Do you have any research papers to show that mental activity delays onset of dementia illnesses? So far what I&#x27;ve seen has been poor quality studies or early investigations.  So, it might help, but we don&#x27;t know yet.<p>The part I was mostly querying was about money being protective.  It probably isn&#x27;t. rich people probably get dementia at the same rate as poor people.<p><a href="https:&#x2F;&#x2F;www.nia.nih.gov&#x2F;alzheimers&#x2F;publication&#x2F;preventing-alzheimers-disease&#x2F;search-alzheimers-prevention-strategies" rel="nofollow">https:&#x2F;&#x2F;www.nia.nih.gov&#x2F;alzheimers&#x2F;publication&#x2F;preventing-al...</a><p>&gt; Unlike age and genetics, certain health and lifestyle factors associated with Alzheimer’s disease risk may be controlled. Scientists are exploring prevention strategies to determine whether or not things like exercise, diet, and “brain games” can help delay or prevent Alzheimer’s disease and age-related cognitive decline. They are also investigating how certain medical conditions, such as high cholesterol, high blood pressure, and diabetes, influence risk for cognitive impairment.<p>&gt; So far, studies have not demonstrated that, over the long term, health or lifestyle factors can prevent or slow Alzheimer’s disease or age-related cognitive decline. Similarly, clinical trial results do not support the use of any particular medication or dietary supplement to prevent these conditions.
