Autism and attention deficit hyperactivity disorder show genetic and neurobiological overlap, which may provide clues to the origin of both disorders, says Joel Nigg.
A compound that boosts inhibitory signals in the brain could treat hyperactivity and excitability in mice that model fragile X syndrome, according to a study published 8 November in Developmental Neuroscience.
HMGN1, a protein that regulates gene expression, leads to social deficits and hyperactivity when expressed at elevated levels in mice, according to a study published 9 December in the Journal of Biological Chemistry. This effect may result from HMGN1 dampening MeCP2 expression, the study suggests.
A subset of people with autism have genetic and biochemical abnormalities in a sleep-related enzyme, according to research presented Friday at a satellite conference of the Society for Neuroscience annual meeting in Washington, D.C.
Genetic variants in two autism-associated genes have been linked to repetitive behavior and hyperactivity, two common symptoms of the disorder, according to two studies published in the past few months.
Infants with fragile X syndrome spend more time looking at a toy before switching their attention elsewhere than do healthy controls, according to a study published 1 July in the Journal of Autism and Developmental Disorders.
