Stroke Information

A stroke occurs when the blood supply to part of the brain is suddenly interrupted or when a blood vessel in the brain bursts, spilling blood into the spaces surrounding brain cells.

There are two types of stroke:

  1. Ischemic stroke: oxygen is cut off and brain cells die
  2. Hemorrhagic stroke: sudden bleeding into or around the brain

Symptoms of a stroke include:

  • Sudden numbness or weakness, especially on one side of the body
  • Sudden confusion or trouble speaking or understanding speech
  • Sudden trouble seeing in one or both eyes
  • Sudden trouble with walking, dizziness, or loss of balance or coordination
  • Sudden severe headache with no known cause

Deficits that may result from a stroke:

    • Language impairment, called aphasia, causing trouble with:
      • Talking
      • Reading
      • Writing
      • Understanding
    • Cognitive deficits
    • Vision impairments
    • Motor speech disorders
    • Dysarthria- muscle weakness
    • Apraxia of speech- trouble coordinating muscle movements
    • Swallowing impairments, called dysphagia
    • Paralysis or weakness of limbs
    • Changes in sensation
    • Reduced bladder control

Incidence of stroke and aphasia:

  • Every 40 seconds someone in the United States has a stroke
  • There are over 7,000,000 stroke survivors in the United States over the age of 20
  • 2/3 of all strokes occur in people over the age of 65.
  • 1/3 of all strokes occur in people under the age of 65.
  • Many stroke survivors will have chronic deficits.
  • Approximately 30% of stroke survivors will have chronic aphasia.

Recovery from stroke:

There is hope and recovery after stroke.
Work with your doctors and professionals from a wide range of health and rehabilitation professions to regain skills.
As long as you work on your recovery, your rehabilitation will continue.
