We analysed the reading abilities and processing of 21 children with Duchenne muscular dystrophy (DMD), 11 matched children suffering from spinal muscular atrophy (SMA) and 42 children receiving normal education. The principal result observed was that the DMD children exhibited a reading age which was significantly lower than the SMA children compared with(More)
In order to clarify cognitive functions in Duchenne muscular dystrophy (DMD), we performed a new controlled neuropsychological study. IQ (WISC-R), verbal skills (fluency, confrontation naming and syntax comprehension) and memory abilities (BEM) were studied in two matched groups; 24 DMD children and 17 spinal muscular atrophy (SMA) children aged 12-16 yr. A(More)
Two hundred and thirty-six adult epileptic outpatients were classified twice: firstly according to the time of seizures reported by the patient or his family in diurnal, nocturnal, awaking and diffuse epilepsies (Es) and secondly according to the sensitivity to sleep or waking of the interictal paroxysmal activities (PA) observed during a polysomnographic(More)
In 242 neurologically symptomless patients with at least one non-occlusive carotid stenosis on ultrasonography (continuous wave doppler and echotomography-B mode imaging) 171 carotids showed 0-50% stenosis, 150 showed 50-75% stenosis, and 78 showed more than 75% stenosis. The mean follow-up was 29.4 months, with stroke and death as end points. Of the 56(More)
The authors report the retrospective study of a medico-surgical series of 161 patients with intracranial meningiomas, diagnosed over a period of 9 years, with a follow-up period varying from 18 months to 9 years. Out of 185 cases studied, 24 were excluded because information or perspective were inadequate. Of the 161 cases retained, 133 (82.6%) were given(More)
BACKGROUND AND PURPOSE Three-dimensional time-of-flight (TOF) MR angiography has been evaluated in the follow-up of intracranial aneurysms treated with Guglielmi detachable coils (GDCs) with good results. Some of the studies used contrast material in addition to the 3D TOF MR technique and others did not. We assessed the usefulness of contrast material with(More)
The objective of this research was to identify the psychological and physiological variables that differentiate persons reporting masticatory muscle pain (MMP) from normal controls (NC). This study examined the characteristics of 35 MMP patients in comparison to 35 age-, sex-, and weight-matched NCs. All subjects completed a series of standardized(More)
Few physiological studies have been performed in PSP. We studied: sleep abnormalities in 36 h polygraphic recordings; changes of PEV after pattern-reversal stimulation, of BAER and of short latency SEP after stimulation of the median nerve. The population was for the 1st group: 18 patients with full typical symptomatology, for the 2nd group: 7 patients with(More)
We studied the morphometric MRI findings and their correlation with cognitive functions in a population of 10 young adults shunted for congenital hydrocephalus related to spina bifida. Morphometric MRI analysis included measurement of the ventricular dilatation index, frontal and occipital parenchymal thickness and the size of the corpus callosum. The(More)
As opposed to genetics, dealing with gene expressions by direct DNA sequence modifications, the term epigenetics applies to all the external influences that target the chromatin structure of cells with impact on gene expression unrelated to the sequence coding of DNA itself. In normal cells, epigenetics modulates gene expression through all development(More)
