Essential Tremors - Causes, Treatment & When to See a Doctor

What is Essential Tremors?

Essential tremors

Common Causes

Essential tremors are typically idiopathic, meaning the exact cause is unknown. However, certain factors or underlying conditions may contribute to their development or mimic essential tremor symptoms. Below are 10 conditions or factors associated with tremors:

• Genetic factors: Essential tremors often run in families. A genetic predisposition may increase risk, although specific genes are still under study (Mayo Clinic, 2023).
• Age: Most people develop essential tremors between ages 40–60, though cases in younger or older adults exist.
• Parkinson’s disease: Early Parkinson’s may present with tremors, but these are usually at rest and asymmetrical (NIH, 2022).
• Multiple sclerosis: Tremors can occur due to nerve damage from the disease (National MS Society, 2021).
• Essential tremor: Often confused with other tremors, but characterized by action tremors (worsening with movement).
• Alcohol withdrawal: Tremors can occur during detoxification but are typically accompanied by other symptoms (CDC, 2020).
• Thyroid dysfunction: Hyperthyroidism (overactive thyroid) may cause tremors and muscle twitching (Endocrine Society, 2023).
• Brain injuries: Trauma or stroke affecting the cerebellum can lead to tremors (Cleveland Clinic, 2022).
• Medications: Certain drugs, including some anti-seizure or psychiatric medications, may induce tremors as a side effect (NIH, 2023).
• Stroke: A stroke impacting motor control areas of the brain may result in tremors (WHO, 2021).
• Anxiety or stress: While not a direct cause, stress can exacerbate tremor severity (Mayo Clinic, 2023).

It’s important to consult a doctor to differentiate essential tremors from other conditions with similar symptoms.

Associated Symptoms

Essential tremors are most noticeable in the hands, but they can affect other areas. Common associated symptoms include:

• Action-dependent tremors: Shaking worsens during purposeful movement (e.g., holding a cup).
• Facial or head tremors: Less common but may cause drooling or difficulty eating.
• Choking or spilling: Tremors during drinking or eating can lead to accidents.
• Fatigue: Tremors may intensify after prolonged physical activity.
• Psychological impact: Anxiety or frustration from managing tremors.
• Normal cognition: Essential tremors rarely affect memory, speech, or thinking (NHS, 2023).

If tremors interfere with daily activities, medical evaluation is recommended.

When to See a Doctor

Seek medical advice if:

• Tremors start suddenly or worsen rapidly.
• You experience additional symptoms like speech difficulty, balance issues, or vision changes.
• Tremors interfere with work, self-care, or sleep.
• You suspect tremors are linked to a new medication or illness.

Early diagnosis helps rule out conditions like Parkinson’s disease or neurological disorders.

Diagnosis

Diagnosing essential tremors involves clinical evaluation and ruling out other causes. Doctors may:

1. Review medical history and family history of movement disorders.
2. Conduct a physical exam to observe tremor patterns (action vs. resting).
3. Order blood tests to check thyroid or metabolic issues.
4. Use imaging (MRI or CT) to exclude brain abnormalities.
5. Perform assessments like the finger-nostril sign (rapidly touching finger to nostril).

Essential tremors are diagnosed based on symptom patterns, typically after excluding other conditions (Mayo Clinic, 2023).

Treatment Options

Treatment varies by severity. Options include:

Medical Treatments

• Beta-blockers: Propranolol or nadolol to reduce tremor severity (UpToDate, 2023).
• Anticonvulsants: Primidone may help in some cases.
• Carbonic anhydrase inhibitors: Such as topiramate for moderate tremors.
• Deep brain stimulation (DBS): Surgical option for severe tremors unresponsive to medication (NIH, 2022).

Home and Lifestyle Management

• Reduce caffeine and alcohol intake.
• Practice stress-reduction techniques like yoga or meditation.
• Use adaptive tools (weighted utensils, braces) for daily tasks.
• Keep a tremor diary to track triggers and severity.

Always discuss treatment options with a neurologist (Cleveland Clinic, 2022).

Prevention Tips

While essential tremors can’t be entirely prevented, managing risk factors may help:

• Maintain a healthy lifestyle: Regular exercise and balanced diet
• Avoid excessive caffeine or nicotine
• Monitor thyroid health with annual blood tests
• Manage stress proactively

Genetic counseling may be recommended for those with a family history (Mayo Clinic, 2023).

Emergency Warning Signs

Contact a healthcare provider immediately if you experience:

• Sudden, severe tremors accompanied by seizures or loss of consciousness
• Tremors affecting breathing, swallowing, or speech
• Tremors following a head injury or stroke

These symptoms could indicate emergencies like hypoglycemia, brain hemorrhage, or neuroleptic malignant syndrome (CDC, 2020).

Essential tremors are manageable with proper care. Always consult a healthcare professional for personalized advice.
