Positive thinking & stroke

The Power of Positive Thinking

Previous research has shown that low pessimism and temporary positive feelings are related to a reduced risk of stroke; however, this study is the first to examine the relationship between optimism and stroke among older adults in a prospective study with a large and nationally representative sample.

Being optimistic may have a protective effect on stroke because of the behavior choices optimistic people tend to make, such as exercising, eating a healthy diet, or taking vitamins, the researchers say. However, some evidence indicates positive thinking may have a strictly biological effect as well.

More studies are needed to further understand the mechanisms that facilitate the protective role of optimism on stroke, the researchers write. They note that twin studies show that only a portion of optimism is genetic.

They also suggest that if further research continues to point to the protective role of optimism against stroke, then there is a need for further research to assess how "optimism interventions" can supplement current "stroke protocol."
