Extractions: Causes, incidence, and risk factors: All people have some degree of tremor that occurs during movement,. This shaking is called physiologic (occurs normally), and it mainly involves the hands. Stressful circumstances, such as fatigue, anger, fear or using certain substances (such as coffee or cigarettes) may cause transient worsening of physiologic tremor, to the point that it may become visible to the naked eye. Essential tremor is the most common form of abnormal tremor, which resembles an exaggerated physiologic shaking. Essential tremor is worsened by the same factors that enhance physiologic tremor. Although the cause is unknown, new research shows that one part of the brain called cerebellum does not appear to function properly in patients who have essential tremor. The cerebellum is the part of the brain that coordinates muscle movements and therefore, provides accuracy and harmony to voluntary movement. Nevertheless, no evident brain lesions have been identified in patients with this form of tremor. There is evidence that there are several different types of essential tremor (such as young-onset essential tremor or essential tremor with head tremor). These types differ in their response to treatment.

Extractions: Two conditions make up the largest numbers of patients with movement disorders who might be suitable for radiosurgical treatment. These diseases are Parkinson's disease and essential tremor (familial tremor). In unusual circumstances, movement disorders may also be due to head injuries, brain infections such as encephalitis, or following strokes. Movement disorders take a wide variety of forms. One of the most common movement disorders is tremor. In Parkinson's disease, the tremor or shaking usually involves the arms and hands and is most prominent when the patient is at rest. In essential or familial tremor, the hands and arms are usually quiet at rest, but if the patient attempts to perform a task, such as picking up a glass of water or writing, then the tremor becomes very noticeable. Tremor can sometimes involve the head and neck and also sometimes involves the legs. Tremor interferes with many normal activities. Patients may be unable to write their name and, for instance, sign checks. They may be unable to drink from a cup or glass without spilling, and they may be unable to cut food with a knife and fork. In addition, patients may be unable to feed themselves, button clothing, comb their hair, or perform almost any movement that involves coordinated control of the hands, fingers and arms.

Chorea and Huntington's Disease Essential tremor is the most common movement disorder. It is often inherited as a familial trait but can occur sporadically as well. It occurs in 1-5% of people over 40 years old. Symptoms are limited to tremulous or shaking motions of the hands, arms, legs, trunk, head or voice. Typically, the involuntary motions are most prominent when performing certain activities such as writing or holding utensils. This disorder is often misdiagnosed as Parkinson's disease. However, unlike Parkinson's disease there are generally no tremors at rest and other neurological symptoms such as slowness, stiffness, imbalance and immobility do not occur. This disorder is commonly treated with medications which can provide substantial relief in many patients. For those patients who have disabling symptoms and do not respond to medications there are now surgical procedures available which have an excellent track record of safety and effectiveness.

Introduction & Symptoms essential tremor (ET) is a nerve disorder characterized by uncontrollable shaking, or tremors, in different parts and on different sides of the body. http://my.webmd.com/content/article/40/4021_105.htm
Extractions: Additional Resources What Is Essential Tremor (ET)? Essential tremor (ET) is a nerve disorder characterized by uncontrollable shaking, or "tremors", in different parts and on different sides of the body. Areas affected often include the hands, arms, head, larynx, or voice box (making the voice sound shaky), tongue, chin and other areas. Rarely, the lower body is affected. ET is not a life-threatening disorder, unless it prevents a patient from caring for him/herself. Most people are able to live normal lives with this condition although they may find everyday activities like eating, dressing or writing difficult, which leads them to withdraw socially. But it is only when the tremors become severe that they actually cause disability. Symptoms of Essential Tremor The term "tremor" is used to describe the uncontrollable shaking, but that's a symptom that can be caused by a multitude of different factors and diseases including Parkinson's disease, multiple sclerosis, fatigue after exercise, extreme emotional distress, brain tumors, some prescription drugs, metabolic abnormalities, and alcohol or drug withdrawal.

Sometimes tremor is a normal reaction to a situation such as fear, fatigue or anger. It also can be a side effect of too much caffeine, a medication or withdrawal from a drug or medicine. When tremor occurs during activities and there is no emotional or chemical cause, it can be a sign of a neurological disease called essential tremor.
FAQ Unlike EPT, essential tremor is a repetitive involuntary movement, which causes essential tremor can appear in more than one body part at the same time, http://www.tremoraction.org/02faq.html
Extractions: Physiologic tremor is defined as a normal action, present in both children and adults. Usually, the oscillating movement of any body part is hardly noticeable to the naked eye. Physiologic tremor is observable when enhanced by strenuous activity, exhaustion, stress, excitement or fear. Example of Enhanced Physiologic Tremor (EPT) Tyler Hamilton's hands trembled and shook after completing Stage 5 of the 2003 Tour de France. He needed both hands to lift a beverage to his lips. The American cyclist experienced EPT from riding 123 miles over hills. After fifteen minutes of rest, the twitching in his hands slowly dissipated, and Tyler Hamilton gingerly signed autographs for his fans. What is Essential Tremor? Unlike EPT, essential tremor is a repetitive involuntary movement, which causes parts of the body (hands, arms, head, voice) to tremor, even in the absence of the physiological activity that enhanced Tyler Hamilton's hands to tremble. Essential tremor can appear in more than one body part at the same time, marked by bilateral symmetry. Essential tremor is a chronic, progressive neurological disorder that can occur at any age, including birth. Essential tremor does not discriminate. Males and females are affected equally.

Extractions: SECTION 3 Medical Conditions CHAPTER 30 Movement Disorders TOPICS Introduction Myoclonus Dystonia Tardive Dyskinesia and Akathisia ~ Essential Tremor ~ Parkinson's Disease Progressive Supranuclear Palsy Shy-Drager Syndrome A tremor is unintentional, rhythmic shaking or trembling. Essential tremor is a tremor whose cause is unknown. However, some evidence suggests the cause could be an abnormality of the cerebellum. This tremor, once called benign or senile tremor, affects up to 1 out of 5 people over 65. The tremor often begins in young adulthood and slowly becomes more obvious as people age. However, the tremor may begin much later in life. Some forms of essential tremor run in families and are sometimes called familial tremor. In many people, essential tremor remains mild, although it may be troublesome and embarrassing. However, the tremor often gradually worsens over time, eventually resulting in disability. Essential tremor affects the arms most often and the legs rarely. Because it occurs during movement, such as writing or using eating utensils, it is considered an action tremor. Essential tremor also occurs when the limbs are held out from the side. The tremor usually stops when the arms or legs are at rest. Usually, essential tremor affects both sides of the body, but one side is affected more than the other.

Everyone has a tremor to some degree. For example, when held outstretched, the hands usually tremble slightly in most people. Such slight, rapid tremor is normal and reflects the precise moment-by-moment control of muscles by nerves. In most people, the tremor is too slight to be noticed. Factors that can make the tremor more noticeable include stress, anxiety, fatigue, alcohol withdrawal, an overactive thyroid gland (hyperthyroidism), consumption of caffeine, and use of drugs that are stimulants (such as ephedrine).

But it's more likely your shakiness is a sign of a movement disorder called essential tremor. Although essential tremor can affect almost any part of your body, trembling occurs most often in your hands, especially when you try to do simple tasks such as drinking a glass of water, tying your shoelaces, writing or shaving. Sometimes, you may also have trembling in your head, voice or arms. Essential tremor is the most common of the many movement disorders, affecting as many as 5 million Americans, most of them age 60 or older. It's far more common than Parkinson's disease, with which it may sometimes be confused. Unlike Parkinson's disease, however, essential tremor doesn't lead to serious complications. In fact, the word essential in essential tremor means the disorder isn't linked to other diseases.
Essential Tremor Q I am 69 years of age and have been diagnosed with essential tremor. A essential tremor is also known as familial tremor, because it often occurs http://healthlink.mcw.edu/article/901214105.html
Extractions: Subscribe now >> Q: I am 69 years of age and have been diagnosed with "Essential Tremor." The shaking I have is in my head and the doctor has put me on the drug Mysoline. At times I feel okay, and other times it seems as if I'm tightened up in my neck and feel myself shaking. Other times I don't feel it. In fact, my husband is the one who noticed it at first and said it was shaking a lot. Could you tell me if there is a known cause for this and if there is any other medication available? I have heard this is what Katherine Hepburn has and more women have this. What is the prognosis of this affliction? A: Essential tremor is also known as "familial tremor," because it often occurs in several members of the family. About half of the cases are directly inherited, and the other half arise spontaneously. The head and hands are often affected, and even the voice may be involved (Katherine Hepburn is a good example of that). Although the tremor may start at any age, it usually begins in young adulthood and persists throughout life. Obviously this can be quite embarrassing, since it may look like the person is very nervous because of the shaking. It is not more common in women than men and does not necessarily get worse with age. One or two drinks of alcohol may eliminate the tremor briefly, but it will become worse after the alcohol has worn off. There are a few treatment options you could try. Propranolol is a heart/blood pressure medicine that will decrease the tremor in some people, especially if it is a fast fine tremor with a frequency of about 8 shakes per second. Mysoline, which your doctor prescribed, is probably the drug of choice. A dose of 50 mg can be taken at bedtime and increased gradually up to 250 mg if necessary.
