Management Strategies for Better Sleep for People with Dementia

Here are a few things one can do for better sleep when suffering from dementia.


1. Managing One’s Medications

As aforementioned, medications can be the cause of sleep disorders in patients with dementia. So, if the sleep disorders are fairly new and are especially experienced after changes in the current medication, it is best to speak with a healthcare provider for more information.

2. A Cozy Bedroom

Comfort is crucial for everyone when it comes to sleep.

So, for someone suffering from insomnia, creating a healthy and cozy sleep environment should be a priority.

For instance, this can include a medium-firm breathable mattress like the Smart Ortho mattress by The Sleep Company, blackout curtains, soft lighting, and more. You must also make sure that the temperature of the room is just right. That said, the sleep environment must align with their preferences and needs.

3. Light or Cognitive Therapy

Patients with dementia can try therapies like light therapy. This can reset the circadian rhythm, which, in turn, can help manage sleep. There is also cognitive behavioral therapy, which helps cultivate good sleep habits. For this, it is important to speak with your healthcare provider.

4. Changes In One’s Lifestyle

Make sure that the person with dementia consumes a healthy balanced diet. They must also limit their consumption of caffeine and completely avoid alcohol. Even in the evening, their meals must be light, and they must keep themselves hydrated throughout the day.


The Final Word

Dementia is a condition with no cure currently. However, there are several treatments that can help manage symptoms to a great extent. That said, sleep is always a crucial factor when it comes to anyone's overall well-being. It's the same for people with dementia.

A good night's rest helps them maintain their brain health and it can also play a major role in managing the symptoms.

Therefore, start by creating a comfortable sleep environment that suits their needs. It can be bringing home a comfortable Smart Ortho mattress by The Sleep Company or choosing blackout curtains to block excess light. This first step can go a long way!
