Dyskinesia
Ron-
I've been scratching around for a couple of hours and found nothing to make me wonder about either curcumin or citicholine. Research is sparse, but I did find a promising few old friends and I'll list them individually. -Rick |
Dextromethorphan for dyskinesia
In true white rat fashion, I am testing this one even as we type. It is presently 4:18 PM here and I've been dyskinetic for the last couple of hours and expect to be so for a couple more. So, I took a quarter teaspoon at 4:15 and will report later.
1. Mov Disord. 1998 May;13(3):414-7. A trial of dextromethorphan in parkinsonian patients with motor response complications. Verhagen Metman L, Blanchet PJ, van den Munckhof P, Del Dotto P, Natté R, Chase TN. Experimental Therapeutics Branch, National Institute of Neurological Diseases and Stroke, National Institutes of Health, Bethesda, Maryland 20892-1406, USA. The effects of the NMDA antagonist dextromethorphan (DM) on levodopa-associated dyskinesias and motor fluctuations were studied in patients with advanced Parkinson's disease. During initial open-label dose escalation, 6 of 18 patients reported a beneficial effect at their individually determined optimal DM dose (range, 60-120 mg/day). The 12 remaining patients either experienced reversible side effects, particularly mild drowsiness, or decreased levodopa efficacy, and were therefore excluded from the study. The six responders entered the double-blind, placebo-controlled, crossover study with two 2-week arms separated by 1 week wash-out. On the last day of each arm, motor ratings were performed every 20 minutes for 8 consecutive hours. In addition, motor complications and Activities of Daily Living (ADL) were assessed using the Unified Parkinson's Disease Rating Scale (UPDRS) and patient diaries. With DM, dyskinesias improved by 25% according to physician's ratings and by 40% according to UPDRS interviews, without compromising the anti-Parkinson effect of levodopa. Motor fluctuations and ADL scores also improved significantly. Although the narrow therapeutic index of DM limits its clinical usefulness, these findings support the view that drugs acting to inhibit glutamatergic transmission at the NMDA receptor can ameliorate levodopa-associated motor complications. PMID: 9613730 [PubMed - indexed for MEDLINE] 1. Amino Acids. 1998;14(1-3):75-82. Blockade of glutamatergic transmission as treatment for dyskinesias and motor fluctuations in Parkinson's disease. Verhagen Metman L, Del Dotto P, Blanchet PJ, van den Munckhof P, Chase TN. National Institute of Neurological Diseases and Stroke, National Institutes of Health, Bethesda, Maryland, USA. In animal models of Parkinson's disease (PD), glutamate antagonists diminish levodopa (LD)-associated motor fluctuations and dyskinesias. We sought to investigate if these preclinical observations can be extended to the human disease, by evaluating the effects of three non-competitive NMDA antagonists (dextrorphan, dextromethorphan and amantadine) on the motor response to LD in patients with advanced PD. In four separate trials, adjuvant therapy with these drugs reduced LD-induced dyskinesias and motor fluctuations. These findings support the view that drugs acting to inhibit glutamatergic transmission at the NMDA receptor can ameliorate LD associated motor response complications. PMID: 9871445 [PubMed - indexed for MEDLINE] 1. Neurology. 1998 Jul;51(1):203-6. Dextromethorphan improves levodopa-induced dyskinesias in Parkinson's disease. Verhagen Metman L, Del Dotto P, Natté R, van den Munckhof P, Chase TN. Experimental Therapeutics Branch, National Institute of Neurological Diseases and Stroke, National Institutes of Health, Bethesda, MD 20892-1406, USA. OBJECTIVE: This study assessed the effects of the N-methyl-D-aspartate (NMDA) antagonist dextromethorphan (DM) on levodopa-induced dyskinesias in Parkinson's disease (PD). BACKGROUND: Recent experimental evidence suggests that increased synaptic efficacy of NMDA receptors expressed on basal ganglia neurons may play a role in the pathophysiology of levodopa-induced motor response complications. METHODS: DM was given to six PD patients with motor fluctuations in a double-blind, placebo-controlled, cross-over study. At the end of each 3-week study arm, patients received several brief i.v. levodopa infusions while parkinsonian symptoms and dyskinesias were frequently scored. Levodopa dose-response curves for antiparkinsonian and dyskinetic effects were then compared for each study arm. RESULTS: With DM, average and maximum dyskinesia scores improved by >50%, without compromising the antiparkinsonian response magnitude or duration of levodopa, although in some subjects the levodopa threshold dose was slightly higher with DM than with placebo. CONCLUSIONS: These findings support the view that drugs acting to inhibit glutamatergic transmission at the NMDA receptors can ameliorate levodopa-associated dyskinesias. PMID: 9674803 [PubMed - indexed for MEDLINE] Remember a couple of things about dextromethorphan- 1- Less is more. Take the least dose that gives you the effect as a little more will reverse the effect. 2- When you do your research, be aware that dextromethorphan gives the Drug Warriors apoplexy because it is so readily available and has so few side effects. So they put out a lot of lies about it. BTW, it is now 4:41 PM and my dk is down by a third. :) |
Mucuna pruriens for dyskinesia
Some recent work
1. Nat Prod Res. 2010 Jul 13:1-8. [Epub ahead of print] Mucuna pruriens attenuates haloperidol-induced orofacial dyskinesia in rats. Pathan AA, Mohan M, Kasture AS, Kasture SB. Department of Pharmacology, MGV's Pharmacy College, Panchavati, Nashik, Maharashtra, India. Neuroleptic-induced tardive dyskinesia (TD) is a motor disorder of the orofacial region resulting from chronic neuroleptic treatment. The agents improving dopaminergic transmission improve TD. Mucuna pruriens seed contains levodopa and amino acids. The effect of methanolic extract of M. pruriens seeds (MEMP) was studied on haloperidol-induced TD, alongside the changes in lipid peroxidation, reduced glutathione, superoxide dismutase (SOD) and catalase levels. The effect of MEMP was also evaluated in terms of the generation of hydroxyl and 1,1-diphenyl,2-picrylhydrazyl (DPPH) radical. MEMP (100 and 200 mg kg(-1)) inhibited haloperidol-induced vacuous chewing movements, orofacial bursts and biochemical changes. MEMP also inhibited hydroxyl radical generation and DPPH. The results of the present study suggest that MEMP by virtue of its free radical scavenging activity prevents neuroleptic-induced TD. PMID: 20635303 [PubMed - as supplied by publisher] |
Creatine and dyskinesia
Creatine is the "Poor Man's CoQ10 and is in trials somewhere. It is widely used in the sports world-
1. Behav Brain Res. 2009 Jan 30;197(1):90-6. Epub 2008 Aug 12. Oral creatine supplementation attenuates L-DOPA-induced dyskinesia in 6-hydroxydopamine-lesioned rats. Valastro B, Dekundy A, Danysz W, Quack G. Preclinical Research and Development, In Vitro Screening, Merz Pharmaceuticals GmbH, Altenhöferallee 3, 60438 Frankfurt am Main, Germany. L-DOPA-induced dyskinesia (LID) is among the motor complications that arise in Parkinson patients after a prolonged treatment with levodopa (L-DOPA). Since previous transcriptome and proteomic studies performed in the rat model of LID suggested important changes in striatal energy-related components, we hypothesize that oral creatine supplementation could prevent or attenuate the occurrence of LID. In this study, 6-hydroxydopamine-lesioned rats received a 2% creatine-supplemented diet for 1 month prior to L-DOPA therapy. During the 21 days of L-DOPA treatment, significant reductions in abnormal involuntary movements (AIMs) have been observed in the creatine-supplemented group, without any worsening of parkinsonism. In situ hybridization histochemistry and immunohistochemistry analysis of the striatum also showed a reduction in the levels of prodynorphin mRNA and FosB/DeltaFosB-immunopositive cells in creatine-supplemented diet group, an effect that was dependant on the development of AIMs. Further investigation of the bioenergetics' status of the denervated striatum revealed significant changes in the levels of creatine both after L-DOPA alone and with the supplemented diet. In conclusion, we demonstrated that combining L-DOPA therapy with a diet enriched in creatine could attenuate LID, which may represent a new way to control the motor complications associated with L-DOPA therapy.

Vitamin B6
1. J Clin Psychiatry. 2007 Nov;68(11):1648-54.
Vitamin B6 treatment for tardive dyskinesia: a randomized, double-blind, placebo-controlled, crossover study. Lerner V, Miodownik C, Kaptsan A, Bersudsky Y, Libov I, Sela BA, Witztum E. Division of Psychiatry, Ministry of Health Be'er Sheva Mental Health Center, Faculty of Health Sciences, Ben-Gurion University of the Negev, Be'er-Sheva, Israel. lernervld@yahoo.com BACKGROUND: Tardive dyskinesia (TD) is a significant clinical problem. Vitamin B(6) is a potent antioxidant and takes part in almost all of the possible mechanisms that are suggested as being associated with appearance of TD. The aims of this study were (1) to reexamine the efficacy and safety of higher doses of vitamin B(6) versus placebo in a greater sample of patients for a longer time and (2) to evaluate the carryover effect of vitamin B(6). METHOD: A 26-week, double-blind, placebo-controlled trial was conducted in a university-based research clinic from August 2002 to January 2005 on 50 inpatients with DSM-IV diagnoses of schizophrenia or schizoaffective disorder and TD. In a double-blind crossover paradigm, all study subjects were randomly assigned to start treatment with either vitamin B(6) (daily dose of 1200 mg) or placebo. After 12 weeks of treatment and then a 2-week washout, subjects were crossed over to receive the other treatment for 12 weeks. The primary outcome measure was the change from baseline in Extra-pyramidal Symptom Rating Scale (ESRS) scores. RESULTS: The mean decrease in ESRS clinical global impression scores from baseline to endpoint was 2.4 points in patients treated with vitamin B(6) and 0.2 points in patients treated with placebo (p < .0001). The mean decrease in the parkinsonism subscale score was 18.5 points and 1.4 points, respectively (p < .00001), and the mean decrease in the dyskinesia subscale score was 5.2 points and -0.8 points, respectively (p < .0001). CONCLUSION: Vitamin B(6) appears to be effective in reducing symptoms of TD. The specific mechanisms by which vitamin B(6) attenuates symptoms of TD are not clear.

Quercetin
1. Neuropharmacology. 2003 Jun;44(8):1100-6.
Quercetin, a bioflavonoid, attenuates haloperidol-induced orofacial dyskinesia. Naidu PS, Singh A, Kulkarni SK. Pharmacology Division, University Institute of Pharmaceutical Sciences, Panjab University, -160014, Chandigarh, India. Chronic treatment with neuroleptics leads to the development of abnormal orofacial movements described as vacuous chewing movements (VCMs) in rats. Vacuous chewing movements in rodents are widely accepted as one of the animal models of tardive dyskinesia. Oxidative stress and the products of lipid peroxidation are implicated in the pathophysiology of various neurological disorders including tardive dyskinesia. In the present study chronic haloperidol (1.0 mg kg(-1) for 21 days) treatment induced vacuous chewing movements and tongue protrusions in rats. Co-administration of quercetin, a bioflavonoid, dose dependently (25-100 mg kg(-1)) reduced haloperidol-induced vacuous chewing movements and tongue protrusions. Biochemical analysis revealed that chronic haloperidol treatment induces lipid peroxidation and decreases the glutathione (GSH) levels in the forebrains of rats. The antioxidant defense enzymes, superoxide dismutase (SOD) and catalase were also decreased due to chronic haloperidol treatment. Co-administration of quercetin (25-100 mg kg(-1)) significantly reduced the lipid peroxidation and restored the decreased glutathione levels in these animals. Further quercetin (50-100 mg kg(-1)) also reversed the haloperidol-induced decrease in forebrain SOD and catalase levels in rats. The major findings of the present study suggested that oxidative stress plays a significant role in neuroleptic-induced orofacial dyskinesia and quercetin co-administration reverses these behavioral and biochemical changes. Quercetin, a naturally occurring bioflavonoid could prove to be a useful agent in neuroleptic-induced orofacial dyskinesia. PMID: 12763102 [PubMed - indexed for MEDLINE] |
Melatonin
1. Arch Gen Psychiatry. 2001 Nov;58(11):1049-52.
Melatonin treatment for tardive dyskinesia: a double-blind, placebo-controlled, crossover study. Shamir E, Barak Y, Shalman I, Laudon M, Zisapel N, Tarrasch R, Elizur A, Weizman R. Abarbanel Mental Health Center, 15 KKL St, Bat-Yam 59100, Israel. drshamir@hotmail.com Comment in: Arch Gen Psychiatry. 2001 Nov;58(11):1054-5. BACKGROUND: Antipsychotics remain the mainstay of drug intervention in the management of schizophrenia. However, long-term treatment with antipsychotics is associated with a variety of movement disorders, the most disabling of which is tardive dyskinesia (TD), which occurs in up to 50% of patients hospitalized with chronic schizophrenia. The pathophysiology of TD is still unclear and no definite treatment exists. Both dopamine receptor supersensitivity and oxidative stress-induced neurotoxicity in the nigrostriatal system are apparently implicated. The pineal hormone melatonin is a potent antioxidant and attenuates dopaminergic activity in the striatum and dopamine release from the hypothalamus. Thus, it may have a beneficial effect for both the treatment and prevention of TD. METHODS: Using a double-blind, placebo-controlled, crossover study, we evaluated the efficacy of 10 mg/d of melatonin for 6 weeks in 22 patients with schizophrenia and TD. The primary outcome measure was the change from baseline in Abnormal Involuntary Movement Scale (AIMS) score. RESULTS: The decrease (mean +/- SD) in AIMS score was 2.45 +/- 1.92 for the melatonin and 0.77 +/- 1.11 for the placebo treatment groups (P<.001). No adverse events or side effects were noted. CONCLUSION: This is the first clinical evidence for efficacy of melatonin in the treatment of TD. PMID: 11695951 [PubMed - indexed for MEDLINE] |

Dyskinesia,
Rick,
I take my hat off to you, that is an incredible amount of work. These days, I just never seem to have the time. However I am still doing a lot of work for Kings College Hospital London, literature searches, fundraising etc. Looking at the prescription drugs for dyskinesia, amantadine is effective , but looses its effectiveness after around 6 months of use. It is an antiviral drug, and a very similar drug is Rimantadine, with a similar structure. Yesterday, I went to a Christening, and took half a 50mg Stavelo (25mg L-dopa) at 12-30pm. I writhed with dyskinesia until nearly 4-00pm. I can't take less than 25mg L-dopa!! Some time ago, there was no way 50mg would switch me on. It must mean my threshold level of sensitivity to L-dopa has reduced. Is it caused by prolonged use of curcumin, (it repairs BBB), and will I eventually not need L-dopa? Ron |
Ron,
Just a thought, have you changed the way your l-dopa is delivered? Lindy |
Quote:
I had tried Stavelo before, but did not like the lack of control over the amount of entacapone I was getting. If I rememer correctly, entacapone has a reputation for increasing dyskinesia I fly to Scotland for a week, at the end of next week, so I won't be able to keep posting. Ron |
Dyskinesia is my biggest problem. When my meds kick in, I'm dyskinetic ALL THE TIME. Doesn't matter if I cut the pill in half or not. It just wears off sooner.

Hypnosis
Strictly from my own experience this morning. No research on it in so far as I can tell. Which is odd since the French neuro Charcot was big on it and also named PD.
Anyway, I seemed to banish a moderate case of dk this morning with a very simple image involving a thermostat ("Turn it down, Luke." :D ) and it seems to have done the trick. I'm going to work on this one some more. If anyone else wants to try it let me know and I'll post the text I used. You can simply read it into your computer and voila! |
Ron,
As any form of entacapone will increase the available amount of l-dopa to the brain it may be the culprit. I think it is interesting though that some people do less well on stalevo only, and some do less well on entacapone + ldopa, EVEN at the same dose........... so it may be your culprit..... I declined to go on stalevo because I wouldn't be able to control my intake the way I want to. Good luck finding a balance....... and enjoy your holiday. Lindy |
Rick,
I'll give it a go if you don't mind posting it. |
'Atta' Girl...
Self Hypnosis 101
First of all, ditch all preconceptions. It is not what you've seen on television. It is simply you using a script to help your mind to focus. No one else is involved and there are no tricks. You can do this one of two ways- either with a recorder or with your computer. I prefer the latter because it is easy to edit and can be used to generate "modules" that can be combined in moments to deal with something that just came up. The downside is that you have to learn the software. I use a free program called "Audacity" but I think there is one that comes with Windows, too. A voice recorder is much simpler but only if you rehearse a little and correct mistakes as you go. Safety- Use it in the safety of your home and you have nothing to worry about. Do I have to say it? DON'T DO THIS AND DRIVE! Sheesh... If you forget to tell yourself to wake up, you will anyway. it just might be the next morning. There are three modules- the induction, the suggestion, and the awakening. The induction is when the guy in the bad movie says "Look into my eyez!" You will do it a bit different. It is not so much what you say but how you say it. You should try for a soothing monotone. Imagine that you are trying to calm your dog during a thunderstorm. Now record the following- "Let yourself relax as you slip into hypnosis. Listening to my voice. Ignoring all other sounds. Breathing slowly. Easily. Your body growing heavier as you relax more and more. Be aware of the weight of your body as you relax more and more. Breathing slowly. Easily. Growing heavier and more and more relaxed. Ignoring all other sounds but my voice. Calmer and calmer. Now, as I count, feel yourself sinking gently down into hypnosis. More and more relaxed. Heavier and heavier. Five. Four. Three. Two. One. Zero. Sleep. Relaxing more and more. Your body growing heavier. Your mind growing calmer. Five. Four. Three. Two. One. Zero. Sleep." When you are counting, allow about one normal breath for each number. Remember that you are calming your pet. That part above should be about two to two and a half minutes but don't stress about it. Now, record it again. And if needed, a third time. You want about five minutes of this. When finished, you have your induction. I'm not sure what limits are on length of post so will adjourn to the next post. |
Continue to record the following-
"Your dyskinesias result from the sensitivity you have to your medications. You are able to influence that sensitivity and your dyskinesias. I am going to give you an image to use as a tool to do this anytime you wish. It will not be necessary that you enter hypnosis to usethis image, only that you close your eyes and take two slow breaths to begin. This approach will get more and more effective each time you use it, allowing you great control over your sensitivity and the dyskinesia. Now, imagine that you are standing facing a wall at arm's length in front of you. On that wall and at eye level is an old fashioned, round thermostat. Picture your hand reaching out and turning the control counter-clockwise to reduce your dyskinesias. <repeat that last paragraph a total of three times> This approach will get more and more effective each time you use it, allowing you great control over your sensitivity and the dyskinesia." Finally, record this to awken- "Now, you may awaken by silently counting from one to ten, becoming more alert with each count and fully awake at th count of ten." |
Will give this a try. Thank you so much!

some hypno-tips
In general, the more intelligent and imaginative you are the more readily hypnotizeable you are. Add in the well known placebo response and we have a potential major tool here. Keep in mind that you haven't heard of it from your doc not because science has found it lacking but, rather, that the studies have not been done.
Symptom relief is an obvious avenue, but it could be more as well. An example- my wife has fought depression all her life. Twenty years or so ago, as she struggled with Churchill's "black dog", I hypnotized her and simply instructed her to rebalance her brain chemistry and banish the depression. It worked. Also, the thing that led me into the subject were terrible monthly cramping that she had endured for years. Using an image similar to the one used here, the cramping was eliminated with a single session! The power of suggestion is just that - suggestion. We don't necessarily have to know the details. This wonderous melon-sized lump of jelly holds miracles we cannot imagine. Who is to say that the proper approach will not increase levels of GDNF where needed or reduce inflammation? This part of us is an idiot savant and is capable of great things but only if asked. In trying this, it is best done by day and while sitting quietly. Falling asleep is counter productive. Turn offthe phone. Put out the cat. etc. While you may be surprised, don't expect results right away. Go through it ten times before making any judgements. Don't do it more than once a day and take every fourth day off. You are persuading, not coercing. An added advantage- record one without the middle part.You can get profoundly relaxed without suggesting anything. It soothes those weary muscles quite well. I hope that some of you will get interested in this. It has been neglected for a century and it is a great patient empowerment tool. |
Nicotine
I figure once I pass 60 I willbe entitled to smoke, drink, and chase women. I figure that I will be shuffling after my wife demanding to know where she hid my pipe and wine. :)
1. Biochem Pharmacol. 2009 Oct 1;78(7):677-85. Epub 2009 May 9. Multiple roles for nicotine in Parkinson's disease. Quik M, Huang LZ, Parameswaran N, Bordia T, Campos C, Perez XA. The Parkinson's Institute, Sunnyvale, CA 94085, United States. mquik@parkinsonsinstitute.org There exists a remarkable diversity of neurotransmitter compounds in the striatum, a pivotal brain region in the pathology of Parkinson's disease, a movement disorder characterized by rigidity, tremor and bradykinesia. The striatal dopaminergic system, which is particularly vulnerable to neurodegeneration in this disorder, appears to be the major contributor to these motor problems. However, numerous other neurotransmitter systems in the striatum most likely also play a significant role, including the nicotinic cholinergic system. Indeed, there is an extensive anatomical overlap between dopaminergic and cholinergic neurons, and acetylcholine is well known to modulate striatal dopamine release both in vitro and in vivo. Nicotine, a drug that stimulates nicotinic acetylcholine receptors (nAChRs), influences several functions relevant to Parkinson's disease. Extensive studies in parkinsonian animals show that nicotine protects against nigrostriatal damage, findings that may explain the well-established decline in Parkinson's disease incidence with tobacco use. In addition, recent work shows that nicotine reduces l-dopa-induced abnormal involuntary movements, a debilitating complication of l-dopa therapy for Parkinson's disease. These combined observations suggest that nAChR stimulation may represent a useful treatment strategy for Parkinson's disease for neuroprotection and symptomatic treatment. Importantly, only selective nAChR subtypes are present in the striatum including the alpha4beta2*, alpha6beta2* and alpha7 nAChR populations. Treatment with nAChR ligands directed to these subtypes may thus yield optimal therapeutic benefit for Parkinson's disease, with a minimum of adverse side effects.
