Diagnosis is clinical. Treatment depends on the cause and type of tremor and may involve avoidance of triggers (physiologic), propranolol or primidone (essential), physical therapy (cerebellar), levodopa (parkinsonian), and possibly deep brain stimulation or thalamotomy (disabling and drug-refractory). The severity of tremor may not be related to the seriousness of the underlying disorder. For example, essential tremor is generally thought of as benign and should not shorten life, but symptoms can be disabling, and cerebellar degeneration has been detected in some neuropathologic studies. Pathophysiology of Tremor Various lesions in the brain stem, extrapyramidal system, or cerebellum can cause tremors. Neural dysfunction or lesions that cause tremor may result from injury, ischemia, metabolic abnormalities, or a neurodegenerative disorder. Sometimes tremor is a familial condition (eg, essential tremor). Classification Postural tremors are maximal when a limb is maintained in a fixed position against gravity...

Diagnosis Diagnosing essential tremor involves a review of your medical history, family history and symptoms and a physical examination. There are no medical tests to diagnose essential tremor. Diagnosing it is often a matter of ruling out other conditions that could be causing symptoms. To do this, your health care provider may suggest the following tests. Neurological examination In a neurological examination, your health care provider tests your nervous system functioning, including checking your: • Tendon reflexes. • Muscle strength and tone. • Ability to feel certain sensations. • Posture and coordination. • Gait. Laboratory tests Blood and urine may be tested for several factors, including: • Thyroid disease. • Metabolic problems. • Medicine side effects. • Levels of chemicals that may cause tremor. Performance tests Essential tremor test One test used to evaluate essential tremor involves drawing a spiral. The spiral on the left was drawn by someone affected by essential tremor. The spiral on the right was drawn by a person not affected by essential tremor. To evaluate the tremor itself, your health care provider may ask you to: • Drink from a glass. • Hold your arms outstretched. • Write. • Draw a spiral. A health care provider who still is not sure if a tremor is essential tremor or Parkinson's disease might order a dopamine transporter scan. This scan can help the provider tell the difference between the two types of tremor. Treatment Some people with essential t...

• Resting tremor: A tremor which is present at rest • Action tremor: A tremor which appears when a body part is being moved • Intention tremor: An intention tremor also occurs with movement but worsens when you get close to a target • Kinetic tremor: A tremor which occurs during voluntary movement • Task-specific tremors: Tremors which occur only with specific actions • Isometric tremor: A tremor which occurs when a body part is not moving but the muscles are tensed. The example often used is having your arms shake during push-ups when your position is held. • Postural tremor: A tremor which occurs when a body part is held against gravity (holding your arms straight out in front of you) Physiologic Tremor Everyone has a physiologic tremor, although it usually isn’t very noticeable. This is the tremor you may have noticed when you hold your hand out with fingers extended. It may become more noticeable (thereby becoming an “enhanced physiological tremor”) due to anxiety, fatigue, stimulants like caffeine, fever, alcohol withdrawal, low blood sugar, some medications, and more. Enhanced physiological tremor goes away when the underlying cause is corrected. Essential Tremor This tremor progresses very slowly and usually increases with age, affecting in particular people over the age of 60. The hands are usually most affected. The tremor is an action tremor, meaning that it is most prominent whenever someone tries to use their hands to do something. Since the tremor occurs when ...
