Approach to a tremor patient.

Area of Science:

• Neurology
• Movement Disorders

Background:

• Tremors are prevalent, representing the most common movement disorders.
• Defined as rhythmic, involuntary oscillatory movements around joints, tremors vary in etiology and clinical presentation.

Purpose of the Study:

• To review the classification, diagnosis, and treatment of various tremor types.
• To highlight the importance of accurate classification for identifying underlying causes.

Main Methods:

• Clinical classification based on rest or action, frequency, amplitude, and body part involved.
• Review of common tremor etiologies including Parkinsonian, Essential Tremor (ET), and psychogenic tremors.
• Assessment methods including clinical rating scales and electrophysiological measurements.

Main Results:

• Parkinsonian tremor is a common cause of rest tremor; Essential Tremor (ET) and enhanced physiological tremor are common action tremors.
• Isolated head tremor may indicate dystonia, while isolated voice tremor might be part of the ET spectrum.
• Psychogenic tremor diagnosis requires specific clinical signs, not exclusion.

Conclusions:

• Accurate tremor classification is crucial for etiological diagnosis.
• Treatment is symptomatic, with medications effective for some Essential Tremor cases; deep brain stimulation and botulinum toxin injections are alternative therapies for refractory or specific tremor types.
