The aim of this study was to determine whether perceptual-motor competence in school-age children with Down syndrome was generally delayed or varied as a function of type of action. Twenty-two children with Down syndrome (13 males, 9 females), aged between 4.5 and 14 years were assessed on two standardized tests, the Movement Assessment Battery for Children(More)
PURPOSE Mechanisms inducing continuous spike-wave during slow sleep (CSWS) in encephalopathy with electrical status epilepticus during sleep are still unclear. Recently, some sporadic cases with early thalamic injury associated with CSWS have been reported. The aim of the study was to investigate in a population of patients with an early thalamic injury the(More)
The aim of this retrospective study was to establish the presence and severity of cerebral visual impairment in preterm infants with PVL. We also wished to establish whether abnormalities of visual function are related to brain MRI findings and more specifically not only to the involvement of optic radiations and occipital cortex but also to changes in the(More)
Migraine is the most common type of chronic episodic headache. Several population-based family studies have suggested a strong genetic predisposition to migraine, especially migraine with aura (MA). Although several susceptibility loci have been identified, none of the numerous studies performed to date have led to the identification of a gene responsible(More)
Seizures are a frequent sign of cerebral supratentorial tumors in children, especially when the location of the neoplasm is the temporal lobe. We report a series of 37 pediatric patients with temporal epileptogenic tumors. They represent 80.4% of children affected by temporal neoplasms, confirming the high incidence of seizures when neoplasms are located in(More)
We performed a long-term follow-up of 10 patients with hemimegalencephaly and refractory epilepsy, after having treated them with hemispherectomy. Before surgery, 9 patients presented with delayed motor and cognitive development. Surgery was performed between age 5 months and 4 years and 8 months; the mean postsurgical follow-up was 5 years and 2 months.(More)
Children with a deficiency of laminin alpha 2 chain generally show an involvement of skeletal muscles, cerebral white matter and peripheral nerves. Among these patients, however, there is increasing evidence of molecular and phenotype heterogeneity. We report a 19-year-old girl with distal weakness, mental retardation and refractory epilepsy in whom(More)
OBJECTIVES The objectives of this study were to (1) assess visual function in low-risk preterm infants at 35 and 40 weeks' postmenstrual age, (2) compare preterm visual abilities at term-equivalent age with term-born infants, and (3) evaluate effects of preterm extrauterine life on early visual function. METHODS Visual function was assessed by using a(More)
PURPOSE The aim of the study was to perform a detailed assessment of cognitive abilities and behaviour in a series of epileptic patients with Dravet syndrome (DS) in order to establish a possible cerebellar-like pattern. METHODS Nine children with DS without major behavioural disturbances and with cognitive abilities compatible with the assessment of(More)
Biopsies from patients with congenital hypomyelination polyneuropathy (Group I) and with late infantile (Group II) and juvenile (Group III) forms of hereditary motor and sensory neuropathy (HMSN) type III were compared, using morphometric methods and ultrastructural analysis. In congenital polyneuropathies (Group I), myelin sheaths were practically absent(More)
