We report Developmental Landmark Agnosia (DLA) in a 6-year-old boy (L.G.) who was referred to
us for congenital prosopagnosia (see Pizzamiglio et al., 2017, in which both testing and
rehabilitation of Congenital Prosopagnosia are reported). We investigated his performance using a
neuropsychological battery and eye movement recordings. The assessment showed the presence
of deficits in recognizing familiar places (along with Congenital Prosopagnosia), but not common
objects. Eye movement recordings confirmed his problems in recognizing familiar landmarks and
misrecognition of unfamiliar places. L.G. is the first evidence of a DLA, suggesting identification of
taxonomy of navigational disorders in Developmental Topographical Disorientation is possible, as
in the Acquired Topographical Disorientation.
