Exam Bank Questions - Part 1 Flashcards
List 4 different causes of aphasia, other than CVA.
Brain neoplasms (e.g. tumour), traumatic brain injury (TBI), CNS infections (e.g. meningitis), degenerative diseases (e.g. Parkinson’s disease, multiple sclerosis)
What is the most common cause of aphasia?
Cerebrovascular accident (CVA)
Provide a definition of “aphasia” (include 4 distinct facts as outlined by Hallowell and Chapey (2008)).
Aphasia is an acquired neurogenic communication disorder. It affects the four modalities of language (i.e. speaking, listening, reading, and writing). It does not affect intelligence.
Provide a lay definition of “aphasia” (i.e. a definition containing no speech pathology and/or medical jargon. It should include four distinct points).
Aphasia occurs suddenly and affects a person’s ability to communicate and understand. It occurs as a result of brain damage, but it does not affect a person’s intelligence. They still recognise you, they just can’t talk.
Provide a lay definition of “stroke” (i.e. a definition containing no speech pathology and/or medical jargon. It should include at least two distinct points).
A stroke occurs either due to a blockage in the blood supply to the brain, or due to too much blood flooding the brain.
List four risk factors for CVA.
Diabetes, heart disease, age, family history.
What is “atrial fibrillation” (AF or A-fib)?
A type of irregular heart beat.
Define “arteriosclerosis”.
A disease that causes atrial walls to become roughened and covered with fatty deposits.
List 2 signs of CVA which are included in the Australian National Stroke Foundation’s FAST campaign.
Face (is it drooping on one side?), arms (can they lift both of them up above their head?)
Approximately how many people develop aphasia post CVA?
Approximately 1/3.
Damage to which branch of the internal carotid artery frequently results in aphasia?
The left middle cerebral artery
Define the “watershed areas” of the brain.
Areas that have an overlap in the blood supply from the major cerebral arteries, thus providing some protection from bloody flow occlusions.
State the two major types of CVA and identify which type is most common.
Ischaemic (most common), and haemorrhagic.
Define “lacunar stroke”.
A type of ischaemic stroke that occurs due to disease of a small cerebral artery.
What is an “endarterectomy”?
A surgical procedure that removes plaque build-up within the carotid artery system.
Provide a definition of “embolus” and identify the body organ from which emboli most commonly originate.
An embolus is a blood clot or a piece of fatty plaque that forms somewhere else in the circulatory system and breaks off and travels to block off a smaller artery that supplies blood to the brain. An embolus usually originates from the heart.
Identify which major type of CVA may be treated using thrombolytic drugs and state within how many hours post onset (according to Murray & Clark, 2006) must this drug be given.
An ischaemic stroke can be treated using thrombolytic drugs. The drug needs to be given within the first 3 hours post onset.
What is the main difference between an ischaemic CVA and a haemorrhagic CVA?
An ischaemic CVA occurs due to a blockage win one of the arteries suppling blood to the brain, whereas a haemorrhagic CVA occurs when one of the arteries burst, flooding the surrounding brain tissue with blood.
Define a “transient ischaemic attack” (TIA) and list 3 symptoms an individual having a TIA may experience.
A transient ischaemic attack (TIA) is a small & temporary disruption of blood flow to the brain that doesn’t cause permanent brain damage. An individual may experience dizziness, slurred speech, & limb weakness.
What is the primary different between a TIA and a “reversible ischaemic neurological deficit” (RIND)?
A TIA occurs for less than 24 hours (usually 5-30 mins), whereas a RIND lasts for more than 24 hours.
What is the primary difference between a RIND and a “partially reversible ischaemic neurological deficit” (PRIND)?
A RIND completely resolves in a few days. On the other hand, a PRIND leaves minor deficits.
Define “arteriovenous malformation”.
An arteriovenous malformation is a congenital defect in the communication links between arteries & veins that results in weakened arterial walls.
Define “aneurysm”.
An aneurysm is a weak, or thin, spot on a blood vessel that causes the vessel to dilate or balloon.
Define “homonymous hemianopia” (also called homonymous hemianopsia).
A loss of vision on the same side of both eyes.
Define “visual neglect”.
An attentional problem to one side of the body.
Define “agnosia” and provide an example of an agnostic error that may be observed during a language assessment.
An agnosia is an inability to recognise objects through an intact sensory modality while being able to recognise the object through a different modality. For example, being unable to name an object when presented it visually, but being able to name it when he/she touches it.
Define “apraxia” in terms of a movement disorder associated with stroke.
An inability to carry out on command a motor activity that is easily performed spontaneously.
What is the primary difference between “hemiplegia” and “hemiparesis”?
A hemiplegia is paralysis on one side of the body, whereas a hemiparesis is a muscle weakness on one side of the body.
