Description of peripheral nervous system involvement in wild-type transthyretin amyloidosis: A clinical and electrophysiological study

In our cohort, a large majority of ATTRwt patients showed peripheral nerve involvement, generally expressed as the combination of different neurological syndromes (entrapment syndromes, large and/or small fiber polyneuropathy, radicular impairment). Polyneuropathy in ATTRwt seemed stable over our follow-up period. Clinical and EDX screening should be conducted in ATTRwt patients with symptoms suggestive of neurological involvement in order not to oversee these frequent complications which could affect therapeutic decision making.
