Understanding Tremors: What You Need to Know

Tremors are one of the most common neurological symptoms, yet they’re often misunderstood, overlooked, or dismissed as just “shaky hands.” At Charis Neurology, we believe that no symptom is too small to explore—especially when it begins to interfere with daily life. Tremors can range from mildly inconvenient to profoundly disabling, and understanding their cause is the first step toward relief.

What Is a Tremor?

A tremor is an involuntary, rhythmic muscle contraction that leads to shaking or oscillating movements in one or more parts of the body. Most commonly, tremors affect the hands, but they can also occur in the arms, head, voice, legs, or trunk.

Tremors are a symptom, not a disease in themselves. They can be isolated or part of a broader neurological condition.

Types of Tremors

There are several types of tremors, each with distinct causes and characteristics:

Essential Tremor (ET)

• The most common type of pathological tremor.

• Usually affects both hands and arms during movement or when holding a posture (e.g., holding a cup).

• Often runs in families.

• May worsen with stress, caffeine, or fatigue.

• Alcohol may temporarily improve the tremor in some cases.

Parkinsonian Tremor

• Typically a resting tremor (present when the limb is at rest and diminishes with movement).

• Often begins on one side of the body.

• Associated with other symptoms of Parkinson’s disease, including stiffness and slowness of movement.

Cerebellar Tremor

• Associated with damage to the cerebellum (balance center of the brain).

• Appears during targeted movement (e.g., reaching for something) and may worsen as the hand gets closer to the target.

Dystonic Tremor

• Occurs in individuals with dystonia, a movement disorder causing abnormal postures.

• Often irregular and may be task-specific.

Physiologic Tremor

• Occurs in healthy individuals, often enhanced by stress, fatigue, anxiety, caffeine, or certain medications.

• Usually very mild and not functionally limiting.

When Should You See a Neurologist?

Not all tremors require treatment, but if your tremor is:

• Worsening over time

• Interfering with daily tasks like writing, eating, or using devices

• Present with other neurological symptoms (e.g., balance issues, memory changes, weakness)

• Associated with a family history of neurological disease

…it’s time to get evaluated.

Diagnosis: How We Investigate Tremors

At Charis Neurology, we take a comprehensive approach, which may include:

• Detailed clinical history and neurologic exam

• EEG (if spells or episodes raise suspicion for seizures)

• MRI brain to rule out structural causes

• Nerve conduction studies if sensory symptoms are present

• Blood tests to assess thyroid function, metabolic conditions, or medication effects

Treatment Options

Treatment depends on the type of tremor and its impact on your life. Options may include:

• Medications such as beta-blockers (e.g., propranolol), primidone, or anti-anxiety agents

• Botulinum toxin (Botox) injections for focal tremors

• Physical or occupational therapy for functional improvement

• Lifestyle modifications, including caffeine reduction and stress management

• Surgical options like Deep Brain Stimulation (DBS), in severe cases
