Sleep: the Brain’s Reset Button

  Recently, psychiatry professors Giulio Tononi and Chiara Cirelli published an article outlining their hypothesis on the purpose of sleep and how it affects memory and learning.  They point out that all living animals require sleep, from humans to fruit flies. Dolphins and whales even sleep by turning off one hemisphere of their brain at a time, which allows them to still surface to breathe. But what benefit could sleep provide that outweighs leaving one weak and vulnerable? Nearly a century ago, scientists proposed the idea that sleep is important to memory. Many believed, and a myriad of studies have shown, that newly formed memories are remembered more strongly...

The Potential Benefits of Vitamin D

  Research was recently presented at the 5th Cooperative Meeting of the Consortium of MS centers (CMSC) and the Americas Committee for Treatment and Research in MS (ACTRIMS), which suggests vitamin D can potentially benefit multiple sclerosis patients who are currently receiving therapy. Genes associated with increased vitamin D levels, as well as interferon b-1b, are associated with a decrease in gadolinium-enhancing lesions (Gd+, a type of lesion commonly found in MS patients). A clinical trial known as the BENEFIT* study, examined the safety and effectiveness of early interferon b-1b treatment in patients at risk for developing MS. During this study, researchers also examined patients’ vitamin D levels to...

PML and the Anti-JCV Antibody

  For MS patients considering using Tysabri as a treatment method, the risk of developing PML is a serious concern. PML is a disease caused by a viral infection, which affects the white matter of the brain. The instigating virus in PML is called Polyomavirus JC, more commonly known as the JC virus (JCV). In the majority of people the JC virus causes little to no harm, and it is only in people suffering from weakened immune systems that the virus seems to trigger PML. PML usually occurs in patients undergoing corticosteroid or immunosuppressive therapy.1 Tysabri treatments have been shown to result in the development of PML in a...
