Stroke Classification Flashcards
1
Q
What is the most commonly used stroke classification?
A
- Bamford classification of ischemic stroke
2
Q
what are stroke patients categorised using?
A
- presenting symptoms & signs
3
Q
what are the 4 different classifications?
A
- total anterior circulation infarct
- partial anterior circulation infarct
- posterior circulation infarct
- lacunar infarct
4
Q
what is TACI?
A
- total anterior circulation infarct
- large cortical stroke affecting the areas of the brain supplied by both the middle and anterior cerebral arteries
5
Q
what three symptoms need to be present for TACI?
A
- unilateral weakness (and/or sensory deficit) of the face, arm and leg
- homonymous hemianopia
- higher cerebral dysfunction (dysphasia, visuospatial disorder, decreased consciousness level)
6
Q
what is PACI?
A
- partial anterior circulation infarct
- less severe form of TACS, in which only part of the anterior circulation has been compromised
7
Q
which two of the three symptoms need to be present for PACI?
A
- unilateral weakness (and/ or sensory deficit) of the face, arm and leg
- homonymous hemianopia
- higher cerebral dysfunction (dysphasia, visuospatial disorder)
8
Q
what is POCI?
A
- posterior circulation infarct
- damage to the area of the brain supplied by the posterior circulation e.g., cerebellum, brainstem
9
Q
what one of the three needs to be present for POCI?
A
- cranial nerve palsy and contralateral motor and sensory deficit
- B/L motor or sensory deficits
- conjugate eye problems
- cerebellar dysfunction
- isolated homonymous hemianopia
10
Q
what is LACI?
A
- lacunar infarct
- subcortical stroke occurs as a consequence of small vessel disease
11
Q
what doesn’t LACI cause impairments to?
A
- no impairments of higher cerebral functions e.g., dysphasia, neglect
12
Q
what one needs to be out of the 4 for LACI?
A
- pure sensory stroke
- pure motor stroke
- sensorimotor stroke
- ataxic hemiparesis
- all >2/3 arm/ face and leg
13
Q
what problems may be present in LACS?
A
- balance problems
14
Q
what is dysphasia?
A
- impairment in the production of speech
15
Q
what are the two visuspatial disturbances?
A
- hemi neglect
- unaware of surroundings in relation to space
16
Q
what is hemi neglect?
A
- failure to report or respond to people/ objects presented to the side opposite a brain lesion
17
Q
what is homonymous hemianopia?
A
- vision loss on the same side - left or right- in both eyes
