You may be prescribed Pramipexole, which is essentially a dopamine agonist drug, should you be diagnosed with Parkinson’s disease (PD) or restless leg syndrome (RLS). As with far too many pharmaceuticals the drug isn’t topical in that it bathes the brain in order to affect specific receptors. It also has side-effects. Neurobiologist David Anderson calls this the ‘bag of chemicals’ approach to treatment.
What science hopes to do in the future (apparently the only place where great things happen) is target receptors. How is he and his team figuring out how to do this? With fruit flies.
