Alternating hemiplegia of childhood (AHC) is a rare, severe neurodevelopmental syndrome characterized by recurrent hemiplegic episodes and distinct neurological manifestations. AHC is usually a sporadic disorder and has unknown etiology. We used exome sequencing of seven patients with AHC and their unaffected parents to identify de novo nonsynonymous(More)
OBJECTIVES To examine the cross-sectional reliability and validity of the Parent Report Form of the Child Health and Illness Profile-Child Edition (CHIP-CE), a generic measure of health-related quality of life (HRQoL), in children with ADHD in the pan-European ADHD Observational Research in Europe (ADORE) study. METHODS Parents of children with ADHD (aged(More)
Alternating hemiplegia of childhood is a neurological disorder characterized by episodes of hemiplegia, various non-epileptic paroxysmal events and global neurological impairment. Characterization of the evolution and outcome into adulthood has not been sufficiently investigated. The goal of this study was to elucidate the natural history of alternating(More)
OBJECTIVE To describe the associations between a range of baseline factors (demographic, family and clinical) and parent-reported health-related quality of life (HRQoL) of children with ADHD taking part in the ADORE study. METHODS HRQoL was rated using the Parent Report Form of the Child Health and Illness Profile-Child Edition (CHIP-CE). Forward-stepwise(More)
BACKGROUND Attention-deficit/hyperactivity disorder (ADHD) in children affects every member of the family. Practical tools are needed to assess the effects of ADHD on families to better understand and address the level of stress, strain and burden that families experience. OBJECTIVE To provide the preliminary reliability, validity and factor structure of(More)
Alternating hemiplegia of childhood (AHC) is a rare disorder with diagnosis based on clinical criteria, as no laboratory, neuroradiological or genetic markers are currently available. The pathogenic mechanisms are still an enigma. Some hypotheses have been proposed such as hemiplegic migraine variant, epileptic mechanism, channelopathy and mitochondrial(More)
We examined 32 epileptics (20 female; 12 male; aged 6-73 years) who had displayed photoconvulsive reactions to flickering light in the EEG; they were examined with regard to their risks of getting epileptic seizures upon watching television (TV) under certain conditions. On a colour TV set each patient was shown a 3-min videofilm with slow- and fast-moving(More)
BACKGROUND A 17-year-old boy suffering from a severe schizophrenic disorder of the paranoid type and mental retardation did not respond to treatment with typical antipsychotics, whereas under clozapine treatment he showed a favourable response. Discontinuation of clozapine led to an acute psychotic relapse. During clozapine treatment the patient developed(More)
OBJECTIVES To describe the associations between a range of demographic, family and clinical factors and clinician-rated measures of global impairment in children with ADHD symptoms obtained at the baseline assessment in the ADHD Observational Research in Europe (ADORE) study. METHODS Global impairment was measured by clinicians using the Clinical Global(More)
Speech disabilities (articulation deficits) and language disorders--expressive (vocabulary) receptive (language comprehension) are not uncommon in children. An overview of these along with a global description of the impairment of communication as well as clinical characteristics of language developmental disorders are presented in this article. The(More)
