Diagnosis & Tests
Physical examination, including nervous system (neurological) and sensory tests, may diagnose neuropathies. A common early finding is the absence of ankle reflexes.
Health care providers often test for loss of sensation in the feet with a brush-like instrument called a monofilament.
Electrodiagnostic testing may be done.
