cardiac electrical dysfunction in acute brain lesions

CARDIAC ELECTRICAL DYSFUNCTION IN ACUTE BRAIN LESIONS

This study briefly reviews the heart abnormalities in diverse intracranial pathologies, including strokes, spontaneous and traumatic subarachnoid hemorrhage and intracranial hemorrhage, and presents the results of a one-year prospective study of heart abnormalities in patients with moderate to severe head injuries and subarachnoid hemorrhage. Different abnormalities such as: QT -interval, T...

[Focal brain lesions and language dysfunction].

To be a neurologist, training in cognitive/behavioral neuroscience is essential. In this review article, the author tries to emphasize the localization relationship between focal brain lesions and language dysfunction, by discussing from split-brain syndromes, hemispheric asymmetry, to pure word dumbness, pure word deafness (verbal auditory agnosia), pure agraphia, and pure word blindness (pure...

Application of ultrasound in pulseless electrical activity (PEA) cardiac arrest

The effects of acute, sub-chronic and chronic psychical stress on the brain electrical activity in male rats

Introduction: Stress is a main factor influencing brain functions as revealed by the electroencephalogram (EEG) recordings. Moreover, different stress durations seemingly cause perturbations in brain waves and lead to mental disorders. This study investigates the effects of acute, sub-chronic and chronic stress on EEG in rats.  Methods: Twenty-eight Wistar adult male rats were randomly all...

Tumefactive Brain Lesions in Patients with Neuromyelitis Optica Spectrum Disorder

Background: Neuromyelitis Optica Spectrum Disorder (NMOSD) is an autoimmune neurological disorder that is characterized by optic neuritis and longitudinally-extended transverse myelitis lesions in spinal segments. Magnetic Resonance Imaging (MRI) findings are part of the diagnostic process in NMOSD patients, and abnormal lesion patterns may cause deviation from a correct diagnosis.  Clinical P...

Blood-brain barrier dysfunction in acute lead encephalopathy: a reappraisal.

Acute lead encephalopathy was induced in adult guinea pigs by administering daily oral doses of lead carbonate. During the development of the encephalopathy, the structural and functional integrity of the blood-brain barrier was evaluated with electron microscopy and tracer probes. Blood, cerebral gray matter, liver, and kidney were analyzed for lead, calcium, and magnesium content. The animals...
