title: [Cognitive dysfunction in patients with subclinical hypothyroidism].
abstract: OBJECTIVE
  Evaluate neuropsychological changes in patients with subclinical hypothyroidism (SH).
  
  
  METHODS
  Cross-sectional study comparing the results of the neuropsychological evaluation of 89 SH patients and 178 individuals without thyroid disease. The participants underwent the following neuropsychological assessment: Conner's Continuous Performance Test (CPT-II), Iowa Gambling Task, Stroop Test, Wisconsin Card Sorting Test (WCST), Verbal Fluency Test (semantic and phonologic categories) and Rey Auditory Verbal Learning Test.
  
  
  RESULTS
  Among the neuropsychological tests, patients showed worse performance only in cognitive flexibility (WCST) and the ability to maintain sustained attention (omission errors on the CPT-II).
  
  
  CONCLUSIONS
  These losses can cause detriments in the daily lives of patients, constituting potential treatment indications.
