Although accounting for 2% of body weight, brain has one of the greatest metabolic rates compared with other organs and systems. The energy metabolic consum is expended mainly in the maintenance of ionic gradient, essential to neuronal activity. Brain receives energy substrates from circulation, with interference of blood brain barrier (BBB). Glucose is the(More)
Acquired hepatocerebral degeneration (AHD) and hepatolenticular degeneration can have similar clinical presentations, but when a chronic liver disease and atypical motor findings coexist, the distinction between AHD and hepatic encephalopathy (HE) can be even more complicated. We describe three cases of AHD (two having HE) with different neuroimaging(More)
BACKGROUND Oropharyngeal dysphagia is common in individuals after stroke. Taste and temperature are used in dysphagia rehabilitation. The influence of stimuli, such as taste and temperature, on swallowing biomechanics has been investigated in both healthy individuals and in individuals with neurological disease. However, some questions still remain(More)
Cerebrovascular disease is recognized as to be associated with the highest mortality rate in Brazil. Dysphagia, speech and language disturbances are common consequences of the high incidence of stroke. Dysphagia is known to occur in at least 50% of the patients with acute stroke. The study is designed to establish the incidence of stroke in a reference(More)
[Purpose] The study aimed to characterize patients treated by rehabilitation section after establishment of an acute stroke unit. [Subjects and Methods] Medical consultation records of individuals with ischemic stroke were studied retrospectively, excluding individuals with hemorrhagic stroke, thrombolysis, previous Modified Rankin Scale ≥ 1, prior stroke,(More)
PURPOSE To determine the effect of sour flavor and cold temperature on oral transit time during swallowing. METHODS Participants were 52 subjects (28 male and 24 female) with ages between 50 and 80 years (median=66 years), after ischemic stroke involving right or left side damage and mild to moderate oropharyngeal dysphagia. Videofluoroscopy was performed(More)
OBJECTIVE To determine correlations between age and metabolic disorders in Parkinson's disease (PD) patients. METHODS This observational cross-sectional study included brief tests for dementia and the Mattis test. Signals of metabolic syndrome were evaluated. RESULTS There was no significant effect from the presence of hypertension (OR=2.36 for patients(More)
Alexander's disease (AD) is a rare neurodegenerative disorder , classified as a leukodystrophy and characterized by macrocephaly, psychomotor regression, spasticity, ataxia, and seizures 1. Neuropathologically, it is diagnosed by the presence of perivascular, periventricular, brainstem, and cerebellar eo-sinophylic intra-astrocytic cytoplasmic inclusions,(More)
PURPOSE To analyze the components of the acoustic signal of swallowing using a specific software. METHODS Fourteen healthy subjects ranging in age from 20 to 50 years (mean age 31 ± 10 years), were evaluated. Data collection consisted on the simultaneous capture of the swallowing audio with a microphone and of the swallowing videofluoroscopic image. The(More)
