Whatever its cause, the best way to control Parkinson's is to treat it as soon as a diagnosis is made -- usually after the onset of tremors and walking difficulties. But that can be too late, according to Dr. Hubert Fernandez at the Cleveland Clinic.
"By this time, though, a considerable amount of degeneration has already occurred in the brain," Fernandez explained. "Ideally, we would like to have a test that is specific for Parkinson's disease. And, ideally, we would like to have that test become positive even before we see the shaking.
There's currently no such test for Parkinson's, but at Northwestern University, researchers think they might have found a way to slow its progression.
"We looked at the cells in the brain that were most vulnerable to the disease. What we saw was they allowed lots and lots of calcium into their cell bodies," said Jim Surmeier, Physiologist who spoke to VOA by Skype.
The calcium eventually killed dopamine-producing cells and triggered Parkinson's symptoms. But the Northwestern University scientists found a drug that limits the brain cells' uptake of calcium, without harmful side effects. In a Skype interview, co-researcher Tanya Simuni told VOA another clinical trial is being planned. "The primary question to be answered in this study is whether the drug is effective in slowing the progression of Parkinson's disease disability," she said.
Current drugs used to control the tremors and walking difficulties work well for about five to ten years. If scientists could develop a new therapy that could double or triple that time, it would enable Sarah Taylor and the ten million other people living with Parkinson's disease around the world to lead much more normal lives.
