Analysis of the Syndrome of Unilateral Neglect

Using a variety of clinical measures of unilateral neglect 40 right hemisphere lesioned stroke subjects were compared in terms of neuropsychological deficit. The results of the study encourage the view that unilateral neglect is a complex syndrome and subjects who indicate the disorder may vary in systematic dimensions. There are at least two factors contributing to the neglect syndrome — a scanning factor of external stimuli and a disrupted internal representation of space factor. Both the obtained factors were correlated with functional independence at 6 months post-stroke in a further group of 27 right hemisphere lesioned stroke patients. It is probable that most commonly these factors co-exist and form the classical neglect syndrome but theoretically they may occur separately and this leads to implications for management.
