Serial assessments are now common in neuropsychological practice, and have a recognized value in numerous clinical and forensic settings. These assessments can aid in differential diagnosis, tracking neuropsychological strengths and weaknesses over time, and managing various neurologic and psychiatric conditions. This document provides a discussion of the benefits and challenges of serial neuropsychological testing in the context of clinical and forensic assessments. Recommendations regarding the use of repeated testing in neuropsychological practice are provided.

A new 15-item MMPI-2 subscale, the Henry-Heilbronner Index (HHI), representing a "pseudosomatic factor," was empirically derived from both the 43-item Lees-Haley Fake Bad Scale (FBS) and the 17-item Shaw and Matthews' Pseudoneurologic Scale (PNS). The HHI was superior to both the FBS and PNS in identification of symptom exaggeration in personal injury litigants and disability claimants compared to non-litigating head-injured controls. Logistic regression analyses revealed that a cutscore of > or = 8 on the HHI was associated with good specificity (89%) and sensitivity (80%). These results suggest that the HHI may be useful in identifying personal injury litigants and disability claimants who exaggerate, overreport, or malinger physical symptoms on the MMPI-2 related to their current health and/or litigation status.

The present retrospective study was undertaken to determine whether Trail Making Test A and B, Digit Span Forward and Backward, and TPT Memory and Location scores are differentially sensitive to right or left hemisphere brain damage. Groups of patients with right, left, and generalized cerebral lesions and matched normal controls were compared. Results showed a relative failure for any individual measure, difference, or ratio score to reliably distinguish between right and left hemisphere lesions. Patients with diffuse lesions performed significantly worse than non-neurologic medical controls and right and left lesion groups on Trails A and TPT Memory and Location. Results are discussed in terms of specific methodological variables including chronicity of lesion, the nature of the task demands, and priming effects.
