Common Stroke Syndroms Flashcards
1
Q
Common stroke Syndromes
A
- Typical not universal
- Deficits produced depend on areas of the brain affected and can include sensation, speech, behavior, thought patterns and memory as well as motor deficits
2
Q
Middle Cerebral Artery Syndrome
A
- MCA
- Most common
3
Q
Typical Symptoms of MCA
A
- Contralateral upper extremity / facial weakness and sensory deficits
- Global Aphasia (if infarct is in the dominant hemisphere, usually left)
- Homonymous Hemianopia
- Loss of conjugate eye gaze
4
Q
Homonymous Hemianopia
A
- loss of the R or L half of the visual field
5
Q
Loss of conjugate eye gaze
A
- Parallel movement of the eyes
- Produces diplopia (double vision)
6
Q
Symptoms of Posterior Cerebral Artery Syndrome
A
- Contralateral Sensory Loss
- Pain
- Memory Deficits
- Homonymous hemiaopia
- Visual Agnosia
- Cortical blindness
7
Q
Visual Agnosia
A
- Inability to recognize familiar objects / people
8
Q
Cortical Blindness
A
- Acquired from occipital lobe damage
9
Q
Anterior Cerebral Artery Syndrome and Symptoms
A
- Uncommon
- Contralateral lower extremity weakness and sensory deficits
- Expressive aphasia
- Incontinence
10
Q
Vertebrobasilar Artery Syndrome and Symptoms
A
- Complete occulsion is often fatal
- Crainial nerve involvement
- Ataxia
11
Q
Crainial Nerve involvement for Vertebrobasilar Artery Syndrome
A
- Diplopia, dysarthria (difficulty controlling coordinating mm’s of speech resulting in slurred slow speech that is difficult to understand, dysphagia (difficulty swallowing) deafness, vertigo
12
Q
Ataxia
A
- lack of mm coordination during voluntary movements
13
Q
Lucunar Infarcts
A
- Usually multiple lacuna (pools) are present
- Due to occlusion of small arterioles in various locations (typically in the internal capsule)
ie: Thalamus, basal ganglia and pons - Can produce varied symptoms, depending on the areas involved
14
Q
Pusher Syndrome
A
- Seen with R CVA (L Hemisphere)
- Strong lateral leaning and weight shift toward the L side in all postions
- opposite what is normally seen - weight shift to stronger side
- Patient strongly resists passive correction
- Providing assistance with transfers is very difficult
- Increased risk of falling
- Pt leans / pushes toward the involved L side, but cannot provide adequate support on that side
- Tx should not attempt to push against the pt to correct posture (Will result in stronger push by pt)
15
Q
Typical Impairments with R CVA
A
- L Hemiplegia
- Spatial-perceptual deficits
- Impulsive, poor judgment
- Memory deficits related to performance
- Unilateral neglect
- Emotional lability
