Drinking tea improves brain health

Older people who drink tea at least four times a week have better brain efficiency than those who don't, a new neuroimaging study reveals. Drinking tea is associated with better cognitive function in older people. Researchers report the study provides evidence that tea consumption has protective effects against age-related decline in brain organization.

‘Superagers’ over 80 have the memory and brain connectivity of twenty-somethings

Both the default mode network and salience network in superagers had stronger connectivity than typical older adults and similar connectivity as younger adults. Superagers performed similarly to young adults and better than typical older adults in recognition and episodic memory tasks.
