    Spasmodic dysphonia (SD) may follow head injury. Neurodiagnostic tests revealed positive neurologic findings in patients with SD after head trauma, suggesting underlying brain abnormalities.

    Area of Science:

    • Neurology
    • Otolaryngology
    • Voice Science

    Background:

    • Spasmodic dysphonia (SD) is a rare voice disorder with an unknown etiology.
    • A subset of SD patients report symptom onset after head injury.
    • This study investigates neurodiagnostic findings in SD patients with a history of head trauma.

    Observation:

    • Three patients with spasmodic dysphonia and a history of head injury underwent comprehensive neurodiagnostic evaluations.
    • Evaluations included computed tomography (CT), magnetic resonance imaging (MRI), auditory brain-stem response (ABR), brain electrical activity mapping (BEAM), and single photon emission computed tomography (SPECT).
    • Two or more tests indicated positive neurological findings for each patient.

    Findings:

    • Abnormalities were detected in at least one patient across most neurodiagnostic tests, with the exception of CT.

  • MRI, ABR, BEAM, and SPECT collectively revealed evidence of central nervous system dysfunction.
  • These findings suggest a potential link between head trauma and the development of spasmodic dysphonia.

    • Implications:

    • Clinical history of head trauma is a significant factor in evaluating patients with spasmodic dysphonia.
    • A single negative neurodiagnostic test does not rule out underlying neurological lesions in SD patients.
    • Further research is warranted to elucidate the neurobiological mechanisms connecting head injury and spasmodic dysphonia.
