Unilateral spatial neglect constitutes a heterogeneous syndrome characterized by
two main entangled components: a contralesional bias of spatial attention
orientation; and impaired building and/or exploration of mental representations
of space. These two components are present in different subtypes of unilateral
spatial neglect (visual, auditory, somatosensory, motor, allocentric, egocentric,
personal, representational and productive manifestations). Detailed anatomical
and clinical analyses of these conditions and their underlying disorders show the
complexity of spatial cognitive deficits and the difficulty of proposing just one
explanation. This complexity is in contrast, however, to the widely acknowledged
effectiveness of rehabilitation of the various symptoms and subtypes of
unilateral spatial neglect, exemplified in the case of prism adaptation. These
common effects are reflections of the unity of the physiotherapeutic mechanisms
behind the higher brain functions related to multisensory integration and spatial
representations, whereas the paradoxical aspects of unilateral spatial neglect
emphasize the need for a greater understanding of spatial cognitive disorders.
