MS is a chronic disease of the brain and spinal cord, usually with recurrent flare-ups of symptoms. It is often preceded by a first episode (or event) of similar symptoms lasting days to weeks.
When a laboratory rat learns how to reach for and grab a food pellet – a pretty complex and unnatural act for a rodent – the acquired knowledge significantly alters the structure of the specific brain cells involved, which sprout a whopping 22 percent more dendritic spines connecting them to other motor neurons.

Registration is now open to journalists planning to attend the 63rd Annual Meeting of the American Academy of Neurology (AAN) in Hawaii, April 9–16, 2011. The AAN Annual Meeting is the world’s largest gathering of neurologists who come together to share the latest advances in neurologic research.
Philip Schatz Ph.D., professor of psychology, and his associates recently published a study in Neurosurgery that identifies potentially enduring effects of multiple previous concussions on high school students. More specifically, Schatz and his colleagues propose through their research that teens with multiple concussions may already be demonstrating early signs of post-concussion syndrome.
Among stem cell biologists there are few better-known proteins than nestin, whose very presence in an immature cell identifies it as a "stem cell," such as a neural stem cell. As helpful as this is to researchers, until now no one knew which purpose nestin serves in a cell.

An influential article in the journal Progress in Neurobiology provided one of the first comprehensive reviews of how estrogen potentially can protect against Alzheimer's disease and other neurological disorders.
Researchers have found the brain region responsible for allowing our brains to ignore background motion in favor of the motions of objects in the foreground. Interestingly, the elderly and people with schizophrenia and depression don't prioritize in this way.
In the wake of recent reports of long-term health effects of repeated concussions in professional athletes, a new study finds increased rates of concussion-related symptoms in high-school athletes with a history of two or more previous concussions. The study will appear in an upcoming issue of Neurosurgery, official journal of the Congress of Neurological Surgeons. The journal is published by Lippincott Williams & Wilkins, a part of Wolters Kluwer Health

Much of our knowledge of the brain’s role in regulating breathing comes from research with mice and rats. A chemical receptor within the brain stem communicates with the central nervous system to generate the basic pattern of breathing. The next step is applying that information to human tissue to identify these critical components in the human brain and their medical implications.
Darryl Kaelin, M.D., is the medical director for the Acquired Brain Injury Program at Shepherd Center in Atlanta. He oversees Shepherd Center's medical treatment and specialized rehabilitation care programs for people with acquired brain injury.
While the overall hospitalization rate for stroke has declined in recent years, the numbers have jumped dramatically for patients infected with human immunodeficiency virus (HIV), suggesting they may be up to three times more likely to suffer a stroke than people uninfected by the virus that causes AIDS.
New research suggests that people infected with human immunodeficiency virus (HIV) may be up to three times more likely to have a stroke compared to those not affected with HIV.

Scientists from the Monell Center and collaborators report that two structurally unrelated anti-inflammatory compounds both activate the TRPA1 receptor. One, oleocanthal, is found in extra virgin olive oil while ibuprofen is an over-the-counter non-steroidal anti-inflammatory drug (NSAID). The findings may provide novel insights into anti-inflammatory pharmacology.

Mutant presenilin is infamous for its role in the most aggressive form of Alzheimer’s disease—early-onset familial Alzheimer’s—which can strike people as early as their 30s. In their latest study, researchers at the Salk Institute uncovered presenilin’s productive side: It helps embryonic motor neurons navigate the maze of chemical cues that pull, push and hem them in on their way to their proper targets. Without it, budding motor neurons misread their guidance signals and get stuck in the spinal cord.
Researchers at the University of North Carolina at Chapel Hill have discovered a molecule that can make brain cells resistant to programmed cell death or apoptosis.
Parkinson’s disease symptoms begin subtly and worsen as damage to certain brain cells continues. But an electrical stimulation device implanted deep in the brain, along with medications, may provide some control of symptoms such as shaking, stiffness, and loss of muscle control. But what happens if the drugs are stopped and the device is switched off after five years? Are the symptoms far worse than they were to start, as might be expected ? Surprisingly, no, says neurologist Michele Tagliati, M.D..
A new guideline from the American Academy of Neurology recommends using plasma exchange to treat people with severe relapses in multiple sclerosis (MS) and related diseases, as well as those with certain kinds of nerve disorders known as neuropathies.
