The outlook for someone with lateral medullary syndrome depends upon the size and location of the area of the brain stem damaged by the stroke. [2] Some individuals may see a decrease in their symptoms within weeks or months, while others may be left with significant neurological disabilities for years after the initial symptoms appear. [4]
Medial medullary syndrome, also known as inferior alternating syndrome, hypoglossal alternating hemiplegia, lower alternating hemiplegia, [1] or Dejerine syndrome, [2] is a type of alternating hemiplegia characterized by a set of clinical features resulting from occlusion of the anterior spinal artery.
Although medial pontine syndrome has many similarities to medial medullary syndrome, because it is located higher up the brainstem in the pons, it affects a different set of cranial nuclei. [ citation needed ]
The rare [3] disorder is caused by damage to a part of the brain (medullobulbar transitional area) which causes a variety of neurological symptoms, some of which affect only one side of the body. Symptoms include ipsilateral (same side) cerebellar ataxia , sensory deficits of the face, and Horner's syndrome , along with weakness and loss of ...
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.
Cerebral infarction, also known as an ischemic stroke, is the pathologic process that results in an area of necrotic tissue in the brain (cerebral infarct). [1] In mid to high income countries, a stroke is the main reason for disability among people and the 2nd cause of death. [ 2 ]
It is one of the three main arteries that supply blood to the cerebellum, a part of the brain. Blockage of the posterior inferior cerebellar artery can result in a type of stroke called lateral medullary syndrome .
Hyperextension of the neck can pull and tear the pyramids, leading to a variety of symptoms such as weakness in all four limbs, difficulty swallowing, and difficulty speaking. A bilateral infarction in the pyramids of the medulla can result in motor quadriplegia. This is rare, however, as there have only been four cases of this reported.
