What and when do we tremble? – Causes of tremors

Tremors are strongly influenced by stress

To understand neurological diseases, it is worth reviewing the relevant anatomy a little. Movement regulation takes place in two ways in the nervous system between the cerebral cortex and the muscles. One is the pyramidal pathway, which goes from the large motoneurons of the cerebral cortex directly to the motoneurons of the spinal cord. Voluntary movements run on this track, which we consciously plan and execute. The rest of the movements run on the extrapyramidal tracks, that is, they reach the spinal cord through a complicated track system. Movements that are carried out without our attention, such as walking, eating, and practiced writing, run on it.

Tremor is the so-called it belongs to extrapyramidal movement disorders, it is an arousal phenomenon, which is greatly influenced by the state of arousal and the level of stress. The more tense a person is, the easier it is for tremors to occur.

There are several types of tremors

Within tremor, one type is rest tremor, when, for example, the limb is lying peacefully on the bed, and then the tremor occurs. There is also the so-called static tremor, the characteristic test method of which is that the patient extends his hand, spreads his fingers, and then the tremor becomes visible. In addition, there is an intention tremor, which in the typical examination position requires the patient to touch the nose with the index finger with the eyes closed. In this case, the tremor with a larger wave becomes visible, and the patient may not even hit the target.

Not only Parkinson’s disease can cause tremors

– Most patients are frightened by even a slight hand tremor and think they have Parkinson’s, even though this is a very rare disease at a young age. You should also know that only one of its symptoms is intention or rest tremor, all other symptoms together characterize Parkinson’s disease. In other words, muscle stiffness, joint stiffness, slowing down of walking, changes in writing, difficulty eating, and larva-like transformation of the facial muscles must be present in order to be diagnosed with Parkinson’s disease. Parkinsonian tremors are typically experienced during current writing and the so-called measure by drawing a spiral line. When the patient draws a spiral line growing outwards with both hands, the shaking line appears in the Parkinson’s patient. This test can also be used to monitor therapy, explains Dr. Géza Prinz, neurologist, psychiatrist, infectologist at the Neurological Center.
Among neurological diseases, essential tremor is much more common, the name of which also indicates that its origin is not exactly known. It is a hand and head tremor with a fine wave, showing a very close connection with nervous tension, which can be voluntarily influenced. If we ask such a patient to do something, the tremors stop. This phenomenon occurs even at a younger age, and its therapy is completely different from that of Parkinson’s disease.

The cause of the tremor can be found elsewhere

Dr. Prinz’s words revealed the two most common neurological causes of tremors. Other hand tremors are more of a borderline phenomenon. For example, hand tremors associated with alcohol withdrawal are well-known, which is a consequence of the release of alcohol-induced nerve cell inhibition, and is usually accompanied by malaise, flushing, overheating, and in more severe cases, loss of consciousness. Tremor occurring in liver patients is a similarly internal medical condition, which is a liver cirrhosis can be detected in an advanced state.
It is more common that a in diabetic patients a drop in blood sugar can cause shaking throughout the body, accompanied by sweating. (This requires quick intervention before the disturbance of consciousness develops.) This phenomenon can be very similar to the tremors that occur during panic attacks, although at first the patient experiences it more as an internal tremor, and the patient may also experience rapid heartbeat and great fright.
It is also important to check not only the blood sugar balance, but also the thyroid function also, because hyperactivity can also be characterized by a tendency to tremble. Even in old age, a patient whose hand trembles does not necessarily have Parkinson’s, since the so-called arteriosclerosis such a symptom can also be associated with brain damage caused by
The bottom line is that if a trembling condition occurs repeatedly, it is disturbing when communicating, writing, or eating, it is definitely worth seeing a doctor. In addition to/after laboratory examination of internal medicine conditions, the neurologist can accurately determine the diagnosis and prescribe the appropriate treatment.
