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.
How Is Tremor Classified
Tremor can be classified into two main categories:
Resting tremor occurs when the muscle is relaxed, such as when the hands are resting on the lap. With this disorder, a persons hands, arms, or legs may shake even when they are at rest. Often, the tremor only affects the hand or fingers. This type of tremor is often seen in people with Parkinsons disease and is called a pillrolling tremor because the circular finger and hand movements resemble rolling of small objects or pills in the hand.
Action tremor occurs with the voluntary movement of a muscle. Most types of tremor are considered action tremor. There are several sub-classifications of action tremor, many of which overlap.
- Postural tremor occurs when a person maintains a position against gravity, such as holding the arms outstretched.
- Kinetic tremor is associated with any voluntary movement, such as moving the wrists up and down or closing and opening the eyes.
- Intention tremor is produced with purposeful movement toward a target, such as lifting a finger to touch the nose. Typically the tremor will become worse as an individual gets closer to their target.
- Task-specific tremor only appears when performing highly-skilled, goal-oriented tasks such as handwriting or speaking.
- Isometric tremor occurs during a voluntary muscle contraction that is not accompanied by any movement such as holding a heavy book or a dumbbell in the same position.
Causes Of Parkinson’s Disease
Parkinson’s disease is caused by a loss of nerve cells in part of the brain called the substantia nigra. This leads to a reduction in a chemical called dopamine in the brain.
Dopamine plays a vital role in regulating the movement of the body. A reduction in dopamine is responsible for many of the symptoms of Parkinson’s disease.
Exactly what causes the loss of nerve cells is unclear. Most experts think that a combination of genetic and environmental factors is responsible.
Parkinson’s Disease Symptoms: Life Expectancy
Even though Parkinson’s disease is a serious, progressive condition, it is not considered a fatal illness. People who have Parkinson’s disease usually have the same average life expectancy as people without the disease.
But when the disease is in its advanced stages, Parkinson’s symptoms can lead to life-threatening complications, including:
- Falls that lead to fractured bones
- Pneumonia
- Choking
Thinking about the progression of Parkinson’s disease can be frightening. But proper treatments can help you live a full, productive life for years to come. And researchers hope to one day find ways to halt the progression of Parkinson’s and restore lost functioning.
Take Care Of Yourself
Probably one of the most important, and sometimes difficult, things caregivers can do is to take care of themselves. This includes maintaining mental and physical health by making and keeping your own medical and dental appointments. As a caregiver, it is important to keep your job whenever possible as it provides not only financial help and possibly insurance coverage, but also a sense of self-esteem. Join a support group for caregivers if possible. Support groups help you meet people who are going through what you are going though, vent frustrations, give and receive mutual support, and exchange resource information and coping strategies. Whenever possible get your sleep, take breaks, make and keep social activities, and try to keep your sense of humor.
Changes In Sleeping Patterns
As Parkinsons progresses, you can also develop problems with sleep patterns. These may not happen in the early stages, but can be noticeable later. You might wake up often in the middle of the night or sleep more during the day than you do at night.
Another common sleep disturbance for people with Parkinsons is rapid eye movement sleep behavior disorder. This is when you start acting out your dreams in your sleep, such as verbally and physically, which can get uncomfortable if someone is sharing your bed. Dr. Rundle-Gonzalez says many times a bed partner will be the one to notice sleep problems.
REM sleep behavior disorder can also happen in people who dont have Parkinsons. However, if this isnt something youve dealt with before, its likely related to your disease. There are medications your doctor can prescribe to help you sleep comfortably through the night.
Why It Is Hard To Detect The Progression Of Parkinsons Disease
As we stated above that Parkinsons disease is not basic, it becomes difficult to detect it in its early stage due to 2 symptoms it affects motor issues such as the rigid muscles and tremors, and the other is the development of non-motor symptoms such as dementia, pain, and loss of smell.
Although one cannot see that a person suffering from Parkinsons disease will show all the symptoms, you cannot even tell or predict which symptoms will be present and their severity. For instance, one patient may show severe dementia with slight tremors. Another patient displays a critical condition of tremors but does not have any problem related to memory or thinking. In another case, the patient can show a severe state of all the symptoms. Therefore, it is difficult to predict the progression of the condition.
In addition to this, the medicines that help in treating Parkinsons disease also make it difficult to predict the results because a few patients show positive results while others do not show any improvement.

Theories About What Causes Parkinsons
The cause of Parkinsons disease is still unknown, although there is some evidence for the role of genetics, environmental factors, or a combination of both. It is also possible that there may be more than one cause of the disease. Scientists generally believe that both genetics and environment interact to cause Parkinsons disease in most people who have it.
Currently, there is an enormous amount of research directed at producing more answers about what causes Parkinsons disease and how it might be prevented or cured. When physicians diagnose Parkinsons, they often describe it as idiopathic . This simply means that the cause of the disease is not known.
What It Looks Like:
You feel a general level of physical or mental exhaustion that stretches beyond normal tiredness. Just starting any workout is an accomplishment due to your utter lack of energy and motivation. When you do manage to exercise, youre wiped out. You may notice walking seems incredibly difficult, due to heaviness in your legs or extreme freezing. Exercise is such an endeavor that youre tempted to just avoid it altogether.
Determining Diagnosis Through Response To Parkinsons Medication
If a persons symptoms and neurologic examination are only suggestive of Parkinsons disease or if the diagnosis is otherwise in doubt, the physician may, nevertheless, prescribe a medication intended for Parkinsons disease to provide additional information. In the case of idiopathic Parkinsons, there is typically a positive, predictable response to Parkinsons disease medication; in the case of some related Parkinsonian syndromes, the response to medication may not be particularly robust, or it may be absent entirely.
Unfortunately, there are no standard biological tests for the disease, such as a blood test. However, researchers are actively trying to find biomarkers in blood and other bodily fluids that could help confirm the diagnosis.
Parkinsons Disease Symptoms Of Dementia
Up to one-third of people living with Parkinson’s disease experience dementia, according to the Parkinson’s Disease Foundation. Problems with dementia may include trouble with memory, attention span, and what is called executive function the process of making decisions, organizing, managing time, and setting priorities.

Is There A Way To Slow The Progress Of Parkinson’s
Parkinson’s disease is a progressive disorder, which means its symptoms worsen slowly over time. There is no cure for Parkinson’s disease yet and no known way to slow its progress.
But there are treatments and medications that can control or reduce the symptoms and help people live productive lives. Some research suggests that regular exercise may slow the progress of Parkinson’s. Physical activity can also alleviate stiffness and other symptoms.
There are other things a person can do to feel better after a diagnosis of Parkinson’s, such as joining social support groups and learning as much as possible about the disease. It’s also important to make the home safer and less cluttered, since a person with Parkinson’s is more likely to fall.
While it’s not always easy, neurologists say a positive mindset can also help.
Who Is Affected By Tremor
About 70% of people with Parkinsons experience a tremor at some point in the disease. Tremor appears to be slightly less common in younger people with PD, though it is still one of the most troublesome symptoms. People with resting tremor usually have a more slowly progressing course of illness than people without tremor.
Surgery And Deep Brain Stimulation
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:
Tremor In Other Conditions
While tremor is a common symptom of Parkinsons, it can also be a symptom of other conditions, most notably essential tremor. The main difference between Parkinsons tremor and most other types of tremor is that in Parkinsons resting tremor is most common. Other conditions are usually characterized by action tremor, which tends to lessen at rest and increase when youre doing something, like trying to make a phone call or take a drink.
Tremors of the head and voice are also common in essential tremor but rare in Parkinsons.
What Causes Parkinson’s Disease
Parkinson’s disease occurs when nerve cells, or neurons, in an area of the brain that controls movement become impaired and/or die. Normally, these neurons produce an important brain chemical known as dopamine. When the neurons die or become impaired, they produce less dopamine, which causes the movement problems of Parkinson’s. Scientists still do not know what causes cells that produce dopamine to die.
People with Parkinson’s also lose the nerve endings that produce norepinephrine, the main chemical messenger of the sympathetic nervous system, which controls many functions of the body, such as heart rate and blood pressure. The loss of norepinephrine might help explain some of the non-movement features of Parkinson’s, such as fatigue, irregular blood pressure, decreased movement of food through the digestive tract, and sudden drop in blood pressure when a person stands up from a sitting or lying-down position.
Many brain cells of people with Parkinson’s contain Lewy bodies, unusual clumps of the protein alpha-synuclein. Scientists are trying to better understand the normal and abnormal functions of alpha-synuclein and its relationship to genetic mutations that impact Parkinsons disease and Lewy body dementia.

What Is The Outlook For Persons With Parkinsons Disease
Although there is no cure or absolute evidence of ways to prevent Parkinsons disease, scientists are working hard to learn more about the disease and find innovative ways to better manage it, prevent it from progressing and ultimately curing it.
Currently, you and your healthcare teams efforts are focused on medical management of your symptoms along with general health and lifestyle improvement recommendations . By identifying individual symptoms and adjusting the course of action based on changes in symptoms, most people with Parkinsons disease can live fulfilling lives.
The future is hopeful. Some of the research underway includes:
- Using stem cells to produce new neurons, which would produce dopamine.
- Producing a dopamine-producing enzyme that is delivered to a gene in the brain that controls movement.
- Using a naturally occurring human protein glial cell-line derived neurotrophic factor, GDNF to protect dopamine-releasing nerve cells.
Many other investigations are underway too. Much has been learned, much progress has been made and additional discoveries are likely to come.
How Long Does It Take For Parkinsons Disease To Progress
It is quite common for any individual suffering from Parkinsons disease to wonder about the unfolding of the condition. If you belong to the group that in search for the answers related to the progression of Parkinsons disease, then you will try to learn about the symptoms that you can acquire with the condition, when they start, and the changes the disease brings in the body.
The questions are basic, but Parkinsons disease is not. Like other illnesses, Parkinsons disease does not have a specific path of progression. Due to this, it is difficult to state or pin down the exact time or the path of the progression.
What Are The Symptoms Of Tremor
Symptoms of tremor may include:
- a rhythmic shaking in the hands, arms, head, legs, or torso
- shaky voice
- difficulty writing or drawing
- problems holding and controlling utensils, such as a spoon.
Some tremor may be triggered by or become worse during times of stress or strong emotion, when an individual is physically exhausted, or when a person is in certain postures or makes certain movements.
What Does This Mean For Me If I Have Essential Tremor
There is compelling evidence that cognition differs between people with and without an essential tremor. Those differences, however, are slight, and the cause of those changes is unclear. If essential tremor is, in fact, a degenerative illness, it’s very slow. How this all relates, if at all, to patient care is unclear at this time. Perhaps identifying more serious causes of essential tremor could end up benefiting people who would otherwise be written off as having an entirely benign disorder.

Confusion With Essential Tremor
The tremor of Parkinsons disease is often confused with the tremor of a condition called Essential Tremor, or Benign Familial Tremor . Katherine Hepburn had Essential Tremor, and was originally misdiagnosed with Parkinsons. Ronald Reagan also had Essential Tremor. Both had a head tremor and a vocal tremor. In Essential Tremor, the hands are most commonly involved, followed by the head and then the voice. Essential Tremor can also cause the jaw to tremor, and it may be difficult to figure out if a jaw tremor is from Essential Tremor or Parkinsons. Unfortunately, some people may have both disorders. Some authorities believe that there is, in fact, an increased association between the two conditions, so that more people with Parkinsons disease have Essential Tremor than would be expected by chance alone, but this has not been established.
Parkinsons Disease Can Be Misdiagnosed
In the early stages, it can be difficult to diagnose Parkinsons disease. The early symptoms of the disease can come and go. You might think you are just stiff or having cramps. Or, you might think that this is just part of the aging process. But if the symptoms keep on coming back, you will eventually go to the doctor. He may tell you that it may take more time before he can make a definite diagnosis. This can lead to much anxiety, of course.
If you think you might have Parkinsons disease, below are some things to keep in mind, especially if your doctor has not yet diagnosed you. Remember, diagnosing PD can be hard, even for a highly trained neurologist:
- There are no blood tests or lab tests that can diagnose the disease for certain. It is usually diagnosed based upon medical history, a clinical exam and symptoms.
- Four typical signs of PD are rigidity, slow movement, tremors and postural instability. If you are experiencing these symptoms, especially if they began on one side of the body, your doctor may diagnose you with the disorder.
Note that even if you have three classic symptoms of PD, you still may not have it! To decrease the chance that you will be misdiagnosed, your doctor may have you take several drugs that treat Parkinsons such as levodopa. If your symptoms get better when you take the drug, you probably have PD. If you do not get better after a period of levodopa therapy, your tremors may be due to another cause.
PD and Progressive Supranuclear Palsy
Who Gets Parkinsons Disease
Parkinsonâs disease, documented in 1817 by physician James Parkinson, is the second most common neurodegenerative disease after Alzheimerâs disease. Estimates regarding the number of people in the United States with Parkinsonâs range from 500,000 to 1,500,000, with 50,000 to 60,000 new cases reported annually. No objective test for Parkinsonâs disease exists, so the misdiagnosis rate can be high, especially when a professional who doesnât regularly work with the disease makes the diagnosis.
Behaviors Seen In Parkinsons Disease Dementia
As dementia progresses, managing disorientation, confusion, agitation, and impulsivity can be a key component of care.
Some patients experience hallucinations or delusions as a complication of Parkinsons disease. These may be frightening and debilitating. Approximately 50 percent of those with the disease may experience them.
The best thing to do when giving care to someone experiencing hallucinations or delusions from Parkinsons disease dementia is to keep them calm and reduce their stress.
Take note of their symptoms and what they were doing before they exhibited signs of hallucinating and then let their doctor know.
This element of the disease can be particularly challenging for caregivers. Patients may become unable to care for themselves or be left alone.
Some ways to make caregiving easier include:
- sticking to a normal routine whenever possible
- being extra comforting after any medical procedures
- limiting distractions
- using curtains, nightlights, and clocks to help stick to a regular sleep schedule
- remembering that the behaviors are a factor of the disease and not the person
How Do Symptoms Progress
The most common symptoms of Parkinson’s are tremor, rigidity and slowness of movement.
Not everyone with Parkinson’s experiences the same combination of symptoms they vary from person to person.
Also, how Parkinson’s affects someone can change from day to day, and even from hour to hour. Symptoms that may be noticeable one day may not be a problem the next.
Many of the symptoms can be treated or managed with medication and therapies.
Many people with Parkinson’s lead active and fulfilling lives. An important part of coping with Parkinson’s is understanding how it affects you and how to work around it.
It may not always be easy to maintain a positive outlook, especially immediately after diagnosis. But we can give you help and support.
Caregiving For People Living With Parkinsons
Caring for a loved one with PD can be a challenging job, especially as the disease progresses. Former caregivers of a loved one with PD suggest doing the following : Get prepared, Take care of yourself, Get help , Work to maintain a good relationship with your loved one, and Encourage the person with PD for whom you care, to stay active.
Preparing for caregiving starts with education. Reading this fact sheet is a good start. More resources are available to you in theResources section of this fact sheet. Early Parkinsonâs disease usually requires more emotional support and less hands-on care. It is a good time for family members/caregivers to educate themselves about the disease.
Embarrassing Symptoms Of Parkinson’s Disease
Some symptoms that may occur in people with Parkinsons disease are not typical of it and so people noticing them may misunderstand them. These symptoms can be particularly embarrassing in social situations where other people witness their discomfort. They distress some people so much that they avoid company other than close friends or family. Most of these symptoms are caused by Parkinsons but some are side effects of the medicines used to treat it. All the symptoms tend to fluctuate in relation to the medication, and some people had learnt to adjust their medicine regime to minimise these effects.
Eating can cause embarrassment in several ways. Both tremor and dyskinesia affect the physical job of cutting up food and directing it into the mouth . Several people had a problem with a piece of steak or chicken that might fly off the plate as they tried to cut it up, or they had a choking fit if they unwisely took too big a piece into their mouth. Humphrey disliked eating out with friends because he tended to drop things.
Memory Or Thinking Problems
Having issues with thinking and processing things could mean your disease is progressing. Parkinsons is more than a movement disorder. The disease has a cognitive part as well, which means it can cause changes in the way your brain works.
During the final stage of the disease, some people may develop dementia or have hallucinations. However, hallucinations can also be a side effect of certain medications.
If you or your loved ones notice that youre getting unusually forgetful or easily confused, it might be a sign of advanced-stage Parkinsons.
Stiffness And Slow Movement
Parkinsons disease mainly affects adults older than 60. You may feel stiff and a little slow to get going in the morning at this stage of your life. This is a completely normal development in many healthy people. The difference with PD is that the stiffness and slowness it causes dont go away as you get up and start your day.
Stiffness of the limbs and slow movement appear early on with PD. These symptoms are caused by the impairment of the neurons that control movement. A person with PD will notice jerkier motions and move in a more uncoordinated pattern than before. Eventually, a person may develop the characteristic shuffling gait.
