Balint's syndrome is well described in adults, but not in children. It is caused by bilateral posterior parietal lobe damage and comprises a triad of simultanagnosia (inability to simultaneously see more than a small number of items), optic ataxia (impaired visual guidance of movement of the limbs and body), and apraxia of gaze (inability to volitionally direct gaze despite the requisite motor substrate) often associated with homonymous lower visual field loss. We, here, describe five children (four males, one female; mean age 7...

INTRODUCTION: Children with disabilities (other than visual impairment) are at a higher risk of visual impairment as compared to normal population. Majority of the ocular disorders, like refractive errors and strabismus, are easily treatable. As these children depend on their visual inputs for social and academic activities, an early detection and prompt treatment of even a minor visual problem is of utmost importance for them. AIM: To assess the visual function and ocular status of children with disabilities other than visual impairment and to identify the preventable and treatable causes of visual impairment...

It has been assumed that cognitive disorder and visual-spatial disturbance in multiple system atrophy of the predominantly cerebellar type (MSA-C) are attributable to degradation of cerebellar function. The purpose of this study was to use diffusion tensor imaging (DTI) tractography to determine if patients with MSA-C characterized in part by visual-spatial disorders and cognitive disorders have changes of the structural connectivity network of nerve fibers, and to further describe the structural connectivity network...

: Craniopharyngioma is a rare, benign central nervous system tumor, which may be a source of multiple complications, from endocrinology to vision, neurology and neurocognitive functions. This morbidity can lead to reduced participation in life activities, as described in the International Classification of Functioning, Disability, and Health. The primary objective of this study was to measure participation in life activities in a population of children and young adults affected by childhood craniopharyngioma, using the LIFE-H questionnaire (Assessment of Life Habits), validated as a social participation measurement tool in various pediatric disabilities...

PURPOSE: Posterior fossa arachnoid cysts (PFAC) are mostly considered as benign lesions of the cerebellum. Although many studies have shown the major role of the cerebellum in modulating movement, language, cognition, and social interaction, there are few studies on the cognitive impact and surgical decompression of PFAC. METHODS: We present the cases of two brothers successively diagnosed with PFAC and neuropsychological delay. After multidisciplinary discussion with the boys' parents, it was decided to drain these lesions...

Prospective clinical studies support a link between psychological stress and multiple sclerosis (MS) disease severity, and peripheral stress systems are frequently dysregulated in MS patients. However, the exact link between neurobiological stress systems and MS symptoms is unknown. To evaluate the link between neural stress responses and disease parameters, we used an arterial-spin-labeling functional MRI stress paradigm in 36 MS patients and 21 healthy controls. Specifically, we measured brain activity during a mental arithmetic paradigm with performance-adaptive task frequency and performance feedback and related this activity to disease parameters...

BACKGROUND: Refractive errors, strabismus, nystagmus, amblyopia, and cortical visual impairment are observed in 50 to 90 % of patients with cerebral palsy. Ocular abnormalities are known to differ according to cerebral palsy type, and spastic type has been reported to be more likely to be associated with ocular defects than the athetoid and ataxic types. METHODS: A retrospective review of medical records was performed on 105 consecutive children with spastic type of cerebral palsy who underwent ophthalmologic examination between July 2003 and March 2006...

Danon disease, an X-linked multisystemic disorder, is due to deficiency of Lysosome-Associated Membrane Protein 2 (LAMP2). It is usually characterized by hypertrophic cardiomyopathy, mental retardation and skeletal myopathy, sometimes also with atypical features. A 20-year-old man with cognitive impairment was admitted to the Emergency Room because of a sudden chest pain. ECG showed Wolff-Parkinson-White syndrome; echocardiography revealed hypertrophic cardiomyopathy, and, shortly after, he experienced a cardiac arrest followed by an occipital ischemic stroke...

Pituitary adenoma apoplexy is a well-known clinical syndrome induced by insulin infusion, cardiac surgery, trauma, and hypothalamic releasing factors. Pituitary apoplexy can cause secondary cerebral infarct and internal carotid artery occlusion. With blockade of tumor perfusion, apoplexy triggers a sudden onset of headache, visual impairment, cranial nerve palsy, disturbances of consciousness, eyelid ptosis, and hemiparesis. However, pituitary adenoma cells with high metabolic demand cannot survive with deficient blood supply and glucose concentrations...

As the interest in the neuroprotective possibilities of docosahexaenoic acid (DHA) for brain injury has grown in the recent years, we aimed to investigate the long-term effects of this fatty acid in an experimental model of perinatal hypoxia-ischemia in rats. To this end, motor activity, aspects of learning, and memory function and anxiety, as well as corticofugal connections visualized by using tracer injections, were evaluated at adulthood. We found that in the hours immediately following the insult, DHA maintained mitochondrial inner membrane integrity and transmembrane potential, as well as the integrity of synaptic processes...

PURPOSE: To investigate whether the adapted version of the Gross Motor Function Measure-88 (GMFM-88) for children with Cerebral Palsy (CP) and Cerebral Visual Impairment (CVI) results in higher scores. This is most likely to be a reflection of their gross motor function, however it may be the result of a better comprehension of the instruction of the adapted version. METHOD: The scores of the original and adapted GMFM-88 were compared in the same group of children (n=21 boys and n=16 girls), mean (SD) age 113 (30) months with CP and CVI, within a time span of two weeks...
