Some studies suggest that vitamin B supplements may increase the risk of stroke and heart attack. However, a new review published in the journal Neurology discovered the opposite. Researchers analyzed the findings of 14 clinical trials which compared taking vitamin B supplement or very low-dose vitamin B versus placebo for six or more months. They discovered that vitamin B supplements may reduce the risk of stroke by 7 percent, but did not appear to reduce the severity of strokes or the risk of death from stroke. The researchers also found that folic acid may reduce the beneficial effect of vitamin B. How often do patients ask you about vitamin B supplements? Do you recommend vitamin B for other conditions?

A longitudinal observational study published in the journal Neurology associated exercise in the late 70s with the reduction of brain shrinking. Researchers at Edinburgh University concluded that physical activity was associated with less atrophy and white matter lesion. These findings suggest that exercise may be neuro protective and lead to a decrease in cognitive decline. How much exercise do you recommend to your patients on a daily basis? How do you think this information will affect the elderly population at risk of dementia?
