Brain lesions, location and cervical dystonia

Takeaway

  • Cervical dystonia is caused by lesions located in regions that map to a common brain network defined by connectivity to the cerebellum and the somatosensory cortex; these regions are also abnormal in patients with idiopathic cervical dystonia, and align with effective deep brain stimulation (DBS) sites.

Why this matters

    Lesion network mapping can guide the search for brain abnormalities and treatment targets in non-lesion patients with similar neurological symptoms.
