Hi: Well, just out of curiosity I picked up a copy of "Smart Drugs & Nutrients." I was curious because it describes a lot of the "folklore" drugs used to treat PD. I thought that some of you might be interested in seeing the glossary entry for dopamine: --------------------- --------------------- "A neurotransmitter critical to fine motor coordination, immune function, motivation, insulin regulation, physical energy, thinking, short term memory, emotions such as sexual desire, and autonomic nervous system balance." --------------------- --------------------- Wow! If I had known this, I would have taken better care of my substantia nigra. I've been watching this listserver for about a year and doing a lot of informal research and am somewhat surprised by some of these items such as "immune function", "motivation" and "insulin regualtion". I wonder what the source is for their definition. Incidentally, the book has an appendix devoted to the laws concerning importation of "orphan drugs" (i.e., drugs approved for use by regulatory agencies in other countries but not in the USA." Most of these smart drugs are orphan drugs because their developers could not prove that they are effective against any specific medical malady. Ron Reiner
