A new iPad application may help doctors diagnose and treat multiple sclerosis.
The test takes about five minutes and measures how quickly a person can figure out the answer to a series of simple problems.
The results can be interpreted almost immediately and placed in the patient's medical record.
Some doctors believe a slower time result could help expose MS-related brain dysfunction.
"We have found that the app is just as reliable and valid as the paper and pencil tests that require a technician to be present when the test is administered,” said Dr. Stephen Rao of the Cleveland Clinic.
The app will be unveiled today at the "American Academy of Neurology's" annual meeting.
It could be ready for clinical use by next year.
