A rationale and a method are presented for estimating the prevalence of mental retardation in individual catchment areas. The method incorporates the adaptive behavior criterion of the AAMD definition of mental retardation and proposes prevalence rates based on chronological age and degree of impairment. Special focus is given to the population with moderate to profound mental retardation. a me...
OBJECTIVE To perform an extensive search for genomic rearrangements by microarray-based comparative genomic hybridization in patients with epilepsy. DESIGN Prospective cohort study. SETTING Epilepsy centers in Italy. PATIENTS Two hundred seventy-nine patients with unexplained epilepsy, 265 individuals with nonsyndromic mental retardation but no epilepsy, and 246 healthy control subjects w...
There is considerable and intense discussion in the field of intellectual disability/mental retardation about the construct of disability, how intellectual disability fits within the general construct of disability, and the use of the term intellectual disability (Glidden, 2006; Greenspan, 2006; MacMillan, Siperstein, & Leffert, 2006; Schalock & Luckasson, 2004; Switzky & Greenspan, 2006b). Thi...
In the past, it was common practice to relate low birthweight to prematurity. However, a number of environmental, maternal, placental, and fetal factors have been recognized as causing intrauterine growth retardation (IUGR) in babies who are small-for-gestational-age (SGA). In the more affluent societies, one-third of the low birthweight babies are SGA. Yet in communities where protein-energy m...
The rate of multiple pregnancy has dramatically increased during the past decades, along with the diffusion of assisted reproduction technology (ART). Multiple pregnancy entail an increased risk of, at times life threatening, maternal complications i.e. pre-eclampsia, eclampsia or abruptio placenta, of serious neonatal hazards, i.e. extreme prematurity or growth retardation, as well as deleteri...
In humans, mutations in the gene encoding ATRX, a chromatin remodeling protein of the sucrose-nonfermenting 2 family, cause several mental retardation disorders, including α-thalassemia X-linked mental retardation syndrome. We generated ATRX mutant mice lacking exon 2 (ATRX(ΔE2) mice), a mutation that mimics exon 2 mutations seen in human patients and associated with milder forms of retardation...
