MND – Motor Neuron Disease

MND or motor neuron disease is a disease wherein assault is raged on the upper and lower motor neurones causing weakness and muscle wastage, progressive immobility in the limbs, speech problems, difficulty in ingestion and respiration. Neurones are dedicated cells that convey electrical nerve impulses and hence transmit information through all parts of the body. Not all having MND have such symptoms – for instance a person having MND could have entirely decipherable speech all through the condition.

Sporadic MND

Majority of the individuals developing MND are inflicted with sporadic MND meaning there is no case of family history and there is a rare likelihood of it developing in other kin members. The causes leading to MND are still unknown. Conceivably, several factors are involved and in an individual developing MND there could be composite reasons instead of merely a single causative factor. Many factors could raise the risk of MND developing or might aid in triggering it, though not capable of being causative factors by themselves.

Numerous likely risk factors have been indicated inclusive of:

• Being exposed to chemicals, particularly in the agricultural area and on food, but additionally noted among those who worked as fire-fighting personnel and those who installed industrialized equipment.
• Fractures and wounds that are sports-related, injuries to the head and leg.
• Those who smoked.
• Previously undergone course of chemotherapy and surgery.
• A high-stress lifestyle or certain increasingly stress-provoking incidents.
• Certain kinds of diets.
• Particular kinds of anti-depressant medications.
• Amalgamated tooth fillings.
• Having infections of the throat, certain viruses.
• Lyme disease.
• Recurrent travelling (inclusive of muscle cramps that occur due to remaining in a stationary posture for protracted periods of time).

Familial or Heritable MND

In five to ten percent of the cases, MND is observed to run in families, in nearly twenty percent of the cases, a certain gene bearing mutations, the SOD-1 gene or superoxide dismutase has been detected.

The age in which the person becomes symptomatic, the kind of inception and the rate of progression could differ in each individual in familial MND as they could in the case of sporadic MND.

Symptoms of MND

• The foremost symptoms of MND differ in each case with some experiencing weakness or rigidity in their limbs whereas others felt the effect on their hands or arms. Such symptoms are characteristic of the most prevalent kind of MND known as amyotrophic lateral sclerosis (ALS).
• Greater difficulty when one walks, exercises or climbs stairs mostly leading to tripping or falling.
• Some experience foot dropping wherein one foot is dragging or dropping obstructing normal walking. This could particularly become apparent among those individuals that engaged in sports, golf or fitness training.
• Some initially experienced their foremost signs in the area around their throat or oral area called as bulbar onset MND affecting nearly twenty-five percent of individuals with MND. Slurry speech could at times occur gradually or abruptly.
• Atypical symptoms like swift muscular contractions in the stomach and legs alike a sensation of having butterflies.
• Problems with coughing or while breathing or have choking fits.

Less commonly noted MND Diagnosis

Some diagnosed with MND would at times be having an atypical kind of condition like PLS or primary lateral sclerosis or PMA (progressive muscular atrophy). PLS is known to affect solely the upper motor neurones and PMA is known to affect solely the lower motor neurones.

In PLS, the limbs, hands or talking, sense of control when one walks are majorly affected. In PMA, generally the hands or the limbs are generally affected.

Individuals having these kinds usually have longer existence as compared to those having more prevalent kinds of MND and lifetime in PLS could be usual, though they would have several of the analogous problems of raised disabilities.
