  • Stem Cells

Researchers experimenting with rats say Embryonic Stem Cells can relieve symptoms of Parkinson's Disease. The researchers found early-stage cells can be turned into nerve cells that make the brain chemical dopamine. People suffering from Parkinson's Disease are lacking in Dopamine. The senior author of the study is from the Harvard-Affiliated McLean Hospital. He says the technique could be ready to experiment on people within five years. The study can be found in "Proceedings of the National Academy of Sciences."

  • Can You Catch Heart Disease?

A new study shows a link between infection and Heart Disease. It's raising some medical eyebrows because previous studies have shown no connection between infection and thickening of the arteries. According to this new report in the journal, "Circulation," researchers studied 500 patients with Heart Disease. All were tested for both viral and bacterial infections and were followed for three years. In the end, they found the death rate to be consistently higher among patients with the most infections. Researchers say the link could be there because the immune system fights infection with inflammation. More study is needed.

  • Immune Attention Deficit Hyperactivity Disorder

Don't we all find behaviors in kids that are similar to a parent? Who either gets the blessing or the blame. That may be more true now for behavior disorders like Attention Deficit Hyperactivity. Researchers have uncovered a new genetic risk factor for that. It's a gene called I-L One, which helps regulate a part of the immune system that protects the brain from stress. New research suggests that kids born with a variation of the gene may be at higher risk for behavior disorders like ADD.

Several studies have shown the disorder can be inherited, but until now researchers have focused on genes that may help control it, not cause it. Researchers say this new finding may help lead to better treatments. Attention Deficit Hyperactivity Disorder affects 4% to 10 % of school age children. The study is the Journal, "Molecular Psychiatry." Studies show I-L One also plays a role in brain development and has been linked to depression
