Dementia patients caregivers lose up to 2.5 to 3.5 hours of sleep per week due to difficulty falling and staying asleep.
Dementia patients caregivers lose upto2.5 to 3.5 hours of sleep per week due to difficulty falling and staying asleep. This habit is negative for themselves, and potentially for those who receive their care, Baylor University researchers say. But the good news is that simple, low-cost interventions can improve caregivers’ sleep and functioning.
‘Caregivers are truly inspiring and hardest-working people in the world, but sleep loss eventually reaches a level that decreases one's vigilance and multi-tasking.’

The researchers’ analysis of 35 studies with data from 3,268 caregivers -- "Sleep Duration and Sleep Quality in Caregivers of Patients with Dementia" -- is published in JAMA Network Open, a publication of the American Medical Association.Read More..
Informal caregiving for a person with dementia is akin to adding a part-time but unpaid job to one’s life, with family members averaging 21.9 hours of caregiving, according to The Alzheimer’s Association estimates.
"Losing 3.5 hours of sleep per week does not seem much, but caregivers often experience accumulation of sleep loss over the years," said lead author Chenlu Gao, a doctoral candidate of psychology and neuroscience in Baylor’s College of Arts & Sciences. "Losing 3.5 hours of sleep weekly on top of all the stress, grief, and sadness can have a really strong impact on caregivers’ cognition and mental and physical health. But improving caregivers’ sleep quality through low-cost behavioral interventions can significantly improve their functions and quality of life."
Chronic stress is associated with short sleep and poor-quality sleep. Nighttime awakenings by a patient with dementia also can contribute to disturbed sleep in caregivers, researchers said. "With that extra bit of sleep loss every night, maybe a caregiver now forgets some medication doses or reacts more emotionally than he or she otherwise would," said co-author Michael Scullin, Ph.D., director of Baylor’s Sleep Neuroscience and Cognition Laboratory and assistant professor of psychology and neuroscience at Baylor.
"Caregivers are some of the most inspiring and hardest-working people in the world, but sleep loss eventually accumulates to a level that diminishes one’s vigilance and multi-tasking." Notably, better sleep was observed in caregivers after such simple behaviors as getting more morning sunlight, establishing a regular and relaxing bedtime routine, and taking part in moderate physical exercise.

For the analysis, researchers searched articles in peer-reviewed journals and books addressing caregivers, sleep, dementia, and Alzheimer’s disease, published through June 2018. Those studies measured sleep quality and quantity by monitoring brain electrical activity, body movements, and self-reporting by caregivers.

Baylor researchers’ analysis found that caregivers slept less and perceived their sleep quality to be worsening. That means that they were not simply adapting - or not "needing" - sleep. Importantly, caregivers could improve their sleep through behavioral changes, as expected by the "coping" view of caregiving.
"Given the long-term, potentially cumulative health consequences of poor-quality sleep, as well as the rising need for dementia caregivers worldwide, clinicians should consider sleep interventions not only for the patient but also for the spouse, child or friend who will be providing care," Gao said.
