New research suggests umbilical cord blood may help predict autism spectrum disorder. A study found a link between specific fatty acids in the blood supplied to fetuses via the umbilical cord and ASD symptoms. The presence of certain acids in the cord blood could be a breakthrough in understanding and potentially preventing ASD. The study analysed 200 children and found that one compound, a dihydroxy fatty acid, could impact the severity of ASD symptoms, with different molecules affecting various aspects of the disorder. This discovery could lead to improved interventions for children with ASD.
