Tests and diagnosis

By Mayo Clinic Staff

To diagnose your condition, your doctor will review your signs and symptoms and conduct a physical examination.

You'll be asked to provide your complete medical history, including any family history of dystonia, previous head injury or stroke, or exposure to toxins or drugs.

You may have other tests to determine if underlying conditions are causing your symptoms. Tests may include:

  • Blood or urine tests. These tests may reveal the presence of toxins.
  • Computerized tomography (CT scan). A CT scan uses a series of X-rays to create a detailed, 3-D view of your brain.
  • Magnetic resonance imaging (MRI). An MRI uses powerful radio waves and magnets to create a detailed view of your brain. This test may be conducted to identify tumors, lesions or evidence of a stroke.
  • Electromyography (EMG). This test measures the electrical activity within muscles.
