A movement disorder that produces uncontrollable trembling, usually in the hands.
a tremor that is associated with purposeful movement or motor activity
A common, slowly and variably progressive neurologic movement disorder characterized by involuntary, rhythmic, "back and forth" movements (i.e., tremor) of a body part or parts. In ET patients, tremor is primarily a "postural" or "kinetic" tremor or may be a combination of both types: i.e., tremor occurs while voluntarily maintaining a fixed position against gravity (postural tremor) and/or when conducting self-directed, targeted actions (kinetic intention tremor). In many individuals with ET, both hands are affected, although the condition may sometimes initially be noted in the dominant hand. ET also frequently affects the head, with tremor occurring in a "no-no" horizontal pattern in about three quarters of patients and the remainder affected by vertical "yes-yes" tremors. Less commonly, patients have tremor involving the voice, tongue, or roof of the mouth (palate), leading to impaired articulation of speech (dysarthria). Rarely, tremor may affect the trunk or lower limbs, particularly with advanced stages of disease. ET may appear to occur randomly for unknown reasons (sporadically) or be transmitted as an autosomal dominant trait.
tremor of unknown cause (usually of the hands and head) that develops in older people; often mistaken for Parkinsonism but is not life-threatening and can usually be kept under control
The most common disorder in a group of neurological conditions called “movement disorders.” Patients with essential tremor have no symptoms other than tremor, which may occur in their hands, head, legs, trunk or voice.
Essential tremor belongs to a group of conditions called "movement disorders" and is the most common disorder in this group. Essential tremor patients have no symptoms other than tremor-a rhythmic, shaking movement produced by muscle contractions which may occur in the hands, head, legs, trunk, or voice. Essential tremor is a progressive disease and tends to run in families. Many physicians identify abnormal activity of brain cells as the suspected mechanism of tremor.
a condition more common than Parkinson disease, which often includes shaking of the hands or head, and an unsteady quality of the voice
The most common form of tremor, which typically begins in adolescence and young adulthood and becomes more pronounced in middle to advanced years, i.e., after age 50. It comprises a single symptom such as uncontrollable shaking of the head, hands, arms, or other part of the body, which stops when at rest. The condition is often hereditary.
A fast tremor (about eight cycles per second) that is most pronounced when performing an action such as writing or bringing a hand to a target
Essential tremor is a neurological disorder characterized by shaking of hands (and sometimes other parts of the body including the head), evoked by intentional movements. The incidence is unknown, but is estimated to be as common as one person in 20, and it is the most common type of tremor and also the most commonly observed movement disorder.
