Causes of tremors in the hands
Hand tremor is one of the disorders that can affect a person’s life and ability to complete daily tasks.
But it usually does not endanger his health and may be one of the early symptoms or signs of some degenerative and
And hand tremors can defined as a series of movements Although tremors can occur in various parts of the body.
Such as the arms, legs, head, and vocal cords.
It most commonly appears in the hands.
Knowing that the tremor of the hands may be unknown in some cases or may
be caused by some health disorders that affect the brain as it is in most cases.
And we show the following common causes of hand tremors in some detail:
Physiological tremor one of causes of tremors in the hands
Physiologic tremor is a type of tremor that occurs at a low rate and frequency in the hands.
In most cases, the person does not feel it, and it caused by carrying heavy weights or pulling one of the limbs against
the direction of gravity.
So this tremor known as a kinetic tremor.
This type of tremor can seen when extending the hand and placing a piece of paper on it, and it has an impact.
The type of tremor is mostly on both ends of the body and does not cause concern because physiological tremor is
one of the body’s natural reactions and not caused by the presence of a nervous disorder in the person.
And this type of tremor disappears when the cause removed.
And the following are some examples of physiological tremor causes:
- Consumption of high amounts of caffeine.
- Extreme hunger, fatigue or exhaustion.
- Exposure to emotional stress.
Use of some medicines
Some medications may cause hand tremors as a side effect or as a withdrawal symptom.
The following is a list of medications that may cause hand tremors:
- lithium medication.
- Anticonvulsants or antiseizure drugs
- Theophylline medication.
- Amiodarone, used to treat ventricular fibrillation disorder
- One of the withdrawal symptoms of benzodiazepines.
There are a number of movement disorders that can be accompanied by hand tremors, and the following are some of these disorders:
Essential tremor is one of the most common types of movement disorders, and as the term implies.
The cause of this type of tremor is still unknown, with genetic causes likely in nearly half of the cases, and this type of
tremor is not curable.
It is more effective in the hand that is usually used, with an overall effect on both ends of the body.
And the tremor usually appears when moving and standing.
Idiopathic tremor is thought to be caused by a disruption in the normal functions of parts of the central nervous
system such as the cerebellum.
With the mechanism of this occurrence unknown until now.
Scientists have not been able to determine an appropriate treatment for the disease because of a lack of
understanding of the main cause of this type of Flicker.
And it has not been revealed whether the disorder is also degenerative, and it is worth noting that it is difficult for the
affected person to control the tremor during its occurrence.
And its frequency usually increases with movement, and this type of tremor is common in children.
Dystonia is a type of uncontrolled and painful muscle contractions in some cases.
And dystonia is accompanied by excessive muscle movement, abnormal body postures, and a series of undesirable
and sequential movements, and these symptoms are all caused by the transmission of the brain False nerve signals,
which may affect any muscle of the body.
And this disorder is more common in young people, knowing that dystonia may be genetic in some cases.
Neurological disorders one of causes of tremors in the hands
There are a number of nervous disorders that can cause tremors in the hands, some of which are listed below:
- Multiple sclerosis (MS): Also known as multiple sclerosis, MS is an abbreviation for multiple sclerosis.
It is a chronic central nervous system disorder caused by the immune system attacking the nerve fibres as well as the
fatty layer surrounding the nerves and responsible for separating them.
Known as the myelin sheath in the brain and spinal cord.
In many cases, multiple sclerosis is accompanied by an uncontrollable tremor.
It can found in various parts of the body such as the head, arms, hands, and legs.
- Stroke: A stroke is the blockage of one of the arteries supplying one part of the brain as a result of the formation of a
blood clot, which leads to a lack of blood perfusion from the affected part of the brain and may cause permanent
damage to some nerves in the brain, resulting in shivering.
- TBI (traumatic brain injury) This occurs as a result of a physical injury that causes damage to the nerves responsible for
coordinating body movement.
And if certain nerves in the hands damaged, this results in hand tremors.
- Parkinson’s disease is a degenerative nerve disease that affects movement.
The disease occurs as a result of damage to the brain cells responsible for movement, resulting in difficulty with
balance, stiffness in the legs and arms.
And slow movement in the advanced stages of the disease.
The symptoms of the disease typically begin with a tremor in one hand, then progress to the other hand over time,
and the rest of the symptoms of the disease appear.
There are numerous causes and other health issues that can result in hand tremors, some of which are listed below:
- Some mental disorders such as depression.
- Degenerative disorders that are inherited.
Many body functions, including movement, balance, breathing, speaking, and heart function.
Can affected by neurodegenerative diseases.
- Carbon monoxide intoxication.
- Some types of infections, such as the acquired immunodeficiency virus, which known as AIDS.
- Liver or kidney failure.
- Nervous outbursts.
- Addiction to alcohol Hand tremors can appear as a withdrawal symptom during addiction treatment.
- Some types of tumors.
- Vitamin B12 deficiency.
- Vitamin B1 deficiency.
- Wilson’s disease is a genetic disorder in which the affected person suffers from an excess of copper in the body.
- One of the causes of action tremors is a tremor that occurs only while writing.
- Neurological disorders that affect the peripheral nerves that control movement.
Reasons to see a doctor
If tremor affects daily activities or a person’s life, it is important to see a doctor.
And it is critical to go to a medical
emergency as soon as possible if any of the following symptoms appear in conjunction with tremor of the hands:
- Breathing difficulty.
- difficulty walking
- Mental confusion or loss of consciousness, even if only for a short time.
- Difficulty speaking, such as slurred speech, or inability to understand what others are saying.
- Having a head injury.
- Vision changes or loss of vision.
- Stem hardening.
- Feeling weak or losing energy.
- Flickering confined to one side of the body.
- A rapid, non-spontaneous movement of the eyes known as nystagmus.
Hand tremor is one of the disorders that can have an impact on a person’s life and ability to complete daily tasks.
It is important to note that hand tremor can be caused by an unknown cause in some cases.
Or it can be caused by some motor or neurological health disorders.
Trembling hands are common; in some cases, trembling hands may be an early sign of degenerative disorders such as Parkinson’s disease.
