IL-18 and BDNF concentrations (pg/ml) in the sera of autism patients. Autistic patients were classified as severe, based on a Childhood Autism Rating Scale (CARS) score of 37 or more; mild-to-moderate disease as determined by CARS score between 32 and 37; and mild, according to CARS score below 32. An inverse relationship between IL-18 and BDNF was observed in the group of patients with severe autism
