Tips For Caring For Someone With Parkinsons Disease

Caring for a loved one with early onset Parkinsons can be difficult. If youre a caregiver for someone with this condition, its important that you remember your own emotional and physical health.

Not only are you dealing with a difficult diagnosis, youre also managing an increased number of responsibilities. Burnout is common in caregivers, so make sure youre checking in with your own needs.

The Michael J. Fox Foundation Center for Parkinsons Research recommends these tips for caregivers:

People Who Already Have Pd: Should I Get Tested And What Do I Do With The Results

Up until recently, even people with PD with a very extensive family history of PD would not necessarily receive genetic testing because there were no clear uses for the results. There has been research directed at figuring out whether PD caused by or associated with certain mutations have particular clinical characteristics . However, there remains so much variability in clinical characteristics even among people with the same PD mutation, that there are still no clear practical implications in knowing whether a PD patient harbors a particular mutation. There is also, so far, no difference in treatment or management of PD whether or not the patient harbors one of the known mutations. That may change however, with the advent of clinical trials that target particular mutations.

There are two genes that have received particular attention recently because medications are being developed that target those with mutations of these genes.

GBAis a gene that increases the risk of developing PD. The gene encodes for the GBA enzyme, a protein used by the body to break down cellular products. Having two abnormal GBA genes causes Gauchers disease, which is characterized by the buildup of these cellular products resulting in fatigue, bone pain, easy bleeding and an enlarged spleen and liver. When a person inherits only one abnormal gene, he or she does not develop Gauchers disease, but does incur a small increased risk of PD. Most people with one mutated GBA gene do not develop PD.

Testing For Parkinsons Disease

There is no lab or imaging test that is recommended or definitive for Parkinsons disease. However, in 2011, the U.S. Food and Drug Administration approved an imaging scan called the DaTscan. This technique allows doctors to see detailed pictures of the brains dopamine system.

A DaTscan involves an injection of a small amount of a radioactive drug and a machine called a single-photon emission computed tomography scanner, similar to an MRI.

The drug binds to dopamine transmitters in the brain, showing where in the brain dopaminergic neurons are.

The results of a DaTscan cant show that you have Parkinsons, but they can help your doctor confirm a diagnosis or rule out a Parkinsons mimic.

Surgery And Deep Brain Stimulation

Parkinsons disease

Deep brain stimulation is a treatment for Parkinsonâs disease that uses an implantable pacemaker-like device to deliver electrical pulses to parts of the brain involved in movement. The DBS system consists of leads precisely inserted into a specific brain target, the neurostimulator implanted in the chest, and extension wires that connect the leads to the neurostimulator. Though implantation of the system requires a neurosurgical procedure, the treatment itself consists of long-term electrical stimulation. Advantages of DBS include its ability to reduce the high doses of medications , its adjustability , and its reversibility DBS was approved by the Food and Drug Administration as a treatment for PD in 2002 and according to Medtronic , more than 80,000 patients have undergone DBS surgery worldwide.

Typical candidates are those who have motor fluctuations or periods of âoffâ time with troublesome symptoms alternating with periods of âonâ time with good symptom control, and also with possible periods of excessive movement .

Not all patients with Parkinsonâs disease are good candidates for treatment with DBS. Approximately 10â20% of patients considered for possible treatment with DBS include those:

What does this task measure?OTS evaluates executive function, spatial planning and working memory based upon the Tower of Hanoi test.What does this task involve?The participant is shown two displays of coloured balls held in stockings suspended from a beam. There is a row of numbered boxes along the bottom of the screen. The participant is asked to solve problems by working out how they would move the balls in the bottom display in order to make them match the arrangements of the ball sin the top display. After some training and practice problems, the participant is asked to work out in their head how many moves the solutions to these problems require, and then touch the appropriate box at the bottom of the screen to indicate their response.Why use this task?Performance on the OTS task by Parkinsons patients is associated with the COMT genotype in the early stages of the disease8. In this sense, the COMT gene is responsible for levels of hormones and communication of neurotransmitters. When the COMT gene is no longer fully functioning, dopamine levels may drop and serotonin may rise. Following this, communication between neurotransmitters can fail. This can lead to an inability to spatially plan as communication within the frontal lobe, responsible for planning, solving and organising, has failed.

Treatment Options For Early Onset Parkinsons Disease

Parkinsons treatment aims to slow the diseases progression. Medication treatment options may include the following:

  • Levodopa is a chemical thats converted to dopamine in the brain. People with early onset Parkinsons may experience more negative side effects, such as involuntary movements.
  • MAO-B inhibitors can help reduce the breakdown of dopamine in the brain.
  • Catechol-O-methyltransferase inhibitors can help extend Levodopas effects on the brain.
  • Anticholinergics can help reduce tremors.
  • Amantadine may be used to improve muscle control and relieve stiffness.

Foster A Good Relationship

Lastly, maintaining your relationship and communication with the person with Parkinsonâs can be the most challenging and rewarding aspect of caregiving. As Parkinsonâs disease progresses, the roles change and the person with Parkinsonâs may go from being an independent head of the household to a very dependent person requiring a significant level of care. However, research shows that despite high levels of strain, caregivers with good quality relationships have reduced depression and better physical health. Remember, as a caregiver your service to your loved one is beyond measure in terms of love, depth of care, and concern.

What Causes Parkinson’s Disease

Approach to the Exam for Parkinson’s Disease

In the very deep parts of the brain, there is a collection of nerve cells that help control movement, known as the basal ganglia . In a person with Parkinson’s disease, these nerve cells are damaged and do not work as well as they should.

These nerve cells make and use a brain chemical called dopamine to send messages to other parts of the brain to coordinate body movements. When someone has Parkinson’s disease, dopamine levels are low. So, the body doesn’t get the right messages it needs to move normally.

Experts agree that low dopamine levels in the brain cause the symptoms of Parkinson’s disease, but no one really knows why the nerve cells that produce dopamine get damaged and die.

Obtaining A Parkinson’s Disease Diagnosis

During the exam, the neurologist will look for cardinal symptoms of the disease. Facial expressions and features will be assessed. The doctor will look for signs of tremor while the patient is at rest. The doctor may watch how easily the patient stands up from sitting in a chair. The doctor may also stand behind the patient and gently pull back on the patients shoulders and look for how easily the patient can regain balance. Good responsiveness to levodopa also helps support the diagnosis of PD. However, taking levodopa may exclude patients from clinical studies that need to recruit recently diagnosed patients who have not yet had treatment . Participation in a clinical trial should be discussed with the doctor.

PD can be challenging to accurately diagnose, particularly in early stages of the disease, which is why a neurologist trained in movement disorders is critical. Approximately 5-10% of patients with PD are misdiagnosed, as many of the symptoms of PD are similar to other diseases. If the patient thinks that he or she has been misdiagnosed, a second opinion may help.1,2

Perfume Ingredient Offers Hope For Parkinsons Disease

More research is needed to explore the potential of farnesol, a compound commonly used to flavour food and make perfume.

A compound that occurs naturally in herbs, berries and other fruits was able to prevent and even reverse the effects of Parkinsons disease in early tests on mice, a new study has found.

The research, , found that farnesol, a compound commonly used to flavour food and make perfume, prevents the death of dopamine-producing neurons by deactivating PARIS, a different protein that fosters the gradual progression of Parkinsons. Without the protective effect of these neurons, movement and cognition becomes impaired, giving rise to the tremor, muscle rigidity, confusion and dementia associated with the progressive disorder.

By blocking PARIS, farnesol opens the door to new interventions that target and alter the ability of the protein to do lasting damage. Our experiments showed that farnesol both significantly prevented the loss of dopamine neurons and reversed behavioural deficits in mice, indicating its promise as a potential drug treatment to prevent Parkinsons disease, said Ted Dawson, director of the Johns Hopkins Institute for Cell Engineering and professor of neurology at the Johns Hopkins University School of Medicine.

How Is Parkinsons Diagnosed

Doctors use your medical history and physical examination to diagnose Parkinson’s disease . No blood test, brain scan or other test can be used to make a definitive diagnosis of PD.

Researchers believe that in most people, Parkinson’s is caused by a combination of environmental and genetic factors. Certain environmental exposures, such as pesticides and head injury, are associated with an increased risk of PD. Still, most people have no clear exposure that doctors can point to as a straightforward cause. The same goes for genetics. Certain genetic mutations are linked to an increased risk of PD. But in the vast majority of people, Parkinsons is not directly related to a single genetic mutation. Learning more about the genetics of Parkinsons is one of our best chances to understand more about the disease and discover how to slow or stop its progression.

Aging is the greatest risk factor for Parkinsons, and the average age at diagnosis is 60. Still, some people get PD at 40 or younger.

Men are diagnosed with Parkinsons at a higher rate than women and whites more than other races. Researchers are studying these disparities to understand more about the disease and health care access and to improve inclusivity across care and research.

What Is Essential Tremor And How Is It Different To A Parkinsons Tremor

Pin on Diagnosis of Parkinson

A tremor is a rhythmical, involuntary movement that affects a part of the body, such as the hand.

Essential tremor is the most common type of tremor. Its most noticeable when your hands are doing something and it usually affects both the right and left sides of the body equally. Essential tremors often lessen when your body is resting.

Unlike an essential tremor, a Parkinsons tremor is most obvious when the affected body part is resting and tends to be less noticeable with movement. It usually starts on one side of the body and may progress to the other side as Parkinsons develops.

The time it takes to get a diagnosis can vary from person to person. Some people may receive a diagnosis of Parkinsons quite quickly, but for others it may be a long process. This can be due to a number of things, including your medical history, your age and what symptoms you have.

Your specialist may wish to rule out other causes of your symptoms first and see how you respond to treatment. This may take some time, and, as already mentioned, there is currently no definitive test for Parkinsons.

How you respond to treatment may help your specialist make a diagnosis. Keeping a diary or record of your symptoms will give the specialist more information to guide their decision.

Because the symptoms of Parkinsons are sometimes similar to other forms of parkinsonism, people can sometimes be misdiagnosed.

What Is Parkinsons Disease

Parkinsons disease is a nervous system disease that affects your ability to control movement. The disease usually starts out slowly and worsens over time. If you have Parkinsons disease, you may shake, have muscle stiffness, and have trouble walking and maintaining your balance and coordination. As the disease worsens, you may have trouble talking, sleeping, have mental and memory problems, experience behavioral changes and have other symptoms.

How A Diagnosis Is Made

The bedside examination by a neurologist remains the first and most important diagnostic tool for Parkinsons disease . Researchers are working to develop a standard biological marker such as a blood test or an imaging scan that is sensitive and specific for Parkinsons disease.

A neurologist will make the diagnosis based on:

  • A detailed history of symptoms, medical problems, current and past medications. Certain medical conditions, as well as some medications, can cause symptoms similar to Parkinsons.
  • A detailed neurological examination during which a neurologist will ask you to perform tasks to assess the agility of arms and legs, muscle tone, gait and balance, to see if:
  • Expression and speech are animated.
  • Tremor can be observed in your extremities at rest or in action.
  • There is stiffness in extremities or neck.
  • You can maintain your balance and examine your posture.
  • You may notice that a neurologist records your exam into a table, called Unified Parkinsons Disease Rating Scale . This is a universal scale used by neurologists and movement disorder specialists to comprehensively assess and document the exam of a person with PD at a baseline, judge the effect of medication and track the progression of disease during future visits.
  • Most commonly, people with PD respond well to dopaminergic medications. Lack of response to medications may prompt the doctor to seek an alternative diagnosis such as atypical parkinsonism and order further testing such as an MRI of the brain.

    Learn The Protocol For Your State

    Colorado is not a medically mandated state. Its a self-reporting state, which means its up to you to assess whether or not you are fit to drive. With that said, Dittmar says that approximately 75% of the driving assessments she does are direct referrals from doctors.

    Once Dittmar has completed a driving assessment, she sends the report to the drivers doctor and it gets linked back to the drivers DMV profile. The recommendations then become connected to a license.

    These recommendations must be measurable. For example, some of the restrictions that could be placed on a driver include:

    • Can only drive in daylight
    • Can only drive within a certain radius of their home
    • Can only drive below certain speeds

    In some states, the report gets sent to the medical board. Contact the DMV in your state to learn more about how its done where you live.

    When Should Genetic Testing Be Done

    Simple Breath Test Could Help Detect Parkinson’s Disease

    Your physician may suggest it if your Parkinsons diagnosis comes at a young age , if multiple relatives in your family history have also been diagnosed with the same, or if you are at high risk for familial Parkinsons based on your ethnicity .

    However, what is the benefit of having the testing done at the present time? The information may be important for family planning for some individuals although as I said even if the gene is passed on it does not necessarily equal development of the disease. The risk, though, is higher in dominant genetic mutations versus recessive ones, on average if a person has a first-degree relative with Parkinsons their risk of developing the disease is 4 to 9 percent more than the general population.

    Keep in mind that currently for the person being tested, there is no change in the treatment of their Parkinsons disease based on genetic findings. In the future, however, when there are treatments to slow down the onset of the disease or to prevent it from developing at all, then the identification of those people at risk will be very important.

    Drug Therapy And Research

    If the disease progresses beyond minor symptoms, drug treatment may be indicated. Drug therapy for Parkinsonâs typically provides relief for 10â15 years or more. The most commonly prescribed medication is L-dopa , and this helps replenish some of the depleted dopamine in the brain. Sinemet, a combination of levodopa and carbidopa, is the drug most doctors use to treat Parkinsonâs disease. Recent clinical studies have suggested, in the younger person, the class of drugs called âdopamine agonistsâ should be used prior to levodopa-carpidopa except in patients with cognitive problems or hallucinations. In those older than 75, dopamine agonists should be used cautiously because of an added risk of hallucinations.

    Other drugs are also used, and new drugs are continually being tested. It is common for multiple drugs to be prescribed because many of them work well together to control symptoms and reduce side effects. Contrary to past beliefs, starting Sinemet in newly diagnosed people does not lead to early symptoms of dyskinesia . Current knowledge is that the disease progression causes dyskinesias, not a âresistanceâ to the drug.

    Quality of life studies show that early treatment with dopaminergic medications improves daily functioning, prevents falls, and improves a personâs sense of well-being.
