And many individuals assume there’s nothing they will do to keep away from that destiny—that dementia is “certainly one of these items that simply occurs,” says Gill Livingston, a professor within the division of mind sciences at College Faculty London.
However a brand new report printed in The Lancet says in any other case. Practically half of dementia circumstances might, actually, be prevented or delayed if individuals adopted sure habits, in line with the report, which was written by a gaggle of virtually 30 specialists convened by the Lancet and primarily based on an evaluation of tons of of research.
Some danger elements for dementia may be finest addressed by way of coverage options—for instance, by passing local weather insurance policies that cut back the general public’s publicity to air air pollution, a danger issue for cognitive decline. However there’s additionally a lot that people can do. Even individuals with genetic danger elements for dementia could possibly lengthen their cognitively wholesome lifespans in the event that they take sure actions, says Livingston, lead creator of the report.
Right here’s the place to begin, in line with the most recent analysis.

And for those who can, get transferring exterior. A 2022 examine suggests spending time in inexperienced area might preserve the thoughts wholesome.
