Stroke Flashcards
What anatomical region is affected?
- Facial loss of temperature + pain same side
- Limb + trunk loss of temperature on contralateral side
- Vestibular signs (ipisilateral)
- Ipisilateral bulbar weakness
- Autonomic dysfunction, including ipisilateral Horner’s
Lateral medullary
Lateral medullay infarct is caused by occlusion of ______ vessel
Intracranial vertebral artery
What stroke syndrome?
- Ipisilateral limb ataxia
- Ipisilateral bulbar weakness
- Contralateral loss of temperature in limbs/ trunk
- Early ipisilateral facial pain/ paraesthesia
Wallenberg syndrome
Construction/ dressing apraxia is associated with lesion to what part of the brain?
Nondominant parietal lobe
Gerstmann syndrome is associated with a lesion to what part of the brain?
Dominant (inferior) parietal lobe
What syndrome:
- Acalculia
- Finger agnosia
- Agraphia
- Right/ left confusion
Gerstmann syndrome
(Dominant, inferior parietal lesion)
Features of non-dominant parietal lesions
Dressing + construction apraxia
What lesion:
- Auditory agnosia
- Homonymous upper quandrantanopia
Non-dominant temporal lobe
What lesion:
- Homonymous upper quandrantanopia
- Wernicke’s aphsia
Dominant temporal lobe
What lesion:
- Broca’s aphsia
Dominant frontal lobe
Cerebrovascular complications of syphilis
Meningovascular syphilis
- Present with CNS infarct due to intracranial vessles being affected
Carotid endarterectomy is associated to what CN palsy
CN 12 - hypoglossal nerve
Investigations required to determine cause of cerebral infarct in acute strokes?
Carotid assessment- doppler, MRI, CT angiography
ECG: MI, arrhythmias causing thrombus formation
Echo: intracardial thrombus
Treatment of spasticity post-stroke
Dantrolene
Indications of endarterectomy in carotid stenosis for TIA/ stroke
Stenosis >70%
(<30% = medical management)
