| Question | Answer |
|---|---|
| Ataxic Hemiparesis vasculature | Paramedian branches of basilar artery, ventral territory |
| Ataxic hemiparesis neural structures | corticospinal/corticobulbar tracts (contralateral face, arm, and leg weakness, dystaria), Pontine nuclei and pontocerebellar fibers (contralateral ataxia) |
| AICA Syndrome vasculature | AICA |
| AICA Syndrome neural structures | Middle Cerebellar peduncle(ipsilateral ataxia),Vestibular nuclei(vertigo, nystagmus)Trigeminal nucelei(ipsilateral facial pain temp), spinothalamic tract (contralateral body pain and temp sensations), descending sympathetic fibers (ipsilateral Horners) |
| Weber's vasculature | Branches of PCA and Top of basilar artery |
| Weber's neural structures | Oculomotor nerve fascicles (ipsilateral CN3 palsy) |
| Claude's vasculature | Braches of the PCA and Top of basilar artery |
| Claude's neural structures | Oculomotor nerve fascicles (ipsilateral CN3 palsy), Red nucleus/superior cerebellar peduncle fibers (contralteral ataxia) |
| Medial medullary vasculature | Occlusions of paramedian branches of the anterior spinal or vertebral arteries |
| Medial medullary neural structures | Upper motor neurons (contralaters arm/leg weakness), CN12 (ipsilateral tongue weakness), Medial lemniscus (contralaeral vibration/joint positions vibrations) |
| Lateral Medullary vasculature (wallenberg's) | Thrombosis of vertebral artery (or sometimes PICA) |
| Lateral meduallary (wallenburgs) neural structures | Nucleus amibiguus (hoarsness/dysphagia), Nucleus solitarius (ipsilateral decrease in taste), inferior cerebral peduncle, vestibular nuclei, spinal trigeminal nuclei, spinalthalamic tract, descending symp fibers |
| Dysarthia hemiparesis vasculature | Paramedium branches of the basilar artery, ventral territory |
| Dysarthia hemiparesis neural structures | corticospinal and corticobulbar tracts (contralateral face, arm, leg weaknes and dysarthia) |
| Wallenberg location | lateral medulla |
| Medial Medullary syndrome location | medial medulla |
| AICA location | lateral pons |
| Dysarthria Hemiparesis location | medial pons |
| Weber's location | lateral midbrain (basis) |
| Claude's location | medial midbrain (tegmentum) |
| Syndrome mnemonic | Can Wash Dishes After Morris Wiman (Midbrain to meduall, medial lateral alternating) |
