Federal study for Alzheimer's drug

There's new hope for treating Alzheimer's in the future. A federally funded study will take a look at a drug designed to help clear sticky deposits in patient's brains.

Earlier studies showed it had some promise if the condition was caught early.

Researchers think it will work even better if they can get it to people before the symptoms start.

The study involved 1,000 people aged 70 to 85.
