Benzodiazepines are associated with increased risk of Alzheimer’s disease

The use of benzodiazepines and related drugs (Z drugs) is associated with a modestly increased risk of Alzheimer’s disease, according to a recent study from the University of Eastern Finland. The risk increase was similar with both benzodiazepines and Z drugs regardless of their half-life. The results were published inĀ Acta Psychiatrica Scandinavica.

Even though the increased risk for Alzheimer’s disease was small in this study, the threshold for prescribing benzodiazepines and related drugs should be high enough due to their several adverse effects and events, such as falls. These medications are commonly used for sleep problems, but their effectiveness for this indication diminishes over weeks or months. However, the risk of adverse events remains in longer-term use.
