Tremors can also be caused by conditions or medicines that affect the nervous system, including Parkinson's disease, liver failure, alcoholism, mercury or arsenic poisoning, lithium, and certain antidepressants.
Several factors aid clinicians in the diagnosis of drug-induced tremor: (1) exclusion of other medical causes of tremor (eg, hyperthyroidism, hypoglycaemia); (2) a temporal relation to the start of therapy with the drug; (3) a dose-response relation (ie, increasing the drug dose worsens the tremor, or decreasing the dose ameliorates the tremor); and (4) lack of tremor progression, unlike tremors in Parkinson's disease and essential tremor.
