Stroke

• ACA = medial and superior frontal lobe and anterior parietal.
• ACA Stroke = contralateral paralysis and sensory loss of lower limb with urinary incontinence
• MCA = lateral cerebral hemisphere and temporal lobe
• MCA Stroke = contralateral paralysis and sensory loss of upper limb and face

  Dominant hemisphere = aphasia

  Non-dom = hemineglect

  Homonymous hemianopia
• Lacunar = striatum and internal capsule
• Lacunar stroke = Contralateral paralysis OR sensory loss
• PCA =occipital, i.m temporal, midbrain, thalamus and choroid plexus
• PCA Stroke = contralateral hemianopia with macular sparing

  Dominant = Alexia no agraphia

  Non-dom = agnosia (face blind)
• Basilar = Brainstem
• Basilar Stroke = locked in
• AICA Stroke = CN7 palsy = facial paralysis, decreased lacrimation, salivation and taste on anterior 2/3 tongue

  Vomiting, SNHL, nystagmus and ipsilateral horners
• PICA Stroke = Wallenberg

  Nucleus ambiguous palsy= dysphagia, hoarseness, decreased gag reflex and hiccups
• Webers = PCA branch = medial midbrain
• Webers Stroke = CN3 palsy and contralateral hemiparesis
• Total anterior circulation infarct =

  1. Contralateral paralysis
  2. Contralateral homonymous hemianopia
  3. Higher cerebellar dysfunction

  = middle and anterior cerebral infarct
• Partial anterior circulation infarct =

  2 of TACI

  Or high cerebral dysfunction alone

  Means anterior or middle cerebral artery infarct
