Melatonin And The Circadian System
Disruptions to our circadian rhythms can leave us feeling fatigued, irritable, and out of sorts. If youve experienced jet lag, you know the feeling. Fortunately, it passes once you adjust.
This adjustment occurs, in part, due to adaptations by the pineal gland in the brain, which releases the hormone melatonin. Melatonin may be best known for regulating sleep, but it plays a larger role in overall health.
It works across body systems to support major functions. For instance, melatonin provides guidance in the timing of digestion.
Melatonin, then, is a workhorse for the circadian system. For this reason, researchers always look at its levels to uncover clues to disruptions of the body clock.
Here Are Some Sleep Hygiene Tips:
- Be mindful of what you eat for dinner. High-protein foods may interfere with the absorption of medications for Parkinsons . This may make the medication wear off prematurely, causing symptoms to return in the night.
- High-protein foods, particularly meat and dairy, also take longer to digest. This could lead to reflux and other issues that could interfere with sleep.
- Reduce liquids a couple of hours before bed to try to reduce the number of times you need to get up in the night to use the toilet.
- Although regular exercise is associated with better sleep quality, its important to avoid strenuous activity too late in the evening as it may increase alertness and interfere with sleep.
- Avoid sources of blue light.
- Computers, tablets, smartphones and televisions emit light in the same spectrum associated with daylight . Spending time with these blue-light sources in the evening can sometimes fool your sensory system, tricking the brain into thinking that it is daytime and making it harder to fall asleep.

The Role Of Melatonin In Parkinsons Disease
Melatonin is commonly known for its ability to treat insomnia. However, recent research shows that it also has the potential to treat the symptoms of Parkinsons disease. Many clinical studies have highlighted the role of melatonin in Parkinsons disease and displayed it as one of the alternative therapies for Parkinsons patients.
Why Do The Study
Melatonin is used to help sleep, but this scientific study will determine whether there is a true effect in individual people with Parkinsons Disease. By recording individual symptoms in a sleep diary and using a special watch to record sleep patterns, we will be able to identify individual responders and non-responders to melatonin. This will have positive impacts on health and quality of life for both people with Parkinsons Disease and their family members .

Causes Not Related To Parkinsons
There are a number of other causes of sleep problems that are not related to Parkinsons, such as pain not connected to Parkinsons or sleep apnea. People with sleep apnea experience frequent interruptions in their breathing as they sleep, which can further fragment sleep and cause low levels of oxygen in the blood.
Finally, simply failing to prepare the bedroom for rest by minimizing outside light and activities as well as reducing noise can have a major impact on sleep quality. Exercising too late in the afternoon or evening can sometimes make it difficult to fall asleep. Similarly, drinking too many liquids, especially alcohol or caffeine, can interfere with sleep at night.
What Else Can I Do To Sleep Better With Parkinsons Disease
Practicing healthy sleep hygiene habits may also promote more restful sleep.
- Get outside during the day. Bright light tells your body its time to be awake.
- Keep your body moving during the day. Even if all you feel up to is a short walk or two, all physical activity offers benefits.
- Try at-home remedies, such as massage or a warm bath. Relaxing your mind may help your body fall asleep.
Dont:
- Take long naps during the day.
- Use stimulants, such as caffeine, within six hours of bedtime.
- Use your bedroom for activities other than sleeping. Go to another room to read, watch TV or work.

Ror Expression Was Down
To investigate whether ROR was involved in the inflammation process of PD, we first studied the biological role of ROR in BV2 cell line treated with different concentrations of 1 methyl 4 phenyl pyridinium ion . Cell viability was measured and CCK-8 results showed the toxic effects. The results showed 2530% of decrease in BV2 cell viability induced by 50µM MPP+ . Both real-time quantitative polymerase chain reaction and western blotting analyses showed that the expressions of ROR in MPP+- treated BV2 cells increased at low doses of MPP+ but significantly reduced at the high dose 50M . We also observed that pro-inflammatory factors gradually increased, along with the decreased anti-inflammatory factors like IL-10 as the concentration of MPP+ increased . The altered ROR expression combined with altered levels of cytokines suggested that ROR be an anti-inflammation player in PD.
Fig. 1: The level of ROR was reduced in BV2s treated with MPP+.
BV2 cells were treated in different concentrations of MPP+ for 24h. a Relative mRNA levels of ROR were measured by RT-qPCR. b, c Immunoblot analysis of ROR. Protein expression levels were normalized to GAPDH. d ELISA assays showed the levels of IL-6, TNF-, IL-1, and IL-10 in culture medium. Data were average with error bars representing standard deviation. .
A Summary Of The Most Recent Evidence
A number of review articles discussing the use of melatonin in PD and other neurodegenerative conditions have been published since 2015 , , -, – some were written prior to the publication of the most recent RCTs, and their results/recommendations should be interpreted with this caveat.
The most up-to-date recommendations available come from the French Medicine and Research Sleep Society expert group consensus , which concluded that:
iven the good tolerance/efficacy profile of MEL, in these fragile populations, we believed that MEL should be tried as a first step in RBD treatment Complementary studies are required before recommending MEL in PD sleep disorders without RBD. However, given the good tolerance profile of MEL in these fragile populations, melatonin may be tried as a treatment.
A UK review article on RBD published in 2020 concluded that clonazepam is probably more efficacious than melatonin, noting that both cause side-effects including morning or daytime drowsiness, nocturnal confusion and falls, so should be used with caution and following specialist review. Recent reviews specifically addressing RBD in PD populations have recommended that clonazepam or melatonin be considered as treatment options , , 2017 NICE guidance similarly recommends using either to treat RBD in PD.

Other Potential Benefits Of Melatonin In Parkinsons Patients
The beneficial effects of melatonin are not limited to sleep only. Researchers think its intake may also improve other complications associated with Parkinsons, including both motor and non-motor.
But research in this regard is still in the preliminary stage, and therefore large numbers of control clinical trials are needed to fully establish its therapeutic effects on other symptoms besides sleep.
Why Do Parkinsons Patients Have Trouble Sleeping
Despite having daytime tremors, Parkinsons patients do not shake in their sleep. However, both Parkinsons disease itself and the medications used to treat it can give rise to a number of sleep problems that lead to insomnia and excessive daytime sleepiness.
Patients with motor symptoms may have trouble adjusting sleeping positions to get comfortable. Others may experience distressing nocturnal hallucinations when trying to fall asleep. These may be a result of medications or cognitive impairment.
In turn, excessive daytime sleepiness may occur as a consequence of sleeping poorly at night. It may also be triggered by medications. Parkinsons patients who suffer from EDS may be at a higher risk of accidents and unable to safely carry out activities such as operating a motor vehicle.
Since insomnia frequently goes hand-in-hand with anxiety and depression, it may be a contributing factor to sleep problems in people with Parkinsons disease. For that reason, doctors often look for mental health disorders in people with Parkinsons disease who have sleep problems.

What About Its Beneficial Effects In Patients
There have been conducted some clinical trials where the beneficial effects of melatonin were tested in Parkinsons patients. Most of the results obtained as yet indicate that it is useful in improving the sleep quality in patients.
A study involving 40 patients with Parkinsons showed that 5 mg of melatonin improved the overall sleep disturbance when used for 2 weeks. In the same study, melatonin concentration of up to 50 mg was shown to be well tolerated.
In another study, the efficacy of melatonin was compared with a widely used sleeping drug clonazepam in 38 patients with Parkinsons. The patients were given either 3 mg melatonin or 2 mg clonazepam at night for 6 weeks. Both drugs were able to reduce sleep disorders in their respective group. However, the clonazepam using patients showed daytime sleepiness, which was absent in the melatonin-treated group. In this study, the melatonin treatment also improved neuropsychological performance, which was assessed by the Mini-Mental state examination.
It is still uncertain whether it can treat other symptoms of the disease. The research in this regard is still in the preliminary stage and its too early to suggest its beneficial effects beyond sleep.
How About For Parkinsons
Over the past few years, researchers have been trying to find the role of melatonin in Parkinsons disease. The evidence collected so far indicates that there is a possible involvement of melatonin in the disease process.
In a post-mortem study of the brains from patients with Parkinsons, it was found that the number of melatonin receptors was significantly decreased when it was compared with brains from control subjects. This decrease was found particularly in regions that are linked to Parkinsons.
There is also evidence indicating that melatonin works closely with dopamine. Dopamine is a well-known neurotransmitter that is produced by a special group of cells located in the brain area called the substantia nigra, a Latin word for black substance. When the brain failed to produce a sufficient amount of dopamine, the body develops symptoms of Parkinsons disease.
Melatonin is frequently found in close proximity to dopamine in the substantial nigra part of the brain. Together, they work in a chemical opposition meaning they oppose each other activity according to the situation. For example, in the daytime, the level of melatonin is low and dopamine is high. While in the night, the dopamine level is down and melatonin is elevated.
Researchers think that it could be a disturbance in the balance between the two chemicals that contribute to Parkinsons disease changes in the brain.

Inclusion And Exclusion Criteria
The inclusion criteria were as follows: Study type: randomized controlled trials Participants: patients who were clinically diagnosed with PD Interventions: the experimental group was given melatonin or prolonged-release melatonin Control: the control group was given placebo or clonazepam and Outcome: at least one of the following 4 instruments was employed: Pittsburgh Sleep Quality Index , Epworth Sleepiness Scale , RBD questionnaire and polysomnography sleep parameters.
Exclusion criteria were: Non-randomized controlled trial Repeated publication and Studies whose outcomes did not meet our meta-analysis requirements.
Evidence For Safety And Tolerability
The evidence for the safety and tolerability of melatonin is more compelling than that for its efficacy. Gilat et al. found that adverse effects were mild , while in Ahn et al’s study no participants reported adverse effects. Previous clinical trials in PD patients have also found that melatonin is well tolerated,, with little impact upon daytime sleepiness despite improved subjective sleep quality.
Research in non-PD populations has also demonstrated a promising side-effect profile. In a study using healthy volunteers, there was no statistically significant difference between melatonin and placebo groups in reported side-effects. Two meta-analyses one examining melatonin use in primary sleep disorders , and the other in secondary sleep disorders found that the most commonly reported adverse effects were nausea, headache, dizziness and drowsiness, but there were no significant differences between placebo and melatonin groups in any of the included trials in either meta-analysis., Both analyses noted that the safety of exogenous melatonin when used in the long term remains unclear.
Research directly comparing the tolerability of clonazepam versus melatonin is limited. McCarter et al. found that patients treated with clonazepam reported more frequent side-effects than those treated with melatonin. There are no RCTs directly comparing melatonin versus clonazepam tolerability in PD or RBD populations.

Neuroprotective Agents For Parkinsons Disease
Relevant preclinical studies have identified several compounds such as MLT, estrogen, nicotine, caffeine, riluzole, curcumin, aspirin, epigallocatechin-3-gallate and resveratrol, as neuroprotective agents in PD . Various prospective studies have suggested a strong association between tobacco smoking and a decreased risk of PD. Nicotine is one of the main constituents of tobacco and is known for its pharmacological effects, exerted by interaction with cholinergic nicotinic receptors in both central and peripheral nervous systems . A recent clinical trial among six male PD patients demonstrated that chronic high doses of nicotine improved motor scores, reduced dopaminergic treatment and had a potential beneficial effect on striatal dopamine transporter density . Chronic nicotine treatment partly protects against the MPTP-induced degeneration of nigrostriatal dopamine neurons in the black mouse, counteracts the disappearance of tyrosine-hydroxylase-immunoreactive nerve cell bodies, dendrites and terminals in the mesostriatal dopamine system and prevent striatal dopamine loss provoked by 6-OHDA administration in the substantia nigra .
Figure 2.
MLT seems to function via a number of means to reduce oxidative stress. It can develop its action at two levels: as a direct antioxidant, due its ability to act as a free radical scavenger, and as an indirect antioxidant, since it is able to induce the expression and/or the activity of the main antioxidant enzymes.

Medical Specialists Can Help Prioritize Sleep
If you have PD, you likely have a complicated relationship with melatonin and should probably avoid taking this over-the-counter therapy if you cant sleep at night.
Instead, if you struggle to get good quality sleep or encounter periods of intense sleepiness during the day, its a good idea to talk about these problems with your specialist. They can help you find better sleep through medications or non-drug alternatives. Suggestions for improved sleep hygiene also support easy, low-cost ways to prioritize sleep.
Finally, they might refer you to the services of a CBT-i practitioner.4 This medical professional specializes in cognitive behavioral therapy for insomnia. CBT-i can help people with PD learn ways to reset their circadian systems to make way for more and better sleep.5
The therapy is widely available in telehealth applications which allow you to safely participate from the comfort of your own home.

Mitochondrial Dysfunction In Parkinsons Disease And The Neuroprotective Effects Of Melatonin
PD is a neurodegenerative disorder of multifactorial etiology. Among the several putative causal factors, oxidative stress and inflammation have been claimed to play a role in the loss of dopaminergic neurons . The principal mediators of inflammatory responses in PD are the microglial cells which upon activation release inflammatory cytokines and reactive oxygen species . In addition, a dysfunctional bloodbrain barrier also appears to be involved in the progression of the disease .
The MPTP model of PD is a valuable tool for studying not only the participation of various factors such as oxidative/nitrosative stress, excitotoxicity, and inflammation in the pathogenesis of PD, but also for studying the role of mitochondrial dysfunction. MPTP is metabolized into MPP+ which is taken up into the dopaminergic neurons through dopamine transporter and accumulates in the mitochondria of SN . MPP+ binds to Complex I of the electron transport chain to inhibit it, thereby causing increased generation of reactive oxygen species. This results in oxidative damage to ETC, decreased ATP production and nigral cell death . MPP+, by inducing microglial activation and iNOS expression in SN, has been shown to produce large amounts of NO and to cause neuronal cell death . NO, by reacting with O2- generates the highly toxic peroxynitrite, an agent that impairs mitochondrial function and causes irreversible inhibition of all ETC complexes and neuronal cell death .

Can Melatonin Treat Other Symptoms Of Parkinsons Disease
People with Parkinsons disease who take melatonin tend to have fewer symptoms of less severity than those who do not take it. For a long time, this was attributed to the restorative nature of adequate sleep. However, we now know that melatonin is not only a sleep-inducing hormone but a neuroprotective one as well. Although it is still being researched, melatonins neuroprotective qualities are believed to actually slow the progression of PD, delaying the neurological damage that causes the progressive loss of neuromuscular function.
The circadian rhythm, or the bodys roughly 24-hour cycle, is also an important factor to consider in the timing of administration of other medications taken by people with PD. COMT inhibitors, for example, are a common drug class used to treat Parkinsons disease. These absorb in far higher levels when taken in the morning, thus offering more therapeutic effect. Because the treatment of PD is complicated, it is important to take drugs at times when they will be most effective.
Studies in the field of chronobiology are offering new treatments for some of mankinds most difficult diseases. People with Parkinsons disease may soon get the sleep they need to function as well as more effective treatments due to a better understanding of this diseases effects on the circadian rhythm.
