It was previously thought that doing crosswords and riddles helped to prevent Alzheimer's for the entire population; however, a recent study has revealed that this is only effective for those who are already at risk for the disease via a faulty gene. In these people, working their minds helps to prevent the build up of sticky amyloid plaque that eventually presents as Alzheimer's.
But: that doesn't mean the rest of us should be putting our puzzle books down.
Doing puzzles and riddles can help improve our memory and processing speeds, which in turn allows us to stay sharp and mentally healthy (healthier) as we age.
Developing logic and problem solving skills by working our way through hypothetical scenarios and ideas gives rise to a sense of confidence and accomplishment, and greater emotional resilience. If we're used to looking at problems as things which can ultimately be solved, and believe we have the skills and intellect to manage difficult riddles and issues, then we're going to be much better at solving our own real life problems.
If you'd like to find out whether you have a higher risk of developing Alzheimer's as a result of your genetic code, tests are available - and at the same time, we can provide information about any other genetic factors which may be impacting your health.
