Nervous system




  • A "stroke" is neurological deficit of acute onset (over minutes
  • to hours) which persists for more than 24 hours. Deficits which
  • resolve within 24 hours are classified as "transient ischemic attacks"
  • (TIAs). Signs of stroke may include:

    • Impaired consciousness Diplopia
    • Monoparesis or hemiparesis Visual field defects
    • Sensory deficits Dysarthria or dysphasia
    • Ataxia of trunk or limbs

  • Plan: Define the presence of cerebral infarction, suggest the
  • etiology and assess the presence of hemorrhage. Since stroke is
  • often the result of embolic disease, anticoagulation therapy should
  • be considered; cerebral hemorrhage is a contraindication.
