What reason is pharyngeal bulb paralysis?

summary

Bulbar paralysis, also known as bulbar paralysis, is divided into nuclear and subnuclear, also known as true bulbar paralysis and pseudo bulbar paralysis. The common clinical characteristics of these two types of bulbar paralysis are speech difficulty, dysphonia and dysphagia. It brings great inconvenience to patients' daily life. So what's the cause of bulbar paralysis.

What reason is pharyngeal bulb paralysis?

Reason 1: the main manifestations of bulbar paralysis are speech difficulty, dysphonia and eating difficulty. Among them, speech difficulty is the earliest symptom of bulbar paralysis. Patients with dysarthria are prone to fatigue, especially when they need to improve their voice and accentuate their intonation. With the gradual development of the disease, paralysis of articulation structures such as tongue, lip and throat gradually appeared. The loss of bilateral vagus motor function is the cause of dysphonia.

The second reason is that the ninth, tenth, eleventh and twelfth pair of cranial nerves emitted from the medulla oblongata are called posterior group cranial nerves. The main function of these posterior group cranial nerves is to control the movement of tongue and pharynx. The injury of posterior group cranial nerves is the main cause of bulbar paralysis and dysphagia

The third reason is that the IX, x, Xi and Ⅻ in the cranial nerves are dominated by the bilateral cortical brainstem tracts. If the unilateral cortical brainstem tracts are damaged, there may not be bulbar palsy. Bulbar palsy occurs when bilateral cortical brainstem tracts are damaged. Bilateral damage directly results in tongue immobility.

matters needing attention

At present, there is no special treatment for bulbar paralysis, and there is no specific medicine, so it can only be treated according to the symptoms. Patients should pay attention to eat high nutrition, high protein, high vitamin food to improve their immunity. At the same time, appropriate vasodilators and neurotrophic agents can be given. At the same time, we should pay attention to supplement the body's heat to prevent infection.
