Practical clinical algorithm. Isolated tremor syndromes are depicted in blue on the left side of the diagram, combined tremor syndromes in orange on the right side. Functional tremor is depicted in green on the right side. *For example, mildly unsteady tandem gait, questionably abnormal posturing of a body part, mild cognitive impairment, questionable bradykinesia or rigidity and other mild neurological signs of unknown significance that do not suffice to make an additional syndrome classification or diagnosis. †For example, anxiety, fatigue, thyrotoxicosis, hypoglycaemia, pheochromocytoma, tremor-provoking medication (see table 1).
