What is motor neurone damage?

Motor neuron injury is a type of disease in neurology, which mainly affects the upper and lower motor neurons. It is a relatively common chronic disease, and its types include primary lateral sclerosis, progressive bulbar palsy, amyotrophic lateral sclerosis, etc. The causes of this neuronal damage are relatively complex, such as metal element virus infection, or immune factors. In addition, genetics is also a cause of this disease. For ordinary people, they should pay attention to prevention in daily life, and also pay attention when exercising to prevent some infectious diseases and pay more attention to rest.

Causes

Because the condition of motor neuron damage is complicated, its cause is still unclear. Experts speculate that it is related to the following factors:

1. Metal elements: Researchers believe that it is related to the deficiency of certain metal elements and certain metal poisoning.

2. Viral infection and immunity: Some believe that it is a toxic disease, while others believe that it may damage the spinal cord and cause motor neuron disease. Immune function measured in patients revealed the formation of immune complexes, elevated immunoglobulins, and positive anti-ganglioside antibodies.

3. Genetic factors: Some scholars have calculated that 5%-10% of cases have a family genetic tendency, so it is believed that there are genetic factors.

symptom

Motor neuron damage is a group of progressive degenerative diseases that selectively invade the anterior horn cells of the spinal cord, the brain stem nuclei, and the pyramidal cells of the cerebral motor cortex. The disease often occurs in middle-aged and elderly people, with varying degrees of speed, including progressive spinal muscular atrophy, progressive bulbar palsy, and amyotrophic lateral sclerosis. Symptoms and signs of motor neuron damage include:

1. Unilateral or bilateral hand muscle weakness with obvious tremor, thenar and hypothenar motor neuron disease.

2. Upper limb muscle and scapular motor neuron disease, difficulty in raising hands, weakness in combing hair, spastic paralysis of lower limbs, slow walking, and scissor-like gait.

3. Hoarseness, atrophy of tongue muscles, slurred speech, difficulty swallowing, saliva leakage, choking when eating or drinking, difficulty breathing, and difficulty in coughing up sputum.

prevention

(1) Strengthen physical fitness and actively engage in physical exercise to prevent infectious diseases.

(2) Avoid engaging in toxic work and pay attention to the quality of drinking water.

(3) The course of motor neuron injury is long, and it is necessary to persist in taking gluttonous food and massage, strengthen functional training, and have regular check-ups.

(4) Avoid consanguineous marriage and actively participate in pre-marital and prenatal examinations and eugenics consultations.
