Some of these cases have responded well to alcohol. Symptoms vary according to the kind of dystonia involved. In most cases, dystonia tends to lead to abnormal posturing, in particular on movement.

Affected persons may notice trembling in the diaphragm while breathing, or the need to place hands in pockets, under legs while sitting or under pillows while sleeping to keep them still and to reduce pain. Trembling in the jaw may be felt and heard while lying down, and the constant movement to avoid pain may result in the grinding and wearing down of teeth, or symptoms similar to temporomandibular joint disorder.
The voice may crack frequently or become harsh, triggering frequent throat clearing. Swallowing can become difficult and accompanied by painful cramping.
When called upon to perform an intentional activity, the muscles fatigue very quickly and some portions of the muscle groups do not respond causing weakness while other portions over-respond or become rigid causing micro-tears under load.
The symptoms worsen significantly with use, especially in the case of focal dystonia, and a "mirror effect" is often observed in other body parts: Use of the right hand may cause pain and cramping in that hand as well as in the other hand and legs that were not being used.
Stress, anxiety, lack of sleep, sustained use and cold temperatures can worsen symptoms. People with dystonia may also become depressed and find great difficulty adapting their activities and livelihood to a progressing disability. Side-effects from treatment and medications can also present challenges in normal activities.
The progression may be delayed by treatment or adaptive lifestyle changes, while forced continued use may make symptoms progress more rapidly. In others, the symptoms may progress to total disability, making some of the more risky forms of treatment worth considering.

It has been found that the prevalence of dystonia is high in individuals with Huntington's diseasewhere the most common clinical presentations are internal shoulder rotation, sustained fist clenching, knee flexion, and foot inversion. Researchers suspect it is caused by a pathology of the central nervous systemlikely originating in those parts of the brain concerned with motor function—such as the basal ganglia and the GABA gamma-aminobutyric acid producing Purkinje neurons.
The precise cause of primary dystonia is unknown.
In many cases it may involve some genetic predisposition towards the disorder combined with environmental conditions. Meningitis and encephalitis caused by viral, bacterial, and fungal infections of the brain have been associated with dystonia. The main mechanism is inflammation of the blood vessels, causing restriction of blood flow to the basal ganglia.
Other mechanisms include direct nerve injury by the organism or a toxin, or autoimmune mechanisms. It has been suggested that the cerebellum plays an important role in dystonia etiology, from neuroanatomical research of complex networks showing that the cerebellum is connected to a wide range of other central nervous system structures involved in movement control to animal models indicating that signs of dystonia are due to cerebellum dysfunction and completely disappear after cerebellectomy, and finally to clinical observations in secondary dystonia patients with various types of cerebellar lesions.
It is proposed that dystonia is a large-scale dysfunction, involving not only cortico-basal ganglia-thalamo-cortical pathways, but the cortico-ponto-cerebello-thalamo-cortical loop as well.
Even in the absence of traditional "cerebellar signs" in most dystonia patients, there are more subtle indications of cerebellar dysfunction.Dystonia Society. Menu. What is Dystonia; Dystonia Research; Dystonia Research. Medical researchers don’t know what causes this movement disorder.
