|(i) N: neurological domain symptoms, V: visceral domain symptoms, and P: psychiatric domain symptoms.|
(ii) Combined manifestations (scores): V + N = 40 points, V + P = 40 points, and P + N = 20 points.
(iii) Family history (scores): 1st degree = 40 points and 2nd degree = 10 points.
(iv) Total Risk Predication Score for NP-C: <40 = low probability of NP-C and alternative causes should be considered. A score of 40–69 = moderate suspicion of having NP-C; further follow-up observation is required and contact NP-C referral center for further discussion. A score of ≥70 = high suspicion of having NP-C and should be immediately referred to an NP-C center for testing for NP-C.
