DALLAS, April 28 (UPI) -- Autism spectrum is difficult to diagnose but early screening and intervention offer "a better chance" for timely diagnosis and treatment, a U.S. expert says.
Dr. Catherine Karni -- a psychiatrist at the University of Texas Southwestern Medical Center in Dallas and medical director of outpatient services at the Center for Pediatric Psychiatry at Children's Medical Center Dallas -- said patients often display a distinctive pattern of symptoms rather than just one.
