[Neuropsychological tools in neurological practice].

Neuropsychology is transdiscipline. Neuropsychological examination concerns cognition and behaviour. Neuropsychological examination is a part of neurological examination as walk is. Neuropsychological examination associates conversation and tests. We can distinguish tests for screening, for managing, first line tests and specialized ones (psychometric tools). A test is an experimental standardized situation to measure a behaviour and to compare it with statistical analysis with those of other people in the same situation. The test authorizes a quantitative or typological classification. The choice, the realization, the analysis and the singular relation are at the heart of the neuropsychology.
