Essential tremor is the most common trembling disorder. Caffeine intake and fatigue are often exacerbating factors in essential tremor with few alleviating factors. They can mimic organic movement disorders, such as tremor, dystonia, myoclonus, parkinsonism, tics and paroxysmal dyskinesias. Die Tremor-Forschung an der Neurologischen Universitätsklinik Freiburg befasst sich mit den Netzwerken im Gehirn, die den Tremor verursachen. Dozens of medications can cause or exacerbate any type of tremor (Table 2).18 Patients with new-onset tremor should have a comprehensive medication review with specific attention to any medications started before the onset of tremor.8 Medications that stimulate the sympathetic nervous system (e.g., amphetamines, terbutaline, pseudoephedrine) and psychoactive medications (e.g., tricyclic antidepressants, haloperidol, fluoxetine [Prozac]) are most likely to cause a postural tremor.1,8,12,13 When the medication review reveals a likely culprit, a trial discontinuation should be attempted if clinically possible.

Most tremors can’t be easily treated, but they’ll often go away on their own. They occur at a frequency of 3 to 6 cycles/seconds (hertz [Hz]). Associated conditions and diseases should be identified. Essential tremor has been described as postural, kinetic, and even as a sporadic resting tremor.3,12 One study found that 95% of patients with essential tremor had primarily kinetic, rather than postural, characteristics.12 Essential tremor is most obvious in the wrists and hands when patients hold their arms in front of them; however, it can also affect the head, lower extremities, and voice.13 It is generally bilateral, is present with different tasks, and interferes with activities of daily living.1,5, Essential tremor affects 0.4% to 6% of the population.4 In about one-half of cases, it is transmitted in an autosomal-dominant fashion.8 Although essential tremor can manifest by early adulthood, most patients do not present for treatment until 60 to 69 years of age because it tends to progress slowly. The features and causes of metabolic tremor are varied.8 Initial workup of tremor may include blood testing for hepatic encephalopathy (e.g., ammonia level), hypocalcemia, hypoglycemia, hyponatremia, hypomagnesemia, hyperthyroidism, hyperparathyroidism, and vitamin B12 deficiency.8. Maintaining different volitional movement frequencies simultaneously in two different body parts is difficult. Sometimes tremor is a familial condition (eg, essential tremor). Although these techniques are widely available, they should be used only after reasonable drug therapy has failed and only in patients who do not have substantial cognitive or psychiatric impairment. The unsteadiness stops when you: A physiologic tremor affects the hands and fingers but isn’t typically noticeable to the naked eye. Tremors that affect speech cause a quiet shakiness of the voice. Measurement of serum ceruloplasmin level and 24-hour urinary copper excretion should be considered in young patients presenting with tremor to exclude this potentially life-threatening disease.16,22 A video example of this tremor is available at http://www.youtube.com/watch?v=JgDvQUwUOo0.

Psychogenic tremor can be identified because psychogenic tremors decrease or disappear when the patient is mentally distracted and when tremor frequency synchronizes (entrains) to a volitional tapping rhythm by an unaffected body part. Sudden onset of tremor is more likely to be caused by medication use, toxins, a psychogenic cause, or, in rare cases, a brain tumor. Tremor.

Many older patients attribute development of tremor to normal aging and may not seek medical attention. Noncontrast magnetic resonance imaging and computed tomography can rule out secondary causes of tremor (e.g., multiple sclerosis, mass lesion, stroke) when the history and physical examination are suggestive of a structural cause, or in parkinsonism with atypical features or that is refractory to levodopa.28, If there is diagnostic uncertainty, single-photon emission computed tomography (SPECT) using ioflupane (123I-FP-CIT SPECT or DaTSCAN), in addition to subspecialty consultation, can be useful for distinguishing Parkinson disease from essential tremor, and to a lesser extent from drug-induced tremor, dystonic tremor, psychogenic tremor, or unilateral postural tremor.29,30 When assessing for dopamine transporter dysfunction, 123I-FP-CIT SPECT was 78% sensitive and 97% specific, with a positive likelihood ratio of 26 and a negative likelihood ratio of 0.23 in one case series of 99 patients with suspected Parkinson disease.31 A positive test can therefore rule in a diagnosis of Parkinson disease within three years; however, it is not superior to clinical assessment in the diagnosis of Parkinson disease,29 and its specific clinical use remains unclear.32, Transcranial ultrasonography can also predict Parkinson disease by revealing hyperechogenicity of the substantia nigra.
