The motor neurone diseases (or motor neuron diseases) (MND) are a group of progressive neurological disorders that destroy motor neurones, the cells that control voluntary muscle activity including speaking, walking, breathing, swallowing and general movement of the body.


Forms of motor neurone disease include:

  • amyotrophic lateral sclerosis (ALS) (sometimes called Lou Gehrig’s disease)
  • primary lateral sclerosis (PLS)
  • progressive muscular atrophy (PMA)
  • bulbar[1]
    • pseudobulbar palsy – spastic
    • progressive bulbar palsy – spastic and flaccid

Spinal muscular atrophy (SMA) is classified under MND by MeSH, but not by ICD-10.


In this article, MND refers to a group of diseases which affect the motor neurones. In the United States, the term ALS is more commonly used, where it is also known as Lou Gehrig’s disease, after the baseball player. Although previously described by other neurologists of the 19th century, it was Jean-Martin Charcot, a French neurologist, who suggested grouping together a number of disparate conditions all affecting the lateral horn of the spinal cord in 1869. In France the disease is sometimes known as Maladie de Charcot (Charcot’s disease), although it may also be referred to by the direct translation of ALS, Sclerose Laterale Amyotrophique (SLA). To help prevent confusion, the annual scientific research conference dedicated to the study of MND is called the International ALS/MND Symposium.

Signs and symptoms of Motor neurone disease

Symptoms usually present themselves between the ages of 50-70, and include progressive weakness, muscle wasting, and muscle fasciculations; spasticity or stiffness in the arms and legs; and overactive tendon reflexes. Patients may present with symptoms as diverse as a dragging foot, unilateral muscle wasting in the hands, or slurred speech.

Neurological examination presents specific signs associated with upper and lower motor neurone degeneration. Signs of upper motor neurone damage include spasticity, brisk reflexes and the Babinski sign. Signs of lower motor neurone damage include weakness and muscle atrophy.

Note that every muscle group in the body requires both upper and lower motor neurones to function. The signs described above can occur in any muscle group, including the arms, legs, torso, and bulbar region.

The symptoms described above may resemble a number of other rare diseases, known as “MND Mimic Disorders”. These include, but are not limited to multifocal motor neuropathy, Kennedy’s disease, hereditary spastic paraplegia, spinal muscular atrophy and monomelic amyotrophy. A small subset of familial MND cases occur in children, such as “juvenile ALS”, Madras syndrome, and individuals who have inherited the ALS2 gene. However, these are not typically referred to as MND, but by their specific names.

Diagnosis for Motor neurone disease

The diagnosis of MND is a clinical one, established by a neurologist on the basis of history and neurological examination. There is no diagnostic test for MND. Investigations such as blood tests, electromyography (EMG), magnetic resonance imaging (MRI), and sometimes genetic testing are useful to rule out other disorders that may mimic MND. However, the diagnosis of MND remains a clinical one. Having excluded other diseases, a relatively rapid progression of symptoms is a strong diagnostic factor. Although an individual’s progression may sometimes “plateau”, it will not improve.

A set of diagnostic criteria called the El Escorial criteria[2][3] have been defined by the World Federation of Neurologists for use in research, particularly as inclusion/exclusion criteria for clinical trials. Owing to a lack of clinical diagnostic criteria, some neurologists use the El Escorial criteria during the diagnostic process, although strictly speaking this is functionality creep, and some have questioned the appropriateness of the criteria in a clinical setting.[4]

Type UMN degeneration LMN degeneration
ALS yes yes
PLS yes no
PMA no yes
Progressive bulbar palsy no yes – bulbar region
Pseudobulbar palsy yes – bulbar region no

The “bulbar region” in the table above refers to the mouth, face, and throat.

It it possible that Transcranial Magnetic Stimulation can be used to diagnose MND.[5]


Most cases of MND progress quite quickly, with noticeable decline occurring over the course of months. Although symptoms may present in one region, they will typically spread. If restricted to one side of the body they are more likely to progress to the same region on the other side of the body before progressing to a new region. After several years, most patients require help to carry out activities of daily living such as self care, feeding, and transportation.

MND is typically fatal within 2-5 years. Around 50% die within 14 months of diagnosis. The remaining 50% will not necessarily die within the next 14 months as the distribution is significantly skewed. As a rough estimate, 1 in 5 patients survive for 5 years, and 1 in 10 patients survive 10 years.[citation needed] Professor Stephen Hawking is a well-known example of a person with MND, and has lived for more than 40 years with the disease.

Mortality normally results when control of the diaphragm is impaired and the ability to breathe is lost. One exception is PLS, which may last for upwards of 25 years. Given the typical age of onset, this effectively leaves most PLS patients with a normal life span. PLS can progress to ALS, decades later.


Causes of Motor neurone disease

About 90% of cases of MND are “sporadic”, meaning that the patient has no family history of ALS and the case appears to have occurred with no known cause. Genetic factors are suspected to be important in determining an individual’s susceptibility to disease, and there is some weak evidence to suggest that onset can be “triggered” by as yet unknown environmental factors (see ‘Epidemiology’ below).

Approximately 10% of cases are “familial MND”, defined either by a family history of MND or by testing positive for a known genetic mutation associated with the disease. The following genes are known to be linked to ALS: Cu/Zn superoxide dismutase SOD1, ALS2, NEFH (a small number of cases), senataxin (SETX) and vesicle associated protein B (VAPB).

Of these, SOD1 mutations account for some 20% of familial MND cases. The SOD1 gene codes for the enzyme superoxide dismutase, a free radical scavenger that reduces the oxidative stress of cells throughout the body. So far over 100 different mutations in the SOD1 gene have been found, all of which cause some form of ALS(ALSOD database). In North America, the most commonly occurring mutation is known as A4V and occurs in up to 50% of SOD1 cases. In people of Scandinavian extraction there is a relatively benign mutation called D90A which is associated with a slow progression. Future research is concentrating on identifying new genetic mutations and the clinical syndrome associated with them. Familial MND may also confer a higher risk of developing cognitive changes such as frontotemporal dementia or executive dysfunction (see ‘extra-motor change in MND’ below).

It is thought that SOD1 mutations confer a toxic gain, rather than a loss, of function to the enzyme. SOD1 mutations may increase the propensity for the enzyme to form protein aggregates which are toxic to nerve cells.


Skeletal muscles are innervated by a group of neurones (lower motor neurones) located in the ventral horns of the spinal cord which project out the ventral roots to the muscle cells. These nerve cells are themselves innervated by the corticospinal tract or upper motor neurones that project from the motor cortex of the brain. On macroscopic pathology, there is a degeneration of the ventral horns of the spinal cord, as well as atrophy of the ventral roots. In the brain, atrophy may be present in the frontal and temporal lobes. On microscopic examination, neurones may show spongiosis, the presence of astrocytes, and a number of inclusions including characteristic “skein-like” inclusions, bunina bodies, and vacuolisation.

There is a role in excitotoxicity and oxidative stress, presumably secondary to mitochondrial dysfunction. In animal models, death by apoptosis has also been identified.

Emotional lability / pseudobulbar affect

Around a third of all MND patients experience labile affect, also known as emotional lability, pseudobulbar affect, or pathological laughter and crying. Patients with pseudobulbar palsy are particularly likely to be affected, as are patients with PLS.

Extra-motor change in MND

Cognitive change occurs in between 33–50% of patients. A small proportion exhibit a form of frontotemporal dementia characterised by behavioural abnormalities such as disinhibition, apathy, and personality changes. A small proportion of patients may also suffer from an aphasia, which causes difficulty in naming specific objects. A larger proportion (up to 50%) suffer from a milder version of cognitive change which primarily affects what is known as executive function. Briefly, this is the ability of an individual to initiate, inhibit, sustain, and switch attention and is involved in the organisation of complex tasks down to smaller components. Often patients with such changes find themselves unable to do the family finances or drive a car. Depression is surprisingly rare in MND (around 5–20%) relative to the frequency with which it is found in other, less severe, neurological disorders e.g. ~50% in multiple sclerosis and Parkinson’s disease, ~20% in Epilepsy. Depression does not necessarily increase as the symptoms progress, and in fact many patients report being happy with their quality of life despite profound disability. This may reflect the use of coping strategies such as reevaluating what is important in life.

Although traditionally thought only to affect the motor system, sensory abnormalities are not necessarily absent, with some patients finding altered sensation to touch and heat, found in around 10% of patients. Patients with a predominantly upper motor neurone syndrome, and particularly PLS, often report an enhanced startle reflex to loud noises.

Neuroimaging and neuropathology has demonstrated extra-motor changes in the frontal lobes including the inferior frontal gyrus, superior frontal gyrus, anterior cingulate cortex, and superior temporal gyrus. The degree of pathology in these areas has been directly related to the degree of cognitive change experienced by the patient, if any. Patients with MND and dementia have been shown to exhibit marked frontotemporal lobe atrophy as revealed by MRI or SPECT neuroimaging.


The incidence of MND is approximately 1–5 out of 100,000 people. Men have a slightly higher incidence rate than women. Approximately 5,600 cases are diagnosed in the U.S. every year. By far the greatest risk factor is age, with symptoms typically presenting between the ages of 50-70. Cases under the age of 50 years are called “young onset MND”, whilst incidence rates appear to tail off after the age of 85.

Tentative environmental risk factors identified so far include: exposure to severe electrical shock leading to coma, having served in the first Gulf War, and playing Association football (soccer). However, these findings have not been firmly identified and more research is needed.

There are three “hot spots” of MND in the world. One is in the Kii peninsula of Japan, one amongst a tribal population in Papua New Guinea. Chamorro inhabitants from the island of Guam in the Pacific Ocean have an increased risk of developing a form of MND known as Guamanian ALS-PD-dementia complex or “lytico bodig”, although the incidence rate has declined over the last 50 years and the average age of onset has increased.[6] Putative theories involve neurotoxins in the traditional diet including cycad nut flour and bats that have eaten cycad nuts.[7][8]

Treatment of Motor neurone disease

Currently there is no cure for ALS. The only drug that affects the course of the disease is riluzole. The drug functions by blocking the effects of the neurotransmitter glutamate, and is thought to extend the lifespan of an ALS patient by only a few months.

The lack of effective medications to slow the progression of ALS does not mean that patients with ALS cannot be medically cared for. Instead, treatment of patients with ALS focuses on the relief of symptoms associated with the disease. This involves a variety of health professionals including neurologists, speech-language pathologists, physical therapists, occupational therapists, dieticians, respiratory therapists, social workers, palliative care specialists, specialist nurses and psychologists. A list of neurology clinics that specialize in the care of patients with ALS can be found on the World Federation of Neurology website (

Research efforts

The search for a drug that will slow MND progression is under way. Agents that are currently in trials include ceftriaxone, arimoclomol, IGF-1 and coenzyme Q10 to name but a few.


Amyotrophic comes from the Greek language: A- means “no”, myo refers to “muscle”, and trophic means “nourishment”; amyotrophic therefore means “no muscle nourishment,” which describes the characteristic atrophication of the sufferer’s disused muscle tissue. Lateral identifies the areas in a person’s spinal cord where portions of the nerve cells that are affected are located. As this area degenerates it leads to scarring or hardening (“sclerosis”) in the region.

Homeopathy Treatment for Motor neurone disease

Keywords: homeopathy, homeopathic, treatment, cure, remedy, remedies, medicine

Homeopathy treats the person as a whole. It means that homeopathic treatment focuses on the patient as a person, as well as his pathological condition. The homeopathic medicines are selected after a full individualizing examination and case-analysis, which includes the medical history of the patient, physical and mental constitution, family history, presenting symptoms, underlying pathology, possible causative factors etc. A miasmatic tendency (predisposition/susceptibility) is also often taken into account for the treatment of chronic conditions. A homeopathy doctor tries to treat more than just the presenting symptoms. The focus is usually on what caused the disease condition? Why ‘this patient’ is sick ‘this way’. The disease diagnosis is important but in homeopathy, the cause of disease is not just probed to the level of bacteria and viruses. Other factors like mental, emotional and physical stress that could predispose a person to illness are also looked for. No a days, even modern medicine also considers a large number of diseases as psychosomatic. The correct homeopathy remedy tries to correct this disease predisposition. The focus is not on curing the disease but to cure the person who is sick, to restore the health. If a disease pathology is not very advanced, homeopathy remedies do give a hope for cure but even in incurable cases, the quality of life can be greatly improved with homeopathic medicines.

The homeopathic remedies (medicines) given below indicate the therapeutic affinity but this is not a complete and definite guide to the homeopathy treatment of this condition. The symptoms listed against each homeopathic remedy may not be directly related to this disease because in homeopathy general symptoms and constitutional indications are also taken into account for selecting a remedy. To study any of the following remedies in more detail, please visit the Materia Medica section at Hpathy.

None of these medicines should be taken without professional advice and guidance.
