               APPENDIX B. Clinical Assessment Scales Commonly Used in AD
               Therapeutic Trials



               Domain / Scale                     Description


               Cognition                          Memory, orientation, language, praxis, etc.


               Mini-Mental State Exam (MMSE)      30-pt. scale (higher scores better)
                                                  Clinician administered patient evaluation
                                                  Mostly used for eligibility screening and dementia staging


               Alzheimer’s Disease Assessment     70-pt. scale (higher scores worse)
               Scale-cognitive subscale (ADAS-    Clinician administered patient evaluation
               cog)                               Standard cognitive outcome measure in mild-moderate AD


               Severe Impairment Battery (SIB)    100-pt. scale (higher scores better)
                                                  Clinician administered patient evaluation
                                                  Cognitive outcome measure used in moderate-severe AD


               Global Change                      Summary outcome assessment from baseline to endpoint


               Clinical Global Impression of      7-pt. scale (1 = very much improved, 4 = no change, 7 =
               Change (CGI-C)                     very much worse)
                                                  Clinician rated, based on patient +/- informant interview


               Clinician’s Interview-Based        7-pt. scale (1 = very much improved, 4 = no change, 7 =
               Impression of Change Plus          very much worse)
               Caregiver Input (CIBIC-Plus)       Clinician rated (with caregiver input), based on semi-
                                                  structured interview covering cognition, behavior, function


               Global Deterioration Scale (GDS)    7-pt. scale (1 = no decline, 7 = very severe decline)
                                                  Clinician rated based on cognitive change only
