Definition and Types of Stroke

A stroke broadly defines a medical condition that occurs when the blood supply to a part of the brain is interrupted or reduced, preventing brain tissue from getting oxygen and nutrients. The effects of stroke can be immediate and life-changing.

Strokes are categorized into two primary types:

Ischemic Stroke: This type accounts for nearly 87% of strokes. It occurs when a blood vessel supplying blood to the brain is obstructed. The blockage can result from a blood clot or narrowed arteries due to fatty deposits.
Hemorrhagic Stroke: This type occurs when a blood vessel in the brain bursts, leading to bleeding in or around the brain. It can arise from various conditions, such as high blood pressure or aneurysms.

Both types of stroke carry serious consequences and require prompt medical attention.

Pathophysiology of Stroke

The pathophysiology of stroke involves complex biological processes that manifest different symptoms. In an ischemic stroke, diminished blood flow leads to a lack of oxygen, which causes brain cells to begin dying within minutes. This cellular death could initiate a cascade of inflammatory responses, further exacerbating damage in surrounding tissue.

In contrast, a hemorrhagic stroke results from bleeding, which increases pressure on brain tissues and can disrupt normal function. The mechanisms of injury differ, yet both highlight the critical need for rapid intervention to mitigate brain damage.

Understanding these processes forms the foundation for developing effective treatment strategies and improving outcomes after a stroke.

Risk Factors for Stroke
