Individuals \u226550\u2009years old with dementia or AD were identified using AD and dementia-related diagnostic codes, medications, and keywords searched using natural language processing (NLP) and Artificial Intelligence (AI) algorithms from EMR chart notes. Diagnostic and screening tools included scales, neuroimaging, and laboratory tests. Medications examined were cholinesterase inhibitors, memantine, antidepressants, and antipsychotics.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Results:<\/jats:title>\n                    <jats:p>The study cohort included 417 individuals with all-cause dementia (mean [standard deviation: SD] age: 78.86 [0.19] years), and 71 individuals with AD (mean [SD] age: 76.13 [1.07]). The most-used scale was the Montreal Cognitive Assessment (MoCA; dementia: 53.2%, AD: 84.5%). The mean [SD] frequency of MoCA administration doubled in the year following AD index date compared to the year prior (0.29 [0.82] to 0.67 [1.19] times per patient-year). Severity scores, often unspecified, suggested various stages of cognitive impairment. Among the medications examined, cholinesterase inhibitors were prescribed in 27.8% (n\u2009=\u2009116) and 57.8% (n\u2009=\u200941) of people with dementia and AD, respectively. Antidepressants were the most frequently prescribed medication examined (dementia: 49.6%; AD: 71.8%).<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Conclusion:<\/jats:title>\n                    <jats:p>PCPs play an important role in the early detection and management of dementia\/AD.
