The main symptom of pseudobulbar paralysis?

summary

Pseudobulbar palsy is an uncommon disease. It is due to the loss of the upper motor neurons innervation of the medullary motor cranial nucleus, resulting in bulbar paralysis. What are the symptoms of pseudobulbar paralysis? Let's see.

The main symptom of pseudobulbar paralysis?

First, pseudobulbar palsy has "three difficulties.". The earliest symptom is usually speech difficulty, that is, when the patient wants to speak, the lip almost does not move because of muscle spasm. The sounds are spasmodic, explosive, and incomprehensible. If you are too excited, the speech difficulty is more serious. In addition, another symptom of speech difficulty is the repetition of the same language, that is to say a sentence or a paragraph repeatedly; The following diseases are dysphonia and dysphagia. First of all, dysphonia means that the voice characteristics of the patient will disappear and become monotonous, hoarse and blunt, just like anyone's voice. Or vice versa; When pseudobulbar palsy develops to a certain extent, it will be difficult to eat. Because of masticatory muscle spastic paralysis, patients will clench their teeth, or teeth can not be closed, food often fall out. If the food is pushed into the pharyngeal cavity, the patient can still rely on reflex activities to complete eating. But in the late stage, the swallowing reflex of pseudobulbar palsy will also be lost, and the nutrition can only be maintained by nasal feeding.

Because pseudobulbar palsy is a kind of upper neuron palsy, there will be some pathological brainstem reflex, most of which are primitive reflex in infancy and will be inhibited when they grow up. Such as sucking reflex, palmomaxillary reflex, head up reflex, corneal mandibular reflex.

Patients with pseudobulbar palsy also have emotional disorders. When you are alone, your expression is indifferent and monotonous. Stimulated will suddenly appear strong cry and smile symptoms. Stimulation is often without reason.

matters needing attention

Above is the common clinical symptoms of pseudobulbar paralysis, in addition, there will be mental retardation, dysuria, more or less limb motor paralysis, occasionally cerebral flexion paraplegia. Because of the particularity of the nervous system, early detection and early search for the cause of the disease are of great help to the treatment. Otherwise, once the nervous system has formed substantial damage, it will be quite difficult to recover.
