Sleep and Dementia: a Link That We Never Thought About

Sleep and Dementia: a Link That We Never Thought About

Even if we’re healthy, we all have periods of disturbed sleep. In most cases, we look at our sleep habits to determine what’s causing our insomnia and then work to find a solution. Sometimes, we even consult a doctor. However, sleeplessness might be an indicator of dementia, based on research. Also, Alzheimer’s disease is the most prevalent kind of dementia, yet it may take years before you notice any symptoms.

Here’s what you need to know.

Does Sleeping Affect Your Risk of Developing Dementia?

Experts are unsure, to put it kindly, about the order of events. Dementia and poor sleep quality undoubtedly interact in negative ways. Sleep is crucial at any time. It’s crucial to practice this every day since it aids in learning and memory retention. And studies suggest that if your sleep is disrupted, you’re more likely to struggle with those tasks. The question is, “How?”

Insufficient sleep alters the structure and function of the brain. There is a connection between Alzheimer’s disease and some of these fields. Unfortunately, those under the age of 40 who suffer from primary insomnia are more likely to develop Alzheimer’s disease. That’s startling, to put it mildly.

Memory Loss with Nighttime Sleep

The relationship between sleep duration and mental deterioration appears to be connected. Let’s take a closer look at some of the possible sleeping habits you or someone you care for may have:

1. Sleeping fewer than 7 hours a night

Sleep deprivation has been associated with an increase in beta-amyloid and tau, two proteins implicated in Alzheimer’s disease. What’s more, slow-wave sleep, which aids in learning and memory, is disrupted by insomnia.

2. Sleeping more than 8 hours

Let’s say this one is not a really big deal. The link between lengthy sleep duration and an increased risk of dementia remains unclear. But it should make you wonder if there could be anything more serious going on, like depression or sleep apnea.

Regardless, if you ever feel confused about your own health, it’s important to contact a doctor.
