Comorbidity of type 1 diabetes and depression is a serious clinical problem, as each of the chronic diseases may worsen
symptoms of the other, and thus significantly reduce the quality of life and endanger the health of patients. Shared
underlying biological and behavioral mechanisms are considered in the comorbidity of depression and type 1 diabetes.
Growing evidence of the role of sleep is emerging in both diseases. The ambiguity of terminology and blurred
distinction between clinical diagnosis of depression, subthreshold depressive symptoms and diabetes-specific distress
contributes to a great variance in estimated prevalence of depressive disorders in patients with type 1 diabetes. Further
research is needed to determine the strength of associations between depression and type 1 diabetes, and to prove observed
findings in the clinical practice.
