Health Alert: New early detection of Alzheimer's

(CBS) - Researchers at Johns Hopkins believe they may be able to spot Alzheimer's years before memory loss begins.

The study found people with certain proteins in their spinal fluid have a higher chance of developing the disease.

Scientists hope their discovery will lead to a test, so doctors can treat patients early and possibly prevent the disease.

(CBS) - Autism cases appear to be leveling off in Britain. 

A study in the British Medical Journal says about 1 in every 250 kids has autism. A rate that's held steady for the past few years. 

That's much lower than the U.S. where government numbers show about one in 88 children have the disorder.

(CBS) - A study in the journal Nature finds different types of cancers share the same genetics.

Scientists analyzed more than 3,000 tumors and discovered a handful of common mutated genes. 

For example, a mutation in many leukemia cases was also found in breast, kidney, lung and ovary cancer tumors.

Doctors say the discovery could one day lead to treatments that target these mutations.
