Gastrointestinal Problems In Autistic Children May Be Due To Gut Bacteria

The underlying reason autism is often associated with gastrointestinal problems is an unknown, but new results to be published in the online journal mBio® on January 10 reveal that the guts of autistic children differ from other children in at least one important way: many children with autism harbor a type of bacteria in their guts that non-autistic children do not. The study was conducted by Brent Williams and colleagues at the Mailman School of Public Health at Columbia University.

When Teens With Autism Want To Drive

In the first study to investigate driving as it relates to teens with a high-functioning autism disorder (HFASD), child development and teen driving experts at The Children's Hospital of Philadelphia's Center for Child Injury Prevention Studies found that two-thirds of teenagers with a high-functioning autism spectrum disorder (HFASD) who are of legal driving age in their state are currently driving or plan to drive.

The study is published this month in the Journal of Developmental and Behavioral Pediatrics.

A HFASD is characterized by subtle impairments in social interaction, communication, motor skills and coordination and by a difficulty in regulating emotions. Many of these capabilities come into play when driving.

Possible Link Between Autism, Abnormal Immune System Characteristics And Novel Protein Fragment

Immune system abnormalities that mimic those seen with autism spectrum disorders have been linked to the amyloid precursor protein (APP), reports a research team from the University of South Florida's Department of Psychiatry and the Silver Child Development Center.

The study, conducted with mouse models of autism, suggests that elevated levels of an APP fragment circulating in the blood could explain the aberrations in immune cell populations and function - both observed in some autism patients. The findings were recently published online in the Journal of the Federation of American Societies for Experimental Biology.
