Researchers studied 30 autistic children ages 2 through 18, who were observed during and after a fever of 100.4 degrees Fahrenheit or higher.

More than 80 percent study participants showed some improvements in behavior and 30 percent had dramatic improvements during a fever. The observed improvements included longer concentration spans, more talking, improved eye contact, and better overall relations with adults and other children, the researchers said.

Study author Dr. Andrew Zimmerman, a pediatric neurologist at Kennedy Krieger Institute in Baltimore, said the research may lead to a treatment that would reconnect the autistic brain.
