Strokes happen on both the left and right side of the brain. When a stroke happens on the left side of someone’s brain, it affects the right side of the body. It can also cause problems with the patient’s speech and language. If a stroke affects the right side of the brain, it affects the left side of the body. It also changes patient’s spatial (relating to space) perceptions. Getting a stroke on the right side of the brain can also cause people to not acknowledge their illness. Patients behave impulsively and neglect the side of their body.
