Diagnostic Assessment Of Sleep Disorders In Pd
The history taken from the patient and its neighbors is very important in assessing sleep disorders in PD. The type of sleep disorder should be identified in the history, and information about possible related factors should be obtained from the history. In PD, general and specific scales can be used to investigate the subtype of sleep disorder and to determine its severity. Objective methods can be used to further investigate the diagnosis of these disorders. Further investigative techniques include sleep recording methods such as actigraphy or PSG. Polysomnographic findings of each sleep disorder have been explained in the relevant section. In addition, information about screening scales used in each sleep disorder has been described in the relevant section.
Actigraphy is an electrophysiological device that measures the movements of the patient during sleep by recording from wrist or ankle for many days. Actigraphy evaluates indirectly the circadian sleepwake patterns . It is especially used in circadian rhythm disorders or insomnia and prolonged daytime sleepiness .
The Effect Of Exercise
Exercise has been shown to have a variety of beneficial impacts, and sleep is no exception. In fact, a study found that after four months of physical activity, adult insomniacs got an average of one extra hour of sleep per night. Exercise improves sleep quality, quantity, number of nighttime waking incidents and the time it takes to fall asleep. Sleep also gives you more energy and therefore contributes to a positive feedback loop of more exercise and more sleep.
From preventing against cancer to improving your learning capabilities to making cool-headed decisions, consistent and proper sleep habits can offer a wide range of positive effects. But even if you know how important sleep is, when youre having trouble sleeping, what can you do to fix it?
The number of reported cases of sleep issues has increased dramatically in recent years. There are a variety of underlying causes, as Walker describes:
To date, we have discovered numerous triggers that cause sleep difficulties, including psychological, physical, medical, and environmental factors . External factors that cause poor sleep, such as too much bright light at night, the wrong ambient room temperature, caffeine, tobacco, and alcohol consumption can masquerade as insomnia. -Matthew Walker, 243

Melatonin On Excessive Daytime Sleepiness
Excessive daytime sleepiness is one of the most common non-motor symptoms of PD. It has been reported that most PD patients suffer from excessive daytime sleepiness , which seriously impairs the quality of life of patients with PD . Because of sleep disorders, especially sudden sleep attacks, many activities are dangerous for patients with PD, such as driving a car or operating a machine.
Diagnosis Of Insomnia In Pd
In the diagnosis of insomnia in PD, the clinical history including the stages of insomnia and its associated factors are essential. For example, the factors associated with initial insomnia should be learned from the clinical history because the identification of factors associated with insomnia is necessary for the treatment plan. Table 2 shows the factors associated with insomnia . For example, for the diagnosis of RLS, as a reason for the difficulty of falling into sleep, clinical assessment is sufficient. Thus, patients should be asked for the features in the definition mentioned below for the diagnosis of RLS . In contrast to idiopathic RLS, family history of RLS is less frequent in PD . Polysomnography and actigraphy can be used to detect the objective findings of the insomnia . It has been reported that insomnias PSG findings may be an increase in the number of brief EEG arousalsor arousal index, number of stage shifts to stage 1 or wake, wake time after sleep onset , and percentage of stage 1 sleep . The actigraphic findings of insomnia include the presence of irregularity in sleep onset and increased number of awakening times during the night . One review has been reported that studies comparing PSG to actigraphy in insomnia show that PSG and actigraphy have no significant difference in showing the measurements of WASO, total sleep time , and sleep efficacy .

Why Is It So Hard To Sleep Now That I Have Parkinsons
Parkinsons can impact sleep in a number of ways, ranging from trouble falling or staying asleep at night to excessive sleepiness during the day. A good sleep boosts everything from your mood to your ability to think and process to your physical movement. Understanding sleep problems and Parkinsons is often the first step you can take to enhance your sleep.
In this post, we help you learn more about sleep problems in Parkinsons and how you can improve your quality of sleep.
Parkinsons can affect sleep in many different ways, including trouble falling or staying asleep, vivid dreams, waking up frequently during the night and excessive sleepiness during the day. Like other non-motor symptoms, sleep problems can appear before the more recognized motor symptoms, like tremor or stiffness.
People with Parkinsons typically experience some combination of insomnia and sleep fragmentation . Studies have shown people with Parkinsons have different sleep patterns and that their deepest periods of sleep during the night are shorter and interrupted more often than people without Parkinsons. Often this is made worse by medications that may wear off during the night, causing painful stiffness, difficulty moving in bed or other symptoms to return and disrupt sleep.
Diagnosis And Treatment Of Parkinsons Sleep Problems
Parkinsons disease is chronic and progressive, meaning it tends to get worse over time. However, there are treatment options that can help manage symptoms and allow patients to get more restful sleep.
The simplest way to start sleeping better with Parkinsons disease is by adopting healthy sleep habits. Sleep hygiene tips for Parkinsons disease sufferers include:
- Sticking to regular bedtimes
- Following a consistent bedtime routine with soothing activities such as listening to music or reading a calming book
- Getting regular exercise, preferably early in the day
- Getting adequate exposure to light, whether outdoors or through light therapy
- Avoiding long naps and naps late in the day
- Creating a cool, dark, and comfortable sleeping environment
- Restricting bedtime activities to sex and sleep only
- Turning off screens an hour before bedtime
- Reducing liquid intake before bedtime
- Avoiding caffeine, alcohol, and tobacco
- Eating a healthy diet and avoiding large meals at night
Light therapy, exercise, and deep brain stimulation have been successfully used to improve overall sleep quality and to treat specific conditions, such as REM sleep behavior disorder, in patients with Parkinsons disease. Cognitive behavioral therapy for insomnia has proven effective at reducing insomnia in healthy adults, although further research is needed on the effects of CBT in patients with Parkinsons disease.

Natural Course Of And Risk Factors For Eds In Pd
In a multicenter study, EDS was found in 165 of 436 PD patients, and logistic regression analysis revealed that male sex, Movement Disorder Society -sponsored revision of the Unified Parkinsons Disease Rating Scale III scores , hallucinations, and MDS-UPDRS II scores were associated with EDS . In the analysis by clinical subtype, ESS scores were significantly higher in the patients with the postural instability and gait disturbance type than in those with the tremor-dominant type. The prevalence of EDS increases after the onset of PD motor symptoms. In an 8-year follow-up study of 232 PD patients, the proportion of patients with EDS increased from 5.6%at the beginning of the study to 22.5%at 4 years and 40.8%at 8 years . Logistic regression analysis showed that factors contributing to EDS were older age, male sex, and dopamine agonist use, but in a subanalysis of the patients who were never treated with dopamine agonists, the predictor of EDS was Hoehn-Yahr stage alone. This result indicates that EDS is related to disease severity, independent of the effects of dopamine agonists.

How Are Sleep Problems Treated In People With Parkinsons Disease
Your provider will recommend treatments that address whats causing your sleeping challenges. Your provider may:
- Change your medication: If a medication could be causing your sleep issues, your provider may decide to adjust your treatment plan. Reducing the dose or switching medicines may solve the problem.
- Prescribe a new medication or therapy: If you have a sleep disorder, your provider will discuss your options. In some cases, your provider may recommend a new medication. If you have sleep apnea, wearing a special oral appliance can help. The device enables you to get a steady flow of oxygen, so your body doesnt gasp for air.
- Suggest lifestyle changes: Your daily habits and sleeping environment can help or hurt your sleep efforts. Setting regular sleep and wake times, keeping the room dark and avoiding electronic screens at bedtime may improve how well you sleep. If you have REM sleep disorder, your provider will discuss options for how best to protect you while you sleep.

Rapid Eye Movement Sleep Behavior Disorder
Rapid eye movement sleep behavior disorder is a parasomnia that arises out of REM sleep and leads to a loss of paralysis of skeletal muscles where patients may exhibit dream enactment behavior . These behaviors during sleep may range from mild muscle twitches to vocalizations to violent and complex motor behaviors. This can lead to falling out of bed, self-injury, or injury to bed partners . In fact, bed partners may be the first to note these types of complex behaviors during sleep, as patients themselves are unaware of most episodes . The prevalence of RBD is estimated to be 0.51% of the general population, but up to 50% in the PD population . A diagnosis of probable RBD can be made clinically based on the presence of nocturnal behaviors associated with vivid or violent dreams . A definitive diagnosis requires polysomnography confirmation of abnormal tonic elevation and/or bursts of muscle tone measured by electromyography , termed loss of REM atonia . The underlying mechanism leading to loss of REM atonia in PD is likely mediated by accumulation of alpha-synuclein in pontine nuclei such as the sublaterodorsal nucleus and ventral medial medulla, which send inhibitory projections to the spinal motor neurons during REM sleep . For a number of patients with PD, the symptoms of RBD precede motor manifestations and a formal diagnosis of PD by a median time of 10 years, providing an opportunity for early diagnosis and neuroprotective interventions .

Frequency Of Sleep Disorders And Other Nocturnal Features
Table 11 presents the prevalence of sleep disorders and other nocturnal features in patients with PD in 1993, 1997 and 2001. More than 50% of the patients reported insomnia at each study visit. The frequency of problems with sleep initiation and frequent awakenings varied from 23% to 30% and from 23% to 44%, respectively. In all, 1924% of the patients reported early morning awakening during the study period. Problems turning in bed, vivid dreaming or nightmares, and EDS were also common complaints, and their frequency increased significantly over time, whereas rapid eye movement sleep behaviour disorder suspect features varied in prevalence. The proportion of patients who had discussed the sleeping problem with their general practitioner increased over the years. The use of sleeping pills varied little. Other problems like pain or cramps, dystonia and myoclonic jerks during the night occurred in < 20% of patients, and their frequencies were rather stable during the study period. Among patients with insomnia, it was only in 1993 that the occurrence of problems turning in bed was more common than that related to insomnia .

The Best Sleep Aid For Parkinsons Patients
What are the best sleep aids for Parkinsons disease? clonazepam is a long-acting sedative that is most effective for Parkinsons patients in sleeping. Rather than immediately sedating, clonazepam aids in sleep regulation and makes sleeping easier. People suffering from Parkinsons disease and parkinsonism may notice an improvement in their symptoms if they take these medications. What medications can exacerbate Parkinsons disease symptoms? These medications include some of the most popular, such as Prochlorperazine , Promethazine , and Metoclopramide . They should be avoided in the first place. Furthermore, dopamine-depleted medications, such as reserpine and tetrabenazine, can worsen Parkinsons disease and parkinsonism and should be avoided at all costs. Do Parkinsons patients take zopiclone? In some cases, it may be preferable to use zopiclone , which is a better option depending on the type of sleep problem. Both of these medications are currently used to treat insomnia in Parkinsons patients without the disease. In some cases, the drug zopiclone may be more effective than other medications. Because of the side effects, such as drowsiness and dizziness, you should take it with caution.
Figuring Out Causes Of Fatigue
The first step in easing the fatigue associated with Parkinsons disease is to rule out other causes of tiredness, says Liana Rosenthal, M.D., assistant professor of neurology at the Johns Hopkins University School of Medicine and director of clinical core at the Morris K. Udall Center Parkinsons Disease Research Center of Excellence. We evaluate patients to see if there are other things contributing to the fatigue besides their disease, she says.
Sometimes patients may be referred to a sleep specialist for an evaluation. That can help identify causes of tiredness, like sleep apnea. Rosenthal says: Our aim is to first treat any sleep issues, like insomnia, sleep apnea or other causes of poor sleep. Once we treat and address those issues, we can see if fatigue still persists.

Limitations Of The Pdss
There are limitations of this scale like any subjective semiquantitative scale which attempts to provide a holistic and clinical assessment of the complex aetiology of sleep problems in Parkinsons disease.
First, we have not validated this instrument against a gold standard measurement of sleep architecture such as polysomnography. However, we feel that a complete validation of the PDSS is impossible, as several of the 15 items have no gold standards that could be validated polysomnographically. Our aim is to provide a simple, clinical, inexpensive bedside tool for semiquantitative evaluation of sleep problems in Parkinsonian syndromes.
Second, we are unable to comment on the confounding impact of concomitant medical conditions upon the PDSS scores obtained for individual items. The age matched controls, however, may have suffered from a similar amount of concomitant disorders. It would be necessary to control for depression, psychosis, and other disorders such as arthritis that may have a confounding influence on sleep in future studies.
Insomnia And Parkinsons Disease
Parkinsons disease comes with its fair share of challenges. Among the most frustrating symptoms of Parkinsons is insomnia, or difficulty sleeping. Research has found that the majority of people with PD experience trouble sleeping, and more than 3,000 members of MyParkinsonsTeam report difficulty sleeping as a symptom. Lack of regular sleep can have tremendous impacts on a persons quality of life. In fact, dealing with a sleep deficit can cause anyone to experience problems with memory and thinking.
Good, restful sleep is vital for people with Parkinsons, but it isnt always easy to get quality sleep. Luckily, there are some ways you can work toward combating insomnia with Parkinsons.

Falling Asleep During The Day
Not getting enough restful sleep at night, some medications, and possibly the disease itself leading to neurodegeneration can lead to daytime sleepiness and even sleep attacks in people with Parkinsons disease.
Excessive daytime sleepiness is one of the most frequent sleep disorder symptoms in Parkinsons disease and can affect a patients quality of life.
Trying to get more restful sleep at night and adjusting medications can help with excessive daytime sleepiness.
A new therapy from Theranexus is also currently being investigated in a Phase 2 clinical trial to help with excessive daytime sleepiness.

Diagnosis Of Excessive Daytime Sleepiness In Pd
In patients describing the symptoms of EDS, it is very important to determine the level of sleepiness. The Epworth Sleepiness Scale is widely used in the evaluation of EDS. Thus, ESS is a useful scale for the subjective assessment of sleepiness in patients with EDS .The ESS contains eight items, and each item is rated as maximum three points. A higher score means more sleepiness level. In addition, there are objective tests such as multiple sleep latency test and maintenance of wakefulness test for assessment EDS. The MWT is evaluation used as a polysomnographic measurement of EDS. The MSLT is measured after a PSG performed in the night to assess nighttime sleep quality and quantity . One study found that the risk of traffic accidents increased in PD patients with an ESS score greater than 7 .
