Long-Term Peripheral Nerve Function in People with Well-Controlled Type 2 Diabetes
The authors conducted a prospective observational study comparing the effect of early diagnosed, well-controlled type 2 diabetes on peripheral nerve function. Overall, they found similar rates of decline in nerve function in people with well-controlled diabetes compared to age- and sex-matched individuals with normal glucose tolerance. Given the similar decline in nerve function, the authors concluded that the course of diabetic sensorimotor neuropathy is influenced primarily by nerve function at the time of diagnosis and age-related physiological decline.
