Diabetic neuropathy is the most common neuropathy in industrialized countries, and it is associated with a wide range of clinical manifestations. The vast majority of patients with clinical diabetic neuropathy have a distal symmetrical form of the disorder that progresses following a fiber-lengthdependent pattern, with sensory and autonomic manifestations predominating. This pattern of neuropat...

Nerve ischemia, both acute and chronic, may contribute to diabetic neuropathies, but the pathogenesis remains obscure. The vulnerability of diabetic nerve to ischemia was assessed by ligating arteries of supply of rat sciatic nerve after 20 wk of streptozocin-induced diabetes. In the first 24 h after the arterial ligations, severe and more rapidly occurring clinicopathological abnormalities wer...

SECTION 1: INTRODUCTION — The neuropathies are among the most common of the long-term complications of diabetes, affecting up to 50% of patients (1–4). Their clinical features vary immensely, and patients may present to a wide spectrum of specialties, from dermatology to podiatry, for example, or from urology to cardiology. Neuropathies are characterized by a progressive loss of nerve fibers, w...

INTRODUCTION Changes in human behaviour and lifestyle over the last century have resulted in a dramatic increase in the incidence of diabetes worldwide. Neuropathy is a common and costly complication of both type 1 and type 2 diabetes. The prevalence of neuropathy is estimated to be about 8% in newly diagnosed patients and greater than 50% in patients with long-standing disease. There are two m...

Electrodiagnostic (EDX) patterns of neuropathic dysfunction have been based on axonal/demyelinating criteria requiring prior assumptions. This has not produced classifications of desired sensitivity or specificity. Furthermore, standard nerve conduction studies have limited reproducibility. New methodologies in EDX seem important. Recurrent Quantification Analysis (RQA) is a nonlinear method fo...

Neuropathies are among the most common of all the long-term complications of diabetes, affecting up to 50% of patients.1–5 There are many subgroups of neuropathies; readers are referred to recent reviews for discussion of the autonomic neuropathies6 and the mononeuropathies.7 This article will focus on the most common of all the peripheral neuropathies: the somatic neuropathies affecting the lo...
