Laramie, WY – A dramatic rise in the number of children diagnosed with autism has some Wyoming doctors reaching out to help. Doctor Diane Edwards of Casper has set up Wyoming's first-ever free autism screenings this month. She held her first session in Cheyenne on Friday and will hold more in Sheridan and Casper later this month. She says the incidence of autism nationwide has now risen to one in 150 babies - a figure she finds alarming. But she says early therapies can make a huge difference in an autistic child's life. Children with autism often display differences in communication, play, and socialization. Edwards recommends screening for children who display this kind of behavior, and all children between the ages 18 and 36 months.
