Do you know what is bulbar paralysis?

First, bulbar paralysis is also called bulbar paralysis. According to the location of the lesion, bulbar palsy can be divided into true bulbar palsy and pseudobulbar palsy: true bulbar palsy is caused by the lesions of the cranial motor nucleus (nucleus ambiguus and hypoglossal nucleus) in the medulla oblongata or the glossopharyngeal, vagus and hypoglossal nerves.

Second: pseudobulbar palsy refers to the bilateral cerebral cortex, brain stem bundle involved and caused by. Both of them have swallowing and pronunciation dysfunction in clinic, but the former shows atrophy of tongue muscle and muscle fibrillation, weakening or disappearing of pharyngeal wall reflex; the latter shows no atrophy of tongue muscle, existence of pharyngeal wall reflex, and hyperreflexia of mandible, with sucking reflex, crying and laughing.

Third: clinical manifestations, bulbar paralysis is mainly manifested as speech difficulties, voice disorders, eating difficulties. (1) speech difficulties: the earliest symptom of bulbar paralysis is often dysarthria, patients are prone to speak fatigue, especially in the need to improve the voice and accentuate the intonation. Later, along with the progress of the disease, gradually appeared tongue, lip, soft palate and throat and other articulation structure paralysis, (2) dysphonia: mainly due to the loss of bilateral vagus motor function, vocal cord movement, control of glottic cleft caused by laryngeal muscle paralysis. In the early stage, the vocal cords were weak, the pronunciation was low and rough, and in the later stage, the voice lost, and the breathing difficulty and wheezing were serious. (3) dysphagia: in patients with bulbar palsy, due to the paralysis of tongue muscle, soft palate and pharyngeal muscle, dysphagia, drinking water cough, disappearance of pharyngeal reflex and weakness of chewing and other complex symptoms of dysphagia occur successively.
