Somewhere between 8.15 P.M. and 9.15 P.M. my wife experiences gut wrenching dyskensia for 15 minutes to half and hour. She had much longer shaking periods until we finally found a pill regime that would keep the time to a minimum. This situation is not unusual. In the "Algorithm for Managing Parkinson's Disease" they have this to say "After the last dose, however, patients will cycle through the dyskinetic phase but at a relatively predictable time. Thus they can arrange to be at home and perhaps self administer a mild, short acting tranquilizer such as alprazolm...." (We want stay away from tranquilizers if at all possible) For the first 16 years she did not have any appreciable problems in the evening. It is really only in the last two and a half years that the dyskensias became so bad. It breaks my heart to see her going through such agony. This is her present regime:8:30 AM Sinemet CR,10:30 AM 0.25*25/100 reg sinemet 2.5 mg deprenyl,12.30PM Sinemet CR,3:30PM Sinemet CR, 6:30PM 0.5*25/100 reg sinemet,8:30PM 0.25*25/100 reg sinemet. My wife is at the stage where the dopamine in her brain tracks the levadopa in here bloodstream quite closely. Since this is a common phenomena, someone somewhere must have done some research on trying to beat this aspect of Parkinsons. So what I am asking is for help in finding papers involving research on this aspect of Parkinsons (or maybe one of the members of the list has already found the answer.)
