State the aim of Neuropsychological assessment

Neuropsychological assessments aim at specifying in as much detail as possible the functional deficits that exists in a manner that allows for mapping of these deficits onto known systems in the brain. There are several methods of achieving these goals, and not all neuropsychologists agree as to the most productive route. In general, some prefer to examine patients in what may be described as a liner manner, with a series of interlocking component abilities, while others prefer using more complex tasks in the form of standard, extensive batteries and interpretation through examination of performance configurations.
