Problems

A study involving 187 children and adolescents with multiple sclerosis, plus 44 who experienced their first neurologic episode (clinically isolated syndrome) indicative of MS, has found that 35% of those with MS and 18% of those with clinically isolated syndrome were cognitively impaired. Cognitive assessment was done using a battery of 11 tests. The most common areas of impairment were fine motor coordination, visual-motor integration, and speeded information processing.

New findings support a mathematical model predicting that the slow, steady firing of neurons in the dorsolateral prefrontal cortex that maintains visual representations in working memory relies on a class of NMDA receptors known as NR2B receptors. Blocking these receptors abolished persistent firing among pyramidal Delay cells.

It certainly sounds like pseudo-science, but that's why we do science - because the weirdness of something is not a particularly good reason to dismiss it (quantum! many-universes!). Sometimes we don't understand enough about how things work to know why they work, but finding out whether or not they work is a good place to start.
