Parkinson’s disease (PD) is primarily managed by symptom management. Yet, treatment approaches do not restore the lost nerves. Globally, more than 10 million individuals are living with PD [1]. Infact, PD ranks as the second most common neurodegenerative disease after Alzheimer’s. This indicates an immense burden in the healthcare sector.
Currently, the evolution of regenerative medicine research is potentially transforming the treatment landscape. Parkinson’s Treatment with Regenerative Medicine research is targeting damaged nerve repair, regeneration of lost neurons, neuroprotection, and reducing neuroinflammation. Although regenerative medicine therapeutics are still being redefined through clinical research, they represent exciting frontiers in modern neurology. The current article explores distinct causes of PD, current treatment options, and how regenerative medicine research is redefining the modern therapeutic avenue.
What Causes Parkinson’s Disease?
Parkinson’s accounts for neurodegenerative disorder resulting in progressive movement disorder. Dopamine, neurotransmitter production in brain cells are disrupted resulting in tremors, slow movement, muscle stiffness, and imbalance. Clinically, PDs are categorized as:
- Idiopathic: The most common form; the exact cause is unknown. Researchers unveiled the role of inappropriate folding of the alpha-synuclein protein leading to clump formation. This results in the buildup of Lewis’ body, which damages brain cells.
- Familial: A genetic cause that occurs due to the transfer of inherited genes to the offspring.
The Primary Causes of Parkinson’s Include:
- Degeneration of dopamine-producing neurons
- A drop in dopamine production resulting in signalling disruption from the brain to the muscles
- Symptoms, including tremors, slow movements, and stiffness, appear.
- Ageing, gender (affects mostly males), environmental causes (prolonged exposure to manganese or pesticides), or presence of a genetic condition
- Increased oxidative stress, or neuroinflammation
What are the Symptoms of PD?
PD begins with mild symptom progression. Early symptoms include tremors, stiffness, and slowed movements. It can be subcategorized as:
Movement-Associated Symptoms Include:
- Slowed movement
- Tremors in the hands, legs, and arms during rest
- Muscle stiffness or rigidity
- Posture change during walking, turning, etc
- Altered facial movement
- Voice change, cramped handwriting
Non-Movement-Associated Symptoms Include:
- Sensory problems like loss of smell
- Insomnia or restlessness
- Change in mood, depression, stress or anxiety
- Constipation, digestive issues, or urinary urgency
- Drooling, difficulty in chewing
- Sexual dysfunction
PD treatment regime is based on its diagnosis, including medical examination, blood test, brain imaging (MRIs, CT scan, DaTscan)
How is Parkinson’s Disease Treated?
The current treatment regimen aids in symptom management and improves the quality of life of the patient. Clinicians recommend a combination of options as parkinson’s disease treatment in India:
Medication
- Carbidopa-levodopa, levodopa turns into dopamine in the brain, while carbidopa reduces side effects like nausea
- Dopamine agonist, acts as dopamine in the brain
- COMT inhibitor enables levodopa to be sustained
- Amantadine reduces involuntary movements
- Anticholinergics reduce tremors’
- MAO-B inhibitors breakdown of dopamine in the brain
Rehabilitation
- Physical therapy to support muscle strength, balance, walking, and strength
- Occupational therapy to help with daily life activities
- Speech therapy to help with swallowing or communication
Surgery
- Deep brain stimulation (DBS) for managing movement symptoms
Lifestyle Management
- Dietary intervention
- Regular physical activities
- Sleep cycle management
*NOTE: The above therapies aid in symptom management of PD; however, none can prevent neurodegeneration management
What Is Regenerative Medicine for Parkinson’s Disease?
Regenerative medicine is an evolving research area that targets altered cellular or molecular mechanisms. Parkinson’s treatment with regenerative medicine involves a groundbreaking approach that supports neural regeneration. Researchers are widely exploring stem cell therapy to replace and repair the lost or damaged neurons.
Mesenchymal Stem Cells (MSCs) are used for their potential in differentiating into specific cell types and paracrine signalling.
Parkinson’s Treatment with Stem Cells Undertakes the Following Mechanism, Including:
- Regeneration and Repair: MSCs release various cytokines and growth factors that support regeneration of the lost neuron. It supports dopamine neuron replacement. They activate the body’s natural repair mechanism and create a supportive microenvironment
- Anti-Inflammation and Immunomodulation: MSCs release various anti-inflammatory molecules that significantly reduce neuroinflammation. They modulate the immune response and minimize the risk of immune rejection
- Neurotrophic Supports: MSCs release various neurotrophic factors that support neuronal survival. They create a safer environment for neuroprotection
What Does Current Research Say About Parkinson’s Stem Cell Treatment?
Early Clinical Evidence Has Projected a Positive Trend with Parkinson’s Treatment with Stem Cells. This Includes:
- Neurotrophic Support: Stem cells release various neurotrophic factors, including BDNF, VEGF, and GDNF, that support the survival of nigrostriatal neurons and synaptic plasticity
- Immunomodulation: Stem cells release various anti-inflammatory molecules such as IL-6, IL-10 and neutralize the effect of pro-inflammatory signals. It downregulates TNF-α, IL-1β
- α-Synuclein Modulation: Stem cells deliver miRNAs via extracellular vesicles. It reduces aggregation and propagation of α-Synuclein
- Antioxidation: Promotes upregulation of SOD and catalases, mitigates the effect of oxidative stress caused due to mitochondrial dysfunction
- Anti-Apoptosis: MSCs inhibit neuronal apoptotic pathways by discouraging caspase activation. It protects dopaminergic neurons [2]
*NOTE: Parkinson’s Stem Cell Treatment has displayed multiple advantages with the introduction of MSCs. The implication of stem cells for PD is still at an early stage of application. Large-scale clinical trials are desirable to establish their long-term efficacy, tolerance, and safety.
Who Could Benefit from Regenerative Medicine Approaches?
Determining treatment suitability is key to any treatment success. Parkinson’s Treatment with regenerative medicine is suitable for candidates including:
- Patient at early-to-moderate stage of PD
- Individuals with muscle symptoms despite the medication
- Individuals with preserved cognitive function have no severe dementia
- Patient with overall good physical health
- The candidate and their caregiver are ready for a long-term commitment
- The patients must develop realistic expectations, understand that Parkinson’s Stem Cell Treatment is yet emerging and not yet a definitive cure
*Advancells, India, is a leading manufacturer of clinical-grade stem cells suitable for neurodegenerative conditions like Parkinson’s
What are the Key Challenges?
Parkinson’s treatment with stem cells is at an early stage of clinical application. The key challenges include:
- The outcome differs among individuals, quality of stem cells, isolation procedure, source, administration protocol, and the individual’s response; everything matters
- The safety and tolerance are positive, but there is no long-term data available to determine its efficacy
- The progress occurs gradually; individuals expecting a quick response are not suitable.
Conclusion
The current treatment regime for Parkinson’s Disease Treatment in India and globally focuses on symptom management. With the emergence of Parkinson’s Treatment with Regenerative Medicine, regeneration and repair of lost neurons can potentially occur. Clinicians and stem cell researchers are collaborating to introduce Parkinson’s Stem Cell Treatment along with conventional therapy as a supportive treatment regimen.
