Benzodiazepines: A Sleep Saboteur?

Benzodiazepines, widely prescribed in Quebec for anxiety and insomnia, may actually be sabotaging sleep quality among older adults in the long run. A recent groundbreaking study from Concordia University indicates that these medications can lead to worse sleep and an increased risk of falls in seniors.

The Danger Lurking in Your Medicine Cabinet

Commonly known benzodiazepines, such as Valium, Xanax, and Ativan, disrupt brain rhythms essential for sleep—crucial for memory and cognitive function in individuals aged 55 and up. The study involved 101 older adults, categorized into three groups: good sleepers, those suffering from insomnia, and chronic benzodiazepine users.

Experts Sound the Alarm

Lead researcher Loïc Barbaux, a PhD candidate at Concordia, cautions that while there aren't major concerns for younger adults using these drugs short-term, seniors over 65 should steer clear. The American Geriatrics Society warns that the risks far outweigh any benefits, making these medications a risky gamble.

Addiction and Withdrawal: A Dangerous Cycle

Not only do these drugs fail to enhance sleep, but they also have addictive properties. Discontinuing benzodiazepines abruptly can trigger withdrawal symptoms like tremors and heightened fall risk—a serious concern for the elderly, where even minor falls can lead to devastating injuries like hip fractures.

A Decrease in Dangerous Prescriptions?

On a positive note, healthcare providers are becoming more cautious in prescribing benzodiazepines. Data shows that the proportion of seniors in Quebec using inappropriate medications dropped significantly from 49% in 2012 to 45% in 2022, largely due to a decrease in benzodiazepine prescriptions.

The Reality of Sleep vs. Perception

Many who take benzodiazepines report feeling their sleep quality improves. However, Barbaux emphasizes the importance of distinguishing subjective feelings from objective sleep quality. Using overnight polysomnography, the researchers found that while REM sleep remained unchanged, deep sleep—a key player in memory consolidation—dropped significantly.

Seeking Safer Solutions

Fortunately, alternatives exist, such as cognitive behavioral therapy, which has proven effective in restoring sleep quality when combined with medication withdrawal. Barbaux insists that further research is crucial to find targeted interventions that can effectively address the complex sleep issues faced by seniors.

The Challenge Ahead

The journey to better sleep for the elderly population is fraught with challenges, but finding effective solutions that improve sleep both subjectively and objectively is of utmost importance. It’s time for a shift in how we approach sleep difficulties in seniors.
