ABSTRACT
The epidemiology of diabetic and non-diabetic neuropathies in diabetic patients is important for agreement over its diagnostics criteria. The present study aimed to put the diagnostic criteria for both neuropathies in diabetic patients. The study comprised 60 diabetic patients with symptomatic neuropathy [40 males and 20 females] with age ranged from 21 to 82 year. They were subdivided into 2 subgroups, according to type of their diabetes, group 1 [45 patients with II DM] group 2 [15 patients with type I DM]. They were evaluated in order to know more about the cause of neuropathy in this population and the signs and symptoms that could suggest other cause than diabetes in this sitting. Diabetes accounted for [75%] of the neuropathies in the whole group of patients while twenty-five percent [25%] of patients have a neuropathy unrelated to diabetes. Chronic inflammatory demyelinating neuropathy that was diagnosed in 10%is the most common non-diabetic cause of neuropathy within population. A short interval between diagnosis of diabetes and the onset of the neuropathy, early motor deficit, markedly asymmetrical deficit and generalized areflexia, which are all uncommon in the diabetic neuropathy, in favor of a non-diabetic origin of the neuropathy and should lead to further investigations
