Benzodiazepines
Dependence associated with learning and memoryimpairment in elderly patients: clinical study
Results of a US study suggest that benzodiazepinedependence in patients ≥ 55 years of age can causelearning and memory impairment which persists afterbenzodiazepine detoxification.
The Auditory-Verbal Learning Test was used todetermine learning and memory abilities in 20 detoxifiedbenzodiazepine-dependent and 20 detoxified alcohol-dependent patients a mean of 6–10 days afterdetoxification, and in 22 controls; the mean age of allparticipants was 66 years.
Benzodiazepine-dependent patients showed moredifficulty with learning new material and short- and long-term memory recall of this material than patients in thealcohol-dependent or control groups.
All patients in the benzodiazepine group had beenusing the agents daily for several years; 10 patients for> 5 years. Six patients were using low to moderatelyhigh doses (0–39 mg/day of diazepam equivalent) and14 were using moderately high to high doses (≥ 40mg/day diazepam equivalent). 19 patients were usingbenzodiazepines with short to intermediate half-lives(most commonly alprazolam and lorazepam). Threepatients were using a longer-acting agent (diazepam)and 13 were using > 1 benzodiazepine.
