Carol, In the reactions on he constipation subject, I missed something. One of the primary symptoms of PD is slowing down of the activities of the intestines. Dopamine has more tasks than the regulation of motor behaviour. All our muscles are divided into two classes: the striated and the smooth. The striated are involved in conscious movement. The fine tuning of movement is the task of the extra-pyramidal system which for PWP's is invalidated by loss of dopamine. Our organs have smooth muscles and their movement is beyond direct control, but dopamine has something to do with it. The organs are ruled (activated or not) by two systems which are the sympatheic and the parasympathetic. Being afraid or angry or highly concentrated on a task makes the sympath. active, which results in a set of effects that is known as the flight-or-fight reaction. Among others the blood is taken away from the viscera and transported to the striated muscles so a fight or flight is made possible. The parasymp. does the opposite. A greater part of blood is brought to the viscera. In short the sympathetic systems is for defending oneself and earn a living. and the parasympathetic one for consuming and procreation and elimination The most important neurotransmitters of the parasympathetic systems are acelylcholine and dopamine. That is why parasympathetic functions are damaged in PWP's Sexual arousal is for some PWP's only fully possible when the sinemet is active. Urine retention is a Park. symptom and so is slowing down of the digestive track and difficult elimination. To what extent each symptom shows up in a PWP is for all symptoms variable. Of course knowing this is not bringing a solution but Carol Hilton advised us well on this list. BTW My personal solution for this problem is eating a few dates every day.
