Answer:Magnesium plays an important role in brain cell function and some preliminary research in animals has suggested it may influence cognitive functions like memory and learning.
Increasing magnesium intake may improve cognition in older people who otherwise have a high ratio of calcium to magnesium intake.
A preliminary study in people found that magnesium-L-threonate (Magtein or Clarimem) modestly improved limited aspects of cognitive function. Another study of magnesium-L-threonate in people with dementia was completed in mid-2016 but the results have not been published.
