Stroke
David Friedgood, DO
, Stroke - definition
• A sudden loss of brain function caused by
blockage or rupture of a blood vessel to the
brain
• Associated Neurologic deficit
– loss of muscular control
– loss of sensation or consciousness
– dizziness
– Speech disturbance / aphasia
– Visual disturbance / diploplia, hemiaopsia
, Definitions
• Stroke is a medical emergency
• Prompt recognition, evaluation, and
treatment can minimize brain damage
• Stroke can be treated and prevented
– Risk factor management
• Synonym = Brain Attack
– Avoid ‘CVA’
, Transient Ischemic Attack (TIA)
• A TIA is a stroke
– Symptoms usually resolve in minutes
– Symptoms may persist up to 24 hours
• Symptoms of Neurologic deficit similar to
completed stroke
– 2° temporary decrease in local cerebral blood
flow
– May be associated with MRI evidence of acute
ischemia
