Approaches To Pain Assessment

Fatigue and Sleepiness in Parkinsons Disease

When assessing pain in patients with PD, using a validated pain scale that targets symptoms specific to PD whenever possible will more accurately categorize pain type. The first pain tool designed specifically for patients with PD is the Kings PD Pain Scale .4,12 This scale has 14 questions that measure severity and frequency of different types of pain specific to PD. A complementary patient screening tool, the Kings College PD Pain Questionnaire , is designed for assessing whether or not specific pain types are present. All questions on the KPPQ correspond with a specific question on the KPPS. Screening patients with the KPPQ can facilitate identifying pain types that correspond to the KPPS assessment tool.

If unable to assess pain with scales specific to PD, validated general pain scales, such as the Likert scale, can be utilized to determine quality and severity of any type of pain.18 Using PD-specific pain scales may better characterize a patients pain symptoms, however, which may lead to more targeted treatment options.

Extraction Of Region Of Interest Data

To extract region of interest data we used a standard object map in MNI space. The standard object map contained regions defined for caudate nucleus, putamen, ventral striatum, thalamus and median raphe. These regions of interest had been freehand-traced using ANALYZE 8.1 software onto the single subject MRI in MNI space available in SPM. The same standard object map was applied to each spatially normalized image of 18F-dopa Ki or 11C-DASB BPND and corresponding ADD images. Visual inspection of each plane for both images was made to ensure correct placement of the object regions over the correspondent structures. After applying target regions to structures, 18F-dopa Ki and 11C-DASB BPND values were quantified using ANALYZE 8.1. 18F-dopa Ki and 11C-DASB BPND values obtained from the different regions of interest were averaged over both hemispheres for statistical analysis.

Pathophysiology Of Fatigue In Pd

Most of the evidence suggests that fatigue is an intrinsic symptom to the pathobiological substrate of PD rather than a secondary or reactive phenomenon. For instance, it may precede motor symptoms in a substantial number of patients with PD. In most patients, fatigue did not correlate with PD duration or motor disability,, although some studies indicated that it worsened with underlying disease progression., , However, the interpretation of fatigue in PD is significantly confounded by its clustering with depression, anxiety, sleep disturbances, and apathy. Although it was present in over a onehalf of nondepressed patients with PD and in at least onethird of drugnaive patients in the initial motor stage of the disease, fatigue in PD was related to the severity of depressive symptoms., Fatigue was 1 of the diagnostic criteria for a Diagnostic and Statistical Manual of Mental Disorders, 4th editionbased diagnosis of both major depressive episode and generalized anxiety disorder. However, it is still not clear whether the observed overlaps of fatigue with affective disorders and apathy reflect a diagnostic bias or common pathophysiological mechanisms. A concept of primary fatigue and secondary fatigue has been proposed. In general, it is distinguishable from other related symptoms, such as depression, apathy, and sleepiness, suggesting that fatigue in patients with PD is largely a primary symptom and is not secondary to mood disorders, sleep alterations, or medications.

Causes Of Fatigue In Parkinsons Disease

Early warning signs of parkinsons disease

Many of the symptoms of PD, including slow movement, muscle stiffness, depression, and changes to sleep quality can cause or worsen the symptom of fatigue.

  • Akinesia Fatigue may be caused by akinesia . People experiencing akinesia find it challenging to accomplish simple tasks, requiring significantly more energy to get through the daily activities.
  • Muscle fatigue Many of the symptoms of PD that affect the muscles, like stiffness, cramping, tremor, and difficulty starting movement, put extra stress on the muscles, causing fatigue. In addition, some people with PD experience muscle atrophy, in which the muscles shrink and weaken due to lack of use. Muscle atrophy decreases a persons stamina and endurance, contributing to the sense of fatigue.
  • Depression Depression is another common non-motor symptom of PD, occurring in approximately 40% of people with PD. Depression can cause fatigue, adding to a sense of low energy or lack of motivation.
  • Sleep disturbance PD often causes changes in sleep cycles, which can add to a sense of fatigue during the day.
  • Medications Some of the medications used to treat PD, including dopamine agonists, can cause fatigue as a side effect. Others may cause insomnia as a side effect, leading to daytime fatigue.1,2

Fatigue can make motor symptoms, like tremors, seem like they are worst when they are not. Dr. De León has a list of eight things you can do to prevent or improve fatigue, If you still have severe fatigue discuss it with your physician because there are some medications which can help. The key is well adjusted medications, exercise, good nutrition, and rest at least 5 minutes every day.

Methylphenidate Use For Fatigue In Parkinsons

Methylphenidate , better known by its brand name, Ritalin, is popular for its use in the treatment of children with ADHD. It was FDA approved in the 1950s and became increasingly prescribed in the 1990s. MP has since been used for other disorders, including narcolepsy, refractory depression and fatigue caused by medical and neurological disorders.

Fatigue in Parkinsons is a common problem encountered by one-third to one-half of people with the disease. Parkinsons fatigue is often unrelated to the disease severity and overall motoric disability. Medications used to treat the motor symptoms of Parkinsons typically do not improve fatigue, and treatment specific to fatigue is lacking.

MP is a psychostimulant which has seen an increase in off-label use to treat Parkinsons fatigue. MP works by decreasing the reuptake of neurotransmitters, like dopamine and norepinephrine, thus making them available longer in the synaptic cleft where the chemicals can act on the receiving brain cells.

Based on their clinical experience, many physicians are recommending that patients try MP for Parkinsons fatigue, especially when quality of life is greatly impacted.

MP is an old drug that may have newer uses it may have potential to help people with Parkinsons. As with all medications, discuss the risks and benefits of MP with your neurologist and other healthcare team members before deciding if it is right for you.

Tips For Coping With Fatigue

Fatigue in Parkinson Disease
  • Exercise. Walk, do Tai Chi, dance, cycle, swim, do Yoga or chair Yoga whatever you enjoy. Fatigue may make it hard to start exercising, but it may make you feel more energetic afterward. If you find it difficult to get going, consider exercising with another person or a group.
  • Keep a regular sleep schedule. If you have difficulty sleeping because of tremor or stiffness, trouble rolling over or needing to use the bathroom, talk to your doctor about these issues.
  • Take a short nap after lunch. Avoid frequent naps, long naps, or napping after 3 p.m.
  • Stay socially connected.
  • Pace yourself: plan your day so that you are active at times when you feel most energetic and have a chance to rest when you need to.
  • Do something fun: visit with an upbeat friend or pursue a hobby.
  • At work, take regular short breaks.

Fatigue has been identified by the PD community as an unmet need. Research to understand and solve fatigue in PD is ongoing.

1. Introduction

Parkinsons is a progressive neurological condition, and it is estimated that one in every 350 people in the UK are diagnosed with the condition. Although pharmaceutical interventions are the primary treatment option, exercise is becoming increasingly recognised as an effective addition to commonly used drug treatments for the control of both motor and nonmotor symptoms . There is strong evidence supporting beneficial effects of exercise programs on disease progression, motor and nonmotor symptom management, and health and wellbeing in PwP . Exercise interventions and a dose of 30 minutes or more a week of moderate to vigorous physical activity have been suggested to positively impact on the global nonmotor symptom burden including depression, apathy, fatigue, daytime sleepiness, sleep, and cognition . However, the evidence supporting a positive benefit of exercise to physical activity, fatigue, daytime sleepiness, and sleep is not strong .

What Causes Fatigue In Parkinsons

The precise mechanisms that cause fatigue are unclear but research suggests that any neurological disorder which involves the basal ganglia area of the brain is likely to be associated with significant fatigue. This includes Parkinsons.

In some cases Parkinsons medication may be a factor, for example dopaminergic medications may affect sleep and so add to fatigue. Dosage and timing of medication may also affect energy levels.

Fatigue may be linked to other Parkinsons symptoms, for example depression. With depression there is usually also fatigue, as well as loss of motivation, a general lack of interest and difficulty in sleeping. It is important that these symptoms are recognised as they are very treatable, and overcoming them can reduce fatigue.

If you experience tremor, rigidity or dyskinesia your muscles will have to work harder in order to carry out simple movements or tasks which can mean muscles fatigue more quickly and easily. Slowness of movement may also increase fatigue by making activities and tasks more prolonged and effortful.

You may have sleep problems and poor quality sleep tends to lead to excessive day-time sleepiness and a tendency to nap. Although sleepiness is a separate symptom to fatigue, it clearly adds to the problem and fatigue is hard to overcome if you are sleepy.

Exercise And Medical Interventions

Research has demonstrated the benefits of exercise for patients with PD. Not only have exercise programs been shown to improve motor function and reduce the risk of falls, but they also improve overall quality of life and possibly slow the course of the disease.

Fatigue is associated with lower diastolic blood pressureFatigue is a common debilitating symptom in PD. A 2019 study by researchers at the VA Ann Arbor Health Care System and University of Michigan found that symptoms of fatigue in PD patients were associated with small reductions in diastolic blood pressure throughout the day. Diastolic blood pressure measures pressure in the arteries when the heart rests between beats.

The investigators assessed hourly home blood pressures in 35 people with PD. They then asked the study participants to describe any symptoms of fatigue. The patients with fatigue symptoms had lower mean diastolic blood pressure than those without. The differences in pressure were most notable in the morning.

Fatigue is a complex condition. Understanding the mechanisms that underlie PD fatigue can help scientists find new treatment approaches, wrote the researchers. Fatigue experienced by PD patients could be a clinical manifestation of low blood pressure, they say.

Researchers taught an adapted version of the Argentine tango to 20 people with mild to moderate PD. Over three weeks, participants completed 15 dance lessons, each lasting 90 minutes.

What Is The Va Rating For Parkinsons Disease

7 Ways to Help Fatigue in Parkinson

One of the questions we often field is, Is Parkinsons disease a 100% compensation disability? The VA Parkinsons disability rating can rise to 100%. However, it is not 100% by default.

Instead, the Parkinsons VA disability rating has a minimum or default rating of 30%, but that is just the starting point. When you apply for VA Parkinsons disability benefits, the VA looks at two numbers.

First, it looks at your individual disability rating using the aforementioned formula. Then, it compares that number to the default or overall disability rating for Parkinsons disease, which is 30%. If your individual disability rating exceeds 30%, that is your disability rating.

In that way, your disability rating can reach 100%. Conversely, if your personal disability rating is, for example, 22%, you will instead receive a combined rating of 30%.

Physiology And Biomarkers For Fatigue In Pd

The physiology underlying fatigue symptoms in PD is unknown, whereas much is known about the mechanisms of motor fatigability. The only published study of physiological differences between fatigued and nonfatigued PD patients found no measurable differences in oxygen utilization during exercise, but some studies have suggested that exercising improves fatigue.,,, Whether fatigue fluctuates with motor fluctuations was looked at in one study. Subjects were assessed during their off, whereas all other studies used the subjects experience over a preceding time interval of weeks. Eighty-eight percent of their subjects were fatigued, and fatigue increased with motor off. Too few subjects were nonfatigued to determine how often fatigue occurred only during motor off. The physiological implications are unclear, as many other nonmotor symptoms also increased during the off period.

Treatment For Fatigue In Parkinson’s Disease

At least one-third of people with Parkinson’s disease complain about fatigue. It is unclear what treatment is best to reduce fatigue in people with Parkinson’s disease.

We reviewed the medical literature up to April 2015, and found 11 studies that included a total of 1817 people. Nine studies investigated the effects of medication on fatigue. Two studies investigated the effects of exercise on fatigue. We found no studies that investigated the effect of cognitive-behavioural therapy.

We found that doxepin , a drug to treat depression, may reduce fatigue. We found that rasagiline , an anti-Parkinson drug, reduced or slowed down the progression of physical fatigue. Most drugs were safe however, levodopa-carbidopa may cause nausea.

We found no evidence that exercise reduces fatigue in Parkinson’s disease.

Based on the current evidence, it is not clear what treatment is most effective to treat fatigue in people with Parkinson’s disease. Future studies should investigate the effect of cognitive-behavioural therapy on fatigue in people with Parkinson’s disease.

Factors contributing to subjective fatigue in people with idiopathic Parkinsons disease are not well known. This makes it difficult to manage fatigue effectively in PD.

Insights Into Fatigue From Other Disorders

Parkinson’s Disease (Shaking Palsy) – Clinical Presentation and Pathophysiology

Although perceived fatigue is probably similar among different illnesses, there may be disease-specific differences. Both similarities and differences may provide insights into fatigue pathophysiology. Similarities in fatigue would be compatible with a hypothesis of shared mechanisms, and thus the possibility of similar interventions. The high prevalence of fatigue in medical and psychiatric disorders points either to some very generalized mechanisms or a limitation in the brains ability to distinguish perceptions. We limited our review of other disorders with prominent fatigue, but excluded chronic fatigue syndrome because of its frequent association with psychiatric disorders such as personality disorders and post-traumatic stress disorder that might confound physiological interpretations.
