Tremor Hereditary Essential
Tremor Hereditary Essential Causes
Fifty percent of ET cases are found to be due to gene mutation and are transmitted dominantly. There is no identifiable and consistent structural abnormality found to exist in the nervous system of people with ET.
Tremor Hereditary Essential Definition
Also known as essential tremor or ET, Tremor hereditary essential is a neurological disorder characterized by shaking of hands and sometimes the other parts of the body such as the head, induced by intentional movements. Though the exact incident is unknown, ET is presumed to be the most common type of tremor and also the most commonly observed movement disorder. The disease was also previously known as ?benign essential tremor? but the ?benign? was removed due to the sometimes disabling nature of the disorder.
Tremor Hereditary Essential Diagnosis
Diagnosis of ET is usually established on clinical grounds. The tremors can start from birth through advanced ages, also called senile tremor. Though it's most commonly seen in the hands, arms, and slightly less commonly in the neck, eyelids, larynx, tongue, trunk, and legs, other voluntary muscles in the body may also be affected. The disease may also sometimes occur along with other neurological disorders such as dystonia and benign fasciculation syndrome. No clear evidence however has been found to tell that a person with ET predisposes one of these disorders.
Tremor Hereditary Essential Symptoms and Signs
Though ET generally cause a rhythmic tremor that is only present when the affected muscle is exerting effort, some patients still complain about an especially coarse tremor upon waking up that becomes noticeable less coarse within the first few minutes of wakefulness. ET is also usually painless although there are times that tremors of the head and neck causes pain. Writing can also become painful for a person with hand tremors. Some people with ET also develop a raspy voice while their ET symptoms worsen over time.
Tremor Hereditary Essential Treatment
Tranquilizers, beta-blockers, and antiepileptic drugs are among the drugs used in treating ET. In severe cases, surgical treatments such as botulism toxin injection into the affected muscles, thalamotomy, pallidotomy, and deep brain stimulation (insertion of a brain pacemaker) are among the popular options.
