The risk of suffering many of the most common age-related conditions is trending downwards over time, thanks to improvements in medical technology and public health, but the ever increasing size of the older segments of the population means that the incidence of those age-related conditions will nonetheless grow over time. Growth in the number of older people outweighs the reduced risk for any given individual, or at least this will be the case without much faster progress towards effective therapies than has taken place over the past few decades.
This is of great concern for those who focus more on socioeconomics than on health. The economic stress placed on centralized, government-run medical systems by this trend is perhaps one of the stronger motivations driving large-scale investment into research and development. Evidently still not strong enough, given that intervening in the aging process remains a tiny field in comparison to the rest of medicine, but we can hope that this will change given concrete results from the first rejuvenation therapies.
Across men and women and across most age groups, there has been a reduction in the prevalence of dementia
