Women far more likely to suffer neurodegenerative conditions than men
Research from the Netherlands indicates that women at age 45 have a 48% lifetime risk of developing Parkinson’s disease, dementia or having a stroke. The risk for men at the same age is 12% lower at 36%. The headline findings of this large scale study are
“from age 45, 1 in 2 women and 1 in 3 men are likely to develop dementia, Parkinson’s or have a stroke during their lives.”
This research draws attention to a number of important findings. It confirms that women appear to be more likely to develop dementia in later life than men, this is in line with existing predictions. Specifically that at the age of 45 women had a 26% likelihood of developing dementia, for men the probability was around 14%. That from middle age women have a 1 in 4 chance of developing dementia but for men this is about a 1 in 7 chance.
This study (Lifetime risk of common neurological diseases in the elderly population) was conducted by researchers at the University Medical Center of Rotterdam, it is regarded as so important that it has been widely reported in the media. The scale of the investigation adds great significance to the findings, the data of 12,102 individuals over a 26 years period provided that basis for the analysis. Recommendations from the report include the emphasis on preventative strategies at the level of population. This clearly supports a move to approaches able to delay the initial onset of diseases such as dementia. The statistical benefit for delaying the early stages of these conditions by 1 to 3 years, has been calculated at as reduction in lifetime risk of developing the disease of between 20% to 50%.
Put simply, delay the conditions leading to dementia, Parkinson’s and stroke for 1 to 3 years and your chances of ever developing the diseases may be reduced by up to half. This illustrates the basic principle that even small changes to lifestyle can lead to fundamental improvements in your lifelong health trajectory. Prevention of dementia should begin in your 40s not 60s. There appears to be little doubt that stopping or slowing neurodegenerative processes offers significant benefits to individuals and society as a whole.
