Essential Tremor
Essential tremor is a neurological condition that causes involuntary, rhythmic shaking, most commonly in the hands. It often worsens during movement and may affect daily activities such as writing or holding objects. It is different from Parkinson’s disease.
🚨 Seek Urgent Medical Care
Get immediate help if tremor is accompanied by:
- Sudden weakness or paralysis.
- Difficulty speaking or facial drooping.
- Severe headache or confusion.
- Loss of balance or coordination.
- Rapid worsening of symptoms.
📞 Consult a Neurologist
Seek medical advice if:
- Tremors interfere with daily activities.
- Shaking gradually worsens over time.
- Family history of tremor or neurological disease.
- Uncertainty about the cause of shaking.
Common Symptoms & Causes
| Symptom | Possible Cause |
|---|---|
| Hand tremor during movement | Essential tremor |
| Head shaking | Neurological dysfunction |
| Voice tremor | Essential tremor affecting vocal cords |
| Difficulty writing or holding objects | Motor control impairment |
| Tremor worsens with stress | Physiological activation or anxiety |
Causes by Category
Familial tremor: Often inherited in families.
Gene mutations: Affect cerebellar function and motor control.
Cerebellar dysfunction: Impaired coordination of movement.
Aging brain changes: Natural degeneration of motor pathways.
Caffeine: May increase tremor severity.
Stress: Emotional stress worsens symptoms.
Fatigue: Lack of rest intensifies tremors.
Diagnostic Procedures
Neurological Examination
Assesses reflexes, coordination, and tremor pattern.
MRI Brain
Rules out structural brain abnormalities.
Blood Tests
Excludes metabolic or thyroid-related causes.
Tremor Analysis
Measures frequency and type of tremor.
