Types Of Parkinson’s Medication
There is currently no cure for Parkinsons, but medication can usually provide good symptom control for a long time. Meanwhile researchers continue to search for a cure, and research into new and improved medicines continues.
Dopamine is a chemical messenger made in the brain. The symptoms of Parkinsons are largely associated with a decrease in the levels of this chemical, due to the death of the nerve cells that make it.
Unfortunately, taking dopamine as a drug treatment would not help you, because it cannot cross into your brain where it is needed. There are a number of approaches that can be taken to try to compensate for the dopamine deficit and therefore alleviate the symptoms of the condition. Ultimately these will increase the levels of dopamine and help to overcome some of the symptoms of the condition. However, many of the medications may have side effects which should be taken into account when being prescribed.
A wide range of Parkinsons medications is available. These may be taken in many different forms. Your doctor will try to find the medication that is most suitable for you throughout your Parkinsons treatment. What is available will also depend on the country in which you live.
Your Parkinson’s Drug Treatment
Dopamine is a chemical messenger made in the brain. The symptoms of Parkinsons appear when dopamine levels become too low. This is because many of the cells in your brain that produce dopamine have died or are dying. Taking dopamine as a drug doesnt work because it cannot cross the blood brain barrier. To get around this, doctors use other medication that can act in a similar way.
What Drugs Can Cause Parkinsons Disease
Physiologically, Parkinsons disease is caused due to low levels of dopamine secretion in the body. Thus, any medication that blocks the level of dopamine in the body and cause Parkinsons symptoms. Dopamine is a brain chemical that essentially helps control movement of a person. The various drugs include-
Antipsychotic Drugs- Parkinson symptoms are seen to be common in patients who are prescribed antipsychotic drugs. Parkinsonism as a side effect of chlorpromazine is quite common. Typical antipsychotic drugs include chlorpromazine, promazine, haloperidol, perphenazine, fluphenazine and pimozide. Dopamine receptors are widely distributed in the brain and typical antipsychotics may affect dopamine receptors in the striatum.
GI Motility Drugs- GI prokinetic drugs like metoclopramide, levosulpiride, clebopride, itopride and domperdone may cause side effects thereby making the patient prone to Parkinsonism.

Parkinsons Disease Medications: The Facts
There have been many developments in Parkinson’s disease treatments in recent years. As such, doctors now have a greater understanding of traditional Parkinson’s disease medications and their side-effects. Scientists have also developed new drugs to help control tremors, slowed movement and other Parkinson’s symptoms.
Before we explore the best medication for Parkinson’s disease, it’s important to address the facts. Firstly, Parkinson’s disease medications cannot cure your condition, nor will they slow down the progression of your symptoms. These medications are prescribed to help patients live independently and improve their quality of life.
It’s important to note that some patients do not respond well to Parkinson’s disease medications. In this case, there are plenty of other treatment options to consider such as homeopathic remedies, physical therapy and surgical intervention. Again, none of these treatments provides a cure, but they can help ease or control your symptoms.
Treatment Of Neurobehavioral Features
Treatment of cognitive deficits associated with PD is as challenging as the treatment of Alzheimers disease and other dementias. While the general assumption has been that cognitive deficits are a feature of late-stage PD, clinically inapparent cognitive changes on neuropsychiatric testing may be found . With the introduction of cholinesterase inhibitors such as donepezil , rivastigmine , and galantamine and the NDMA antagonist memantine , it is possible that cognition, orientation and language function will improve, and that such improvement will lead to a meaningful improvement in function. Both donepezil and rivastigmine improve cognition to the same effect, but donepezil is better tolerated . The largest and best-designed study of rivastigmine in dementia associated with PD involved 541 patients enrolled in a 24-week randomized, multicenter, double-blind clinical trial . The patients had a relatively mild dementia , with onset of dementia about 2 years after onset of PD symptoms. The mean ADAS-cog score, the primary efficacy variable, improved by 2.1 points in the rivastigmine group, compared to 0.7 in the placebo group , and the MMSE improved by 0.8 in the rivastigmine group and worsened by 0.2 in the placebo group . At the end of the study, 55.5% were receiving 9 to 12 mg. The adverse effects that were significantly more frequent in the rivastigmine group were nausea, vomiting, dizziness, and tremor.

Dementia With Lewy Bodies
- Dementia with Lewy bodies is a progressive, neurodegenerative disorder in which abnormal deposits of a protein called alpha-synuclein build up in multiple areas of the brain.
- Dementia with Lewy bodies is second to Alzheimers as the most common cause of degenerative dementia that first causes progressive problems with memory and fluctuations in thinking, as well as hallucinations. These symptoms are joined later in the course of the disease by parkinsonism with slowness, stiffness and other symptoms similar to PD.
- While the same abnormal protein is found in the brains of those with PD, when individuals with PD develop memory and thinking problems it tends to occur later in the course of the disease.
- There are no specific treatments for DLB. Treatment focuses on symptoms.
Botulinum Toxin & Collagen Injections Treat Muscle Spasms Voice & Speech Impairments
Botulinum toxin is a medication used to treat painful muscle spasms associated with movement disorders. Froedtert & the Medical College of Wisconsin is highly experienced with this procedure and performs the most in the region. The approach uses neurotoxins, injected in small amounts, to disrupt the flow of nerve impulses to excessively contracted or spastic muscles, reducing movements for a period of weeks or months.
Two forms of botulinum toxinBTn-A and BTn-B are approved by the Food and Drug Administration for use in selected medical conditions.
Collagen injections are used to treat voice and/or speech impairment for patients with Parkinsons disease.

There have been rapid and remarkable changes over the past decade in treating Parkinsons disease . The development of new medicines and the understanding of how best to use them and the older drugs have significantly improved the quality of life for people with the disease.
There is currently no treatment that has been proven to affect the disease progression or development of medication that can slow the disease process. There are two general approaches to the treatment of PD improve the symptoms with medications and engage in physical therapy. Most patients with PD can be adequately treated with medicines that alleviate their symptoms. For the approximately 15% of patients for whom medicines are not sufficiently effective, new, highly effective, and safe surgical treatments are available.
Choices about medicines made early in the course of the disease have a strong impact on the long-term course of the illness. Therefore, you should seek the advice of doctors specially trained in treating PD even when the illness is only suspected. Movement disorders specialists are neurologists who have completed their training in neurology and have received special advanced training in treating PD and other related diseases.

A Critical Reappraisal Of The Worst Drugs In Parkinsons Disease
What are the worst drugs for Parkinsons disease patients? Couldnt a simple list be assembled and disseminated to the Parkinson community? Recently Ed Steinmetz, an experienced neurologist in Ft. Meyers, FL pointed out to me, a list approach published in the Public Citizen Newsletter . The approach was to list every drug associated with a single confirmed or unconfirmed symptom of Parkinsons disease or parkinsonism. Parkinsons disease is defined as a neurodegenerative syndrome , whereas parkinsonism encompasses a wider net of drug induced and other potential causes. In parkinsonism symptoms are similar to Parkinsons disease, but patients do not have Parkinsons disease. Patients and family members confronted with a simple drug list approach may falsely conclude that most medicines are bad for Parkinsons disease, and that any medicine may cause parkinsonism. This concept is in general, incorrect. Although the approach is well-meaning, it is in need of a major revision, as Parkinsons disease and parkinsonism are too complex to summarize by simple lists. In this months column I will try to summarize the key information that patients and family members need to know about the worst pills, for Parkinsons disease and parkinsonism.

Medication Names And Forms
Most medications have two names. The generic name describes the active ingredient in the drug. Every drug that has the same active ingredient will have the same generic name, no matter who manufactures it. The different drug companies who produce the medication market it using a brand or trade name and these may vary from country to country.
For example, the levodopa group of drugs can exist in a number of forms. Each of these contains the chemical levodopa in combination with a second chemical called carbidopa. Together, these are referred to as co-careldopa.
Not all medications are available in each of the European countries, and they may have different brand names. You can obtain further details from your national regulatory authority. Contact details can be obtained from the European Medicines Agency website.

Levodopa: The Most Effective Drug For Treating Parkinsons
Levodopa, also known as L-DOPA, has long been, and continues to be, the most effective drug in treating Parkinsons disease symptoms. Most people with Parkinsons disease will take this drug at some point. There are side effects that can occur with Levodopa including nausea, fatigue and orthostatic hypotension. Often these side effects can be successfully treated so that Levodopa can be tolerated better. In addition, as the disease progresses and the brain has less ability to produce and process dopamine, dyskinesias, or involuntary movements can develop from Levodopa.

Michael J. Fox and people from his foundation answer questions about Parkinsons in a Google Hangout
Interestingly, Daniel Weintraub, MD, associate professor of psychiatry and Neurology at the Perelman School of Medicine at the University of Pennsylvania, says that ICDs are most likely to manifest in men as gambling and hyper sexuality, whereas in women it expresses as shopping and overeating.
Needless to say, these compulsive behaviors can have serious repercussions.
Ive seen marriages break up and lives ruined as a result of dopamine agonists, says Howard Weiss, director of the Parkinsons Disease and Movement Disorder Programs at the LifeBridge Health Brain & Spine Institute in Baltimore. Ive had at least three patients who have lost their homes because of bankruptcy after taking the drugs. It sounds like a joke, but its not.
Whats more, ICDs are shockingly common. Weintraub cites a study that demonstrated about 14% of people with PD experience 1of 4 of the typical ICD behaviors. He says his own guess is more like 17% to 20%, perhaps even 25%.
The reason that ICD might be even more prevalent than statistics show lies in the fact that they can easily slip under a doctors radar. Many patients arent forthcoming about the symptoms, and doctors may not take the time to ask the right questions.
Most doctors have no idea how to diagnose ICDs, says Weiss, and most patients are in the dark.
