This results in inflammation and injury to the sheath and ultimately to the nerves that it surrounds. The result may be multiple areas of scarring (sclerosis). Event...

Understanding of Schizophrenia Could Lead to New Treatment Options

... fewer branches and formed a significantly thinner myelin sheath around nerve fibers. As a result, the nerve fibers conducted electrical impulses more slowly, the researchers found. The mice also had changes in the nerve cells that make and use dopamine, a key chemical in the brain that transmits messages...

Different Approach Needed to Protect Brains of Premature Babies

...ollow-up studies of axons before they're coated in myelin and of potential protective compounds. "This model turns out to be a powerful tool for seeking out and testing new drugs, so we want to test a number of new pharmaceuticals to see if any can protect axons early in brain development," Goldberg say...

Could Estriol Be Used as a Therapy for Treating MS?

...lation wrapped around an electrical wire. When the myelin is damaged, the nerve’s ability to send signals to and from the brain is interfered with, resulting in symptoms common to MS, including problems with balance, memory, vision loss and more. Currently, anti-inflammatory drugs used to treat MS lessen ...
