Movement disorders like dystonia and tremors can occur after brain or spine surgery. These conditions, often delayed, can cause significant disability and require specific treatments.

Area of Science:

  • Neurology
  • Neurosurgery
  • Movement Disorders

Background:

  • Limited knowledge exists on movement disorders following neurosurgery, excluding functional stereotactic procedures.
  • This study analyzes 14 patients with movement disorders secondary to craniocerebral or spinal surgery.

Observation:

  • Movement disorders manifested after a delay in most patients, with dystonia and tremors being most common.
  • Lesions in the contralateral striatum correlated with dystonic syndromes, and dentatothalamic outflow lesions with tremors.
  • Postoperative movement disorders were persistent in 11 patients, causing marked disability in four.

Findings:

  • Dystonic syndromes and tremors are the most frequent movement disorders post-neurosurgery.
  • Delayed onset of movement disorders is common, with tremors appearing around 5 weeks and dystonia around 5.5 months.

  • Pathoanatomical correlations align with those seen in other secondary movement disorder cases.

    • Implications:

    • Postoperative movement disorders can lead to significant functional impairment.
    • Medical treatments, including botulinum toxin injections and thalamotomy, offer limited but potential benefits.
    • Understanding these neurological sequelae is crucial for managing patients undergoing neurosurgical interventions.
