Forms of Dystonia

There are several forms of dystonia, and dystonia may be a symptom of many diseases and conditions. If you want to investigate a specific form or sub-form of dystonia, just click any one of the links below. 

Focal Dystonias

Focal dystonias are adult-onset forms that affects a specific area of the body. Most focal dystonias are primary (meaning that it is the only neurological symptom and presumed to have a genetic component), though secondary cases are documented. Focal dystonia may affect muscles of the eyes, mouth, vocal cords, neck, hands, and feet.

Types of Focal Dystonia:

Blepharospasm: dystonia that affects the muscles of the eyelids and brow

Cervical Dystonia: dystonia that affects the neck and sometimes the shoulders

Laryngeal Dystonia(Spasmodic Dysphonia): dystonia that affects the vocal cords

Oromandibular Dystonia: symptoms include forceful contractions of the face, jaw, and/or tongue

Writer's Cramp (Hand Dystonia): dystonia of the fingers, hand, and/or forearm


Secondary Dystonias

Primary dystonias are genetic (or believed to be genetic) in origin, whereas secondary dystonias result from apparent outside factors and can be attributed to a specific cause such as exposure to certain medications, trauma, toxins, infections, or stroke. You can learn more about secondary dystonia here

Causes of Secondary Dystonia:

Drug-Induced: specific drugs are capable of causing dystonia

Neurological and Metabolic Diseases: dystonia can occur as a symptom of multiple disorders

Toxins: several rare toxins are known to cause movement disorders

Trauma: dystonia may follow trauma to the head and/or to a specific body area


Musician's Dystonia

Professional musicians are susceptible to a variety of specific occupational injuries, including task-specific focal dystonia. If you are an afflicted musician and would like support and more information for your specific issues, you can access the Musicians With Dystonia Bulletin Board to find material related to your specific needs.
