Abstract

Dizziness is a common symptom in patients with diabetes mellitus; it can lead to or may be confused with presyncope or syncope. The causes of these three symptoms include various drugs, metabolic decompensation, cerebrovascular diseases, vestibular diseases, and diabetic autonomic neuropathy. Although cardiac autonomic neuropathy (CAN) in patients with diabetes is associated with increased cardiovascular morbidity and mortality, CAN might exist in a subclinical state before patients develop resting tachycardia, exercise intolerance, postural hypotension, cardiac dysfunction, and diabetic cardiomyopathy. Thus, it is important to detect CAN in the early phase. This article aimed to review the pathogenesis, manifestations, diagnosis, and treatment of diabetic CAN related to dizziness, presyncope, and syncope.
