Dystonia Disorder is a neurological movement disorder characterized by involuntary muscle contractions that cause repetitive or twisting movements. It can affect various parts of the body, such as the neck (cervical dystonia), face (cranial dystonia), or limbs (limb dystonia). The prevalence of Dystonia Disorder varies depending on the specific type and population studied.
Primary dystonia, which is not associated with any other underlying condition, has an estimated prevalence of approximately 30 to 732 cases per million individuals. The most common form of primary dystonia is cervical dystonia, affecting about 60 to 90 cases per million people.
Secondary dystonia, which is caused by an underlying condition or injury, has a higher prevalence. For example, dystonia associated with Parkinson's disease affects around 30% of Parkinson's patients.
It is important to note that the prevalence rates may vary due to differences in diagnostic criteria, study populations, and geographical locations. Additionally, dystonia is often underdiagnosed or misdiagnosed, making it challenging to determine the exact prevalence.
If you suspect you or someone you know may have dystonia, it is crucial to consult a healthcare professional for proper evaluation and diagnosis.
