   Proposal Description:
   Utilizing neuropathological verification and pre-mortem interview and clinical data from the National Alzheimer Coordination Center, the objective of this secondary analysis will be to examine cross-sectional and longitudinal variations between two cohorts of patients, matched on level of cognitive impairment, age, and gender: a) those who receive an in-vivo/pre-mortem diagnosis of Alzheimers disease and receive confirmed neuropathological diagnosis of Alzheimers disease (i.e., the matched group) and b) those who receive an in-vivo/pre-mortem diagnosis of Alzheimers disease but do not receive neuropathological confirmation of Alzheimers disease  (i.e., the mis-matched group).  We aim to examine statistical variations in patient sociodemographics, functional dependency, neuropsychiatric symptoms, depressive symptoms, medication use (e.g., anticholinesterate inhibitors, NMDA antagonists like Memantine and typical antipsychotics), and residential care use to determine the clinical ramifications of a mis-matched AD diagnosis. If samples sizes permit, we will also examine statistical variations among the aforementioned two groups with two additional cohorts: c) those who do not receive an in-vivo/pre-mortem diagnosis of Alzheimers disease but do receive confirmed neuropathological diagnosis of Alzheimers disease (i.e., mis-matched 2 group, and d) those who do not receive an in-vivo/pre-mortem diagnosis of Alzheimers disease and do not receive confirmed neuropathological diagnosis of Alzheimers disease (i.e., controls).
