Where you live and spend time may play a powerful role in cognitive health, according to a new report. The findings add to growing evidence that environmental factors like exposure to air pollution or access to parks can affect the risk of developing Alzheimer’s disease or other forms of dementia. For the analysis, researchers reviewed dozens of studies that looked at the effects of our environment on cognitive health and the risk of dementia. By pooling data from multiple studies, they quantified how much various environmental factors could increase or decrease the risk of cognitive decline and dementia. https://www.alzinfo.org/articles/prevention/how-your-surroundings-may-affect-your-alzheimers-risk/ (fb)

Green tea, a traditional beverage in Asia that has become increasingly popular in the United States in recent years, may be good for the brain, according to a new report. While sipping green tea won’t guarantee you won’t develop Alzheimer’s disease or slow its progression, it could lower your risk, the findings suggest. The study, from researchers in Japan, found that older adults who regularly drank three or more glasses of green tea a day had fewer brain abnormalities known as white matter lesions. White matter is the part of the brain that supports and connects neurons, the nerve cells that allow us to think and remember. https://www.alzinfo.org/articles/prevention/three-glasses-of-green-tea-a-day-for-brain-health/ (fb)
