Sleep Disorders Widely Undiagnosed in Individuals with Multiple Sclerosis

 
In what may be the largest study of sleep problems among individuals with multiple sclerosis (MS), researchers at UC Davis have found that widely undiagnosed sleep disorders may be at the root of the most common and disabling symptom of the disease: fatigue.

Conducted in over 2,300 individuals in Northern California with multiple sclerosis, the large, population-based study found that, overall, more than 70 percent of participants screened positive for one or more sleep disorders.

The research highlights the importance of diagnosing the root causes of fatigue among individuals with MS, as sleep disorders may affect the course of the disease as well as the overall health and well-being of sufferers, the authors said.

Where Original Ideas Come From

Revolutions are seldom solo efforts.  Isaac Newton was the greatest scientist of his age and not one known for his false modesty, but even he had to admit, "If I have seen further it is by standing on the shoulders of giants."

Thomas Kuhn made a related point in his classic, The Structure of Scientific Revolutions.  He argued that precedence in science is somewhat arbitrary—a matter of perspective rather than fact—because new discoveries are rarely tied to the work of just one person or team.

Yet, while very few ideas are truly original, there are exceptions.  Sometimes an important new idea seems to have no precursor or precedent, but springs forth whole from a single mind and completely alters our perception of how the world works.  Although these are rare, they have a lot to teach us about how to become more creative ourselves.
