Objective: Benzodiazepines and Z-drugs are two of the most prescribed agents worldwide. However, because of their cognitive side effects, the question of their influence on the risk of dementia has been raised. The authors examined the association of benzodiazepines, Z-drugs, and other anxiolytics with incident dementia in patients with affective disorders.
Methods: The authors conducted a cohort and nested case-control study of 235,465 patients over age 20 who were identified in the Danish National Patient Registry as having had a first-time hospital contact for an affective disorder between 1996 and 2015. From the Danish National Prescription Registry, information was obtained on all prescriptions for benzodiazepines, Z-drugs, and other anxiolytics, and patients were followed for incident dementia (defined by hospital discharge diagnosis or acetylcholinesterase inhibitor use). Cox proportional hazards and conditional logistic regression models were used to calculate hazard ratios and odds ratios with adjustment for sociodemographic and clinical variables.
