A stroke occurs when reduced bloodflow to the brain causes brain cell death. Some strokes result in permanent disability, whereas others are so mild that they go unnoticed.

What are the different Types of Stroke?

A stroke is an interruption in blood supply to the brain that causes brain cell
death. Some strokes result in permanent disability, whereas others are so mild
that they go unnoticed. Depending on where a stroke occurs in the brain and the
severity of the stroke, one or more body systems may be affected. For these
reasons, it is safe to say that stroke does not always look the same from person
to person.

The Two Major Types of Stroke:
 1. Ischemic stroke
 2. Hemorrhagic stroke



Ischemic Stroke
Over 80% of strokes are ischemic strokes, resulting when a vessel within the
brain is blocked by a blood clot or other bodily matter. This blockage reduces
oxygen-delivering blood flow and causes progressive brain tissue death. A drug
known as tissue plasminogen activator (tPA) can be given within the first few
hours of stroke to help dissolve a blood clot and restore blood flow, thereby
improving outcomes. As it may be hard to recognize the signs of a stroke
[https://www.neofect.com/us/blog/what-are-early-warning-signs-of-stroke], may
individuals miss the “window” for tPA and are treated via other means.

Hemorrhagic Stroke
Hemorrhagic strokes are less common, resulting from bleeding within the brain
and skull. Blood vessels altered by an arteriovenous malformation (AVM), brain
aneurysm, or a disease process may be more likely to rupture and bleed. A
ruptured vessel can cause blood to accumulate within the brain, compressing its
tissues and causing a dangerous increase in pressure, leading to cell death.
Hemorrhagic strokes may be treated by reducing pressure within the skull and
administering drugs to stop the bleeding.

What is a mini-stroke?
The term “mini-stroke”
[https://www.neofect.com/us/blog/ministroke-and-stroke-what-should-we-do] is
often used to describe a mild stroke-like episode from which someone recovers
quickly. This type of stroke is known as a transient ischemic attack or TIA.
Like an ischemic stroke, a TIA is caused by reduced bloodflow to the brain;
however, the symptoms of a TIA resolve within an hour. Despite the fact that a
TIA may seem like a passing event, this type of mini-stroke is usually a warning
sign of a future, bigger stroke. Over 30% of individuals who have a TIA will
have a larger stroke within the year. Therefore, it is important to discuss any
experience of stroke-like symptoms with your doctor.
