Cerebral Vascular Accident Review Flashcards
What are the most common sites for a stroke to occur?
Common carotid artery, main bifurcation of the MCA, and the junction of the vertebral arteries with the basilar artery
What are some common things sings with a MCA lesion?
- Contralateral hemiplegia, mostly upper extremities
- Homonymous hemianopsia
- May produce aphasia and apraxia if in dominant side of brain
- Can also cause global aphasia if occlusion occurs in main stem of MCA
What are some common things seen with an anterior cerebral artery stroke?
Rarely involved
Lower extremity more frequently affected (contralateral hemiplegia)
Can result in mental confusion, aphasia, and contralateral neglect
What common occurs with a posterior cerebral stroke?
Persistent pain syndrome or contralateral pain and temperature sensory loss
Homonymous hemianopsia, aphasia, and thalamic pain syndrome
Which artery is often affected if a patient has a high chance of death, has a result of quadriplegia and “locked-in syndrome”
Vertebral-basilar
If the anterior inferior cerebellar artery is affected what are common symptoms.
Unilateral deafness, loss of pain and temp on contralateral side, paresis of lateral gaze, unilateral corners syndrome, ataxia, vertigo, and nystagmus
Describe the 6 stages of recovery following a stroke
- Flaccidity is present with no voluntary movement
- Synergies may appear. Spasticity begins to develop
- Spasticity increases and may become severe. Voluntary control of synergies appears
- Some movement independent of the synergies. Spasticity begins to decline
- Spasticity is gone. Coordination and movement approaches normal.
What are the 2 types of synergies.
Flexion and extensor synergies
Describe an upper extremity flexion synergy
Scapular elevation/retraction
Shoulder abduction and ER
Elbow flexion (generally the strongest)
Forearm supination and wrist/finger flexion
Describe a lower extremity flexion synergy
Hip flexion (generally strongest), abduction, ER
Knee flexion
Ankle DF and inversion
Toe DF
Describe the perceptual problems associated with a right hemisphere stroke
Problems with spatial relationships and hand eye coordination
Irritability, short attention span
Can’t retain information, difficulty learning individual steps
Poor judgement affecting personal safety
Diminished body image with left-sided neglect
Quick and impulsive
Describe the perceptual problems associated with a left hemisphere stroke
Apraxia Difficulty starting a sequencing task Perseveration Easily frustrated with high levels of anxiety Inability to communicate verbally Cautious and slow
Describe fluent aphasia
(receptive aphasia, Wernicke’s). Speech is preserved but auditory comprehension is impaired.
Describe Non-fluent aphasia
(expressive, Broca’s) Speech is awkward or restricted. Phrase questions for simple yes/no responses
