  ANSWER: A Basilar artery stroke causes quadriplegia, sensory loss, and cranial nerve involvement; patients may present with coma or locked-in syndrome. Wallenberg syndrome or lateral medullary syndrome causes an ipsilateral weakness of the palate and vocal cords, ipsilateral ataxia, ipsilateral Horner syndrome, and ipsilateral loss of facial pain and temperature but contralateral loss of body pain and temperature sensation. There is no limb weakness in Wallenberg syndrome. Anterior cerebral stroke causes unilateral leg weakness and sensory loss. Posterior cerebral artery stroke causes an occipital stroke and a homonymous hemianopsia. Middle cerebral artery stroke causes hemiplegia or hemiparesis greater in the arm than the leg, aphasia, unilateral sensory loss, and eyes that deviate to the side of the hemispheric lesion. Patients with lacunar infarcts may present with different syndromes, such as dysarthria and mild hemiparesis (clumsy-hand dysarthria). Lacunar infarcts represent small artery occlusions; hypertension and diabetes are risk factors for these infarcts. Patients in a vegetative state from diffuse cortical damage have spontaneous eye opening and movement without evidence of awareness.

  LESION : Pons, medulla, lower midbrain,
corticospinal and corticobulbar
tracts, ocular cranial nerve nuclei,
paramedian pontine reticular

SYMTOMS; Preserved consciousness and
blinking, quadriplegia, loss of
voluntary facial, mouth, and
tongue movements

is a “Locked-in syndrome.”

  Good question .

late to respond.
A. Basiliar artery /ventral pons lesions--->absent motor but intact sensory + only vertical eye movement , patient can not move eyes horizontally.

  Good question .

late to respond.
A. Basiliar artery /ventral pons lesions--->absent motor but intact sensory and cognitive function,completely awrae of surroundings + only vertical eye movement or blink present , patient can not move eyes horizontally.

Vs Persistent vegetative state- loss of awareness and cognitive functions.
