Hi Again Just wanted to add a little more personal data in my research into PD dyskinesia . I have used sugar/glucose to lessen the effects of end of dose( L-dopa ) dyskinesia . I believe it does it by boosting one again into the "on " state , by increasing the glucose level in the brain . Later on one gets a combined dropping level of glucose and dopamine in the brain so one drops through the danger zone quickly and with little dyskinesia . I use sugar to boost me out of beggining dose dyskinesia ie to boost me into the " on " state if the L-dopa is struggling to get me there . I have also used GHB to succesfully stop end of dose dyskinesia . Its action is not too well understood but it is reputed to drop the dopamine level in the brain . Yesterday I tried L-pyroglutamic acid and I got dyskinesia without taking any L-dopa ! This could be explained by the acid boosting the dopamine level to the dyskinetic level . More research required here . I t might be that this acid just increases the chance of dyskinesia I think stress has this effect . It is self perpetuating . The dyskinesia causes stress which in turn aggravates the dyskinesia . I find it very similar to asthma spasm in this respect . I have also used the electronic stimulation of a TENS machine to alleviate end of dose dyskinesia . I explain this by suggesting that the TENS machine stimulation pattern is interferring with the brain pattern to lessen the spasm . I believe PD to be a neuron brain firing spasm . At present I am trying so many different chemicals that it difficult to sort out what is doing what . ( most do nothing ) peace Alastair ( [log in to unmask] )
