We thank Dr. James for his comments1 on our paper, Clinical Practice Guideline for Pharmacologic Treatment of Chronic Insomnia in Adults.2 Although there is uncertainty regarding increased risk of dementia associated with use of benzodiazepines (BZD) and BZD receptor agonists (see Imfeld et al.),3 Dr. James is correct in asserting that clinicians must consider this, as well as numerous other potential adverse consequences of hypnotic medication, particularly in the elderly.

The adverse effects described in our systematic review were drawn only from the efficacy studies that met overall inclusion criteria. We note in our publication that “the data (from studies included in this analysis) are scant and inconsistent, suggesting that caution should be applied in the assessment of relative risks associated with use of hypnotic medications.” We also note that there are many additional observational studies that address these and other potential adverse effects; “Other reported adverse effects include—but are not limited to—dependency/withdrawal, cognitive impairment, falls/fractures, parasomnias, and driving impairment and motor vehicle accidents. Epidemiological studies have also suggested a possible link between hypnotic use and infection, depression and overall mortality risk. These complications are observed most frequently in older populations, who are among the most frequent users of these drugs.” Per Dr. James' comment, dementia could be listed among the conditions related to BZD hypnotic use in epidemiological studies. Although these observational studies are beyond the scope of our investigation, they are by all means important considerations for clinicians who are prescribing these drugs.
