Ipsilateral hypohidrosis in brain stem infarction.
BACKGROUND AND PURPOSE The brain stem is the most important autonomic processing center, but very little attention has been given to clinical manifestations of autonomic failure in brain stem stroke. Our purpose was to evaluate the prevalence, characteristics, and prognostic significance of sweating dysfunction in brain stem infarctions. METHODS We carried out a prospective study using quanti...
متن کاملBrain function in brain death, coma, vegetative state, minimally conscious state and locked-in syndrome
We review the nosological criteria and functional neuroanatomical basis for brain death, coma, vegetative state, minimally conscious state and the locked-in state. Functional neuroimaging is providing new insights into cerebral activity in patients with severe brain damage. Measurements of cerebral metabolism and brain activations in response to sensory stimuli using positron emission tomograph...
متن کاملSilent subcortical brain infarction
Introduction: The silent brain lesions detected by MRI were fairly common not only in first-ever stroke but also in normal elderly subjects. Some recent studies show the possible role of silent sub-cortical brain infarction in ischemic stroke. The aim of this study was to evaluate the frequency of silent sub-cortical brain infarction in acute first-ever ischemic stroke. Methods: In this descrip...
متن کاملLocked-in syndrome.
The locked-in syndrome is caused by an insult to the ventral pons, most commonly an infarct, haemorrhage, or trauma. The characteristics of the syndrome are quadriplegia and anarthria with preservation of consciousness. Patients retain vertical eye movement, facilitating non-verbal communication. Ten year survival rates as high as 80% have been reported. Even limited physical recovery can impro...
متن کاملRespiratory rate and pattern disturbances in acute brain stem infarction.
Respiratory rates and patterns were studied in 23 patients with acute brain stem infarction using impedance pneumography. Autopsy was obtained in six of eight fatal cases. Pontine lesions were present in all patients, with coexistent infarction of midbrain in four and of medulla in nine. Respiratory rate and pattern abnormalities observed included Cheyne-Stokes respiration, Cheynb-Stokes varian...
