Crosses all language modalities including:
Auditory Comprehension
Reading
Writing

How does a person become aphasic?
Cerebral Vascular Accident (CVA)
Commonly known as a stroke
Stroke (after heart disease and cancer) is the 3rd leading cause of death in the USA
Approximately 700,000 strokes/year in USA
Approximately 160,000 fatalities per year
Brain trauma
Tumors
Toxic damage (drugs and drug interactions)
What is a Cerebral Vascular accident (CVA)?
Abnormality of the brain resulting from a pathogenic process of the blood vessels
Two main Types of Strokes
Ischemic stroke – caused by blocked arteries that interrupt the blood supply to the brain
Cerebral hemorrhage – blood leakes from the artery into the brain; causes bleeding on the brain
Stroke Symptoms
American Heart/Stroke Association (FAST)
Face Arms Speech Time
Stroke Risk Factors
High blood pressure Heart disease Diabetes High cholseterol Long standing cigarette smoking Dialysis patients (kidney patients)
How is a Stroke Confirmed?
Computerized Axial Tomography (CT Scan) X-ray generator Rotates around the head Pictures taken in segments or slices – like a loaf of bread Shows shades of grey
How is a Stroke Confirmed?
Magnetic Resonance Imaging (MRI)
Generates pictures similar to a CT Scan
No radioactive material introduced into the body
Head is placed in a strong magnetic field
Spinning atoms of the brain produce magnetic properties which construct a picture of the brain
Very loud – like a washing machine
Clearer images than a CT Scan
But CT Scan is better at predicting hemorrhages
Types of Aphasia
Broca’a Aphasia or Non-Fluent Aphasia Characteristics Decreased verbal output Increased effort in speaking Shortened sentences Reduction of filler words with retention of nouns, verbs and adjectives Comprehension is better than expression Difficulty repeating Usually has weakness on the right side of the body
Wernicke’s Aphasia
Wernicke’s Aphasia or Fluent Aphasia Characteristics Poor comprehension Speech is fluent – flows and may be excessive Phrase length normal Syntax for the most part is acceptable Jargon words Nouns, verbs are usually absent
