It is estimated that there are around 50 million people worldwide with dementia – the general term for progressive cognitive decline – which affects all aspects of thinking and emotions. An estimated 460 live in Australia alone. 000 people with some form of dementia and approximately 1 million people are involved in some way in their care, either as relatives or from the health sector. There are no definitive therapies that could affect this process, although there are currently some promising treatments in clinical trials that may become available over the next several years.
The most common cause of dementia is Alzheimer’s disease, but there are many other factors that contribute to cognitive decline. For example, chronic abuse of legal and illegal substances can lead to dementia – like excessive alcohol, marijuana, and other illegal drugs like cocaine and ecstasy. Chronic traumatic encephalopathy (a broad term for brain disease) due to a severe head injury or repeated blows to the head from a variety of sports can also contribute to dementia. Certain nutritional deficiencies – particularly in the B group vitamins – can also have an impact, and there are a variety of less common genetic disorders that can lead to dementia. The very common vascular dementia is the second most common form of dementia after Alzheimer’s disease.
A study was published in the Journal of American Medical Association (JAMA) Neurology last year linking sleep apnea to cognitive decline. This finding is important because most men and the majority of women after menopause have some degree of sleep apnea. Sleep apnea is the condition in which breathing becomes impaired while you sleep, causing recurring bursts of oxygen starvation in the body. As you can imagine, a nighttime lack of oxygen in the brain can contribute to progressive cognitive decline over several years.
The study looked at 127 men and women living in France with an average age of 69 years. 1 year. They had assessed their cognitive function and sleep quality, and at the start of the study none of the participants had any signs of memory loss. They were given portable home devices to record their sleep quality and breathing while they slept, and had various tests for memory and cognitive function. They also underwent MRIs and even the more sophisticated FDG PET scans to measure sugar metabolism in the brain.
In the significant proportion of people who suffered from sleep apnea in the study, a clear accumulation of amyloid proteins was observed in the brain of people with different degrees of dementia. This was not seen in people who did not have significant sleep apnea. The brain scans of people with sleep apnea also showed inflammation in key areas of the brain for thought.
Sleep apnea is directly linked to all forms of cardiovascular disease, including high blood pressure, heart attack, and stroke. There is also a link to diabetes and obesity, as well as a wide variety of cancers. Well, it seems we can add dementia to the list.
As with any modern disease, it is best to take steps to prevent it from occurring in the first place. The sooner you researched and treated the conditions, the better. If you don’t wake up refreshed and feel tired throughout the day, it is certainly possible that you have sleep apnea. Therefore, this needs to be investigated and dealt with as soon as possible. Who wants the alternative? Fortunately, sleep apnea is extremely treatable. As we get older it is vital that we maintain our mental sharpness and I believe that we should use every possible trick to do this.
