Understanding the causes and symptoms of essential tremor

A tremor in your hands can be alarming, but understanding the cause is key. Don't miss this clear, expert guide to Essential Tremor, a common movement disorder. Learn how to identify and manage the symptoms effectively.

What are the main causes of Essential Tremor?

• The exact cause of essential tremor is not fully understood, but it is considered a neurological disorder affecting the cerebellum and its connections.
• There is a strong genetic component, as about half of all cases are inherited from a parent through an autosomal dominant inheritance pattern.
• Unlike tremors from other conditions, it is not caused by another disease, though its symptoms can be worsened by stress, fatigue, or caffeine.

Key symptoms of Essential Tremor to watch for

• The primary symptom is an involuntary, rhythmic shaking, most often a tremor in hands that occurs during voluntary movements like writing or drinking.
• The tremor may also affect the head, voice, arms, or legs, and typically occurs on both sides of the body, though one side may be worse.
• A key aspect of essential tremor vs Parkinson's is that the shaking happens during action, not typically when the muscles are at rest.

How is Essential Tremor managed and treated?

• While there is no cure, essential tremor treatment focuses on managing symptoms, often with medications like beta-blockers, such as propranolol, or anti-seizure drugs.
• Physical and occupational therapy can help improve muscle control, coordination, and function, making daily tasks easier to perform for many patients.
• For severe cases that do not respond to medication, more advanced treatments like deep brain stimulation (DBS) or focused ultrasound may be considered.
