Essential tremor
Essential Tremor (pronunciation: /ɪˈsɛnʃəl ˈtrɛmər/) is a neurological disorder characterized by involuntary and rhythmic shaking. The term "essential" refers to the fact that the tremor is not associated with any other disease or condition.
Etymology
The term "essential" in Essential Tremor originates from the Latin word "essentia," meaning "being," and the term "tremor" originates from the Latin word "tremere," meaning "to shake."
Symptoms
Essential Tremor primarily affects the hands, but it can also affect the arms, head, voice, jaw, and legs. The tremor may be barely noticeable in its early stages but tends to progressively worsen over time.
Causes
The exact cause of Essential Tremor is unknown. However, it is believed to be caused by electrical changes in the brain that send abnormal signals out to the muscles. Some studies suggest that the cerebellum, the part of the brain that controls muscle movements, does not work correctly in patients with Essential Tremor.
Diagnosis
Diagnosis of Essential Tremor involves a physical examination and a review of the patient's medical history. The doctor may also order a neurological examination to rule out other conditions that could be causing the tremors.
Treatment
Treatment for Essential Tremor may include medications, physical therapy, and in some cases, surgery. Medications used to treat Essential Tremor include beta blockers, anti-seizure medications, and tranquilizers.
