TEST YOURSELF
(1) In this Case Report what is the possible cause of the deterioration of dyslexia?
(2) Would it have been more appropriate to perform a preoperative Wada test or fMRI for language lateralization? Would this have prevented the unusual complication?
Answers
(1) Based on a thorough analysis of this case, we suggest that this was caused by a combination of: (1) postoperative disruption of a right-sided cortical compensating neuronal system for language; and (2) postoperative disruption of the hippocampal visual memory mechanism. We hypothesize that due to disruption of these mechanisms, insufficient visual support was generated for sequential information structuring.
(2) fMRI or Wada testing should be included as part of the preoperative counselling for patients with a known reading disorder, however, we believe that this would not have prevented the unusual complication described in this case.
