Chagas disease (CD) is an important cause of cardiomyopathy and stroke in Brazil. Brain infarcts and atrophy seem to occur independently of cardiomyopathy severity and cognitive impairment is understudied. Objective Compare the prevalence of brain magnetic resonance imaging abnormalities between patients with or without CD; determine if inflammatory biomarkers are increased in CD; and determi...

BACKGROUND The reversed clock phenomenon results in the transposition of objects from one side to another. Its major manifestation consists in the reversal of clock numbers in clock-drawing test. It could be due to a stroke disrupting attentional cerebral network. This phenomenon usually regresses in a few days. OBJECTIVE To report a case of reversed clock phenomenon with disorders of space r...

BACKGROUND Selective serotonin reuptake inhibitors improve cognition in patients with stroke and increase the expression of brain-derived neurotrophic factor (BDNF) in the rat hippocampus. However, the effects of selective serotonin reuptake inhibitors on cognition and serum BDNF levels in patients with vascular dementia are largely unknown. We performed an open-label study to investigate the e...

PURPOSE OF THE STUDY Current hepatic encephalopathy grading tools are limited because of complexity or subjectivity. The degree of constructional apraxia could serve as a simple, objective and reproducible tool to grade encephalopathy. STUDY DESIGN In this cross-sectional study of patients with chronic liver disease, the degree of constructional apraxia was judged by their ability to copy a sta...
