Neuropathic symptoms can be assessed by the polyneuropathy disability (PND) score; neuropathy symptom score; neurologic disability score (NDS); neuropathy impairment score (total NIS), and neuropathy impairment score–lower limb (NIS-LL), scales that quantify neurologic function in patients with diabetic polyneuropathy but are also valuable for patients with TTR-FAP; autonomic reflex screen; composite autonomic severity score; mBMI; electromyography with SSR; and other original scores or local variants. Here, FAP is linked to polyneuropathy.
