Prevalence of polyneuropathy in the general middle-aged and elderly population

Abstract

Prevalence of polyneuropathy in the general middle-aged and elderly population is at least 4%, and increases with age. Almost half of the cases were newly diagnosed, indicating that the presence of polyneuropathy is underreported or underdiagnosed. Currently, almost half of the polyneuropathies are idiopathic. Future prospective cohort studies should focus on identifying new determinants of polyneuropathy.
