We report a case of congenital prosopagnosia in a woman in her 30s. The individual, who holds a university degree and works in education, sought medical attention after experiencing difficulty remembering people's faces following a job change. An MRI scan of her head revealed no obvious brain damage and neuropsychological tests showed no obvious decline in general higher brain function. However, when naming facial and head patterns in the Visual Perception Test for Agnosia Famous Face Test version 2 (VPTA-FFT ver.2), her results had a discrepancy of more than +2SD compared to healthy peers. In a task to memorize unknown faces, she did not respond smoothly and remembered clothes rather than faces. She did not have autism, which is associated with congenital decline in facial recognition. Therefore, we diagnosed this case as congenital prosopagnosia. When supporting individuals with congenital prosopagnosia who may experience challenges in daily life, it is important for speech-language-hearing therapists to collaborate with medical doctors to conduct early evaluation and diagnosis, and to provide guidance on appropriate compensatory strategies.
