Q

What kind of signs and symptoms would you see with Anterior Cerebral Artery Syndrome (ACA Stroke)?

A
  • Contralateral hemiparesis (LE is more involved)
  • Contralateral hemisensory loss (LE is more involved)
  • Urinary incontinence
  • Problems with imitation and bimanual tasks, apraxia
  • Akinetic mutism, slowness, lack of spontaneity, motor inaction
  • Contralateral grasp reflex, sucking reflex
25
What kinds of signs and symptoms would you see with Middle Cerebral Artery Syndrome (MCA Stroke)?
- Contralateral hemiparesis (UE and face is more involved) - Contralateral hemisensory loss (UE and face is more involved) - Motor speech impairment - Receptive speech impairment - Global aphasia - Perceptual deficits - Limb-kinetic apraxia - Contralateral homonymous hemianopsia - Loss of conjugate gaze to the opposite side - Sensory ataxia of contralateral limbs
26
What is apraxia?
Difficulty with planning and sequencing movements that cannot be accounted for by any other reason
27
What is Ideational Apraxia?
Inability of the patient to produce movement either on command or automatically and represents a complete breakdown in the conceptualization of the task
28
What is Ideomotor Apraxia?
The patient is unable to produce a movement on command, but he or she is able to move automatically
29
What hemisphere is apraxia more evident with?
More evident with left hemisphere damage
30
What is Broca's aphasia?
Expressive, Non-fluent aphasia (they can understand but cant respond), limited vocabulary, slow and hesitant speech (frontal lobe - M1)
31
What is Wernicke's aphasia?
Fluent aphasia (cant understand but can respond), impaired auditory comprehension, fluent speech, normal rate and melody (temporal lobe - A1)
32
What is Global aphasia?
Non-fluent speech with poor comprehension (both wernickes and brocas)
33
What is Posterior Cerebral Artery Syndrome (PCA Stroke)... in the peripheral territory?
- Contralateral homonymous hemianopsia - Bilateral homonymous hemianopsia with some degree of macular sparing - Visual agnosia - Prosopagnosia - Dyslexia - Memory deficit - Topographic disorientation
34
What is Posterior Cerebral Artery Syndrome (PCA Stroke)... in the central territory?
- Central post stroke (thalamic) pain syndrome - Spontaneous pain and dysesthesias, sensory impairments - Involuntary movements - Contralateral hemiplegia - Oculomotor nerve palsy
35
What are lacunar strokes caused by?
Small vessel disease in the cerebral white matter
36
Lacunar stroke syndromes are consistent with what?
specific anatomical sites
37
T/F: Lacunar syndromes can be motor, sensory, etc.
True
38
What kind of deficits are often NOT seen in lacunar strokes due to the higher cortical areas being persevered?
Consciousness, language, and visual fields
39
Occlusions causing Vertebrobasilar Artery Syndrome can produce what?
A wide variety of symptoms with both the ipsilateral and contralateral signs
40
Why do you get both ipsilateral and contralateral signs with vertebrobasilar artery syndrome?
Because some brainstem tracts will have crossed, and some will not have crossed yet
41
What kind of abnormalities are present with vertebrobasilar artery syndrome?
Cerebellar and cranial nerve abnormalities
42
Where is damage caused with Lateral Medullary Syndrome/ Wallenberg's Syndrome?
At the Posterior inferior cerebellar artery
43
What signs and symptoms will you see with Lateral Medullary Syndrome/ Wallenberg's Syndrome?
- Loss of pain and temperature on the contralateral side of the body and ipsilateral face - Dizziness/ vertigo - Ataxia - Diplopia - Dysphagia - Dysarthria - Horner's Syndrome
44
Where is damage caused with Horner's Syndrome?
At the sympathetic trunk
45
Horner's Syndrome has symptoms of miosis, ptosis, and anhidrosis on the _____ side.
Ipsilateral
46
What symptoms starting with the letter "D" does horners syndrome present?
- Dysphagia - Dysphonia
47
Does horners syndrome create a sensory or motor impairment of the UE, trunk or LE?
Sensory
48
What is impaired over 50% of the body, and sometimes face contralateral to the lesion with horner's syndrome?
Impaired pain and thermal sense
49
What is locked-in syndrome?
Damage caused to the basilar artery affecting the ventral pons
50
What kind of signs and symptoms might you see with locked-in syndrome?
- Tetraplegia/ quadriplegia - Bilateral cranial nerve palsy (upward gaze is spared) - Coma - Cognition is spared
51
What kind of medical imaging can be done for CVA based conditions?
- Computed Tomography (CT) - Magnetic Resonance Imaging (MRI) - Magnetic Resonance Angiography (MRA) - Doppler Ultrasound
52
What kind of acute management approaches can be taken for CVAs?
- Medical - Pharmacological - Neurosurgical
53
What is included in a comprehensive physical therapy examination?
- Patient/ client history - Systems review - Test and measures
54
What is the purpose of an examination?
- Screen for benefit of rehabilitation services and most appropriate care setting - Develop a plan of care - Measure progress towards goals/ outcomes - Determine if referral to another practitioner is needed - Plan for discharge
55
What is included in a plan of care?
- Goals - Expected outcomes - Prognosis - Interventions
56
What is included in a patient history?
- Goals - Communication and cognition screen - Age, sex, race, language, education, etc. - Social history - Occupation/ employment - Living environment/ work barriers - Hand dominance - General health status - Family history - Medical/ surgical history - Medications - Medical/ laboratory test results - Premorbid functional activity level
