Peripheral neuropathy

HP:0009830

What it means

Peripheral neuropathy is a general term for any disorder of the peripheral nervous system. The main clinical features used to classify peripheral neuropathy are distribution, type (mainly demyelinating versus mainly axonal), duration, and course.

Terms from this subhierarchy should be used to describe functional abnormalities seen in peripheral neuropathy. Morphological abnormalities should be coded separately.

The range is how often this sign appears among people diagnosed with each disease — it is not a probability of having any of them. Many of these signs also occur in common, non-rare conditions, and Orphanet separately records 3 diseases where this sign is specifically absent. A sign on this page is a conversation to have with a clinician, not a conclusion.
