a blood clot in the heart that travels to the brain.

The second major type is a hemorrhagic stroke, which occurs when a weakened blood vessel ruptures and bleeds into the brain. This is often linked to uncontrolled high blood pressure.

In some cases, people experience a transient ischemic attack (TIA), sometimes called a “mini-stroke,” before a major stroke occurs. TIAs can cause temporary symptoms such as slurred speech, weakness, confusion, vision changes or memory problems that usually resolve within 24 hours. While symptoms may go away quickly, a TIA should always be treated as a medical emergency because it can be an early warning sign of a future stroke.

Preventive care plays a major role in reducing stroke risk because many of the conditions that lead to stroke often develop quietly over time. “Patients are frequently surprised to learn they have elevated cholesterol, prediabetes, or high blood pressure because these conditions may not cause noticeable symptoms early on. Left untreated, however, they can damage blood vessels and contribute to atherosclerosis. Routine checkups and screenings allow us to identify these issues early, giving patients the opportunity to make lifestyle changes, begin treatment if needed, and prevent damage before a stroke occurs”, says Dr. Schulz.

Ignoring warning signs or delaying medical care can have serious consequences beyond the immediate risk of stroke. Dr. Schulz notes that many patients already experience symptoms such as chronic fatigue, headaches, dizziness, poor sleep, low energy, mood changes, irregular heart beat or balance problems without realizing they may be connected to underlying health conditions.

“When a stroke does occur, the long-term effects can be life-changing. Survivors may experience paralysis, loss of mobility, speech difficulties, memory problems, or permanent loss of independence. Some patients become dependent on wheelchairs, home health services, or family caregivers. Others may no longer be able to work, participate in hobbies, or maintain the quality of life they once enjoyed. Recognizing symptoms early and seeking care quickly can make a critical difference in both survival and recovery outcomes.”

Acting quickly can save a life and reduce the risk of permanent brain damage.

Remember B.E. F.A.S.T:

B – Balance: Sudden dizziness, loss of balance, or trouble walking
E – Eyes: Sudden blurred vision, double vision, or loss of vision in one or both eyes
F – Face Drooping: One side of the face droops or feels numb; ask the person to smile
A – Arm Weakness: One arm feels weak or numb; ask the person to raise both arms
S – Speech Difficulty: Slurred speech, confusion, or trouble speaking or understanding
T – Time to Call 911: If any of these symptoms appear, seek emergency medical care immediately

Quick treatment can significantly improve recovery and reduce long-term complications from stroke. Dr. Philipp Schulz is accepting new patients. To schedule, go to https://www.navarro-docs.com/doctors-providers/schulz-philipp-md-10220 or call 903-872-6065.
