• 5D: Impaired Motor Function and Sensory Integrity Associated With Nonprogressive Disorders of the Central Nervous System - Acquired in Adolescence or Adulthood

Description

• Results in sudden, specific neurological deficit based on location and extent of ischemia or hemorrhage
• May occur over seconds, minutes, hours, or few days
• Symptoms include sensory dysfunction, aphasia, dysarthria, dysphagia, visual field defects, cognitive impairment, and most commonly hemiplegia

Essentials of Diagnosis

• Brain damage may result in the following changes or dysfunction
  • Motor loss
  • Sensory loss
  • Visual impairment
  • Autonomic dysfunction
  • Perceptual changes
  • Cognitive, personality, behavioral changes
  • Changes in consciousness
  • Communication difficulties
  • Eating, swallowing, bowel and bladder changes

General Considerations2

• Two major classification groups
  • Ischemic (2 types)
    • Thrombotic: atherosclerotic plaques and hypertension (HTN) produce cerebrovascular accident (CVA) due to plaques that form at the branching and curves of arteries
    • Embolic: an embolus that causes CVA can travel from the heart, internal carotid artery thrombosis, or atheromatous plaque of the carotid sinus; branches of middle cerebral artery (MCA) most commonly affected
  • Hemorrhagic: hypertension (HTN), ruptured saccular aneurysm, or arteriovenous malformation (AVM) can cause a bleed in the brain

Demographics

• Largest single cause of neurological disability
• Approximately 4 million Americans suffer physical impairments and disability from stroke
• Two-thirds of all strokes occur in individuals aged 65 years or older
  • Risk of stroke doubles every 10 years after age 55
• Greater incidence in men than women; twice as likely in African Americans vs. Caucasians
• Cerebral infarction (thrombosis or embolism) is most common form (70% of all strokes), followed by hemorrhages (20%) and unspecified cause (10%)

Signs and Symptoms

• Dependent on part(s) of the brain affected by CVA and amount of tissue damage from obstruction or hemorrhage2
