Essential tremor, also known as benign tremor, is the most common movement disorder. It is generally bilateral, most commonly seen in the hands, and can also be accompanied by voice and head tremors. Unlike Parkinson's disease, it is a tremor that increases in severity during movement. It usually begins in middle and advanced age and gradually increases in severity over time.

Essential tremor is a neurological condition caused by the inability of the cerebellum, which controls muscle coordination, to communicate with other parts of the brain, resulting in involuntary shaking and rhythmic oscillation. It is known as one of the most common movement disorders. Tremor in both hands and arms during movement without neurological signs is a symptom of essential tremor.

Essential Tremor: The Truth Behind the Tremors

Essential tremor is a common neurological movement disorder that causes involuntary tremors. It usually starts in the hands, but can also affect the head, vocal cords and other parts of the body. Essential tremor can make daily activities difficult and significantly reduce quality of life. In this article, we will discuss the causes, symptoms, diagnosis and treatment options of essential tremor.

What are the Causes of Essential Tremor?

The exact cause of essential tremor is not fully understood, but research suggests that abnormalities in certain brain regions such as the cerebellum and brain stem may play a role. Genetic predisposition is also an important factor, and people with a family history are at higher risk of developing essential tremor. The most common causes include genetic predisposition, neurological conditions such as multiple sclerosis, Parkinson's disease, stroke, traumatic brain injury, diseases such as kidney failure and hyperthyroidism, as well as alcohol withdrawal, anxiety and panic.

Symptoms of Essential Tremor

• Tremor: The most prominent symptom is rhythmic tremors, usually seen in the hands. These tremors can occur during activity (action tremor) or at rest (resting tremor).
• Head Tremors: Some people may have involuntary movement of the head in a 'yes' or 'no' manner.
• Voice Tremors: When the vocal cords are affected, trembling or shakiness in the voice may occur.
• Walking Difficulty: Tremors in the legs can affect balance and coordination, making walking difficult.
• Psychological Effects: Essential tremor can lead to emotional problems such as embarrassment, anxiety and depression. (Difficulty writing or drawing.)

Diagnosis of Essential Tremor

The diagnosis of essential tremor is usually made with a detailed medical history, physical examination and neurological assessment. Your doctor will observe the characteristics of the tremors and may order tests to rule out other possible causes.

Tests that help rule out other diseases that may cause tremors are as follows:

• Blood tests
• Computed tomography
• Genetic testing
• Magnetic resonance imaging (MRI)
• Positron emission tomography (PET) and similar tests help rule out other conditions and confirm the diagnosis of essential tremor.

Essential Tremor Treatment Options

Treatment for essential tremor depends on the severity of the tremors, the person's age and overall health. People with mild tremors may not need any treatment. For more severe cases, the following options may be considered:

• Medication: Medications recommended by your doctors based on the severity of tremors can reduce symptoms. Certain beta-blockers, anti-seizure and sedative medications can slow down tremors.
• DBS (Deep Brain Stimulation): DBS surgery may be considered for severe tremors that do not respond to medication. In this procedure, electrodes are placed at specific targets in the brain and electrical stimuli are sent to control tremors.
• Botox Injections: Botox injections can be applied when the tremor is in the face or head.
• Surgical Procedures: Surgical procedures may be performed when tremors do not respond to medication or affect daily life.
• Physical Therapy: Physical therapy aims to strengthen the muscles to control tremors resulting from muscle spasms.

Deep Brain Stimulation (DBS)

DBS is an important treatment option for severe essential tremor cases that do not respond to medication. In this surgical procedure, electrodes are placed at specific targets in the brain and electrical stimuli are sent to control tremors. DBS can significantly reduce tremors and improve quality of life. However, like all surgical procedures, DBS has potential risks and side effects. Therefore, it is important to discuss DBS treatment in detail with your doctor before considering it.

Living with Essential Tremor

Essential tremor can be challenging, but with the right treatment and support, many people can manage their tremors and lead a fulfilling life. If you have concerns about essential tremor or want to learn more about treatment options, don't hesitate to talk to your doctor.

How Can Essential Tremor Be Prevented?

People with essential tremor and other tremor conditions can minimize symptoms by making some lifestyle changes. Not smoking, eating healthily, not consuming caffeinated beverages, staying away from stressful and tense environments, and doing breathing exercises help reduce symptoms.

Physical and speech therapy, eliminating or reducing caffeine, taking medications on time, getting adequate sleep, and paying attention to physical activity are all beneficial.
