Air pollution linked to silent strokes
Conclusion This cross-sectional study has suggested a link between exposure to small particles in the air (one form of pollution) and the presence of "silent stroke" in older adults – small areas of damage to the brain tissue that are not severe enough to cause obvious symptoms. There are a number of limitations to be aware of when assessing the results of this study: While there was an association between particulate matter in the air and total brain volume, this was no longer statistically significant after taking into account whether people have conditions such as high blood pressure, which can also affec...

Claims magnetic brain stimulation helps memory
ConclusionIn this study, TMS was found to improve performance on the associative memory test by more than 20%, whereas sham stimulation had no significant effect.TMS also increased connectivity between specific cortical (grey-matter) regions of the brain and the hippocampus.This interesting research increases our knowledge of how memory works. However, it was a very small trial with only 16 participants. It is also unclear whether electromagnetic stimulation would be effective for people with memory disorders such as dementia. The media has reported that the researchers are now planning to study the effect of TMS on people...
