The link between lack of sleep and dementia

The link between lack of sleep and dementia

Have you heard of Dementigenes? They sound like the type of bad guys that Dr Who would fight against,
well, if Dr Who slept only 5 or 6 hours every night, he might be fighting them, if he wanted to avoid dementia!

Dementigenes are things that cause dementia, they damage our brain.

An inflammatory diet is the number one cause of dementigenes.
Processed food, sugar, starch, lack of protective nutrients and allergens like gluten and dairy can be.

Lack of exercise is also a dementigene.
Exercise is one of the best ways to activate BDNF, which is the miracle growth for your brain.

Other dementigenes are stress, environmental toxins, such as heavy metals, mercury and lead.
and lack of relationships, lack of social connections, social interactions, affects your brain and makes it decline and are dementigenes.

But a major dementigene, is lack of sleep.

Every night your brain has to clean up the garbage from the glymphatic system.
It’s like the lymph system of your brain.
When you don’t have a good quality sleep, you can’t get rid of all that metabolic waste.
It’s one of the most metabolically active organs in your body.
And there is a lot of waste that’s produced as a result of that metabolic activity.
Your body cleans it up by the glymphatic system, which is active at night.

Sleep is absolutely critical for this process.
Good quality and quantity of sleep allow the glymphatic system to do it’s job properly,
protecting against dementigenes, and also against alzheimers.

This is another reason it’s vital to make sleep a priority, and to ensure you get at least 7 hours sleep a night, as often as possible.


I help my clients to think about creating health.
To look at the body as a whole system,
to look at Sleep, Breathing, Nutrition, Movement & Mindset,
to optimize the essential functions of our body to create health,

By helping the people I work with improve their sleep quality and quantity, they get more deep sleep and REM sleep.
They have better functional breathing so they don’t get out of breath so quickly, and can play with their grandkids.
We explore foods that aid their autoimmune system rather than creates inflammation and fights against it.
We discuss the most appropriate form of regular movement for their lives so they’re not so prone to breaking bones if they fall down
and above all to have the mindset of knowing they can take responsibility for their own health, and be proactive about it,
rather than what so many people do, which is to be reactive, and wait until the pain, or the tumour shows or receive the diagnosis

When you create health, often disease goes away as a side effect.
