A combination of tests may be the best way to diagnose Alzheimer's disease early.

Doctors at Duke gave patients an MRI and PET scan. They also took spinal cord fluid to look for genetic markers.

Researchers found this approach was more accurate at detecting Alzheimer's then current methods like memory tests and physical exams.

They admit the battery of tests is expensive and more study is needed to confirm the findings.

Another study finds too much television can increase a child's risk of obesity and doctors say a TV in the bedroom can make it even worse.

The new research finds kids with a TV in their room are three times more likely to be overweight.

Researchers say it's likely the TV keeps kids from getting enough sleep - which can also increase the risk of obesity.

Active women live 3 years longer on average.
