Medication
As a result of advances in experimental therapeutics, many promising therapies for PD are emerging. Levodopa remains the most potent drug for controlling PD symptoms, yet is associated with significant complications such as the “wearing off” effect, levodopa-induced dyskinesias and other motor complications.
Procedures
Drooling (sialorrhea), one of the most embarrassing symptoms of PD caused by impaired swallowing, has been successfully treated with botulinum toxin injections (Bhatia et al 1999; Pal et al 1999; Sheffield and Jankovic 2007). The most important principle in the management of PD is to individualize therapy and to target the most disabling symptoms.

How many new medications have been approved for Parkinson's?
Remarkably, in the last five years, seven new medications have been approved for the treatment of the motor symptoms of Parkinson’s disease (PD), with two approved in 2020. That’s exciting progress! And while it is great to have so many choices, the various options can be confusing — so today I will describe these new medications and their uses.
Can Parkinson's disease be managed?
With multiple new medications available for the treatment of PD, there is more hope than ever that Parkinson’s symptoms can be successfully managed for many years. A few things to consider:
Do newly approved medications have the same mechanism of action as older medications?
On the other hand, many of the newly-approved medications have the same mechanisms of action as older medications (that is, they are very similar drugs to ones already available) so they are not breaking new ground in treating symptoms.
Is opicapone a comt inhibitor?
Opicapone (Ongentys ®) is a cate chol-O-methyltransferase (COMT) inhibitor that is taken once a day. It was approved in the US in 2020 as an add-on therapy to levodopa for motor fluctuations.
Is PD a challenge?
Despite the new treatments discussed above, PD presents significant challenges for many people, especially as the disease advances. Research focused on improvement of motor and non-motor symptoms continues. In addition, discovering treatments that will slow down or halt disease progression is a major emphasis of current PD research, with the hope that soon medications will not only be available to treat symptoms, but to improve the course of PD.
Is amantadine ER approved?
It is designed to provide an initial lag, followed by a slow rise in amantadine concentration during the night, and a high concentration in the morning and through the waking day. In 2018, a second extended-release formulation of amantadine (Osmolex ER ™) was approved. It is taken once daily in the morning and is indicated for the treatment of PD motor symptoms as well as drug-induced parkinsonism.

How to help Parkinson's patients with Parkinson's disease?
This includes maintaining a healthy diet, exercising regularly, and getting plenty of sleep. Tai chi and yoga have both proven to encourage better balance and coordination for people with Parkinson’s disease. Alternative therapies include massage, acupuncture, and taking supplements that are good for your brain, like CoQ10.
How do you know you have Parkinson’s disease?
There is no definitive way to diagnose Parkinson’s disease. Your doctor will ask questions about the onset of your symptoms and assess your movement to make referrals to specialists who can make a formal diagnosis.
How to improve quality of life with Parkinson's disease?
Talk to your doctor about your specific symptoms and how they are impacting your day-to-day life. Together, you can develop a plan for improving your quality of life with Parkinson’s disease. With early detection and a robust treatment plan, it is possible to alleviate and slow down the onset of symptoms.
How old do you have to be to get Parkinson's?
While anyone can develop Parkinson’s disease, age is the greatest factor in receiving a diagnosis. The average age of developing this disease is 60, and men are more likely to receive a diagnosis than women. Having a close relative, like a parent or sibling, who has Parkinson’s disease doubles your risk factor.
How many cases of Parkinson's come from genetics?
Scientists who have studied this disorder estimate that 10-15% of cases come from genetics after seeing a series of genetic mutations that were common in Parkinson’s patients. Doctors suspect that environmental factors and lifestyle choices may have effects on the severity of Parkinson’s disease symptoms.

You may also try exercises such as walking, swimming, gardening, dancing, water aerobics or stretching. Parkinson's disease can disturb your sense of balance, making it difficult to walk with a normal gait. Exercise may improve your balance. These suggestions may also help: Try not to move too quickly.
What is the best treatment for Parkinson's disease?
Levodopa remains the most potent drug for controlling PD symptoms, yet is associated with significant complications such as the “wearing off” effect, levodopa-induced dyskinesias and other motor complications. Catechol-o-methyl-transferase inhibitors, dopamine agonists and nondopaminergic therapy are alternative modalities in the management of PD and may be used concomitantly with levodopa or one another. The neurosurgical treatment, focusing on deep brain stimulation, is reviewed briefly. Although this review has attempted to highlight the most recent advances in the treatment of PD, it is important to note that new treatments are not necessarily better than the established conventional therapy and that the treatment options must be individualized and tailored to the needs of each individual patient.
How to treat levodopa dyskinesia?
There are three strategies designed to improve levodopa-induced dyskinesias: 1) reduce the dosage of levodopa, 2) use drugs known to ameliorate dyskinesias, and 3) surgery. Several drugs, including amantadine, have been reported to improve levodopa-induced dyskinesias without necessitating the reduction in levodopa dosage (Verhagen Metman et al 1999). The addition of a COMT inhibitor, MAO-I inhibitor or a dopamine agonist inhibitor may be used in the management of levodopa-induced motor complications (Jankovic et al 2007) (Table 2). Other drugs with antidyskinetic effect include clozapine, fluoxetine, propranolol, the cannabinoid receptor agonist nabilone, and fipamezole. Some of the new antiepileptic drugs are being investigated as potential therapies for levodopa-induced dyskinesias. For example, levetiracetam (Keppra®) was found to significantly reduce levodopa-induced dyskinesias in MPTP-lesioned marmosets (Hill et al 2003). In patients with severe motor fluctuations, apomorphine, a subcutaneous dopamine agonist, may be used as rescue therapy (Pietz et al 1998).
How does levodopa help with motor fluctuations?
Strategies designed to prolong and smooth out the therapeutic concentrations of levodopa- related motor fluctuations usually improve by increasing the frequency of administration of levodopa. Slow-release preparations of levodopa, such as Sinemet®CR, offer the possibility of “smoothing out” clinical fluctuations by slowly releasing the levodopa from a special matrix. In addition to prolonging the “on” time, smoothing out the wearing off response and reducing the total number of doses and tablets taken per day, Sinemet CR also seems helpful in alleviating troublesome nighttime rigidity, thus allowing patients to have more restful nights and better nighttime mobility. Potential disadvantages of Sinemet CR over standard preparations include delayed or poor response after the morning dose (absence of the “morning kick”) and an exacerbation and prolongation of peak-dose dyskinesias.
What is the most important principle in the management of PD?
The most important principle in the management of PD is to individualize therapy and to target the most disabling symptoms. The selected therapy should be based on scientific rationale and designed not only to control symptoms, but also to slow the progression of the disease (Figure 2). Since younger patients are likely to require dopaminergic therapy for longer time and are at increased risk for the development of levodopa complications, levodopa sparing strategies, such as the use of MAO inhibitors and DA agonists, are even more critical in this population (Jankovic 2000). Certain symptoms of PD, such as dysarthria, dysphagia, freezing and other “axial” symptoms, usually do not respond to dopaminergic therapy and may be mediated by nondopaminergic systems (Bonnet 2000; Kompoliti et al 2000). It is very likely that with better understanding of the mechanisms of neurodegeneration, novel and more effective therapeutic strategies will be available in the near future.
Is levodopa effective for Parkinson's disease?
Although levodopa is clearly the most effective drug for the treatment of motor symptoms of PD, whether levodopa should be used in early stages of PD or delayed until later in the disease process has been the subject of many debates. This debate is partly fueled by the observation that in patients with early onset PD (particularly before the age of 40), their disease course is longer and they have a particularly high risk for developing motor fluctuations and dyskinesias. The argument to delay levodopa therapy is chiefly supported by studies showing that early use of dopamine agonists delays the need for levodopa and thus delays the onset of levodopa-related motor complications, particularly motor fluctuations and dyskinesias, and that dopamine agonists may exert favorable disease-modifying effects (Le and Jankovic 2001; Parkinson Study Group 2002; Simpkins and Jankovic 2003; Whone et al 2003). The strategy of early initiation of levodopa is supported by studies that indicate that levodopa provides a longer period of superior motor control, slower progression of disability, longer life expectancy (Lees et al 2001; Rajput et al 2002), and no difference in “clinically relevant” dyskinesias between levodopa and dopamine agonist treated patients (Lees et al 2001). There is a lower incidence of hallucinations, vomiting, and leg edema with levodopa as compared to dopamine agonists (Whone et al 2003), and no in vivo evidence of levodopa toxicity (Le and Jankovic 2001). Since younger patients seem to be at a higher risk of levodopa-related motor complications, delaying levodopa therapy seems to be a prudent practice at least in this population of PD patients.
Does Comt cause dyskinesia?
While this pharmacologic action of the COMT inhibitors may prolong the “on” time without markedly increasing dyskinesias, most studies do report increased levodopa-induced dyskinesia in patients taking COMT inhibitors, requiring a substantial (>25%) reduction in daily levodopa dosage.
Can DBS be used for levodopa?
Consider surgery (DBS) in patients who are levodopa-responsive but their levodopa-related motor complications cannot be managed adequately with medication adjustments
What is the best treatment for PD?
The greatest breakthrough in medical treatment for PD so far in our lifetime is the use of L-dopa for treating the symptoms of PD and Gerald was the first neurologist in the UK to administer L-dopa to PD patients, and to establish the first dedicated PD clinic in the country. Gerald was also on the forefront of many other significant therapeutic advances that have improved the lives of those with PD, notably the use of MAO inhibitors (Elsworth et al. 1978; Lees et al. 1977) and directly-acting dopamine (DA) agonists (Stibe et al. 1988). While these successes are well known, it is some of his lesser known studies that illustrate his creativity and drive to alleviate the plight his patients. While doubtless some ventures were never formally reported, the breadth of those that did are illustrative, including studies with PD patients on the effect of amantadine (Hunter et al. 1970), metatyrosine (Sandler et al. 1972), melatonin (Shaw et al. 1973), thyrotrophin-releasing hormone (McCaul et al. 1974), lithium (McCaul and Stern 1974), baclofen (Lees et al. 1978), electroconvulsive shock therapy (Ward et al. 1980), vitamin E (Stern 1987), and marijuana (Frankel et al. 1990). Further review of his writings also reveals an early appreciation of the potential value of computerized tracking of patients’ symptoms (Cassell et al. 1973) and a prescient investigation of nasal administration of therapeutics (Kleedorfer et al. 1991). Early in his career, Gerald held a research appointment under the direction of Dr Mettler at Columbia University, and during this time he was involved in brain lesion studies to advance understanding of the regions involved in generating parkinsonian signs, and interestingly these studies included the subthalamic nucleus (Stern 1966). This experience doubtless influenced his view that surgery had a valuable place in PD treatment (Stern 1969). Since that time of course the subthalamic nucleus has become a major target for DBS in the treatment of parkinsonian motor symptoms (Bronstein et al. 2011; Faggiani and Benazzouz 2017).
What is progress in Parkinson's disease research?
Progress in PD research will rely on the use of appropriate testing models. With animal models, the choice of species employed is a critical factor, as illustrated by well-known example of primate susceptibility to MPTP compared with rodents (Chiueh et al. 1984). A lesser known example was provided with quintessential wit by Gerald (Stern 2012b), where he describes the unique sensitivity of horses to develop nigropallidal necrosis following consumption of the plant, yellow star thistle! Newer approaches to modelling include the ex vivo study of patient-derived induced-pluripotent stem cells and three-dimensional organoid-based culture systems, which permit further insight into Parkinson’s disease pathogenesis and potential therapeutic targets (Grenier et al. 2020; Marotta et al. 2020). In vivo modeling has also advanced, now allowing the creation of transgenic animals, including nonhuman primates (Chen et al. 2019; Scaduto 2016), although this is challenging for diseases that stem from multiple genetic loci containing risk variants. Theoretically at least there is the specter of interspecies chimeras from closely related species, such as those between humans and other primates in order to model CNS diseases with complex genetic contributions, using interspecies blastocyst complementation (De Los Angeles et al. 2019); I wonder what Gerald would have thought of that!
What is pioglitazone used for?
2011), although little is known about the precise molecular mechanisms that lead to these neuroprotective effects. We have recently found that pioglitazone administration activates expression in brain of an interesting, but little-studied, mitochondrial enzyme, paraoxonase-2 (PON2) (Blackburn et al. 2020). Located on the inner mitochondrial membrane, PON2 enhances the function of coenzyme Q in the electron transport chain and subsequently reduces the production of reactive oxygen species that can lead to oxidative stress (Devarajan et al. 2011). PON2 is most highly expressed in dopamine-rich regions of brain (Costa et al. 2014) and PON2 deficiency hypersensitizes neurons to oxidative stress induced by 1-methy1–4-phenylpyridinium (MPP+), the toxin generated in vivo following MPTP delivery (Parsanejad et al. 2014). Interestingly, in rodents and primates PON2 expression peaks during development and has fallen by adulthood (Garrick et al. 2016), which coincides with age-related susceptibility of dopamine neurons to the parkinsonian protoxin, MPTP and to methamphetamine in primates (Morrow et al. 2011; Morrow et al. 2012).
What is Gerald Stern's contribution to Parkinson's disease?
The substantial contributions of Dr Gerald Stern to past and current treatments for Parkinson’s disease patients is reviewed , which form the foundation for an evaluation of future options to control symptoms and halt progression of the disease. These opportunities will depend on a greater understanding of the relative contributions of the environment, genetic and epigenetic influences to disease onset, and promise to emerge as strategies for improving mitochondrial function, halting synuclein and neuromelanin accumulation, in addition to refinement of stem cell and gene therapies. Such advances will be achieved through deployment of improved models for the disease.
What are the causes of PD?
Certainly there are identified toxins that can induce PD or PD-like conditions, such as viral encephalitis, exposure to high level of certain metals or particular pesticides/herbicides/fungicides (Chen and Ritz 2018). But encountering such risk factors alone is not enough to account for the development of all idiopathic cases PD. However, polymorphisms in genes not directly associated with PD could translate to differential susceptibility to toxins and blur the distinction between idiopathic and familial forms of PD. Particular attention has focused on the cytochrome P450 enzyme, CYP2D6, which is highly expressed in the liver and certain areas of the central nervous system, particularly the substantia nigra. CYP2D6 is one of the most important enzymes involved in the metabolism of xenobiotics in the body and plays a role in metabolism of approximately 25% of clinically used drugs. The CYP2D6 gene codes for several splice variants and protein products with different catalytic activity. So-called “poor metabolizers”, will incur greater impact than other individuals from environmental toxins that rely on CYP2D6 for metabolism and it is relevant therefore that “poor metabolizers” have an increased risk of developing PD (Ur Rasheed et al. 2017). This is just one example of an interaction between genetics and environment relevant to induction of PD.
Is pioglitazone safe for PD?
Pioglitazone has had mixed outcomes in clinical studies with PD patients (Brakedal et al. 2017; Investigators 2015; Wu et al. 2018), although it should be noted that the lack of a detectable effect in negative studies could be due to the relatively low dose of pioglitazone employed, compared with preclinical studies, and/or the short duration of pioglitazone treatment. In addition, the loss of nigrostriatal DA neurons in particular patient populations may have been too great for a protective effect to be discerned. Thus, it may be too soon to dismiss the potential benefits that glitazone drugs offer in PD, especially in patients with type 2 diabetes or dementia (Lu et al. 2018; Tseng 2018). We suspect that the pioglitazone-induce increase in expression of PON2 in striatum likely contributes to the neuroprotective effects of the drug observed in preclinical models of PD, ischemia and stroke (Cai et al. 2018). We hope that our new data stimulate research into other pharmacological tools to activate PON2 expression in brain and achieve neuroprotection. Stimulation of central PON2 expression in adults promises to be successful and well-tolerated as it relies on reinstating the relatively high levels that occurred during development.
