NEUROLOGY

A screening tool that was developed to detect the presence of unilateral visuo-spatial neglect* in the near extrapersonal space in patients with stroke.

In the test field of a seeming jumble of words, letters and stars are 56 small stars. The examiner demonstrates the test task, which is to cancel all of the remaining 54 stars. Missing 3 or more stars confirms neglect in stroke patients. The test has excellent construct and criterion validity, but little published data on its reliability. 

*Visuo-spatial neglect is an important predictor of poor outcome after stroke.”
