A new study of 3000 European men aged 40-79 evaluated the impact of Vitamin D on cognitive performance and found a significant improvement on information processing, particularly as individuals aged, when they received a plethora of vitamin D.

The main sources of Vitamin D synthesis include sunshine and certain oily fish. Information processing and speed may have a variety of health-related implications...

A new study by Swedish researchers asserts that cognitive speed declines much earlier and more rapidly than previously had been understood by most scientists, and faster than perceptual acuity and vocabulary.

The Gothenburg University study led by Valgeir Thorvaldsson followed the subjects over a 30 year period. Of three topical areas - cognitive speed, perceptual ability, and verbal ability - cognitive speed was the mental factor that was impacted the earliest.

In Jensen's estimation, this was defined as 'nerve conduction velocity.' One might conclude based on the plentiful supporting results that this ability is the most reliable indicator of impending cognitive impairment.
