What is Essential Tremor?
Essential Tremor (ET) is one of the most common neurological movement disorders worldwide. It typically causes involuntary shaking in the hands, and sometimes the head or voice.
Assoc. Prof. Dr. Mehmet Sorar approaches this condition not only as a neurological disorder but also as a factor that affects social identity, quality of life, and personal freedom. This guide explores the anatomy of tremors, the fine line separating ET from Parkinson’s, and the diagnostic process—without getting lost in complex medical jargon.
The Anatomy of Essential Tremor: Why Do We Shake?
Normally, the brain sends perfectly synchronized signals to muscles. Think of the body as an orchestra, where the cerebellum and thalamus act as conductors. In ET, a minor “short circuit” in these circuits disrupts harmony, resulting in involuntary, uncontrollable shaking.
The hallmark of ET is kinetic tremor, which appears during movement. Your hands may be still when resting, but as soon as you try to lift a cup or use a spoon, tremor kicks in—attacking you at your most vulnerable moments.
Genetics plays a role in about 50% of cases, though it can also occur sporadically.
The Hidden Impact of Tremor
Simple daily tasks like drinking coffee without spilling, buttoning a shirt, or signing documents can feel like a repeated challenge. Though ET is medically considered “benign,” its social and psychological effects are far from harmless. Patients may withdraw, avoid social settings, and feel constantly observed.
Dr. Sorar’s treatment philosophy is not only to stop shaking hands but also to help patients break free from this social isolation.
Essential Tremor vs. Parkinson’s Disease
Many patients fear Parkinson’s when they first notice tremors. Although both conditions involve shaking, they differ in origin, progression, and treatment.
1. Tremor Timing
- Parkinson: Tremor often starts subtly at rest (“resting tremor”). Movement can reduce it.
- Essential Tremor: Tremor appears during action, worsening as you reach your target.
2. Accompanying Symptoms
- Parkinson: Bradykinesia (slowness), facial stiffness, stooped posture, shuffling steps, and cogwheel rigidity. Progressive and potentially disabling.
- Essential Tremor: Usually monosymptomatic—only tremor. Walking, balance, and cognition remain normal.
3. Alcohol Response
- Small amounts of alcohol can temporarily reduce ET tremors, a feature not seen with Parkinson’s tremor. (Diagnostic clue, not a treatment recommendation.)
Diagnosis Process
There’s no single test or MRI to confirm ET. Diagnosis relies on:
Clinical History and Examination
Dr. Sorar evaluates onset, triggers (stress, caffeine, fatigue, fasting), and family history.
Tests include:
- Extending arms forward
- Finger-to-nose test
- Bringing both hands together
- Drawing spirals (ET patients produce irregular, jagged lines; Parkinson patients draw small, faint spirals)
Imaging
MRI is usually normal. Its purpose is to rule out tumors, MS lesions, stroke, or other structural causes. Blood tests may check thyroid function, B12 deficiency, or medication side effects.
Frequently Asked Questions (FAQ)
Q: Does essential tremor worsen over time?
A: Yes, ET progresses slowly. Tremor can spread to the other hand, head, or voice, but it’s not as rapid or destructive as Parkinson’s and does not shorten life expectancy.
Q: Does stress worsen tremors?
A: Absolutely. Stress, excitement, fatigue, excessive caffeine, or low blood sugar can significantly amplify tremor.
Q: Can children get ET?
A: Usually seen in adults over 40, but genetically predisposed individuals may start in adolescence or young adulthood.
Q: Can medication cure ET?
A: No. Medications only suppress symptoms. Tremors return once the drug wears off, and tolerance may develop over time.
