OBJECTIVE: This study assessed whether a single diabetic ketoacidosis (DKA) episode is associated with cognitive declines in children with newly diagnosed type 1 diabetes and whether the same is true in children who had previously been diagnosed after accounting for variations in glycemic control and other relevant factors.
RESEARCH DESIGN AND METHODS: We prospectively enrolled 758 children, 6-18 years old, who presented with DKA in a randomized multisite clinical trial evaluating intravenous fluid protocols for DKA treatment. DKA was moderate/severe in 430 children and mild in 328 children. A total of 392 children with DKA had new onset of type 1 diabetes, and the rest were previously diagnosed. Neurocognitive assessment occurred 2-6 months after the DKA episode. A comparison group of 376 children with type 1 diabetes, but no DKA exposure, was also enrolled.
RESULTS: Among all patients, moderate/severe DKA was associated with lower intelligence quotient (IQ) (β = -0.12, < 0.001), item-color recall (β = -0.08, = 0.010), and forward digit span (β = -0.06, = 0.04). Among newly diagnosed patients, moderate/severe DKA was associated with lower item-color recall (β = -0.08, = 0.04). Among previously diagnosed patients, repeated DKA exposure and higher HbA were independently associated with lower IQ (β = -0.10 and β = -0.09, respectively, < 0.01) and higher HbA was associated with lower item-color recall (β = -0.10, = 0.007) after hypoglycemia, diabetes duration, and socioeconomic status were accounted for.
CONCLUSIONS: A single DKA episode is associated with subtle memory declines soon after type 1 diabetes diagnosis. Sizable IQ declines are detectable in children with known diabetes, suggesting that DKA effects may be exacerbated in children with chronic exposure to hyperglycemia.
