Initial symptoms of motor neuron disease?

summary

When the motor neuron appears, it will cause serious damage to the health of patients. Many patients will have symptoms of muscle weakness when they are exercising. When the symptoms of motor neuron disease are found, what are the initial symptoms of motor neuron disease? Now let me tell you something.

Initial symptoms of motor neuron disease?

Mixed type of upper and lower motor neurons: usually hand muscle weakness, atrophy as the first symptom, generally from one side and then spread to the opposite side, with the development of the course of disease appear mixed damage symptoms of upper and lower motor neurons, called amyotrophic lateral sclerosis. Generally, the lower motoneurons of the upper limb are seriously damaged, but the muscle tension can be increased, the tendon reflex can be active, and there is pathological reflex. When the motor meridians are seriously damaged, the symptoms of upper motoneuron damage of the upper limb can be covered up.

Upper motoneuron type: weakness, tightness and inflexibility of limbs. Because the disease often invades the corticospinal tract of the lower thoracic spinal cord, the symptoms of motor neurons start from the lower limbs, then spread to the upper limbs, and the lower limbs are more severe. Weak limb strength, increased muscle tension, difficulty in walking, spasmodic scissors gait, hyperreflexia of tendon, positive pathological reflex. If the lesion involved bilateral cortical brainstem, pseudobulbar palsy symptoms appeared, such as clear pronunciation, dysphagia, mandibular hyperreflexia, etc. This disease is called primary lateral sclerosis. It is rarely seen in clinic. It usually starts in adulthood and progresses very slowly.

Lower motor neuron type: more than 30 years old. It usually starts with weakness and atrophy of small muscles in the hand, which can affect one or both sides, or from one side to the other. Because the size of thenar muscle atrophy and flat palm, interosseous muscle atrophy and claw hand. What are the clinical manifestations of motor neurons? Muscle atrophy extended upward and gradually invaded the forearm, upper arm and shoulder belt. Muscle strength, muscle tension and tendon reflex were weakened or disappeared.

matters needing attention

In life, patients should have a healthy body, do not have too much pressure, the greater the pressure, the motor neuron disease will be more difficult to recover, in life, patients should develop good habits, timely rehabilitation and treatment, I wish patients good health, early recovery.
