SUMMARY: The corpus callosum (CC) includes the majority of fibers linking the two brain hemispheres. Several cross sectional studies showed an association between callosal atrophy and malfunction and neurodegenerative diseases, which may play a role in their pathological manifestations. As a result, the ...
Fetal akinesia deformation sequence (FADS), or Pena-Shokeir phenotype is a constellation of deformational changes resulting from decreased or absent fetal movement, and include arthrogryposis, and craniofacial and central nervous system anomalies. We report an autopsy case of a 36-6/7week female neonate ...
ABSTRACT Aims: To investigate hereditary spastic paraplegia (HSP) in a pediatric Brazilian sample. Methods: Epidemiological, clinical, radiological and laboratory data were analyzed in 35 patients. Results: Simple HSP (HSP-S) was detected in 12 patients, and complicated HSP (HSP-C) was detected in 23 ...

Abstract Introduction: Bipolar disorder (BD) is a debilitating mood condition that affects approximately 1.3% of people worldwide, although some studies report up to 3.9% lifetime prevalence and 4-6% in adults when broad diagnostic criteria are applied. Objective: To compare differences in total white ...

SUMMARY: The aim of this study was to identify the values of corpus callosum sections and ventricles in Dementia and healthy geriatric subjects using magnetic resonance imaging (MRI) and to establish both gender differences and differences between groups. The MRI results of 163 geriatric subjects (81 hea...
ABSTRACT Objective To evaluate the role of the involvement of white matter tracts in huntingtin gene mutation patients as a potential biomarker of the progression of the disease. Methods We evaluated 34 participants (11 symptomatic huntingtin gene mutation, 12 presymptomatic huntingtin gene mutation,...
Objective: To evaluate transcallosal changes after a local ischemic injury in rats by using the monoclonal marker anti-NeuN (Mouse anti-neuronal nuclei). Methods: Twenty eight adult, male, Wistar rats were subjected to focal injury in the right hemisphere. The technique used was the experimental model of...

Ratas malnutridas prenatalmente con una dieta isocalórica y baja en proteínas, presentaron un menor diámetro axonal promedio en el esplenio callosal que los animales control, tanto de las fibras mielínicas como amielínicas. También se observó una mayor densidad axonal promedio, con respecto a los ...
