Prevention approaches ought to intention to lower danger issue ranges early (i.e., the sooner, the higher) and maintain them low all through life (i.e., the longer, the higher),” the researchers stated.
“Though addressing danger elements at an early stage of life is fascinating, there’s additionally profit from tackling danger all through life; it’s by no means too early or too late to cut back dementia danger.”

9. Hypertension and its trajectory — The researchers pressured within the earlier version of the Fee’s publication that hypertension can improve the danger of all-cause dementia, Alzheimer’s illness and vascular dementia.17
10. Weight problems — Analysis means that growing weight problems throughout midlife can improve the danger of all-cause dementia.18 These findings had been additionally supported in one other examine, including that the danger is bigger in individuals older than 65 years in comparison with different age teams.19
11. Extreme alcohol consumption — Ingesting alcohol with a complete ethanol content material increased than 168 grams per week throughout midlife is related to an elevated danger of dementia.20 These findings had been additionally echoed in a meta-analysis consisting of 131,415 individuals all through Europe.21
In one other examine,22 this time involving South Koreans, researchers discovered that heavy consuming elevated the danger of dementia. Conversely, the examine famous that even simply decreasing consumption to a reasonable quantity can already decrease the danger.

“The potential for prevention is excessive and, general, practically half of dementias might theoretically be prevented by eliminating these 14 danger elements. These findings present hope. Though change is troublesome and a few associations is perhaps solely partly causal, our new proof synthesis reveals how people can cut back their dementia danger …”
