Children who are exposed to agricultural pesticides while developing in the womb are six times more likely to develop autism. The first eight weeks after conception seem to be the most vulnerable time, and the risk increases dramatically if, during that time, their mothers were living close to farms that had used pesticides, and especially dicifol and endosulfan. Researchers from the National Institutes of Environmental Health Sciences in the USA made the connection after they studied the records of 465 children with auti......

Aug. 23, 2007 — In the first study of its kind, researchers have discovered that in autistic individuals, connections between brain cells may be deficient within single regions, and not just between regions, as was previously believed. Tony Wilson, Ph.D., lead researcher and assistant professor of neurology at Wake Forest University School of Medicine, said he hopes this study will eventually lead to earlier diagnosis and more targeted medications for autism. Using magnetoencephalography (MEG) brain imaging technology to measure brain electrical activity, the researchers administered a test called the 40 hertz (cycles per second) auditory steady-state response test. The test measures electromagnetic wave cycles and indicates brain cell discharges at the 40 hertz frequency. "This test measures the brain's capacity to mimic what it's hearing. A healthy brain's cells will fire back at 40 hertz," said Wilson.
The Autism Program at Yale is an interdisciplinary group of clinicians and scholars dedicated to providing comprehensive clinical services to children with autism spectrum disorders and their families. We are also one of the leading research centers in the world and were recently recognized as a National Institutes of Health Autism Center of Excellence. Our program involves infants, toddlers, pre-school, and school-age children, as well as young adults (18-21 years) with autism and related disorders and integrates highly experienced professionals from the fields of clinical psychology, neuropsychology and neuroimaging, child psychiatry, speech-language pathology, social work, genetics and the biological sciences, as well as psychopharmacology and psychiatric nursing. Our clinical and research activities are located in the Child Study Center at Yale University, School of Medicine in New Haven, Connecticut.
