What Drugs Can Cause Parkinson’s Disease

Myth : Deep Brain Stimulation Is Experimental Therapy

What are the causes of Parkinson’s disease? Are there disorders that have similar symptoms?

Fact: Deep brain stimulation, or DBS, is a procedure in which doctors place electrodes in the brain at the point when medications are less effective in masking motor symptoms, such as tremor, stiffness and slowness of movement.

While it may sound frightening and futuristic, its been around and successfully used for decades. DBS works very similarly to a pacemaker, except the wire is in the brain, not in the heart. Its been a standard procedure for the past two decades.

What Treatments Are Available For Parkinsons Psychosis

Your doctor may first reduce or change the PD medication youre taking to see whether that reduces psychosis symptoms. This is about finding a balance.

People with PD may need higher doses of dopamine medication to help manage motor symptoms. But dopamine activity shouldnt be increased so much that it results in hallucinations and delusions. Your doctor will work with you to find that balance.

Which Test Can Be Done When The Diagnosis Is In Doubt

I request a small set of tests on almost all patients I diagnose with Parkinsons. These detect some mimics of Parkinsons disease.

Some doctors dont request all these tests. And for a good reason.

The diagnosis of Parkinsons mimics is primarily based on a careful history and examination.; Even in my practice, these tests change the diagnosis only in a minority of patients.

I like the additional confirmation provided by these tests. They also have other benefits. For example, they help me determine the proper dosages of medications like Amantadine.

Simple tests to detect Parkinsons Mimics
1. MRI-Brain with size measurements of brain parts called the midbrain and pons. I usually also request a unique picture called SWI, which shows iron inside the brain.

2. Blood tests:

  • Ceruloplasmin level & eye examination to look for a ring of copper
  • Ferritin level

    What Medications Are Used To Treat Parkinsons Disease

    Medications are the main treatment method for patients with Parkinsons disease. Your doctor will work closely with you to develop a treatment plan best suited for you based on the severity of your disease at the time of diagnosis, side effects of the drug class and success or failure of symptom control of the medications you try.

    Medications combat Parkinsons disease by:

    • Helping nerve cells in the brain make dopamine.
    • Mimicking the effects of dopamine in the brain.
    • Blocking an enzyme that breaks down dopamine in the brain.
    • Reducing some specific symptoms of Parkinsons disease.

    Levodopa: Levodopa is a main treatment for the slowness of movement, tremor, and stiffness symptoms of Parkinsons disease. Nerve cells use levodopa to make dopamine, which replenishes the low amount found in the brain of persons with Parkinsons disease. Levodopa is usually taken with carbidopa to allow more levodopa to reach the brain and to prevent or reduce the nausea and vomiting, low blood pressure and other side effects of levodopa. Sinemet® is available in an immediate release formula and a long-acting, controlled release formula. Rytary® is a newer version of levodopa/carbidopa that is a longer-acting capsule. The newest addition is Inbrija®, which is inhaled levodopa. It is used by people already taking regular carbidopa/levodopa for when they have off episodes .

    Common Drugs For Parkinson’s Disease

    Levodopa and carbidopa . Levodopa is the most commonly prescribed medicine for Parkinsonâs. Itâs also the best at controlling the symptoms of the condition, particularly slow movements and stiff, rigid body parts.

    Levodopa works when your brain cells change it into dopamine. Thatâs a chemical the brain uses to send signals that help you move your body. People with Parkinsonâs donât have enough dopamine in their brains to control their movements.

    Sinemet is a mix of levodopa and another drug called carbidopa. Carbidopa makes the levodopa work better, so you can take less of it. That prevents many common side effects of levodopa, such as nausea, vomiting, and irregular heart rhythms.

    Sinemet has the fewest short-term side effects, compared with other Parkinsonâs medications. But it does raise your odds for some long-term problems, such as involuntary movements. An inhalable powder form of levodopa and the tablet istradefylline have been approved for those experiencing OFF periods, OFF periods can happen when Parkinsonâs symptoms return during periods between scheduled doses of levodopa/carbidopa.

    People who take levodopa for 3-5 years may eventually have restlessness, confusion, or unusual movements within a few hours of taking the medicine. Changes in the amount or timing of your dose will usually prevent these side effects.

    Dopamine agonists. These drugs act like dopamine in the brain. They include pramipexole , rotigotine , and ropinirole , .

    Medication Guidelines For Parkinson’s Disease

    There is no one best mix of Parkinsonâs medicines. You and your doctor will have to try a few treatment approaches to figure out the best one for you.

    But there are some general guidelines for taking your medication. Be sure to ask your doctor or pharmacist for any specific tips for your treatment.

    Delayed Administration And Contraindicated Drugs Place Hospitalized Parkinsons Disease Patients At Risk

    Problem: One-third of all patients with Parkinsons disease visit an emergency department or hospital each year, making it a surprisingly common occurrence.1 The disease affects about 1 million people and is currently the fourteenth leading cause of death in the US. Hospitalization can be risky for patients with Parkinsons disease when viewed from the perspective of pharmacological management.

    Patients with Parkinsons disease require strict adherence to an individualized, timed medication regimen of antiparkinsonian agents. Dosing intervals are specific to each individual patient because of the complexity of the disease. It is not unusual for patients being treated with carbidopa/levodopa to require a dose every 1 to 2 hours. When medications are not administered on time, according to the patients unique schedule, patients may experience an immediate increase in symptoms.2,3 Delaying medications by more than 1 hour, for example, can cause patients with Parkinsons disease to experience worsening tremors, increased rigidity, loss of balance, confusion, agitation, and difficulty communicating.2 Studies show that three out of four hospitalized patients with Parkinsons disease do not receive their medications on time, or have had doses entirely omitted.4 According to the National Parkinson Foundation, 70% of neurologists report that their patients do not get the medications they need when hospitalized.2

    Parkinson’s Disease – Causes, Symptoms & Treatment

    Recently, I was doing an interview about Parkinsons troublesome issues and I had to admit that by far my most troublesome and annoying problem is related to the effects of my gut. This is true for the majority of us living with this disease. Whether it be a direct or indirect consequence of our illness is irrelevant in my opinion when the effect is the same. Plus to be honest I am not sure anyone of us can tell the difference most of the time.

    As I have re-discovered the agony of suffering from one of these ailments over the last several months when I had several bouts of ileus. In my opinion,;there is nothing worse than having stomach pain, bloating, nausea, indigestion, and gas to make life miserable.

    Below are all the plausible GI symptoms all of us can experience throughout our journey with PD.1 The most common symptoms are those related to poor motility or dysmotility and can be compounded by the effect of the medication.

    The Nervous System & Dopamine

    To understand Parkinson’s, it is helpful to understand how neurons work and how PD affects the brain .

    Nerve cells, or neurons, are responsible for sending and receiving nerve impulses or messages between the body and the brain. Try to picture electrical wiring in your home. An electrical circuit is made up of numerous wires connected in such a way that when a light switch is turned on, a light bulb will beam. Similarly, a neuron that is excited will transmit its energy to neurons that are next to it.

    Neurons have a cell body with branching arms, called dendrites, which act like antennae and pick up messages. Axons carry messages away from the cell body. Impulses travel from neuron to neuron, from the axon of one cell to the dendrites of another, by crossing over a tiny gap between the two nerve cells called a synapse. Chemical messengers called neurotransmitters allow the electrical impulse to cross the gap.

    Neurons talk to each other in the following manner :

    The Connection Between Pd And Drug

    In addition to potentially causing parkinsonism in the general population, these medications should definitely be avoided in people who have parkinsonism from other causes, such as PD. APDA has created a list of Medications to be Avoided or Used With Caution in Parkinsons Disease. It is important to note that there are anti-psychotics and anti-nausea medications which do;not;cause parkinsonism and can be used safely by people with PD.

    Sometimes, a person without a diagnosis of PD is prescribed a medication which leads to a side effect of drug-induced parkinsonism. The prescribing physician may stop the new medication, but the parkinsonism does not resolve. The patient remains off the medication with continuing symptoms, and eventually is given a diagnosis of PD. In this scenario, that person most likely had dopamine depletion in the brain which had not yet manifested as a clinical symptom. The prescription medication that blocked the dopamine receptor, was the proverbial straw that broke the camels back, inducing the full-fledged symptoms of dopamine depletion and revealing that the person did in fact have PD.

    The differences of PD vs drug-induced parkinsonism

    There are key differences to note between parkinsonism from PD and parkinsonism as a side effect of medication.

    Natural Remedy For Parkinsons #4 Chlorella And Borax:

    Parkinsons Disease

    If you have a neurological disease such as Parkinsons orAlzheimers, the importance of removing heavy metals from the body especiallyfrom the brain and nervous system cannot be overstated. Heavy metalsaccumulate in the brain and nervous system at a rapid rate and cause damage tothe neurological pathways and brain inflammation. Fluoride is one ofthe worst, however, mercury, lead, aluminium and cadmium are also extremely dangerous.Chlorella and borax not only remove these heavy metals completely, theycontinue to prevent further toxic build-ups.

    Chlorella is a miracle blue-green algae and one of themost powerful detoxifiers and chelators yet discovered. Whenits combined with cilantro, its benefits are enhancedsignificantly. A Russian study found that chlorella, combined with cilantro,was able to remove all heavy metals from the body, including fluoride and mercury,with no adverse or harmful side effects. You can purchase chlorellain powdered form online or from most health food stores. Just make sure you buythe Broken Cell Wall Chlorella as this is the strongest and most bio-available.For dosage recommendations, simply follow the directions on the container.

    How To Avoid Dip

    The incidence rate of DIP has proved difficult to assess, due to the prevalence of misdiagnosis as PD. Older people and women are at higher risk of DIP, and genetic factors may also play a role.2

    The only way to develop DIP is by taking a prescription drug that impacts the brains dopamine system. If you dont take those drugs, you cannot develop it.

    Unfortunately, in some cases, DIP is misdiagnosed as PD. Researchers discovered that 6.8% of patients diagnosed with PD were later reclassified as having DIP.3 This mistake is particularly harmful since doctors may prescribe drugs to manage PD symptoms instead of stopping the drug thats causing DIP.

    Discontinuing the responsible drug most often ends DIP. However, in some cases, the symptoms persist. In others, the parkinsonism continues to worsen along a track consistent with PD. Researchers have postulated that in these cases the drugs unmasked PD, which may have otherwise gone unexpressed.

    Synopsis

    If you dont take a prescription drug that causes DIP, then you cannot develop it. People experiencing DIP can usually end it by discontinuing the medication that caused it, but for some people, the symptoms persist or worsen.

    How Is Parkinsons Disease Treated

    There is no cure for Parkinsons disease. However, medications and other treatments can help relieve some of your symptoms. Exercise can help your Parkinsons symptoms significantly. In addition, physical therapy, occupational therapy and speech-language therapy can help with walking and balance problems, eating and swallowing challenges and speech problems. Surgery is an option for some patients.

    What Are The Other Forms Of Medicines That Can Cause Parkinsons Disease

    Some of the other common medicines which can cause Parkinsons disease may include some forms of anti-depressants, anti-nausea drugs, drugs used for the treatment of vertigo, drugs used for epilepsy and anti-arrhythmics. It should be remembered that not all drugs in these classes may cause signs of Parkinsonism. The doctor generally makes the patient aware of the side-effects before prescribing a certain form of drugs. Nevertheless, it is important from the patients part to ask about the side-effects of the prescribed medicines.

    Be Your Own Health Advocate

    Will stopping of offending drug improve Drug Induced Parkinsonism? – Dr. Guruprasad Hosurkar

    Every drug carries risks.The Save Institute recommends avoiding prescriptions drugs except in matters of life and death. The dire, life-altering consequences of DIP are a striking example of why this recommendation is so important for maintaining your health.

    Do your own research about the potential side effects of any drug, and always seek a natural remedy instead of a synthetic drug. In the case of osteoporosis and osteopenia, reversal is possible through a combination of diet, exercise and bone-healthy lifestyle choices.

    What Is The Difference Between Drug Induced Parkinsons Disease And Typically Occurring Parkinsons Disease

    It has been seen that drug-induced Parkinsonism usually occur on both sides of your body while usual Parkinsons starts from one side of the body. Apart from this, the medication-induced signs generally are seen to go away after the medicine is finished. However, it may take few months to stop, but is does stop eventually. On the contrary, the typically occurring Parkinsons disease cannot be reversed. Another thing to be kept in mind is that medication-induced Parkinsons disease is not progressive, unlike the typical Parkinsons disease.

    Antipsychotics To Deal With Psychotic Symptoms

    Psychotic symptoms remain present in approximately half of the patients dealing with Parkinsons disease. These symptoms create detrimental effects on the quality of life lead by patients and their caregivers, while result in mortality in some cases. Pathogenesis associated with psychotic symptoms in Parkinsons disease is complicated and usage of antipsychotics i.e. dopaminergic medications involve many risk factors. Treatment for psychotic symptoms in patients dealing with Parkinsons disease is complicated because of the property of any antipsychotic medicine to make motor symptoms worse.

    Anesthetic Drugs May Interact With Medications Used For Parkinsons Disease

    Lorri A. Lee, MD; Tricia A. Meyer, PharmD, MS, FASHP

    An estimated one million people in the United States have been diagnosed with Parkinsons Disease making it one of the most common neurological disorders in patients. This number is estimated to double in the next 30 years as PD is associated with increasing age. PD patients have a deficiency of dopamine in their brain and many of their medications are used to increase this neurotransmitter. They are frequently very sensitive to missing even one dose of their Parkinson medications and may exhibit increased rigidity, loss of balance, agitation, and confusion if their dosing schedule is delayed. Neuroleptic malignant syndrome or parkinsonism-hyperpyrexia syndrome can develop if their medications are held too long or as a result of serious infection.1 Many drugs used in the perioperative period, such as metoclopramide, butyrophenones , and phenothiazines have anti-dopaminergic activity that can worsen the symptoms of PD.

    PD patients may be prescribed selective MAOI-B medications such as selegiline and rasagiline that inhibit metabolism of dopamine. Though caution is still advised, several studies have demonstrated that the risk of serotonin syndrome with these selective MAOI-B drugs is extremely low, even in combination with serotonergic antidepressants.

    Not All Tremors Are Associated With Parkinsonism

    Contraindicated Drugs in Parkinson Disease Patients

    Other than parkinsonism, some medications can also cause drug-induced tremors, which are not associated with parkinsonism. Drug-induced tremors can take the form of postural or action tremors, and they can accompany other PD-like symptoms. Postural tremors occur when the body part is held against gravity, such as when holding something away from the body. An action tremor occurs when the affected body part is moving. Drug-induced tremors also tend to occur on both sides of the body, whereas tremors associated with PD tend to affect one side more than the other. Although similar to DIP, drug-induced tremors differ in that they are not resting tremors. Resting tremors occur only when a limb is at rest and can affect the fingers, hands, feet, or jaw. Resting tremors are also only associated with PD or DIP.
