CEREBROVASCULAR
ACCIDENT
,INTRODUCTION
• Strokes occur due to problems with the blood supply to the brain: either
the blood supply is blocked or a blood vessel within the brain ruptures,
causing brain tissue to die.
• CVA is a medical emergency, and treatment must be sought as quickly
as possible.
• According to the World Health Organization, approximately 15 million
people suffer stroke worldwide each year; about one every 40 seconds.
,• Of these, 5 million die and another 5 million are permanently disabled.
• Stroke is the third leading cause of death. More than 1,40,000 people
die each year from stroke in western countries.
• Incidence rate of Stroke in India is between 145-154 per 100,000
individuals a year & is slightly higher in rural areas as compared to urban
because of poverty & poor quality of life.
, DEFINITION
• Cerebrovascular Accident is also known as STROKE.
• Stroke is a sudden interruption of the blood supply to the brain.
• According to W.H.O - Stroke is a rapid loss of brain function leads to
NEUROLOGICAL DEFICIT OF Sudden onset With focal rather than global
dysfunction In which, after adequate investigations, symptoms are
presumed to be of non-traumatic vascular origin and last for >24 hours.
• Disturbance in the blood supply to brain. A stroke happens when blood flow to a
part of the brain stops and it is sometimes called a “brain attack”
• TIA (Transient Ischemic Attack)- is a neurological deficit of vascular origin
lasting from few minutes to hours and resolves within 24 hours.
