First of all, I am so happy that you are back stronger on bashing on the medical establishment!
IMHO the dopamine replacement/enhancement therapy has reached it's limits and the numerous new drugs did not make a big difference since the discovery of l-dopa/carbodopa.
The only break through in my opinion was DBS, which holds promise if it is refined and developed to non invasive version by avoiding the necessity to drill holes in the brain and I remember that some research was conducted with externally stimulating the peripheral nerves.
The other thing I believe in is what Paula said "they need to dig deep and find out whether we have our own capability" to self heal and helping our brains to compensate.
God bless
