[The impact of dysglycemia on brain function in children with type 1 diabetes mellitus].

Diabetes is a metabolic disease defined by increased blood glucose level above the references value. Insulin therapy is mandatory for all patients with type 1 diabetes melitus (T1DM). However, the insulin therapy is also the potential factor of hyperglycemia as well as hypoglycemia condition called dysglycemia. Moreover, T1DM leads to late organ changes such as retinopathy and nephropathy primarily due to diabetic angiopathy. Neuropathy is one of diabetic complications which can occur from the beginning of the disease. The pathogenesis of diabetic neuropathy, a structural and morphological abnormality, has been well described. In adults with T1DM diagnosed in childhood more frequent incidence of epilepsy, abnormal EEG and impaired cognitive functions were diagnosed. In children with type I diabetes further in depth studies are needed concerning the structural and functional damage of the central nervous system (cns). Research studies carried out in children have shown that the metabolic and morphological cns changes are the result of both hypo- and hyperglycemia.
