It is a rare disease with a higher prevalence in Asian countries compared with other countries. The most common symptoms of MMD vary from stroke to epileptic seizure and headaches.

Impact of amyloid-PET in daily clinical management of patients with cognitive impairment fulfilling appropriate use criteria.

To evaluate the use of amyloid-positron emission tomography (PET) in routine clinical practice, in a selected population with cognitive impairment that meets appropriate use criteria (AUC).A multicenter, observational, prospective case-series study of 211patients from 2 level-3 hospitals who fulfilled clinical AUC for amyloid-PET scan in a naturalistic setting. Certainty degree was evaluated using a 5-point Likert scale: 0 (very low probability); 1 (low probability); 2 (intermediate probability); 3 (high probability); and 4 (practically sure), before and after amyloid PET.
