The next research has come from Harvard University. They are optimistic in that it may be possible to halt the advance of Huntington's by injecting drugs that block the NMDA-receptor so that calcium can not get into cells. In animal models, experiments have shown that this receptor block can keep brain cells from dying. Harvard researchers are seeking approval for clinical trial that will test such neuroprotective drugs on patients with symptoms of the disease. This is a very promising research direction.
