Epidemiology and differential diagnosis of tremor

Abstract

Tremor are involuntary, rhythmic, oscillatory movements of a body part. The diagnosis of tremor is based on clinical information obtained from the history and physical examination. The most common types are enhanced physiological tremor, essential tremor, and parkinsonian tremor. The first step in evaluating a patient with a tremor is to classify the tremor based on its activation state, topographic distribution, and frequency. We analyzed the medical records of 99 patients who applied with complaints of tremor to the Regional Clinical Hospital, which showed that the most common diagnoses in patients with tremor were Parkinson's disease (44.4 %) and essential tremor (15.1 %).
