Tremor may be symptomatic of a large number of diseases, metabolic intoxications, toxins, drugs, and other states. These are outlined in Table 4 in the Introduction to Section 4 on ‘Tremor’. In most instances the features of the tremor have been covered in other chapters dealing with these disorders and these are also itemized in this table. No attempt is made here to reiterate all of this material and the reader is referred to the relevant chapters for further details. It should also be noted that rhythmic cortical myoclonus may masquerade as tremor, so-called cortical tremor (Ikeda et al. 1990; Toro et al. 1993; Guerrini et al. 1995) and this can sometimes be familial (Terada et al. 199 ). There may be grounds for classifying the disorder classically known as palatal myoclonus, which is described in Chapter 29, as a form of tremor. It has a relationship to Holmes’, cerebellar and certain post-traumatic tremors, which are described in this chapter. In addition to typical rest tremor, Parkinson’s disease can also be associated with a postural tremor of the outstretched hands, which is virtually indistinguishable from that seen in essential tremor. Such a postural tremor is also seen in a variety of other diseases of the nervous system, including dystonia and some peripheral neuropathies. Vice versa, rest tremor resembling parkinsonian tremor may also be present in other disorders including dystonia (Schneider SA et al. 2007).
