Guanfacine for the Treatment of Spatial Neglect and Impaired Vigilance

Summary

To find out if spatial neglect following stroke and brain injury can be reduced using guanfacine, a drug that was shown to improve neglect in two stroke patients in a previous pilot study (Malhotra et al, 2006). In this trial, the effects of guanfacine will be examined in a larger number of patients, and there will also be a systematic assessment of whether the drug is only effective in patients with particular patterns of brain damage.
