Study strengthens evidence that cognitive activity can reduce dementia risk

Study strengthens evidence that cognitive activity can reduce dementia risk:

Dementia Big
Are there any ways of preventing or delaying the development of Alzheimer’s disease or other forms of age-associated dementia? While several previously published studies have suggested a protective effect for cognitive activities such as reading, playing games or attending cultural events, questions have been raised about whether these studies reveal a real cause-and-effect relationship or if the associations could result from unmeasured factors. To address this question, a Boston-based research team conducted a formal bias analysis and concluded that, while potentially confounding factors might have affected previous studies’ results, it is doubtful that such factors totally account for observed associations between cognitive activities and a reduced risk of dementia.
