We also highlight some of the controversies in the field of tremor, and share our perspectives for the future research. The major objective of this article is to provide an updated review of various tremor syndromes with special reference to the new bi-axial classification system. Since tremor has a vastly heterogeneous etiological spectrum, it is important to fully appreciate the phenomenology of tremor in various tremor syndromes and other neurological features associated with those syndromes. The publication engendered a great deal of controversy about the definition of ET and related syndromes.

One of the major aims was to redefine ET (“bilateral upper limb action tremor” of “at least 3 years' duration”) and to introduce the concept of ET plus (ET with additional neurologic soft signs such as dystonia, ataxia, parkinsonism) ( 1). The task force on tremor of the International Parkinson and Movement Disorders Society (IPMDS) proposed a classification scheme based on two axes axis 1- emphasizing the clinical features, history, and tremor characteristics and axis 2- emphasizing the potential etiologies of tremor ( 1). Tremor can be an isolated manifestation of a disease such as essential tremor (ET) or it can be a part of other neurological disorders.

After leg stereotypy syndrome ( 3), tremor is the most commonly observed movement disorder in adults ( 4, 5). Tremor is an involuntary, rhythmic, and oscillatory movement which may involve one or several body parts ( 1, 2). In this article, we discuss the key aspects of the new classification, review various tremor syndromes, highlight some of the controversies in the field of tremor, and share the potential future perspectives. based on the clinical features, history, and tremor characteristics and 2. The new classification is based on two axes: 1. This system has remained a prime topic of scientific communications on tremor in recent times. The tremor task force of the International Parkinson Disease and Movement Disorders Society has worked toward this goal and proposed a new classification system. Considering the marked etiological and phenomenological heterogeneity, it would be desirable to develop a classification of tremors that reflects their underlying pathophysiology. A wide range of pathologies may manifest with tremor either as a presenting or predominant symptom.

Tremor is the most commonly encountered movement disorder in clinical practice.
