most common form of abnormal tremor, resembles an exaggerated shaking, essential tremor is worsened by the same factors that enhance normal tremors, new research shows that one part, the brain, the cerebellum, does not appear to function properly in patients, essential tremor, cerebellum, the brain that coordinates muscle movements, provides accuracy, harmony to voluntary movement, no brain lesions have been identified in patients, form of tremor, evidence of several different types of essential tremor, young-onset essential tremor, essential tremor, head tremor, types differ in response to treatment, an essential tremor occurs in more than one member of a family, a familial tremor, appears that essential tremor has some genetic basis, not only, the hereditary pattern observed, families, an identical twin, who shares the same genes, essential tremor is twice, likely, a fraternal twin, who has different genes, to have essential tremor, identical twins, not share this condition, environmental factors must play a role, essential tremors, occur at any age but, most common in people older than 65, essential tremor, relatively benign condition, affecting movement, voice quality, no other effects, rhythmic, moderately rapid tremor of voluntary muscles, purposeful movements, make the tremors worse, avoiding hand movements, suppress the tremors completely, difficulty holding, using small objects, silverware, writing utensils, over time, tremors, affect the hands, arms, head, voice box, eyelids, muscles, an essential tremor rarely involves, legs, feet, start in one body part but, progress to, parts, tremors, occasional, sporadic, temporary, episodic, occurring at intervals, intermittent, occur at a rate of, 6 to 10 oscillations per second, affect the head, hands, arms, eyelids, voice, less commonly affect the legs, feet, not affect both sides, the body equally, voluntary movement, emotional stress, disappear, sleep, improve, alcohol, no diagnostic laboratory test, essential tremor, diagnosis, the patient's history, a physical examination revealing tremor on voluntary movement, no other abnormalities, testing, rule out other causes, tremors, excessive caffeine, tobacco use, alcohol withdrawal, use of certain medications, asthma drugs, antidepressants, lithium, anti-seizure drugs, hyperthyroidism, pheochromocytoma, wilson's disease, a rare condition, copper accumulates, in the brain, liver, disorders, routine laboratory tests, brain imaging studies, ct scan, the head, brain mri, x-rays, tests, normal, not routinely performed, tremors interfere, the patient's ability to perform daily activities, considered embarrassing, medications result in symptom improvement in most patients, one out of four patients, not benefit from treatment, two medications, considered the first line of therapy, propranolol, primidone, propranolol blocks the action of stimulant substances, neurotransmitters, particularly compounds related to adrenaline, primidone, anti-seizure medication, modulates the function, neurotransmitters, medications, considered equally efficacious, have significant side effects, side effects of propanolol, fatigue, shortness of breath, asthma should not use this drug, slowing, the heart rhythm, nose stuffiness, problems associated, primidone, drowsiness, difficulty concentrating, nausea, poor gait, walking style, balance, coordination, medications, reduce tremors include anti-seizure drugs gabapentin, mild tranquilizers alprazolam, clonazepam, calcium-channel blockers, flunarizine, nimodipine, intramuscular injections of botulinum toxin, in the hand have been, reduce tremor by weakening local muscles, tremor is severe, interfering, functioning, surgery, an option to alleviate the tremor, such surgery, involves implanting a device, deep brain stimulator, specific area, the brain, the basal ganglia, caffeine, found in substances coffee, soda, stimulants, avoided, alcoholic beverages in small quantities, markedly decrease tremors but, lead to alcohol dependence, used in excess, mechanism by which alcohol decreases an essential tremor, an essential tremor is not a dangerous condition, annoying, embarrassing, severe, essential tremor, mildly interfere, fine motor skills writing, speech is occasionally involved, medications, cause side effects, essential tremor is interfering, ability to perform daily activities, side effects of medications occur, fainting, very slow heart rate, confusion, changes in alertness, lack of coordination, problems walking, prolonged nausea/vomiting, counseling, exercise, techniques helpful in reducing emotional stress, worsen the condition.
