Isradipine slows and might stop Parkinson's disease

Drug Slows And May Halt Parkinson's Disease ScienceDaily 6/12/07 "...The drug rejuvenates aging dopamine cells...D. James Surmeier, the Nathan Smith Davis Professor and chair of physiology at Northwestern University's Feinberg School of Medicine, and his team of researchers have found that isradipine, a drug widely used for hypertension and stroke, restores stressed-out dopamine neurons to their vigorous younger selves. The study is described in a feature article in the international journal Nature, which will be published on-line June 10...Isradipine may also significantly benefit people who already have Parkinson's disease. In animal models of the disease, Surmeier's team found the drug protected dopamine neurons from toxins that would normally kill them by restoring the neurons to a younger state in which they are less vulnerable...When he gave the mice isradipine, it blocked the calcium from entering the dopamine neuron. At first, the dopamine neurons became silent. But within a few hours, they had reverted to their childhood ways, once again using sodium to get their work done. ..."This lowers the cells' stress level and makes them much more resistant to any other insult that's going to come along down the road. They start acting like they're youngsters again," Surmeier said... "

Steve - caught this tonight. You might know about it already - seems promising. Maybe Isradipine would help with your dad.
