Children with too many or too few copies of certain genes are more likely to have autism, as are children born to women who battled a severe infection while pregnant. These seemingly disparate risk factors may work together to worsen autism symptoms.
Within months of being diagnosed with autism, preschoolers with the disorder may already be on distinct trajectories, according to a study published 28 January in JAMA Psychiatry. The findings suggest that the severity of autism symptoms does not track with the ability to function in daily life.
Engineers and clinicians are collaborating to create wearable sensors that can track the behaviors of people with autism.
Many toddlers with autism display so few abnormal behaviors during short doctor visits that they may evade the diagnostic eye of even expert clinicians.
Fetal mice that have too many neurons grow to show social deficits and repetitive behaviors. The finding, reported 11 December in Cell Reports, debuts a mouse model of autism that’s based on a biological abnormality seen in some people with the disorder.
Names such as autism, schizophrenia and intellectual disability are ‘umbrella’ terms that muddy the search for the true cause of an individual’s symptoms, says Eric London. He plans to come up with an alternative diagnostic scheme for developmental disabilities over the next two years.
Individuals with autism may become overwhelmed by rapidly changing circumstances, particularly if they need to use social cues to navigate those changes.
Risperidone can ease irritability in people with autism, but has no effect on repetitive behaviors, social impairments or communication deficits, according to a study published 19 November.
A new study points to a possible link between inflammation in the womb, brain overgrowth and the behavioral impairments seen in autism.
A treatment that targets the genetic defect in tuberous sclerosis prevents autism-like symptoms in mice at 6 weeks of age — the mouse equivalent of adolescence. Researchers presented the unpublished results yesterday at the 2014 Society for Neuroscience annual meeting in Washington, D.C.
