Neck-tongue syndrome (NTS) is a headache disorder often initiated by rapid axial rotation of the neck resulting in unilateral neck and/or occipital pain and transient ipsilateral tongue sensory disturbance. In this review, we examine reported cases of NTS since its initial description in 1980 to highlight the significance of this condition in the differential diagnosis of headache in patients presenting with neck pain and altered tongue sensation. The anatomical basis of NTS centers on the C1-C2 facet joint, C2 ventral ramus, and inferior oblique muscle in the atlanto-axial space. NTS may be categorized as complicated (secondary to another disease process) or uncomplicated (hereditary, related to trauma, or idiopathic). Diagnosis is based on clinical suspicion after a thorough history and physical without a pathognomonic radiologic finding. It is typically treated conservatively with medications, local injections, immobilization with cervical collars, or physical therapy; rarely is surgical intervention pursued.
