Deficiencies in many of the B vitamins results in negative cognitive effects (see Consequences of Select Micronutrient Deficiencies), and a number of studies have linked lower blood levels of B vitamins with some cognitive impairments (147-154)
At the same time, although excitatory amino acids have no obvious effect, there is a decreasing trend, which can inhibit the expression of excitatory amino acid receptors, thereby weakening excitatory signal transduction and ultimately alleviating neurotoxicity
