Insomnia is a very common medical complaint, and increases with age. Patients with insomnia often report increased daytime fatigue, confusion, anxiety, and depression. While insomnia can have a significant negative impact on quality of life, a recent study highlights the need for careful consideration in the use of sleeping medication to manage this condition, especially among older adults.
It is widely recognized that the use of traditional “benzodiazepine” type sleeping medication (e.g. nitrazepam), increase the risk of fractures and falls in older adults.

In fact, these drugs have been marketed as safer than benzodiazepine medication, and are often perceived as such by clinicians and patients alike. Continue reading →

Sleep disorders including insomnia, obstructive sleep apnoea and restless legs all increase in prevalence with age but the effects of disturbed sleep in the oldest age groups are still poorly understood. Sleep becomes increasingly fragmented, although total sleep time does not change significantly and there is weakening of the circadian rhythm which is likely to be both biological and environmental.
