A study showed a small link between thyroid functioning and CDS symptoms suggesting that thyroid dysfunction is not the cause of CDS. High rates of CDS were observed in children who had prenatal alcohol exposure and in survivors of acute lymphoblastic leukemia, where they were associated with cognitive late effects. [41] [42] [43]
