The Puzzles Test and the Red Shapes Test as new diagnostic tools for neglect syndrome

Abstract

Introduction Neuropsychological methods for diagnosing neglect syndrome (NS) are focused on identifying the inability of patients to respond to stimuli localized in contralesional space. There are a large number of methods capable of diagnosing spatial neglect, but at the same time having various limitations and restrictions in their use. Objectives To devise and to test universal diagnostic techniques for visuospatial neglect detection. Methods 1) A.R. Luria test battery; Trail Making Test (Part A); the Bells Test; 2) Authors’ methods: the Puzzles Test, the Red Shapes Test. A total of 47 patients after stroke with right hemisphere damage participated in the study and were divided into a target (18 patients with NS) and a control (29 patients without NS) groups. The Puzzles Test consists of three tasks: turning over cards, completing a sentence using cards with letters, completing a picture. The Red Shapes Test consisted in the search for a variable number of geometric shapes. Objective indicators of the study: total task completion time, the number of left omissions. Results The sensitivity of the tests to NS was examined using the Mann-Whitney U-test. Differences in the number of omissions and task completion time between patients with and without spatial neglect were statistically significant regarding all tasks: turning over cards (p=0.01), completing a sentence (p<0.001), completing a picture (p<0.001), finding geometric shapes (p<0.01). Conclusions The Puzzles Test and Red Shapes Test along with the foreign tests (the Bells Test, Trail Making Test) are sufficiently effective methods for spatial neglect detection. Disclosure No significant relationships.
