FDA Approves Brain Test for ADHD
The U.S. Food and Drug Administration on Monday approved the first brain test that could help doctors diagnose attention-deficit hyperactivity disorder (ADHD) using biological evidence, and not just the results of psychiatric evaluations.
The device, called the NEBA System, is a 20-minute test that uses an electroencephalogram (EEG) test to look at a patient's brain waves. Specifically, it measures the ratio between beta and theta brain wave frequencies, which studies have shown is higher in children and teens with ADHD.
"Diagnosing ADHD is a multi-step process based on a complete medical and psychiatric exam," Christy Foreman, director of the Office of Device Evaluation at the FDA's Center for Devices and Radiological Health, said in an agency statement. "The NEBA System, along with other clinical information, may help health care providers more accurately determine if ADHD is the cause of a behavioral problem."
The test is already used to assess sleep issues, measure unconsciousness, diagnose side effects from head injuries and monitor the brain during surgery, according to CBS News.
A company-funded study of almost 300 kids and teens with behavior problems showed that the test, when coupled with standard diagnostic criteria, helped physicians more accurately diagnose the disorder than a doctor's exam alone.
ADHD affects nearly 7 percent of kids between the ages of 3 and 17, and a recent government report found that 11 percent of all school-aged children have been diagnosed with the disorder, the FDA statement said.
More Cases of Rare Foodborne Infection Reported in Iowa
Fifteen more infections from a rare, food-born parasite have been reported in Iowa, bringing the total number to 60, state officials said.
Nebraska has had 35 cases of infection caused by cyclospora, which causes severe diarrhea. It's believed that the parasite came from vegetables, but investigators haven't determined which kind, the Des Moines Register reported.
It's likely that whatever vegetables caused the outbreak -- which began in mid-June -- have been sold and consumed or thrown out, according to officials. However, they reminded people to carefully wash their produce and said cooking should kill the parasite.
Vegetables from home gardens should be safe, authorities said.
In the previous 20 years, there have been 10 confirmed cyclospora cases in Iowa, the Register reported. The infection can be treated with antibiotics.
'Glee' Actor Cory Monteith Found Dead in Canadian Hotel
Foul play has been ruled out in the death of Cory Monteith, a lead actor on the television show "Glee."
He was found dead in a Vancouver hotel room on Saturday. The cause of death was not immediately apparent, but police said it was not foul play. An autopsy on the 31-year-old Canadian actor will be conducted Monday, CNN reported.
Police said that Monteith's body was discovered by staff members at the Pacific Rim Hotel after he missed his checkout time. He had checked in on July 6.
Monteith had several people over to his room at one point Friday night but was seen on hotel surveillance video returning to his room in the early morning hours by himself, acting Chief Constable Doug LePard told reporters, CNN reported.
