Where Science Meets Society

Study links nutrition to brain health and cognitive aging

A new study of older adults finds an association between higher blood levels of phosphatidylcholine, a source of the dietary nutrient choline, and greater cognitive flexibility, the ability to regulate attention to manage competing tasks. The study also identified a brain structure within the prefrontal cortex, a region at the front of the brain, that appears to play a role in this association.

 

Study finds brain markers of numeric, verbal and spatial reasoning abilities

A new study begins to clarify how brain structure and chemistry give rise to specific aspects of “fluid intelligence,” the ability to adapt to new situations and solve problems one has never encountered before.

The study, reported in the journal NeuroImage, links higher concentrations of a marker of energy production in the brain with an improved ability to solve verbal and spatial problems. It also finds an association between brain size and number-related problem-solving.
