Incidence of dementia : secular trends and associated factors

Abstract : Consequences of dementia are impacting not only patients, but also their family and even society; it has thus been highlighted as an important public health priority. Understanding temporal trends of this disease thus became a major research topic, critical for the future. This thesis aimed at investigating secular trends of dementia incidence as well as some of its components and consequences, trying tounderstand their determinants. In the first part of this work, we have brought further evidence toward a decreasing trend of dementia incidence, only found for women between the 90’s and the 2000’s in our study. Then, we have reported a global improvement of cognitive performance for younger elderly generations, potentially due to improvement early in life rather than to a slower decline across aging. Finally, we have evidenced a decrease in mortality without dementia and for demented women, as well as an increase of healthy life expectancy and survival with dementia. These results are in line with an improvement of health of older people during the last two decades, which is promising for the future.Further research to better understand these secular trends are yet needed ; it will help precise prevention strategies needed to reduce or delay dementia.
