Lottery game helps patients

Patients recovering from stroke sometimes behave as if completely unaware of one half of the world: colliding with obstacles on their left, eating food only from the right side of their plate, or failing to dress their left side. This puzzling phenomenon is termed "spatial neglect" and it affects roughly 45% of patients suffering from a stroke in the right side of the brain. The condition can indicate a long road to recovery, but researchers have now developed a quick and simple lottery game, which can be used to assess the extent of these symptoms and potentially aid the design of rehabilitation programmes. The findings are reported in the May 2010 issue of Elsevier's Cortex (http://www.elsevier.com/locate/cortex).
