Any one using anticholinergics which was once used as only medicine for PD?
http://www.ask.com/bar?q=anticholine...holinergic.htm Parkinson’s disease (paralysis agitans) is a neurological disorder which principally strikes individuals of middle age and older. In the general population, Parkinson's disease affects approximately 1 in 1000 people (1). It has been estimated that in persons aged 65 years and older, the incidence is approximately 1% (2). From a biochemical perspective, Parkinson's is thought to be caused by degeneration of dopaminergic neurons in the neostriatum, a region of the basal ganglia in the brain important in the regulation of neural impulses which control motor functions (3-5). Although the primary agents used for the pharmacological treatment of Parkinson’s disease are those which directly or indirectly act as dopamine agonists, the first drugs used in its treatment were those with anticholinergic activity (4). It was not until the late 1960’s that the use of levodopa (L-dopa) for the treatment of Parkinson’s disease was established. Although L-dopa has proved to be a monumental advance in the treatment of Parkinson’s disease, by itself it is not curative nor sufficient to completely alleviate the symptoms of the disease, which typically include an involuntary resting tremor, muscular weakness, bradykinesia, and muscular rigidity (5). Further, the usefulness of dopamine is limited by a “wearing-off” phenomenon which appears with prolonged usage (3-5). Although much attention has been directed by researchers and the pharmaceutical industry towards the understanding and development of pharmacological agents which modulate dopaminergic pathways, relatively little effort has been placed towards understanding the pharmacokinetics of those drugs which act at the level of the cholinergic system (1). The anticholinergic drugs used in the treatment of Parkinson's disease (ACP), despite their adjunct role, are nevertheless important agents as they provide an alternate mechanism of action which may alleviate some of the troublesome symptoms of the disease, in particular the involuntary resting tremor. They are used as monotherapy early in the course of the disease, and act synergistically with L-dopa in more advanced stages (3-5). Because ACP are used early in the disease progression, they are potentially helpful in delaying the need for L-dopa treatment. This may allow the patient to derive optimal use of L-dopa later in the course of the disease. In addition, they may allow for a reduction in the dose of L-dopa required in more advanced cases, thus further extending the use of L-dopa (6). The ACP are clinically useful in another respect, as they can diminish the extrapyramidal side effects associated with the use of antipsychotic agents.The purpose of this article is to outline similarities and differences between the ACP, and to highlight deficiencies in the current state of pharmacokinetic knowledge.

I posted about this before but just a reminder, there are articles out there that link cognitive changes with anticholinergics. When the drug is stopped, the dementia/memory problems go away (this is not to say that if you have dementia already, it will be negated if you start taking these drugs and then stop them) so do the research before taking these.

I took this drug in the beginning before l-dopa. it really helped the rigidity, but i was not in the real world; it was like an invisible wall was there between me and the world and I was still teaching.
However, now that i see it is being used for advanced; i must say that i do recall relief and relaxing of my symptoms and i may inquire at my neuro's about its' use now. i didn't want to give it up - had to. paula

Let me preface this by stating what we all know about PD "meds"...everyone responds/reacts differently so that what I am about to say should be taken in that context. For my pwp, Cogentin was a "nightmare" medication in that she became so cognitively impaired that it caused her to be removed from her position as the medical assistant to a cancer ENT physician for whom she had worked for 22 years. The sad thing about this was that the drug worked remarkably well to alleviate (actually, eliminate) her tremors...actually, had no tremor while taking Cogentin. Doreen actually took on another personality to the point where I did not recognize her as the same person I had known for over 30 years. It was only through my research of this medication that I realized what was happening to her. I contacted her neurologist and he immediately took her off Cogentin. This had to have been the worst period of time since she had been dx'd with PD...and, to this day, Doreen has no recollection of what happened to her while taking Cogentin. As I said...the medication absolutely stopped the tremor so that for someone else, it could very well be an ideal "med" that would not cause the cognitive impairment experienced by Doreen. I merely thought that I would post our experience as a warning to anyone who might be taking Cogentin...or considering taking it...to make you aware of any POSSIBILITY of such a terrible adverse reaction. For those of you who might be taking it..considering taking it..I hope you'll have the good results that this "med" can provide without the horrendous cognitive side effects.

Hi, I take artane (trihexyphenydyl) along with baclofen for my symptoms. I take as little artane as possible, only 2 mg a day, because it affects short term memory. The balance between dopamine and acetylcholine is important. If too much acetylcholine, symptoms arise. Artane dampens down the acetylcholine. The main Alzheimer's drug does just the opposite, so you can see that acetylcholine is important for memory.

My neuropsychiatrist is very particular about anticholinergics, as I am stiffness-dominant and at greater risk for dementia than tremor-dominant PWP. If I have a cold I can take Benedryl, but must get off it ASAP. At night I can take ibuprofen (Motrin) for sleep but not Tylenol PM, because it contains Benedryl. If I liked nursing homes, I suppose anticholinergics would be great stuff.

I am about to embark on a program of taking hyoscyamus niger in an attempt to alleviate the tremors associated with Parkinson's disease. The hyoscyamus niger is sourced from the botanical henbane, from Jade mountain medicine in Ashland, Oregon. The problem with ACP is that titrating in is a tricky process. One has to get the dose just right to reduce tremors without expressing some of the rather nasty side effects. Wish me luck.
