Study population: This study will involve a new user, parallel group, cohort study design comparing TNF inhibitors to abatacept. The patients will be required to have continuous enrollment during the baseline period of 355 days before initiation of TNF inhibitors or abatacept (cohort entry date). Follow-up for the outcome (incident dementia), begins the day after drug initiation for analyses 1, 3, and 4 and 180 days after drug initiation for analysis 2.

Brief summary: This study aims to evaluate the comparative risk of dementia/Alzheimer's disease onset between patients treated with medications that target specific metabolic pathways and patients treated with alternative medications for the same indication.

Detailed description: This is a non-randomized, non-interventional study that is part of the DREAM Study of Brigham and Women's Hospital. DREAM is led by Dr. Madhav Thambisetty, MD, PhD, Chief of the Clinical and Translational Neuroscience Section, Laboratory of Behavioral Neuroscience, National Institute on Aging (NIA) intramural research program. This study aims to evaluate the comparative risk of dementia/Alzheimer's disease onset between patients treated with medications that target specific metabolic pathways and patients treated with alternative medications for the same indication using healthcare claims data.
