CVA Flashcards
Sudden loss of blood supply resulting in loss of oxygen supply to the brain
Cerebrovascular accident
Incomplete stroke with symptoms lasting from a few minutes to 24 hours
Transient ischemic attacks (TIA)
caused by a thrombus or embolus
ischemic
is a rupture of a blood vessel with bleeding into the brain
hemorrhagic
Hypertension, cigarette smoking, excessive alcohol intake, high cholesterol, obesity
Controllable risk factors
Increasing age, male sex, black race, history of DM, previous CVA & TIA, family history
Uncontrollable risk factors
One sided face drop, inability to raise both arms evenly
Warning shines of stroke
Deep vein thrombosis
Most common complication of a stroke
Weakness is opposite to the side of brain damage
Hemiparesis
Paralysis is opposite to the side of brain damage
Hemipalegia
Responsible for language, time concepts, and analytical thinking. May be more depressed.
Left cerebral hemisphere (right Hemiparesis)
Partial or total loss of the ability to communicate through language.
Aphasia
Motor planning difficulties
Apraxia
Controls visual perceptual function and perception of the whole. Neglect/inattention more common
Right cerebral hemisphere (left Hemiparesis )
Difficulty in pronouncing sounds or combination of sounds
Dysarthria
Abnormal reflexes of the head and torso, coordination and balance problems, ataxia, dizziness, problems with swallowing and articulation,cranial nerve deficits-vertigo, nausea, vomiting, headache, nystagmus, slurred speech
Cerebellum stroke
Difficulty with vital signs and arousal, dizziness, problems with swallowing and articulation, cranial nerve deficits, Paralysis, likely to be critically ill and may require emergency intubation and ventilation
Brainstem stroke
Largest vessel branching off the internal carotid artery, most common cerebral occlusion site. damage to a smaller brain territory and causes less severe disability
Middle cerebral artery (MCA)
The Hallmark of the cva public awareness messages
MCA CVA
Supplies the anterior medial portion of the frontal and parietal lobes. Can cause incontinence, social appropriateness, and leg issues
Anterior cerebral artery (ACA)
Feeds the medial occipital lobe and inferior and medial temporal lobes. Right side may result in neglect; left side may result in Aphasia
Posterior cerebral artery (PCA)
Inability to perform on command (but has the ability to perform spontaneously)
Ideomotor Apraxia
Inability to form the concept of the movement-have no idea what they’re suppose to do
Ideational apraxia
Apraxia, visual perceptual deficits (not knowing or are of true midline), hemi body attention
Perceptual system dysfunction
