although hydatid disease eradicated in many countries, it is still widespread in communities where agriculture is dominant. cystic hydatidosis is significant public health problem in the regions with endemic echinococcosis. the hydatid cysts tend to form mostly in the liver or lung. brain involvement is very rare. in the present report, we describe magnetic resonance imaging findings in an 18-y...

Gerstmann’s syndrome is caused by a left (dominant) inferior parietal lesion, particularly involving the angular gyrus or subjacent white matter of the left hemisphere. We describe case of an 80 year old right handed man admitted to our hospital with history of sudden onset of blurred vision. At first in neurological examination, he had left hemonymus hemianopia and characteristic features of G...

The development of hemispherectomy for glioma (mostly in adults) by Dandy (1928) and later for infantile hemiplegia by Krynauw (1950) permitted comparisons of effects of removal of either hemisphere on both the adult and young brain. Reviews of over 300 cases of hemispherectomy (e.g., White, 1961; McFie, 1961) reflect the 'functional plasticity' of the young brain. Continuing development of hig...

Patients with Alzheimer's disease vary in their ability to sustain cognitive abilities in the presence of brain pathology. A major open question is which brain mechanisms may support higher reserve capacity, i.e. relatively high cognitive performance at a given level of Alzheimer's pathology. Higher functional MRI-assessed functional connectivity of a hub in the left frontal cortex is a core ca...

BACKGROUND Functional magnetic resonance (fMRI) studies results in case of an adult patient with low grade glioma (LGG) in dominant hemisphere suggest brain plasticity process with acquisition of language functions by the non-dominant hemisphere speech regions. CASE REPORT A 36-years old right-handed woman was admitted to the Department of Neurosurgery for surgical treatment of brain tumor. A...

We report 2 patients who complained that the left half of faces appeared distorted. A 58-year-old right-handed woman explained that although the left side of the face was clearly visible, it appeared distorted “like a monster.” The left eye looked elongated toward the left ear, while the nose appeared to be bent toward the left cheek, and the mouth toward the chin. She did not have any dyslexia...

purpose: to report a case of unilateral severe visual loss and bilateral optic disc cupping secondary to brain metastasis of bronchogenic carcinoma patient and findings: a 48 year-old woman presented with severe visual loss of left eye without redness or pain or any systemic findings .clinical findings included decreased visual acuity of left eye to 4 m cf and (+3) positive marcus-gunn reflex ....

According to decades of research on affective motivation in the human brain, approach motivational states are subserved by the left hemisphere and avoidance states by the right hemisphere. Here we show that hemispheric specialization for motivation reverses with handedness. This covariation provides initial support for the Sword and Shield Hypothesis, according to which hemispheric laterality o...

Objectives: The dominant leg has always received special attention in public health practices and even in professional clinical evaluation and interventions. The aim of this research study was to methodically examine the substrate balance character of the non-dominant leg under dual task conditions and visual deprivation to increase the baseline insight for maintaining body balance and for fall...
