What is the difference between dystonia and tardive dyskinesia?
Tardive dyskinesia is characterized by truncal, appendicular, or orobuccolingual choreiform movements; whereas tardive dystonia manifests as stereotyped twisting and turning muscle spasms. Tardive dyskinesia also tends to have a later age of onset than tardive dystonia.
Is antipsychotic dystonia permanent?

What is the difference between dystonia and chorea?
Dystonia is a movement disorder in which involuntary sustained or intermittent muscle contractions cause twisting and repetitive movements, abnormal postures, or both. Chorea is an ongoing random-appearing sequence of one or more discrete involuntary movements or movement fragments.
How fast does dystonia progress?
Cervical dystonia can occur at any age, although most individuals first experience symptoms in midlife. It often begins slowly and usually reaches a plateau over a few months or years. About 10 percent of those with torticollis may experience a spontaneous remission, but unfortunately the remission may not be lasting.

Infections. Meningitis and encephalitis caused by viral, bacterial, and fungal infections of the brain have been associated with dystonia, choreoathetosis, and ballismus. Movement abnormalities usually develop during the acute phase of the illness and are transient.
What’s the difference between tardive dystonia and dyskinesia?
Tardive dyskinesia is a movement disorder that develops after exposure to dopamine receptor blocking agents. Less well-appreciated are other, more recently described tardive syndromes that are phenomenologically distinct from tardive dyskinesia and respond to different treatments. Patients may simul … Tardive Dystonia
What are the side effects of dystonia in children?
Central side effects include memory loss, confusion, restlessness, insomnia, and nightmares. Children may experience chorea, or exacerbation of a pre-existing tic disorder.
