EAST LANSING, Mich. — Health professionals may soon have a new method of diagnosing Parkinson’s disease, one that is noninvasive and inexpensive, and, in early testing, has proved to be effective more than 90 percent of the time.

In addition, this new method has the potential to track the progression of Parkinson’s, as well as measure the effectiveness of treatments for the disorder, said Rahul Shrivastav, professor and chairperson of Michigan State University’s Department of Communicative Sciences and Disorders and a member of the team developing the new method.

It involves monitoring a patient’s speech patterns – specifically, movement patterns of the tongue and jaw. (more…)

Anxious Women’s Brains Work Harder

EAST LANSING, Mich. — In a discovery that could help in the identification and treatment of anxiety disorders, Michigan State University scientists say the brains of anxious women work much harder than those of men.

The finding stems from an experiment in which college students performed a relatively simple task while their brain activity was measured by an electrode cap. Only women who identified themselves as particularly anxious or big worriers recorded high brain activity when they made mistakes during the task.

Jason Moser, lead investigator on the project, said the findings may ultimately help mental health professionals determine which girls may be prone to anxiety problems such as obsessive compulsive disorder or generalized anxiety disorder. (more…)
