The relation of hydration status to cognitive performance in healthy older adults

Consistently with former studies performed in younger adults, the findings by Suhr et al.  emphasize the importance of considering poor hydration as a contributor to impairment in cognition in older adults, even at relatively mild levels. Those findings should now be replicated with larger and more diverse sample of older adults. Further studies might also determine whether hydration status enhancement leads to improvement in cognitive performance in older adults.
