Tongue tremor

Introduction Tongue tremor is caused by contraction of the lingual muscle fibers and may be related to stimulation of the cortical center and related cranial nerves. Can be seen in sublingual nerve palsy, hyperthyroidism, nutritional macrocytic anemia, Parkinson's disease and Parkinson's syndrome caused by various reasons, can also be found in the elderly and nervous. Epidemiological investigations have found that there are regional differences in the prevalence of Parkinson's disease, so people suspect that there may be some toxic substances in the environment that damage the brain's neurons.

Cause

1. Ageing.

2. Family heredity: In the long-term practice, medical scientists found that Parkinson's disease seems to have a tendency to family aggregation. The family members of patients with Parkinson's disease have a higher incidence than their normal counterparts.

3. Genetic susceptibility: Although the occurrence of Parkinson's disease is related to aging and environmental toxins, not all elderly people or people exposed to the same environment, even those who also consume large amounts of MPTP, will develop Parkinson's disease. Although patients with Parkinson's disease also have family agglomeration, no clear pathogenic genes have been found in patients with Parkinson's disease, indicating that the cause of Parkinson's disease is multifactorial.

Most people with Parkinson's disease develop after the age of 60, and occasionally those who are in their 20s. The onset is more insidious, showing a slow development, gradually worsening, mainly manifested as: tremor (often the first symptom), muscle rigidity, bradykinesia, posture gait Parkinson's syndrome abnormalities, mouth, pharynx, diaphragmatic dyskinesia.

Auxiliary examination: High-performance liquid chromatography can detect a decrease in cerebrospinal fluid and urine (high vanillic acid) levels. Brain CT can have widening of the sulcus and enlargement of the ventricles.

Differential diagnosis

Need to be identified with the following symptoms:

Tongue pain: Tongue pain refers to a syndrome of burning, burning pain, numbness, and pain in different parts of the tongue, tongue, tongue, tongue or whole tongue.

Glossopharyngeal nerve injury: The glossopharyngeal nerve is a mixed nerve that contains motor and sensory fibers. After the cranial fossa is passed through the cranial vein, the pharyngeal wall is reached between the internal and external carotid arteries. The sensory fiber is the sensory afferent nerve of the pharynx, and its motor branch is responsible for the soft palate function, and the parasympathetic fiber tube is secreted by the parotid gland. The glossopharyngeal nerve belongs to the posterior group of cranial nerves. The chance of traumatic injury is relatively small, mostly due to the fracture line and the jugular foramen. However, the lesion of the jugular vein in the posterior cranial fossa is easy to cause glossopharyngeal nerve damage.
