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]
Symptoms and signs [ edit ] The symptoms of brain stem tumors vary greatly and can include ataxia , cranial nerve palsy, headaches , problems with speech and swallowing, hearing loss, weakness, hemiparesis , vision abnormalities, ptosis , and behavioral changes.
Bickerstaff brainstem encephalitis is a rare inflammatory disorder of the central nervous system, [3] first described by Edwin Bickerstaff in 1951. [ 4 ] [ 5 ] It may also affect the peripheral nervous system , and has features in common with both Miller Fisher syndrome and Guillain–Barré syndrome .
Increased pressure on the brainstem can result in dysfunction of the centers in the brain responsible for controlling respiratory and cardiac function. The most common signs are intractable headache, head tilt, and neck stiffness due to tonsillar impaction. The level of consciousness may decrease and also give rise to flaccid paralysis.
Migraine with brainstem aura A migraine with brainstem aura is a rare subtype of migraine, formerly known as basilar-type migraine, which occurs with additional neurological symptoms such as ...
Histopathology of a brainstem glioma. A brainstem glioma is a cancerous glioma tumor in the brainstem. Around 75% are diagnosed in children and young adults under the age of twenty, but have been known to affect older adults as well. [1] Brainstem gliomas start in the brain or spinal cord tissue and typically spread throughout the nervous ...
In children, the most common cause is a stroke of the ventral pons. [9]Unlike persistent vegetative state, in which the upper portions of the brain are damaged and the lower portions are spared, locked-in syndrome is essentially the opposite, caused by damage to specific portions of the lower brain and brainstem, with no damage to the upper brain.
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.
