Lateral pontine syndrome, also known as Marie-Foix syndrome or Marie-Foix-Alajouanine syndrome [1] is one of the brainstem stroke syndromes of the lateral aspect of the pons. A lateral pontine syndrome is a lesion which is similar to the lateral medullary syndrome , but because it occurs in the pons , it also involves the cranial nerve nuclei ...
Parisian journalist Jean-Dominique Bauby had a stroke in December 1995, and, when he awoke 20 days later, he found his body was almost completely paralyzed; he could control only his left eyelid. By blinking this eye, he slowly dictated one alphabetic character at a time and, in so doing, was able over a great deal of time to write his memoir ...
Approximately 10% of these silent strokes are silent lacunar infarctions. While dubbed "silent" due to the immediate lack of classic stroke symptoms, SLIs can cause damage to the surrounding brain tissue and can affect various aspects of a person's mood, personality, and cognitive functioning. A SLI or any type of silent stroke places an ...
Medial inferior pontine syndrome is a condition associated with a contralateral hemiplegia. [ citation needed ] "Medial inferior pontine syndrome" has been described as equivalent to Foville's syndrome .
It is most frequently caused by lesions such as vascular disease and tumors involving the dorsal pons. Structures affected by the lesion are the dorsal pons (pontine tegmentum) which comprises paramedian pontine reticular formation (PPRF), nuclei of cranial nerves VI and VII , corticospinal tract , medial lemniscus , and the medial longitudinal ...
Pontine lesions can typically be distinguished from supranuclear lesions in the frontal lobe based on clinical neurologic findings. Gaze palsies secondary to frontal lobe lesions can be temporarily relieved with rapid, passive horizontal head rotation, which also directly stimulates the sixth nerve nucleus through the vestibuloocular reflex .
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]
