We’re researching how businesses can engage people with dementia meaningfully and respectfully in the design, testing, and commercialization of apps intended for their use. For this research, we’re looking for people living with dementia to use, test, and provide feedback on a digital memory aid currently being developed. Follow the link for more information.
Drinking tea improves short-term attention and concentration; it is possible that tea could also benefit long-term cognitive health through its antioxidant and anti-inflammatory properties. In a recent study from the University of Singapore, researchers collected baseline tea-drinking and lifestyle data from 957 participants aged 55 and above from 2003-2005 and followed up between 2006 and 2010. They found that drinking tea on a daily basis was correlated with a reduced risk of developing dementia, even when controlling for other lifestyle factors such as diet, exercise, smoking, and presence of other diseases. The neuroprotective effect was present in a dose-dependent manner with consumption of green, black, and oolong tea. Drinking tea offered greater resistance against cognitive decline in women and in carriers of the APOE e4 gene, which could have implications for personalized medicine in the future. Protection against cognitive decline is important all older adults, as even people that age normally experience a degree of cognitive decline. Researcher Lei Feng explains that “tea is one of the most widely consumed beverages in the world. The data from our study suggests that a simple and inexpensive lifestyle measure such as daily tea drinking can reduce a person’s risk of developing neurocognitive disorders in late life,” adding that “[their] understanding of the detailed biological mechanisms is still very limited so [they] do need more research to find out definitive answers.”
