Assessment of change in behavioral functioning in children as a function of neurotoxicity is not a trivial undertaking. Psychological tests, widely (though erroneously) considered to be the "gold standard" for measurement of behavior in humans, are not adequate for the task; they tap the structure of cognition, not the behavioral repertoire, and cannot (alone) address developmental change. Comp...

: http://si p://pubs.as The goal of this article is to outline the utility of both language and non-language testing in making a diagnosis of logopenic, nonfluent/agrammatic, and semantic variant primary progressive aphasias PPA as well as delineate important behavioral and speech features that can be detected via clinical observation. We review speech/language presentations, non-language cogni...

The use of clinical neuropsychological tests in the evaluation of National Football League (NFL) players has been ongoing for more than two decades. Prior research has demonstrated that the NFL population may perform differently than the general population on standard paper and pencil neuropsychological tests. Given the increased interest in the longitudinal and long-term assessment of neurocog...

OBJECTIVE Poor effort on baseline neuropsychological tests is expected to influence interpretation of post-concussion assessment scores. Our study examined effort in an athletic population to determine if poor effort effects neuropsychological test performance. METHODS High school athletes (N=199) were administered a brief neuropsychological test battery, which included the Dot Counting Test ...

Professional and amateur participants in many sports are at risk of brain injury caused by impact with other players or objects. In many cases, mild cognitive deficits may persist after the common neurological signs of brain injury have passed. In recent years, the athlete's cognitive status after concussion has been measured with conventional "paper and pencil" neuropsychological tests. Howeve...

Objective: Conversion disorder is characterized by functional impairment in motor, sensory, or neurovegetative systems that cannot be explained by a general medical condition. Diagnostic systems emphasize the absence of an organic basis for the dysfunction observed in conversion disorder. Nevertheless, there is a growing body of data on the specific functional brain correlates of conversion sym...

OBJECTIVES To present current applications of computer-based neuropsychological assessment, including the assessment of sports-related concussion, symptom validity testing, and the remote administration of tests through the Internet. PROBLEM AREAS If computer-based assessment benefits are to become popularized, a few issues will need to be addressed: the development of psychometric data based...

We developed a neuropsychological battery for assessment of cognitive processes that was standardized in 150 neurologically intact subjects from different socioeducational levels in Mexico City (Ostrosky et al., 1985, 1986). The present study was designed to explore the capacity of this neuropsychological battery to discriminate a brain-injured population from a normal one. Thirty-four patients...

OBJECTIVE Event-related brain potentials (ERPs) were used to assess language function after stroke and demonstrate that it is possible to adapt neuropsychological tests to evaluate neurocognitive function using ERPs. Prior ERP assessment work has focused on language in both healthy individuals and case studies of aphasic neurotrauma patients. The objective of the current study was to evaluate l...

AIMS To study neuropsychological functioning of newly diagnosed children with acute lymphoblastic leukaemia (ALL) within two weeks after diagnosis in order to determine the feasibility of a sibling controlled prospective study design. METHODS Fifty consecutive patients (median age at testing 6.6 years, range 4-12) were included in a prospective, longitudinal, nationwide study. Treatment would...
