Get StartedTests and diagnosis
By Mayo Clinic staffA diagnostic work-up will include a thorough assessment of your symptoms, usually by a neurologist. Your doctor will also take a complete medical history to identify dystonia in the family, previous head injury or stroke, exposure to toxins or drugs, or evidence of other potential secondary causes. Blood or urine tests may reveal the presence of toxins, and MRI may be used to identify tumors, lesions or evidence of stroke.
