In the language of physicians, hand trembling (or tremor) is physiological and pathological. In the first case, this phenomenon is temporary and disappears immediately after the elimination of the causes that caused it. But if the hand tremor is caused by some pathological process in the body, then appropriate measures will have to be taken. Let’s take a closer look at the causes of tremor.
Why hands tremble: physiological reasons
Physiological tremor occurs in otherwise healthy people. This is a tremor during movements or body positions, more often approximately equally expressed in both hands; the amplitude is usually small. Often it appears only on the background of some stress. Stress factors include: • Anxiety • Fatigue • Exercise • Sleep deprivation • Some medical conditions (eg, hyperthyroidism) when clinically present • Use of caffeine or recreational drugs such as cocaine, amphetamines, phencyclidine • Use of certain medications, such as as corticosteroids and valproates (topiramate, gabapectin), etc.
Pathological (non-physiological) tremor in children occurs with the following diseases:
• hereditary diseases: Wilson’s disease, Fredreich’s disease, etc. • Dysfunction of the cerebellum (for example, due to stroke, trauma, or multiple sclerosis, TBI, tumors) • Endocrine and metabolic diseases (hyperthyroidism, hypoglycemia, hyperparathyroidism) • Peripheral neuropathy , Guillain-Barré syndrome.
Examination of body systems should include a search for symptoms that indicate the cause of the disease, including:
• several episodic neurological problems: multiple sclerosis;
• recent sudden motor weakness, speech disorders or dysarthria: stroke;
• confusion and fever: meningitis, encephalitis, brain abscess or brain tumor; • weight loss, increased appetite, palpitations, diarrhea and heat intolerance: hyperthyroidism; • sensory deficit: peripheral neuropathy.
Pathological causes of tremor
Physiological tremor. If its manifestations are not burdensome for the patient, no treatment is required. Triggers (eg, caffeine, fatigue, lack of sleep, medications, and, when possible, stress and anxiety) should be avoided to prevent or reduce symptoms whenever possible.
Increased physiological tremor due to hyperthyroidism is reduced when the underlying condition is corrected.
Among other things, trembling in the hands can be of a hereditary origin. In this case, as a rule, all family members suffer, and the first signs of tremor appear at a young age.
First of all, it is necessary to identify the cause of the hand trembling. If the cause is physiological, then it is enough to eliminate it to normalize the condition. To calm down and relieve nervous tension, you can take soothing medicinal preparations, infusions of valerian or motherwort, such as Persen, Tenoten, Negrustin, and the like.
When tremor accompanies any pathological process in the body, it is necessary to consult a specialist doctor who will conduct a comprehensive examination and prescribe the appropriate therapy for the case.
Only a doctor will prescribe certain medications that can normalize the course of diseases, many of which are chronic.
If a number of neurological diseases are detected, the patient can be treated surgically. Currently, stimulation electrodes are being installed that can block the activity of the extrapyramidal nuclei – such operations are called stimulation of the deep structures of the DBS.
Also, exercises aimed at developing fine motor skills help get rid of hand tremors. It is very useful to knit, embroider, weave from beads, in a word, try to perform precise actions with the hands. Moreover, such exercises are relevant for both adults and children, and in addition to the therapeutic effect, it is also a very pleasant way to spend time with your family. After all, drawing, knitting, and embroidering can be interesting for both adults and kids.
