The Spectrum Of Off In Parkinsons Disease
Hubert FernandezCleveland Clinic Lerner College of Medicine, Case Western Reserve University, Cleveland, OH, USA
Despite the common nature of wearing-off and the substantial burden it exerts on both the patient and the healthcare system, it remains an under-recognised problem. Potential reasons for this include limited evaluation time for physicians, miscommunication between patients and caregivers, particularly with regard to the reporting of NMS such as cognitive dysfunction and urinary problems, and the lack of an established definition for wearing-off. Current definitions put a heavy emphasis on motor symptoms, potentially missing transition states between ON and OFF periods. This lack of an established definition is reflected in the results of a study by Stacy et al., where clinicians were shown to identify wearing-off in only 29.4% of cases, fewer than specific questionnaires such as the Unified Parkinsons Disease Rating Scale Part IV, Question 36 or the wearing-off patient questionnaire .1 However, even the gold-standard questionnaires are reliant on patient recall and only usually assess symptoms across a single day. It is hoped that with the advent of new mobile technologies it will be possible to assess patients more closely and for longer periods of time.9
Can An Off Episode Be Prevented
Eventually, most people with PD develop OFF episodes. Some people develop OFF episodes sooner than others.
Researchers have found evidence that taking high doses of levodopa may increase your risk of OFF episodes. It may cause greater fluctuations in your dopamine levels.
Its important for your doctor to prescribe the lowest dose of levodopa necessary to manage your symptoms. This may help limit fluctuations in dopamine and reduce your risk of OFF episodes.
If you think you might be experiencing OFF episodes, let your doctor know. They may adjust your prescribed dose or formulation of levodopa/carbidopa. They may also prescribe other treatments to manage OFF episodes.
If youre experiencing OFF episodes, your doctor may recommend one or more changes to your treatment plan.
They may:
In some cases, your doctor may recommend deep brain stimulation . In this procedure, a surgeon implants electrodes in the brain and a small internal pulse generator in the chest or abdomen. The internal pulse generator sends electrical signals to the brain to help control symptoms of DB.
Each treatment option carries a different risk of side effects. Ask your doctor about the potential benefits and risks of different treatment approaches.
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.

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.

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.

Parkinsons Disease Signs And Symptoms
It can be quite difficult to tell if a person is suffering from Parkinsons disease or not because there can be the involvement of multiple symptoms in a single individual. However, if a person suffers from more than one symptoms of Parkinsons disease, he must go for a doctors appointment.
Following are the fifteen symptoms of Parkinsons disease:
Tremors
Shaking of hands or tremors is one of the most common movement related symptoms of Parkinsons disease. When a person feels slight shaking of his hands at rest, then it is an early sign of Parkinsons disease. A person with Parkinsons disease can notice tremors in his hand, fingers, thumb, or even chin. Low dopamine levels can contribute to uncontrollable shaking of body parts. However, slight shaking is normal if a person exercises a lot or is going through stress but repetitive tremors are a sign of Parkinsons disease.
Can Parkinsons Disease Be Prevented
Unfortunately, no. Parkinsons disease is long-term disease that worsens over time. Although there is no way to prevent or cure the disease , medications may significantly relieve your symptoms. In some patients especially those with later-stage disease, surgery to improve symptoms may be an option.

What Types Of Symptoms Might You Experience When Youre Off
Being OFF is more than just having a bad day. It involves experiencing a host of motor and non-motor symptoms that you have come to expect your medication to control.
While the number and severity of symptoms differ for everyone, here are the most common ones people experience when they are OFF:
Motor Symptoms of OFF
- Dystonia in hands, feet or legs
Non-Motor Symptoms of OFF
Many non-motor symptoms remain present in the ON state, and they do not respond to dopaminergic treatment. Therefore, you would not be considered OFF if those remain present. However, there are some non-motor symptoms that worsen or are more severe in the OFF state. These often include:
- Fluctuations in cognition, attention, anxiety, depression, apathy
- Sweating, lightheadedness, abdominal pain, bloating, urinary issues
- Visual disturbances, pain, dysesthesia, akathisia, restless legs syndrome
Why Does My Dog Shake Her Head And Lose Balance
Since the vestibular system is in charge of body balance in a dog, when there is a problem with it, the dog will have a head tilt, loose balance and adopt an unsteady gait. In some cases, the loss of balance may be so severe the dog falls over. Additionally, the dog may be seen walking in circles.
Stimulant drugs called amphetamines also cause shaking as a side effect. Some stimulants treat ADHD and narcolepsy. Others are sold illegally and used recreationally. Other symptoms of caffeine or stimulant overload include: 7. Alcohol Drinking alcohol alters levels of dopamine and other chemicals in your brain.

What Causes On/off Episodes In Parkinson’s Disease
On/off episodes, also known as off time, typically happen more often as Parkinson’s disease progresses, and levodopa becomes less effective.
Carbidopa/levodopa is considered the gold standard in Parkinson’s disease treatment, meaning it’s the most effective for treating motor symptoms, such as tremor, rigidity, and bradykinesia . Levodopa works by crossing the blood-brain barrier and converting into dopamine, low levels of which are believed to be the cause of Parkinson’s symptoms. Adding carbidopa to levodopa helps prevent levodopa from breaking down before it crosses into the brain, which helps reduce side effects like nausea and vomiting.
Some people who have Parkinsons start taking levodopa at around three doses per day. If you start experiencing off episodes, your doctor may increase your dose to four or more times per day.
Off time is common: According to patient surveys, around half of patients who take levodopa report experiencing wearing off periods. Of those patients, 25% experience it 3 to 6 hours per day, and 52% have symptoms for 1 to 3 hours a day.

Implications Of Elusive On
Trials to establish the efficacy of established medications utilizing perhaps more efficient delivery systems have so far failed to prove complete reduction in off-time.
Theres a lot that isnt logical about it, or conceptually, we have the wrong message that off-time is always a deficiency of dopaminergic stimulation to be improved by better delivery of drugs or blocking the breakdown of drugs we currently use, said LeWitt. To him, the emerging story has been that the emergence of Parkinsonian symptoms can be, and is, a complex tale.
You can also criticize the studies, like the TOLEDO study, that maybe they didnt enough apomorphine in the dosing with levodopa, to try to explain why the effect was as limited as it was. But that might not be the right answer to it, LeWitt said. It might just be that theres some black box in the brain that fails to respond fully to continuous dopaminergic stimulation to relieve all of the Parkinsonian symptoms. Im thinking more and more that it might be something weve yet to learn about this disorder, that as the disease goes by the responses to dopaminergic stimulation may fluctuate in a manner that doesnt really suggest what to do about it now.

Facilitators Of Discussing Off Periods
Physician ratings of facilitators to the discussion of OFF periods are shown in . The facilitator most commonly identified by both general neurologists and movement disorders specialists was the presence of a care partner at the clinical visit . A high percentage of general neurologists and movement disorders specialists also already used this strategy for communication . Free-flowing dialogue was the next most commonly reported facilitator in both groups . Again, a high percentage of both physician groups reported already using this method for communication . Incorporating a teach-back technique in communication was identified as a facilitator by a high percentage , but was less commonly implemented as a method of communication . A multidisciplinary approach incorporating allied health personnel such as nurse educators was seen as a facilitator by both groups , but less used by general neurologists than movement disorders specialists .

Does Parkinsons Disease Impair A Patient Cognitively
Since Parkinsons disease is neurological in nature it does have an effect on a patients cognition. Although the symptoms can be seen at a later stage of progression, the cognitive symptoms can be in form of delusions and hallucinations. The patient may also have issues with remembering events and can be diagnosed with dementia.

The Bottom Line On On/off Periods With Parkinsons Meds
Managing the cycling between on and off periods with Parkinsons medications can be incredibly frustrating, but luckily, there are a number of effective ways to help reduce the peaks and valleys of motor symptoms.
Scientists are still exploring new and improved ways to help combat off periods with Parkinsons drugs, according to the Michael J. Fox Foundation for Parkinsons Research. You may even consider participating in one of these clinical trials, which you can learn more about with the Michael J. Fox Foundations clinical trial matching tool.
Even more exciting is the fact that researchers are also working diligently to try to improve Parkinsons treatments in generalreally looking into the crux of the disease to try to slow its progression overall, which would in turn help with this on-off period struggle, says Dr. Hui.
There are a number of clinical trials going on, so I think we should also stay tuned for development of to slow progression of disease, she says.

Parkinsons disease is a disorder involving brain that leads to movement and non-movement symptoms in patients. Some of the commonly occurring symptoms of Parkinsons disease include shaking, stiffness, difficulty while walking, coordination issues, and balance problems. The symptoms of Parkinsons disease typically begin slowly and get worse with time. With the progression of disease, people might suffer from difficulties with speech and walking. In addition, the patients with Parkinsons disease also suffer from behavioral and mental changes that include fatigue, memory issues, depressions, and sleep problems. The incidence of Parkinsons disease is higher than the combined diagnosis of other neurological disorders like Lou Gehrigs disease, muscle dystrophy, and multiple sclerosis.

MJFFs latest resources provide information about the common but sometimes misunderstood experiences of off time in Parkinsons, to help people living with PD and their loved ones feel empowered to learn more and take action in their care, Dolhun added.
The high degree of variability in off episodes experienced by patients often makes it difficult for them and their families to communicate to their doctors adequately. Recently, the MJFF conducted an online clinical study Fox Insight that surveyed 2,000 people with Parkinsons to understand unique off episode experiences.
The results revealed some patients found it challenging to explain their symptoms, and almost half reported troublesome symptoms that standard clinical assessments would miss. The three most common off episode symptoms reported were freezing during walking, memory problems, and apathy, or a lack of motivation.
MJFFs new interactive resources include: first-hand insights by patients about simplifying the complex topic of off episodes video and podcast resources with leading Parkinsons experts who answer common questions concerning episode variability practical tips and strategies to manage off times and how to speak with doctors about appropriate medication regimens. Information about the latest therapies and those in the ongoing research pipeline also is included.
The suite includes personal reflections from people living with Parkinsons who experience off periods.

How Many People Living With Parkinsons Experience Off Periods
It has been reported that within one to two years of beginning levodopa therapy, almost 50% of peoplewith Parkinsons notice that their medication lasts for shorter periods of time. Initially, this was why some doctors choose to delay prescribing Levodopa, a still unresolved debate.
The debate in itself is not the problem at hand, however. The problem is that half of the people living with Parkinsons are experiencing OFF periods and many of them are not getting the relief they need.
Here are five ways you might be able to change that in order to get the best care for you.
What Lifestyle Changes Can I Make To Ease Parkinsons Symptoms
Exercise: Exercise helps improve muscle strength, balance, coordination, flexibility, and tremor. It is also strongly believed to improve memory, thinking and reduce the risk of falls and decrease anxiety and depression. One study in persons with Parkinsons disease showed that 2.5 hours of exercise per week resulted in improved ability to move and a slower decline in quality of life compared to those who didnt exercise or didnt start until later in the course of their disease. Some exercises to consider include strengthening or resistance training, stretching exercises or aerobics . All types of exercise are helpful.
Eat a healthy, balanced diet: This is not only good for your general health but can ease some of the non-movement related symptoms of Parkinsons, such as constipation. Eating foods high in fiber in particular can relieve constipation. The Mediterranean diet is one example of a healthy diet.
Preventing falls and maintaining balance: Falls are a frequent complication of Parkinson’s. While you can do many things to reduce your risk of falling, the two most important are: 1) to work with your doctor to ensure that your treatments whether medicines or deep brain stimulation are optimal and 2) to consult with a physical therapist who can assess your walking and balance. The physical therapist is the expert when it comes to recommending assistive devices or exercise to improve safety and preventing falls.

What Causes Parkinsons Disease
Parkinsons disease occurs when nerve cells in an area of the brain called the substantia nigra become impaired or die. These cells normally produce dopamine, a chemical that helps the cells of the brain communicate . When these nerve cells become impaired or die, they produce less dopamine. Dopamine is especially important for the operation of another area of the brain called the basal ganglia. This area of the brain is responsible for organizing the brains commands for body movement. The loss of dopamine causes the movement symptoms seen in people with Parkinsons disease.
People with Parkinsons disease also lose another neurotransmitter called norepinephrine. This chemical is needed for proper functioning of the sympathetic nervous system. This system controls some of the bodys autonomic functions such as digestion, heart rate, blood pressure and breathing. Loss of norepinephrine causes some of the non-movement-related symptoms of Parkinsons disease.
Scientists arent sure what causes the neurons that produce these neurotransmitter chemicals to die.
Theory Of Pd Progression: Braaks Hypothesis
The current theory is that the earliest signs of Parkinson’s are found in the enteric nervous system, the medulla and the olfactory bulb, which controls sense of smell. Under this theory, Parkinson’s only progresses to the substantia nigra and cortex over time.
This theory is increasingly borne out by evidence that non-motor symptoms, such as a loss of sense of smell , sleep disorders and constipation may precede the motor features of the disease by several years. For this reason, researchers are increasingly focused on these non-motor symptoms to detect PD as early as possible and to look for ways to stop its progression.
