Hence, most of the signs and symptoms of vagus nerve dysfunction, apart from vocalisation, are vague and non specific. Laryngeal nerve palsy results in paralysis of an ipsilateral vocal cord and is used as a pointer to diseases affecting the vagus nerve from its origin down to termination of its branch of the laryngeal nerve. Sensory neuropathy
In contrast, pseudobulbar palsy is a clinical syndrome similar to bulbar palsy but in which the damage is located in upper motor neurons of the corticobulbar tracts in the mid-pons (i.e., in the cranial nerves IX-XII), that is the nerve cells coming down from the cerebral cortex innervating the motor nuclei in the medulla.
Episodes of vasovagal syncope are typically recurrent and usually occur when the predisposed person is exposed to a specific trigger. Before losing consciousness, the individual frequently experiences early signs or symptoms such as lightheadedness, nausea, the feeling of being extremely hot or cold (accompanied by sweating), ringing in the ears, an uncomfortable feeling in the heart, fuzzy ...
The vagus nerve is part of the parasympathetic nervous system, often called the “rest and digest” system because it helps the body relax after periods of stress and regulates bodily functions ...
The results of the trial, published last month in a pair of studies in the journal Brain Stimulation, show that stimulating the vagus nerve can alleviate depressive symptoms, improve life quality ...
These disorders are characterized by the degeneration of motor neurons in the cerebral cortex, spinal cord, brain stem, and pyramidal tracts. This specifically involves the glossopharyngeal nerve (IX), vagus nerve (X), and hypoglossal nerve (XII). [2] This disorder should not be confused with pseudobulbar palsy or progressive spinal muscular ...
Hot fluids may be helpful for some people with cricopharyngeal spasm (or other oesophageal disorders). [3] Herbal tea. Other therapies. Transcutaneous stimulation of vagus nerve through the ear [4] proved to reduce symptoms of that family (long lasting, on the way of the vagus nerve) according to a study realized in the context of long covid. [2]
The findings align with prior research suggesting that misfolded alpha-synuclein proteins may spread from the gut to the brain via the vagus nerve, offering further support for the hypothesis that ...
