Diabetic ketoacidosis (DKA), a serious but common complication of type 1 diabetes, is linked to lower IQ scores and worse memory in children with type 1 diabetes, according to a study led by UC Davis Health researchers. The study published Sept. 22 in Diabetes Care is also the first large-scale work to differentiate between DKA’s impact on children with a new diagnosis and children with a previous diagnosis of type 1 diabetes.
