Understanding Parkinson’s Disease and Latest Developments in Treatment and Prevention

Parkinson’s Disease Overview

Parkinson’s disease (PD) is a complex neurological disorder that affects millions of people worldwide. It is characterized by a range of symptoms, including slow movements, tremors, rigidity, and balance issues. Over time, PD can lead to severe disability and have a significant impact on an individual’s quality of life. While there is currently no cure for PD, various therapies and medications can help manage its symptoms.

Signs and Symptoms of Parkinson’s Disease

The symptoms of Parkinson’s disease often worsen with time and can greatly affect an individual’s well-being and quality of life. Motor symptoms of PD include slow movement, tremors, involuntary movements, rigidity, trouble walking, and balance problems. In addition to motor symptoms, non-motor symptoms such as cognitive impairment, mental health disorders, dementia, sleep disturbances, pain, and sensory disturbances can further complicate the lives of individuals with PD.

Assessment and Disease Burden

PD is typically diagnosed by neurologists, but it can also be diagnosed by trained non-specialized healthcare workers. This is especially crucial in regions where specialized neurological services are limited. The prevalence of PD has been on the rise, with over 8.5 million individuals affected globally. In 2019 alone, PD resulted in 5.8 million disability-adjusted life years (DALYs) and caused 329,000 deaths.

There are several different types of Parkinson’s disease, each with its own distinct characteristics. These types include:

  1. Idiopathic Parkinson’s Disease (PD):
    • This is the most common form of Parkinson’s disease.
    • It has no known specific cause and typically occurs sporadically.
    • Symptoms may include tremors, bradykinesia (slowness of movement), rigidity, and postural instability.
  2. Young-Onset Parkinson’s Disease:
    • Also known as early-onset or juvenile-onset Parkinson’s, this form occurs in individuals under the age of 40.
    • The symptoms are similar to those of idiopathic Parkinson’s disease, but it affects younger individuals.
  3. Parkinson’s Plus Syndromes:
    • These are a group of related disorders that share some symptoms with Parkinson’s disease but also have additional distinct features.
    • Examples include Multiple System Atrophy (MSA), Progressive Supranuclear Palsy (PSP), and Corticobasal Degeneration (CBD).
    • These conditions tend to progress more rapidly and may not respond as well to typical Parkinson’s medications.
  4. Drug-Induced Parkinsonism:
    • Some medications, particularly antipsychotic drugs and certain anti-nausea medications, can cause parkinsonian symptoms as a side effect.
    • The symptoms often improve or resolve once the medication is discontinued.
  5. Vascular Parkinsonism:
    • This type of parkinsonism is linked to problems with blood flow in the brain, typically due to small strokes.
    • Symptoms may resemble Parkinson’s disease but tend to progress more slowly.
  6. Secondary Parkinsonism:
    • This results from other medical conditions, such as head injuries, encephalitis, or Wilson’s disease, that damage the brain’s basal ganglia.
    • Treating the underlying condition may improve parkinsonian symptoms.

It’s essential to consult a healthcare professional for an accurate diagnosis and appropriate management, as the treatment and progression of these different types of Parkinson’s disease can vary significantly.

Treatment and Care

While there is no cure for Parkinson’s disease, various therapies and medications can help manage its symptoms. Levodopa/carbidopa, a combination medication that increases dopamine levels in the brain, is commonly prescribed to individuals with PD. Other medications, such as anticholinergics, may be used to reduce involuntary muscle movements.

Surgical interventions, such as deep brain stimulation, can help alleviate tremors and reduce the need for medications. Additionally, rehabilitation, including physiotherapy, offers relief to individuals with PD. These therapies include strength training, gait and balance training, and hydrotherapy, which can significantly improve functioning and quality of life.

However, it’s essential to note that many medications and surgical resources may not be readily accessible, available, or affordable in low- and middle-income countries, highlighting the need for improved access to treatment worldwide.

Impact on Families and Carers

The impact of Parkinson’s disease extends beyond individuals with the condition; it also affects their families and carers. Informal carers, often family members and friends, dedicate numerous hours each day to providing care. This role can be overwhelming, leading to physical, emotional, and financial stress. Support from various systems, including health, social, financial, and legal services, is crucial for families and carers. Drawing upon support resources from other conditions, such as the WHO’s iSupport program for dementia, can provide valuable assistance.

Human Rights and Stigma

People with PD often face stigma and discrimination, both within the workplace and in their communities. To ensure their rights are upheld, individuals with PD require accessible health services, access to medication, and support in line with general healthcare needs. Overcoming barriers, such as healthcare providers’ inadequate knowledge and misconceptions that PD is contagious or a normal part of aging, is essential in promoting inclusion and eliminating discrimination.

WHO Response and Global Action Plan

The World Health Organization (WHO) has taken significant steps to address the challenges posed by PD and other neurological disorders. The Intersectoral Global Action Plan on Epilepsy and Other Neurological Disorders 2022–2031, endorsed by the World Health Assembly, aims to provide a comprehensive response to these conditions. It focuses on raising policy prioritization, strengthening governance, improving diagnosis, treatment, care, promoting prevention, fostering research and innovation, and enhancing information systems.

WHO has also developed a technical brief titled “Parkinson Disease: A Public Health Approach,” which serves as a valuable resource for various stakeholders. This brief outlines important action areas for intervention, including global health policies, prevention, education, awareness, and access to treatment and care.

Additionally, WHO’s iSupport program, designed as a knowledge and skills training program for carers of people living with dementia, offers resources that can be applied to support individuals with PD and their caregivers.

LATEST DEVELOPMENT

A groundbreaking advancement in the comprehension of Parkinson’s disease (PD) has emerged, revealing a novel tool capable of detecting a crucial hallmark of the condition: abnormal alpha-synuclein, often referred to as the “Parkinson’s protein,” present in both brain and body cells. This groundbreaking development, recently disclosed and published in the scientific journal The Lancet Neurology, heralds a new era in research, offering the potential for improved care and treatments for all individuals living with Parkinson’s. Additionally, it holds the promise that newly diagnosed patients may never progress to full-blown symptoms.

This innovative tool, named the α-synuclein seeding amplification assay (αSyn-SAA), not only identifies pathology in the spinal fluid of individuals already diagnosed with Parkinson’s but also in those who have not yet received a diagnosis or displayed clinical symptoms but are at a high risk of developing the condition.

The assay exhibits remarkable accuracy in confirming the presence of abnormal alpha-synuclein, a feature observed in the majority of PD cases. In fact, 93 percent of individuals with Parkinson’s who participated in the assay were shown to have abnormal alpha-synuclein. As Todd Sherer, PhD, Chief Mission Officer at The Michael J. Fox Foundation (MJFF), pointed out, “We’ve never previously been able to observe whether this alpha-synuclein biological alteration is occurring in a living individual.”

This significant breakthrough in biomarker identification was the result of collaborative efforts by an international coalition of scientists, spearheaded by the MJFF and its groundbreaking clinical study, the Parkinson’s Progression Markers Initiative (PPMI). Its importance as a milestone in the quest for a cure and enhanced treatments and therapies for Parkinson’s is underscored in an article featured on the prominent health and science news website STAT. The article emphasizes that “The real prize here is science — more precisely, research backed by the Michael J. Fox Foundation for Parkinson’s Research, which has provided the clearest evidence to date that the presence of a specific misfolded protein, alpha-synuclein, can serve as a diagnostic indicator for Parkinson’s. This breakthrough may soon lead to the development of superior diagnostics and, more importantly, could significantly expedite the quest for effective treatments for the disease.”

Alpha-synuclein, a protein typically present in the nervous system, akin to amyloid in Alzheimer’s disease, can undergo misfolding and aggregation, causing harm to neurons and the development of Parkinson’s disease. Previously, the confirmation of the existence of these aggregates was only attainable through postmortem analysis.
