Middle cerebral artery 1 / 4
Question:
Most dysphasia's are associated with CVAs involving which artery?
Answer:
Middle cerebral *Dysphasia's are usually associated with a CVA involving the middle cerebral artery (MCA) or one of its many branches
Question:
Contralateral hemiparesis (hemiplegia)
Answer:
Paresis/paralysis of the upper and lower extremities on one side, the opposite side of the brain is affected (ex= injury to L brain = R side s/s)
Question:
A right embolic CVA has resulted in left-sided paralysis and reduced sensation of the left foot and leg. Which cerebral artery is most likely affected by the emboli?
Answer:
Anterior cerebral *Symptoms of an embolic stroke in only the right anterior cerebral artery would include left-sided contralateral paralysis or paresis (greater in the foot and thigh) and mild upper extremity weakness with mild contralateral lower extremity sensory deficiency with loss of vibratory and/or position sense and loss of two-point discrimination

Question:
Atrial fibrillation, rheumatic heart disease, and valvular prosthetics are risk factors for which type of stroke?
- Ischemic
- Embolic
- Global hypoperfusion
- Intracerebral hemorrhage
Answer:
- Embolic
*High-risk sources for the onset of embolic stroke are a-fib (15-25% of strokes), left ventricular aneurysm or thrombus, left atrial thrombus, recent myocardial infarction, rheumatic valvular disease, mechanical prosthetic valve, nonbacterial thrombotic endocarditis, bacterial endocarditis, patent foramen ovale, and primary intracardiac tumors.
Question:
Since his CVA, a man has been denying his left hemiplegia. What term is used to describe this finding?
Answer:
Anosognosia - the ignorance or denial of the existence of disease

Question:
Agnosia
Answer:
