HERNANDEZ MANDADO, Pedro  y  VELA VALENCIA, Teresa Idania. Differential diagnosis of tremor. AMC [online]. 2009, vol.13, n.4. ISSN 1025-0255.

A bibliographical revision of the tremor is made with emphasis in the criticism of the concept, the etiologic aspects and the semiology, as well as the semiotecnia; aspects these that contribute, among other, to clarify the differential diagnosis based on the anatomical localization, the accompanying behavioral circumstances, its extent and some entities or causal factors, elements that derive in facilitating a classification proposal with the corresponding semiotecnia. Finally it is insisted in the pathologies, toxic, drugs and genetic aspects that can originate this symptom-sign, as well as in a nosologic entity that tremor is a capital symptom and exceptionally it can happen with total absence (Parkinson) and to share to difficulties in the diagnosis. The necessity of studying this topic for its clinical and neuro - psychic importance as well as for its concise bibliography, is evidenced mainly recent.

Palabras clave : tremor; semiology; semiotecnia.
