How Does a Stroke Affect Your Brain?

During a stroke, the brain is either deprived of oxygen due to a blood clot in the carotid artery or one of the smaller blood vessels of the brain, or it is damaged by the force of a ruptured blood clot in the brain tissue. These types of stroke are known as ischemic stroke and hemorrhagic stroke, respectively, and they can be equally damaging to the brain with permanent effects. The video above features Sunrise Hospital neurosurgeon Michael Seiff, MD, who discusses what happens during each of these different types of stroke. In this article, you can discover how each of these processes affects the brain tissue, causing lasting disabilities that will require extensive rehabilitation to restore a patient’s independence and higher quality of life.

Brain Cell Death

Like all tissues in the body, brain cells require a steady flow of oxygenated blood to function properly. When a hemorrhage or blood clot limits oxygen in the brain, brain cells in the affected area will die, having sustained permanent damage. If a hemorrhage is discovered before it ruptures, however, treatment can restore lost brain function.

Functional Losses

Stroke can have a number of different effects, depending on the area of the brain impacted by the loss of blood flow. Many patients will experience certain aphasias that will limit the use of language, because there are various language centers throughout the brain that can sustain damage during a stroke. In other cases, damage to the brain cells might lead to paralysis, limited muscle function, incontinence, and other losses of basic bodily functions.
