The authors examined the contribution of working memory performance to subjective cognitive complaints in HIV infection beyond the influence of depressive symptoms. Thirty-six adults with HIV infection were administered neuropsychological (NP) tests of working memory, complex psychomotor efficiency, verbal learning, delayed recall, and questionnaires measuring depressive symptoms and cognitive ...

We report a female patient with a 46,XX,der(8)t(1;8)(q42.1;p23.3) karyotype who had a mild phenotype characterised by a few subtle dysmorphic features and mild developmental retardation, probably resulting from trisomy 1q42-->qter. The deletion on the short arm of the chromosome 8 appeared to be confined to the distal chromosomal segment.

1. The effects of perinatal malnutrition on behavioural development and adult shuttle-box avoidance performance were studied in Swiss white mice. 2. Mice were malnourished (a) from the 7th day of gestation until birth, (b) from birth until weaning, or (c) during both gestation and the sucking period. 3. Pups born of protein-restricted mothers had reduced birth weights, retarded development and ...

BACKGROUND Children with developmental delay (DD) have a variety of problems in developmental functions. The purposes of this study were to analyze the underlying diseases and risk factors in children with different functional delays. METHODS We collected data on 1048 children who underwent assessments of developmental function, related diseases, and risk factors. All children were classified...

The N-methyl-d-aspartate receptor (NMDAR), a ligand-gated ionotropic glutamate receptor, plays important roles in normal brain development and a wide range of neurologic disorders, including epilepsy. Here, we evaluate for the first time the functional properties of a de novo GRIN2A missense mutation (p.M817V) in the pre-M4 linker in a child with profound global developmental delay and refracto...
