title: Neurologic complications of bariatric surgery.
abstract: OBJECTIVE
  The increasing utilization of bariatric surgery has been accompanied by an increased incidence and awareness of related neurologic complications. The purpose of this review is to provide up-to-date information on the neurologic complications related to bariatric surgery.
  
  
  RESULTS
  Neurologic complications related to bariatric surgery are predominantly due to nutrient deficiencies. Common early complications include Wernicke encephalopathy due to thiamine deficiency, and late complications include myelopathy or myeloneuropathy due to vitamin B12 or copper deficiency.
  
  
  CONCLUSIONS
  Early recognition and prompt institution of treatment is essential to prevent long-term disability. Often, life-long supplementation may be required.
