stroke Flashcards
features
motor weakness speech problems - dysphasia swallowing problems - dysphagia homonoymous hemianopia balance problems
features of cerebral hemisphere infarcts
contralateral hemiplegia
contralaterol sensory loss
homonymous hemianopia
dysphagia
features of brainstem infarction
quadriplegia
locked in syndrome
lacunar infarcs
small infarcts around basal ganglia, internal capsule, thalamus and pons
lacunar infarct features
pure motor, pure sensoyr, mixed motor + sensory or ataxia
total anterior circulation infarct - what vessel
involves middle and anterior cerebral arteries
total anterior circulation infarct - criteria
3/3 of
- unilateral hemiparesis and/or hemisensory loss
- homonymous hemianopia
- higher cognitive dysfunctio ne.g. dysphasia
partial anterior circulation infarct - which vessels
involves smaller arteries of anterior circulation
e.g. upper or lower divisions middle cerebral artery
partial anterior circulation infarct - criteria
2/3 of
- unilateral hemiparesis and/or hemisensory loss
- homonymous hemianopia
- higher cogntive funciton decline e.g. dysphasia
Lacunar Infarcts - which vessels
perforating arteries around internal capsule, thalamus and basal ganglia
lacunar infarcts - criteria
1 of
- unilateral weakness (and/or sensory deficit)
- pure sensory stroke
- ataxic hemiparesis
posterior circulation infarcts - which vessel
involves vertebrobasilar arteries
posterior circulation infarcts - criteria
1 of
- cerebellar or brainstem syndromes
- loss consciousness
- isolated homonymous hemianopia
haemorrhagic stroke - more likely to have
decrease level of consciousness
headache
N&V
seizure
Ix
need emergency neuroimaging
CT
MRI
