Neglect, Sensori-motricity and Cognition

Keynote Lecture by Gilles Rode, France

Spatial neglect is the most frequent and handicapping deficit following a damage of the right cerebral hemisphere. It constitutes a heterogenous syndrome characterized by two main entangled components: a contralesional bias of spatial attention orientation, and an impaired building and/or exploration of mental representations of space, which are present in different subtypes (visual, auditory, somatosensory, motor, allocentric, egocentric, personal, representational or productive manifestations). These subtypes are targets for cognitive rehabilitation. Rehabilitation relies on 'top-down' (visual scanning training, cueing, mental practice or imagery) and 'bottom-up' methods (sensory stimulation, prism adaptation, half-field eye patching, spatio-motor cueing, arm-activation intervention or mirror therapy), according to interaction between sensory-motor and cognitive processes. Lastly the ICF opens perspectives for the rehabilitation of spatial neglect by proposing a holistic rehabilitation from science to practice, from the patient to his environment of life.
