Health News : Genes Related to Alzheimers and Liver Damage for Alli Users


Scientists make what many health experts say is the biggest genetic discovery in Alzheimer's disease in more than 15 years.

A team of scientists has discovered two new genes related to the most common form of Alzheimer's disease. The researchers pooled DNA samples from more than 16,000 people.

Up until now, only one gene had been identified as a risk factor for late-onset Alzheimer's.

They also pinpointed 13 other variants which might be related.

A separate study discovered a third gene.

The findings could lead to new treatments for the disease. They're published in Nature Genetics.


There's a new health warning about the popular over-the-counter weight loss drug, Alli.

The Food and Drug Administration is investigating more than 30 reports of liver damage of people taking Alli, and the prescription version, Xenical.

Six of those cases resulted in liver failure.

But for now, the FDA recommends patients continue taking the drug as directed.

To be fair, Alli and Xenical's maker says more than 30,000 patients were studied in 100 clinical studies and it has found no evidence the drug causes liver injury.
