2. It May Be Mistaken For Other Disorders
The Dystonia Medical Research Foundation notes the disorder can occur in tandem with other movement disorders, or resemble other conditions, potentially making it difficult to diagnose. For example, many sufferers also experience a head tremor, but tremors do not necessarily suggest dystonic postures will follow.
The disorder can also be mistaken for Parkinson’s disease, which itself is a neurological movement disorder that causes shaking and rigid muscles. However, it’s also possible for both conditions to co-exist within the same patient, adds the source.
