Lacunar Stroke - Medical Glossary

Understanding Lacunar Stroke?

Lacunar stroke affects the brain's small, deep arteries and accounts for around 20–25% of all ischemic strokes. It typically results from long-term damage due to high blood pressure or diabetes. These tiny strokes may appear minor but can cause serious effects and increase the risk of future strokes

Symptoms and Signs of Lacunar Stroke?

Symptoms may include sudden numbness or weakness, usually on one side of the body, slurred speech, facial drooping, or clumsiness in limbs. Some people may have coordination problems, difficulty walking, or visual disturbances. In some cases, lacunar strokes can occur silently with no visible symptoms.

Causes and Risk Factors for Lacunar Stroke?

The primary cause is chronic high blood pressure, which damages small arteries over time. Other risk factors include diabetes, smoking, aging, high cholesterol, and a history of stroke. These conditions contribute to narrowing or hardening of small blood vessels, increasing the likelihood of blockage.

Treatment Options for Lacunar Stroke?

Treatment focuses on preventing future strokes and minimizing damage. Doctors may prescribe blood thinners, antihypertensive drugs, cholesterol-lowering medications, and diabetes management. Rehabilitation with physical or occupational therapy may help regain strength or motor skills. Lifestyle changes are essential for long-term prevention.

When to Seek Medical Help for Lacunar Stroke?

Seek immediate medical attention if you notice sudden weakness, confusion, slurred speech, or loss of balance. Quick treatment can minimize brain damage and improve recovery chances. Even minor symptoms should not be ignored, as early intervention can prevent further complications and recurrent strokes.
