[Set of neuropsychological tests for the assessment of language disorders after damage to the right cerebral hemisphere: preliminary results].

A set of five experimental tests was prepared for the assessment of language disturbances in right hemisphere-damaged (RHD) patients. The Right Hemisphere Language Battery by Bryan (1995) was a basis for these tests. The set comprises the Metaphor Picture Test, the Written Metaphor Test, the Inferential Meaning Test, the Humour Test and the Lexical Semantic Test. Thirty-six RHD, 15 left hemisphere damaged (LHD) without aphasia and 30 control (C) subjects took part in the investigation. All test significantly differed between the RHD and C groups. No significant differences were noted between LHD and control groups, except for the Inferential Meaning Test. The quantitative performance of tests was different in all the groups. Results of the study indicated patients with right frontal damages to make more errors than those with right posterior lesions.
