Most research on diabetic neuropathy has focused on peripheral effects. But a pilot study showed that diabetic patients with established distal symmetrical polyneuropathy (DSP) had smaller cross-sectional cervical spinal cord areas than did diabetic patients without DSP.

In an attempt to confirm those preliminary findings. Dr. Dinesh Selvarajah and his colleagues conducted a study of 47 randomly selected men with type 1 diabetes. The goal was to determine if the CNS changes occur early enough for intervention to make a difference.
