In the lively rhythm of Vietnamese life, subtle health changes can be missed. Yet, for many, involuntary shaking, known as essential tremor (ET), can deeply affect daily functioning and emotional health.
ET is the most common tremor disorder, marked by action tremors, shaking during voluntary movement or when holding a posture. It usually begins gradually and worsens over time. Most often affecting the arms and hands, it can also involve the head, voice or legs. Unlike Parkinson’s resting tremor, ET occurs during activity.
Daily challenges of ET
ET makes everyday tasks frustrating. Writing, eating, threading a needle, using a smartphone or holding a bowl of phở can become difficult. Many patients feel embarrassed or socially withdrawn. Stress, common in busy cities, often worsens symptoms.

What might contribute
Though the exact cause remains unknown, genetics plays a major role; up to 70 per cent of cases have a family history, especially with early onset. Other possible contributors include:
- Lifestyle: Caffeine, alcohol, smoking and some foods may worsen symptoms. Though small amounts of alcohol might temporarily help, it is not a long-term solution.
- Environmental exposures: Pesticides, solvents or heavy metals.
- Head trauma: Particularly in older adults.
Beyond the shaking
ET is more than a motor issue. It may involve:
- Cognitive issues: Problems with memory, focus or verbal fluency. Late-onset ET may carry an increased dementia risk.
- Mental health: Anxiety and depression are more common, along with fatigue and sleep problems.
ET vs Parkinson’s disease
People often confuse ET with Parkinson’s. Key differences include:

Diagnosis and management
Diagnosis of essential tremor is clinical, based on history, exam and family background.
Treatment aims to reduce disability and improve quality of life. Options include:
- Conservative care: Reduce stress, avoid triggers (e.g. caffeine) and use tools like weighted utensils or adaptive tech. Occupational and physical therapy are helpful.
- Medication: Propranolol and primidone are common first-line drugs. Others like topiramate, gabapentin or atenolol may help. Short-term medication can assist during stressful events.
- Advanced options: For severe cases, Deep Brain Stimulation (DBS) or MR-guided Focused Ultrasound (MRgFUS) may be offered. Some wearable nerve stimulators provide temporary relief. These interventions require thorough evaluation at specialised centres.
While research continues, personalised care helps people with ET live fulfilling lives. Seek professional advice early to explore the best path forward. Family Medical Practice
