The need to prevent dementia highlighted in latest research
The latest large scale research into dementia, Parkinson’s disease and stroke has confirmed that one in two women and one in three men will develop at least one of these diseases during their lifetime. The research offers insight into the long term health of people in their 40s. But in addition to highlighting the stark statistical probability of succumbing to neurodegeneration, the study suggests that delaying the onset of the these illness for 1 – 3 years may reduce the risk of avoiding them altogether by 20% to 50%.
It is widely recognised that a number of lifestyle factors can increase the probability of avoiding dementia. Stopping smoking, adopting a healthy diet and taking regular exercise have long been associated with improved physical and mental health. Recent scientific studies have also given the strongest indications yet that some forms of meditation might be directly reducing the rate at which a brain ages, enabling us to maintain full brain (cognitive) function for longer. We know that cognitive decline begins in our late 20s and early 30s. It will normally be visible by the age of 45. If our cognitive ability continues to shrink through middle age it can lead to a diagnosis of mild cognitive impairment and eventually even dementia.
“one study revealed that at the age of 50, regular meditators had brains several years younger than non-meditators”
Research has shown that meditation can lead to a slowing of brain ageing and an improvement to certain brain functions such as memory and attention. Although the understanding of how meditation is able to help create new brain structure is still at a preliminary stage. There is compelling evidence that some forms of meditation are related to maintaining, and in some respects improving our brain health. Although brain training (including meditation) can reduces the risk of developing dementia it is just one of a number of things we can do to live longer healthier lives.
