Sleepless in middle age: A risky link to dementia

As individuals make their way through

middle age

, it’s often

sleep

that has to take a back seat to the demands of work and life. However, this could be serious, with a link to an increased risk of dementia. A study led by Dr. Séverine Sabia from Inserm and University College London explored the potential link between sleep patterns in midlife and the later development of dementia. Funded partly by the NIH’s National Institute on Aging (NIA), the research analyzed data from nearly 8,000 British adults, beginning at age 50. The findings indicated that individuals in their 50s and 60s who averaged six hours of sleep or fewer per night faced a higher risk of developing

dementia

in later years.
The sleep-dementia connection
Sleep is not a time of rest, but rather is a time when the brain works to repair itself. As per studies, while toxins are removed from most parts of the body and memories are consolidated, inadequate periods of sleep, such as in middle age, could impair these critical processes and result in later cognitive impairment.
Ageing and sleep patterns

Our sleep pattern changes naturally as we age. Many suffer from falling asleep but restorative sleep is necessary for maintaining brain health. Thus, middle-aged adults who fail to emphasize quality sleep may have a higher chance of dementia later in life.
Stress and lifestyle factors
It is in mid-adulthood when stress builds up with career, family, and social demands; resulting in pulling all-nighters. Lifestyle factors include screen time and poor diet supply. These are just some of the ways people end up without sufficient sleep. Chronic inflammation in the brain appears with chronic stress and poor lifestyle habits.

Signs you’re not sleeping enough
You should be aware of the symptoms of

poor sleep

. If you are constantly feeling tired, cannot concentrate, or tend to fluctuate in your mood, it is time to take another look at your sleep patterns. Getting enough sleep is a critical way to generally feel better and to think more clearly-protecting against dementia.
So, how do you improve the quality of your sleep? First of all, have a relaxing bedtime routine. For example, listen to soft music or read a book. Have a sleep-conducive environment: your bedroom must be dark, cool, and quiet. Reduce your caffeine consumption, especially in the afternoon. Avoid using screens right before bed.
A wake-up call
The connection between sleep deprivation and dementia is now a wake-up call for those in middle age. 7-9 hours of sleep and conscious lifestyle changes significantly improve

cognitive health

and overall quality of life. So go ahead and embrace the power of sleep-it just might become your best defence against cognitive decline.
