What are the primary types of strokes?

The primary types of strokes are categorized into ischemic and hemorrhagic. Ischemic strokes occur when a blood vessel supplying blood to the brain is obstructed, typically by a blood clot or plaque buildup, leading to reduced blood flow and oxygen to the affected areas of the brain. Hemorrhagic strokes, on the other hand, result from the rupture of a weakened blood vessel, causing bleeding into the brain tissue and surrounding areas, which can increase pressure and lead to damage.

Understanding the distinction between these two main types is critical because they have different causes, risk factors, and management strategies. For instance, treatments for ischemic strokes often focus on restoring blood flow, while hemorrhagic strokes may require interventions to control bleeding and reduce intracranial pressure. Recognizing these two categories provides a foundational understanding of stroke pathology and guides clinical assessment and treatment approaches.
