Nevertheless, there was disagreements about which type of PD might benefit more from MAO-B inhibitors, and an extremely significant disparity (p < 0.0001) on familiarity with the use of disease-modifying/neuroprotective therapy (χ2(N = 711) = 42.9005, p < 0.0001), Rivastigmine for PDD patients (χ2(N = 711) = 20.2759, p < 0.0001), and antipsychotics for psychiatric symptoms managements (χ2(N = 711) = 21.8987, p < 0.0001). Here, MAOB is linked to Parkinson disease.
