There is no method that has been proven to prevent the occurrence of dementia later in life, according to an analysis of numerous studies.
A team of researchers from the Minnesota Evidence-based Practice Center wanted to see whether vitamins and supplements, brain training, prescription medications, or physical activity can help in preventing dementia.
The researchers wanted to analyze possible interventions for dementia because the number of dementia patients is expected to rise sharply as the population ages.
The team, however, found that none of the interventions was successful and nothing seemed to prevent the condition after analyzing four systematic reviews and their findings. The researchers published their paper in the journal Annals of Internal Medicine.
