What is Dystonia?

Dystonia is a neurological movement disorder characterized by involuntary muscle contractions that cause repetitive movements, abnormal postures, or both. These contractions can affect one part of the body (focal dystonia), multiple areas (segmental dystonia), or the entire body (generalized dystonia). The severity and impact of dystonia vary widely among individuals.

Key Features of Dystonia:

1. Involuntary Movements: The hallmark of dystonia is sustained or intermittent muscle contractions that are uncontrollable.
2. Abnormal Postures: The movements often result in twisted or awkward postures.
3. Variable Symptoms: Symptoms can be mild (e.g., slight tremor) or severe (e.g., debilitating muscle contractions).
4. Task-Specificity: Some forms of dystonia, like writer’s cramp, occur only during specific activities.
