Week 1 - Stroke Flashcards
What are the primary sensori-motor deficits? 4
Strength
Co-ordination
Sensation
Spasticity
What are the primary non-motor deficits? 7
vision
speech/language (dysphasia, aphasia, dysarthria)
Perceptual function (neglect, agnosia)
Cognitive function (problem solving, motiviation, attention, memory)
Apraxia/dyspraxia
Behaviour
Emotion (lability, depression, anxiety)
What are the seconday sensori-motor deficits? 8
Muscle length Muscle strength (different to primary) Fitness Learned non-use Compensatory behaviours Swelling Shoulder subluxation Tissue damage
What are the secondary non-motor deficits? 2
Depression
Fatigue
Describe the anterior circulation.
Carotid arteries
Most of the hemispheres and the cortical deep white matter.
Describe the poster circulation
Vertebrobasilar system
Brain stem, cerebellum and occiputal lobe
Which deficits might you see in an anterior circulation stroke?
All of them: Strength Co-ordination Sensation Spasticity
Vision Speech Perception Cognitive Apraxia Behaviour Emotion
What deficits might you see in a posterior circulation stroke?
All the sensori-motor: Strength Coordination Sensation Spasticity
And vision
But not the personality/cognitive ones
What functions are covered by the left vs the right hemisphere?
Left (dominant)
Speech
Analytical functions
Right
Spatial awareness
Attention
What would you see in a left anterior stroke?
Everything but perceptual problems (attention is on the R side)
What would you see in a right anterior stroke?
Everything but language and apraxia.
Describe the Bamford Classification of Stroke
TACS
PACS
LACS
POCS
THe S stands for syndrome, but can become I for infarct and H for haemorrhage.
What are the three signs of PACS (must have all three)
Hemiplegia (+/- sensory loss)
Hemianopia
Cortical signs
What are the signs of PACS?
2 out of 3 of:
Hemplegia
Hemianopia
Cortical signs
OR
Isolated cortical dysfunction
OR
Pure sensory/motor but less severe than lacunar.
WHat are the signs of a LACS?
Hemiplegia of at least 2/3rds of arm/face/leg but NO cortical signs.
