Brain swelling can happen after a stroke and the pressure that the swelling creates often damages the tissue of the brain, according to Cedars-Sinai. The permanent neurological damage after the stroke is typically greater when brain swelling is involved.
The symptoms of a stroke with or without brain swelling are the same. These symptoms include weakness of the limbs on one side of the body, double vision, slurred speech, loss of sensations on one side of the body, dizziness, inability to remain standing, problems speaking and loss of hearing, according to Cedars-Sinai. Brain swelling must be treated immediately and often leads to death when not treated quickly. The brain has little room to swell and when it swells too much, the brain tissue is squeezed against the skull, according to WebMD.
