Familial forms often appear early in life. Essential tremor is an inherited condition in 50-70% of cases (referred to as familial tremor). The exact cause of essential tremor is unknown. Studies show essential tremor is accompanied by a mild degeneration of the cerebellum, which is the part of your brain that controls movement coordination. It can be mild and stay mild, or slowly get worse over time. It also may affect a person’s head, voice, or lower limbs. Although the tremor can start at any age, it most often first appears during adolescence or in middle age (between ages 40 and 50). Some of the most common forms include: Essential tremorĮssential tremor (previously also called benign essential tremor or familial tremor) is one of the most common movement disorders. Its key feature is a tremor in both hands and arms during action without other neurological signs. Tremor syndromes are defined based on the pattern of the tremor. Isometric tremor occurs during a voluntary muscle contraction that is not accompanied by any movement, such as when holding a heavy book in the same position.Task-specific tremor only appears when performing goal-oriented tasks such as handwriting or speaking.Intention tremor starts when the person makes an intended movement toward a target, such as lifting a finger to touch their nose.Kinetic tremor is associated with any voluntary movement, such as moving the wrists up and down or closing and opening your eyes.Postural tremor occurs when holding a position against gravity, such as holding the arms outstretched.There are several sub-classifications of action tremor, many of which overlap. Action tremor occurs when a muscle is moved voluntarily. People with Parkinson’s disease often experience rest tremor. Rest tremor occurs when people are at rest. These categories are rest and action tremor. Tremor is categorized based on when and how the tremor is activated. Some tremor can be triggered by stress or strong emotion, being physically tired, or being in certain postures or making specific movements. Problems holding and controlling utensils, tools, or other items.Rhythmic shaking of the hands, arms, head, legs, or torso.Tremor can make daily life tasks such as writing, typing, eating, shaving, and dressing more difficult. Tremor is not life threatening, but it may cause challenges and even lead to disabilities. Tremor can occur on its own or as a result of another disorder. The tremor may be constant, or only happen sometimes. Tremor is a neurological condition that includes shaking or trembling movements in one or more parts of the body, most commonly affecting a person’s hands. It can also occur in the arms, legs, head, vocal cords, and torso.
