A working diagnosis is made from a neurological examination and evaluation. Parts of a complete examination include a physical examination, MRI, patient history, and electrophysiological and accelerometric studies. A diagnosis of solely intention tremor can only be made if the tremor is of low frequency (below 5 Hz) and without the presence of any resting tremors. Electrophysiological studies can be useful in determining frequency of the tremor, and accelerometric studies quantify tremor amplitude. MRI is used to locate damage to and degradation of the cerebellum that may be causing the intention tremor. Focal lesions such as neoplasms, tumors, hemorrhages, demyelination, or other damage may be causing dysfunction of the cerebellum and correspondingly the intention tremor.
