Claude's syndrome is a form of brainstem stroke syndrome characterized by the presence of an ipsilateral oculomotor nerve palsy, contralateral hemiparesis, contralateral ataxia, and contralateral hemiplegia of the lower face, tongue, and shoulder. Claude's syndrome affects oculomotor nerve, red nucleus and brachium conjunctivum. [1]
Weber's syndrome, also known as midbrain stroke syndrome or superior alternating hemiplegia, is a form of stroke that affects the medial portion of the midbrain. It involves oculomotor fascicles in the interpeduncular cisterns and cerebral peduncle so it characterizes the presence of an ipsilateral lower motor neuron type oculomotor nerve palsy and contralateral hemiparesis or hemiplegia.
Alternating hemiplegia (also known as crossed hemiplegia) is a form of hemiplegia that has an ipsilateral cranial nerve palsies and contralateral hemiplegia or hemiparesis of extremities of the body. The disorder is characterized by recurrent episodes of paralysis on one side of the body. [ 1 ]
Lateral medullary syndrome is the most common form of posterior ischemic stroke syndrome. It is estimated that there are around 600,000 new cases of this syndrome in the United States alone. [5] [outdated statistic] Those at the overall highest risk for lateral medullary syndrome are men at an average age of 55.06.
Hemiagnosia, hemineglect, unilateral neglect, spatial neglect, contralateral neglect, unilateral visual inattention, [1] hemi-inattention, [1] neglect syndrome, one-side neglect, [2] or contralateral hemispatialagnosia: Hemispatial neglect is most frequently associated with a lesion of the right parietal lobe (in yellow, at top).

(Medial medullary syndrome can affect structures in lower left: especially #5, #6, #8.) Specialty: Neurology Diagnostic method: Ipsilateral signs and symptoms - flaccid (lmn) paralysis and atrophy of one half of tongue (hypoglossal nerve) Contralateral signs and symptoms- spastic (umn) paralysis of trunk and limbs (contralateral corticospinal ...
Pure sensory stroke: contralateral thalamus , internal capsule, corona radiata, midbrain Marked by numbness (loss of sensation) on one side of the body; can later develop tingling, pain, burning, or another unpleasant sensation on one side of the body. Mixed sensorimotor stroke: thalamus and adjacent posterior internal capsule, lateral pons
Symptoms of a brainstem stroke frequently include sudden vertigo and ataxia, with or without weakness. Brainstem stroke can also cause diplopia, slurred speech and decreased level of consciousness. A more serious outcome is locked-in syndrome. [citation needed]
