Motor Neurone Disease: Myths vs Facts You Need to Know

Sudden twitching, stumbling, or weakness experienced in arms or legs might appear harmless at the beginning. At times, such symptoms may require closer attention. Motor Neurone Disease (MND) is a progressive neurological disorder that affects nerve cells responsible for controlling movement. MND progression leads to difficulties with mobility, swallowing, speech, or breathing. Despite scientific advancement, Motor Neurone Disease is often associated with misconceptions. Understanding the facts is essential for early symptom recognition, making informed decisions and accessing supportive care. The current article unveils various MND misconceptions and states facts, discussing its types, symptoms and available diagnosis. 

Ask The Expert

What Is Motor Neurone Disease?

Motor Neurone Disease refers to the neurological condition that affects motor neurons. In normal conditions, a neurological message runs from the brain (upper motor neurons) to the spinal cord (lower motor neurons). The message further moves towards the muscle. The signalling network gets disrupted among individuals with MND. When the muscle does not receive adequate signals, it shrinks or weakens, leading to muscle atrophy. This leads to muscle stiffness and hyperreflexia (overactive reflexes). Currently, there is no cure. Ongoing research and therapeutics aim to manage symptoms and slow disease progression.   

Why Are Misconceptions Common in MND?

MND is a relatively uncommon condition and greatly lacks public awareness. The majority of individuals hear about MND through media reports or isolated patients’ stories. This does not provide adequate information about early symptoms and disease progression. The primary causes of misconceptions include:

• Limited public awareness, unaware of the early signs and symptoms
• Symptom similarity with other neurological disorders like muscle atrophy, weakness, cramps, etc.
• Often resembles other neurological disorders like Parkinson’s, peripheral neuropathy, cervical spondylosis, MS, etc.

Common Myths vs Facts About MND

Here are some common Myths and Facts related to Motor Neurone Disease

Myth: MND only affects older adults

Fact: >50% of MND cases are diagnosed among older adults (50-70 years). At the same time it can affect younger individuals 

Myth:  MND is inherited

Fact: Only 5%- 10% of MND cases are familial, while the majority are sporadic (90%)

Myth: Every MND patient experiences similar signs and symptoms

Fact: MND signs and symptoms can be highly variable. Factors like age, genetic makeup, disease progression pace, and symptom severity all differ

Myth: Individuals with MND do not experience pain

Fact: The nerve transmitting pain signals are not directly affected. Many patients experience intense pain associated with stiffness, immobility, cramps, etc.

Myth: There is no treatment available for MND

Fact: Various clinical interventions are available that can actively manage MND symptoms

Myth: Rehabilitation have no impact in MND care

Fact: Rehabilitations tailored based on an individual’s needs. It is essential in MND management. This includes mobility assessment, communication support, and the introduction of adaptive equipment. 

What are MND Types? 

Motor Neurone Disease Types depend on the affected neuronal region. The types include:

• Amyotrophic Lateral Sclerosis (ALS): Most common type, both upper and lower neurons are affected. Alternative name is Lou Gehrig’s. ALS leads to rapid loss of muscle control that progressively leads to paralysis
• Progressive Bulbar Palsy (PBP): PBP attacks lower motor neurons that are connected with the brainstem. The muscles responsible for speaking, chewing, swallowing, etc. are affected
• Primary Lateral Sclerosis (PLS): The upper motor region is affected. Initially, the legs are affected, followed by the arms, hands, and torso. 
• Progressive Muscular Atrophy (PMA): Only lower motor neurons are affected. This is most common among males at younger ages. Weakness in hands that spreads to the lower body is common. 
• Spinal Muscular Atrophy (SMA): Inherited condition caused by the SMN1 gene, leading to loss of SMN protein. The lower motor neurones are affected. This result in muscle wastage and eventually death. 

What are the MND Symptoms?

Motor Neurone Disease Symptoms Include:

• Progressive muscle atrophy in legs or arms
• Dysarthria (Slurred speech)
• Fasciculations (muscle twitching)
• Weaker grip, loss of hand function
• Pseudobulbar affect (trouble in stopping laughing or crying in inappropriate situations)
• Breathlessness and Fatigue
• Insomnia
• Repetitive chest infection

MND Diagnosis

Motor Neurone Disease Diagnosis Includes:

• Clinical neurological examination: Checking the affected area, symptoms, and changes with time
• Blood and Urine tests: Determining biological parameters
• Electromyography (EMG): Determination of muscular issues
• Nerve conduction studies: How fast the impulses are transmitted
• MRI: Brain MRI to determine abnormalities

What are the Available MND Treatments in India? 

Motor Neurone Disease Treatment in India involves a multidisciplinary approach. The therapeutic regime includes:

• Medication: Baclofen (relieves muscle tightness), phenytoin (muscle cramps), glycopyrrolate (drooling), antidepressants (depression), benzodiazepines (Pain management)
• Physical Therapy: Works on muscle strengthening and joint flexibility
• Assistive Devices: Gastrostomy tubes to combat swallowing difficulties. The tube enables nutrient transportation (abdominal wall to the stomach). Other devices like braces or orthotics aid with mobility
• Breathing Support: Respiratory support for the patient experiencing breathlessness. Non-invasive ventilation (NIV) for adequate breathing, sleep and fatigue management. 

*NOTE: The current conventional MND treatment in India intends to manage symptoms. None of the therapeutic options can significantly impact MND progression. This calls for the emergence of advanced therapy that targets the root cause of the problem.

MND Regenerative Medicine in India: What Does Current Research Say?

Regenerative medicine is evolving rapidly globally. The therapeutic area is still at an early stage, the outcomes look promising. They support multiple biological signals along with symptom management. The core mechanism includes:

• Regeneration of Motor Neurons: Neurons have limited capacity for rejuvenation. Cells cannot get naturally replaced. Stem cells modify the neuronal microenvironment in the spinal cord and make it more hospitable for cell survival
• Anti-Inflammation and Immunomodulation: Stem cells release various anti-inflammatory molecules (IL-6, IL-10) that neutralize pro-inflammatory signals. It combats underlying neuroinflammation. This modulates the immune response and regulates inflammatory pathways. 
• Neuroprotection: Stem cells release various neurotrophic factors that support neuronal survival. They regulate inflammatory signals and boost repair signals to promote neuronal survival.

*NOTE: MND stem cell treatment in India is still evolving and at an early stage of research and clinical application. It is crucial to set realistic goals by considering stem cells as supportive therapy. Key factors like stem cell quality, source, isolation procedure, severity of the condition, and individual factors influence treatment outcomes. Advancells, India, is a leading manufacturer of clinical-grade stem cells for various neurodegenerative disorders, including MND. The cells come with a Certificate of Authentication (CoA). 

Conclusion

Motor neurone disease represents several symptoms. The condition is life-threatening, and holds limited therapeutic success. Growing evidence of regenerative medicine as an alternative treatment brings hope for restoring lost motor function among MND patients. In the future, large-scale clinical evidence can establish treatment efficacy and safety among MND patients.
