L1.2.1.2.2: Cerebrovascular Accident (CVA)

• ● CEREBROVASCULAR ACCIDENT (CVA) — strokes

  ○ 2nd leading cause of death and 3rd leading cause of disability worldwide

  ○ Occur when blood circulation to a brain area is blocked resulting to the death of vital brain tissues

  ○ The severity of impairment depends on the location of the stroke and how much damage occurred as a result
• ● CEREBROVASCULAR ACCIDENT (CVA) — strokes

  -- Brain Lesions

  -- Aphasia

  -- Transient Ischemic Attack (TIA)

  -- Hemiplegia
• BRAIN LESIONS

  ● Damage to the brain tissue because of other causes

  ● Can cause marked changes in a person’s disposition (like having sunny to foul personality)

  ● In such cases, a tumor or CVA might be suspected
• APHASIA

  ● Common result of damage to the left cerebral hemisphere where language areas are located

  ● Most common type: motor aphasia and sensory aphasia
• TRANSIENT ISCHEMIC ATTACK (TIA)

  ● Temporary brain ischemia or restricted blood flow (because not all strokes are completed)

  ● Last from 5 to 50 minutes

  ● Temporary symptoms: numbness, paralysis, impaired speech
• HEMIPLEGIA

  ● One-sided paralysis

  ● The damage on one side indicates that the motor cortex of the opposite side is most likely involved
