Interhemispheric Fissure Stroke

Interhemispheric fissure strokes occur when blood flow to a part of the brain is interrupted. This can lead to various symptoms and complications. Understanding the causes, symptoms, diagnosis, treatment options, and prevention methods for interhemispheric fissure strokes is crucial for effective management and prevention of long-term complications.

The brain is divided into two hemispheres, and the interhemispheric fissure is the groove that separates these hemispheres. A stroke in this area occurs when there is a disruption in blood supply, leading to damage in the brain tissue. This can happen due to a blockage in blood vessels (ischemic stroke) or bleeding into the brain (hemorrhagic stroke).

Types of Interhemispheric Fissure Strokes

1. Ischemic Stroke: Caused by a blockage in the blood vessels supplying the brain.
2. Hemorrhagic Stroke: Caused by bleeding into the brain tissue.

Causes of Interhemispheric Fissure Strokes

1. Hypertension (High Blood Pressure): Prolonged high blood pressure can damage blood vessels, increasing the risk of stroke.
2. Atherosclerosis: Build-up of fatty deposits in the blood vessels can narrow or block the arteries supplying the brain.
3. Heart Disease: Conditions such as atrial fibrillation can lead to the formation of blood clots, which can travel to the brain and cause a stroke.
4. Diabetes: Uncontrolled diabetes can damage blood vessels, increasing the risk of stroke.
5. Smoking: Smoking damages blood vessels and increases the risk of blood clots.
6. Obesity: Being overweight or obese can contribute to the development of conditions such as hypertension and diabetes, increasing the risk of stroke.
7. High Cholesterol: Elevated levels of cholesterol can lead to the formation of plaques in the blood vessels, increasing the risk of stroke.
8. Family History: A family history of stroke or cardiovascular disease can increase an individual’s risk.
9. Age: The risk of stroke increases with age, especially after the age of 55.
10. Drug Abuse: Certain drugs, such as cocaine, can increase the risk of stroke due to their effects on blood pressure and blood vessels.
