title: Face recognition in patients with migraine.
abstract: OBJECTIVE
  Prosopagnosia is a rare dysfunction seen during the aura phase of migraine. We aimed to evaluate the face recognition, which has not previously been investigated in migraineurs during the interictal period, and its relationships with clinical features.
  
  
  METHODS
  Seventy-four migraineurs, with or without aura, diagnosed according to the International Headache Society criteria and 37 healthy control subjects were included. Benton face recognition test (BFRT) and judgment of line orientation test (LOT) for complex visual perception were applied to all participants.
  
  
  RESULTS
  Migraineurs showed significantly lower performance in both of the BFRT and LOT scores (P = 0.027; P = 0.014, respectively), indicating impaired visuospatial perception. In the subgroup analysis, these impairments were more pronounced in the group with migraine without aura.
  
  
  CONCLUSIONS
  Migraineurs had poorer performance in both face recognition and visuospatial perception. These findings could be based on functional differences in the migraineurs' brain or genetic changes.
