Since older adults tend to need fewer hours of sleep – around 7 hours a night – than younger people, it might surprise you to learn that sleep deprivation can be quite common in older adults. Not only that, symptoms of sleep deprivation can also be confused for dementia in older adults.

Many people are aware that there is a connection between sleep and brain health. The changes in brain chemistry that occur when we don’t sleep leads to impairment of physical performance, decision making skills, and how well we manage our emotions. Poor quality sleep as well as insufficient hours of sleep makes us sluggish, causes muscle tension and physical fatigue, and can lead to changes in appetite and mood. The longer we go without good quality and sufficient hours of sleep, the more imbalanced brain chemistry and hormones become – and that is not good for the brain.

For older adults, who are less physically resilient to the stresses of poor sleep, the effects on their cognitive abilities can be significant. So much so, family members may wonder if their loved on is showing signs of dementia. 

How Can You Tell if an Elderly Adult is Sleep Deprived or Has Dementia?

Before you start calling assisted living centers about memory care services, you’ll want to carefully observe the sleep habits and behaviors of the older adult you are concerned about. First, you’ll want to understand the different symptoms of sleep deprivation versus dementia:

Symptoms of Sleep Deprivation

• Daytime drowsiness and fatigue not attributable to medication or a health condition
• Difficulty concentrating on everyday tasks that usually come easily
• Forgetfulness
• Changes in appetite – either eating too much or not enough
• Less resilient to stressful situations
• Irritability and mood swings
• Muscle tension and headaches
• Being more clumsy than usual, such as tripping or falling frequently

Early Symptoms of Dementia

• Everyday tasks that should come easily are causing frustration or other difficulty
• Changes in mood that represent a significant shift in personality
• Trouble communicating, following a conversation, and losing train of thought
• Forgetful and needing to repeat statements or questions repeatedly
• Difficulty concentrating
• Irritability, unusual anxiety, fear, or suspicion
• Neglecting their appearance and hygiene
• Confusion about time and place

As you observe your loved one for these symptoms, think about their sleep routine. Ask them (or observe):

• What is their sleep routine? (learn more about how to improve older adults sleep hygiene)
• Do they fall asleep easily?
• Do they wake throughout the night or not sleep at all?
• Upon waking, do they feel rested or fatigued?

Make notes based on your observation and talk with your loved one and their doctor about their sleep habits. If helping them get consistent quality sleep alleviates the symptoms you’ve observed, then you know they experienced sleep deprivation. With quality rest, you should see a return of healthy cognitive function.

If the symptoms you’ve observed don’t improve with better quality sleep, dementia may be developing. Now is the time to plan for your loved one’s quality of life as the symptoms of dementia will inevitably worsen.
