Tremor

Tremors are unintentional trembling or shaking movements in one or more parts of your body. Most tremors occur in the hands. You can also have arm, head, face, vocal cord, trunk, and leg tremors. Tremors are most common in middle-aged and older people, but anyone can have them.

The cause of tremors is a problem in the parts of the brain that control muscles in the body or in specific parts of the body, such as the hands. They commonly occur in otherwise healthy people. They may also be caused by problems such as

  • Parkinson's disease
  • Dystonia
  • Multiple sclerosis
  • Stroke
  • Traumatic brain injury
  • Alcohol abuse and withdrawal
  • Certain medicines

Some forms are inherited and run in families. Others have no known cause.

There is no cure for most tremors. Treatment to relieve them depends on their cause. In many cases, medicines and sometimes surgical procedures can reduce or stop tremors and improve muscle control. Tremors are not life threatening. However, they can be embarrassing and make it hard to perform daily tasks.

Disorders associated with tremor

Essential tremor is the most common form of tremor of moderate frequency ranging from 7-12 Hz and presents as a postural and kinetic tremor of the hands. It may also be present in the head/neck, and voice.

    Essential tremor or related tremors

    Hereditary essential tremor is an inherited movement disorder characterized by intentional involuntary tremor, mainly of the hands.

    Movement disorders

    Tremor is an involuntary oscillation of a body part and is commonly classified according to the behavioral circumstances in which it occurs (1) Tremor may occur during attempted relaxation (rest tremor), during a voluntarily held posture (postural tremor), or during a voluntary movement (kinetic tremor).

    Other rhythmic disorders

    Hereditary chin trembling is a rare autosomal dominant condition that has been linked to chromosome 9q13-21. characterized by paroxysmal, often rhythmic up-and-down movements of the chin and the lower lip. The episodes last from seconds to hours and may be triggered by emotion, anxiety, or may occur without apparent precipitants. The condition typically becomes manifest in infancy or in early life, and the episodes tend to reduce in frequency with advancing age.

    Rest tremor

    The rest tremor in Parkinson Disease and Parkinsonism is asymmetric at onset most commonly affecting the hand and described as a pill rolling tremor. It is usually 4-5 hz in frequency and may spread to other parts of the body.

    Task-specific tremor

    Primary writing tremor (PWT) is a commonly encountered task specific tremor occurring at a frequency of 5-7 Hz. It is currently debatable whether PWT represents a form of essential tremor, dystonic tremor or a separate entity.

    Tremor due to metabolic disorders

    Hypoglycemia can produce a tremor which shows improvement with treatment of the underlying condition.
