In 2019 alone, it was the second leading cause of mortality globally and responsible for 3.4 million deaths. There are many forms of stroke, the most common being an ischemic stroke. This type of stroke occurs when a blood-vessel supplying the brain becomes blocked, cutting off oxygen and preventing it from reaching the brain. To understand how to help those recover from strokes, you must first understand the different types of strokes that occur.
