Poor sleep in older adults may accelerate frailty and cognitive decline

Poor sleep in older adults may speed up physical frailty and cognitive decline, according to new research. Experts now argue that sleep disorders should be treated with the same urgency as conditions like diabetes or high blood pressure. The findings highlight how addressing sleep problems could help preserve mobility and mental sharpness in later life.

A study published in BMC Geriatrics by Salvi and colleagues examined the link between sleep disturbances and worsening health in older adults. The research focused on those with sarcopenia—a condition marked by muscle loss—and found that poor sleep worsens both motor function and cognitive performance. The SOMNUS-DARE study further confirmed that disrupted sleep impairs muscle repair and brain adaptability, accelerating frailty.

The team recommended routine sleep assessments for older adults, particularly those showing early signs of muscle weakness or memory issues. For treatment, non-drug approaches were prioritised, including cognitive behavioural therapy for insomnia (CBT-I), controlled light exposure, and tailored exercise programmes. Medication, such as low-dose melatonin, was advised only if other methods failed, with oversight from a multidisciplinary team. Healthier, active elderly participants with milder sleep problems retained better mobility and thinking skills. This suggests that early intervention could delay disability. The study also stressed the need for sleep health to become a standard part of geriatric care, framing it as essential to precision ageing medicine.

The research points to sleep quality as a key factor in healthy ageing. By screening for sleep disorders and using targeted treatments, clinicians may slow physical and mental decline in older populations. Routine sleep assessments could soon join blood pressure checks as a core part of elderly care.
