opzioni binarie anna risk of autismAs parents-to-be rise in age, especially the mother, the risk of autism rises.[1] According to new research, this risk accelerates especially for mothers older than 30.1 The new study, from researcher from the Drexel University School of Public Health in Philadelphia and Karolinska Institute in Sweden, provides deeper insight into how the risk associated with autism rises with parental age, and how it varies between the age of the mother and age of the father.1

Lee, PhD, senior author of the study. “The observed differences in risk based on mothers’ and fathers’ ages point to a need to continue investigating underlying mechanisms of autism spectrum disorders that may be influenced by a mother’s age even though most recent discussion has focused on fathers’ and even grandfathers’ ages.”1
