    Amyloid-beta, the small protein that forms plaques in the brains of people with Alzheimer’s disease, is more prevalent in postmortem brains from individuals with autism than in those from controls, according to a study published 2 May in PLoS One.

    Repetitive behaviors are often motivated by anxiety when children with autism and intellectual disability transition from one task to the next, but they are linked to a desire for attention when the children have free time, according to a study published in May in the Journal of Applied Research in Intellectual Disabilities.

    Men with a common autism-linked variant of CD38, a gene that regulates levels of the ‘trust hormone’ oxytocin, benefit more from the hormone than do those with other variants, according to a study published in the May issue of Neuropsychopharmacology.
