A Neuropsychological Normative Database for Lung Transplant Candidates

Psychologists are increasingly asked to make decisions regarding patient candidacy for transplantation. Despite the growing incidence of lung transplantation, normative research regarding cognitive functioning and end-stage obstructive lung disease is lacking. Hence, data are presented on 100 consecutively referred candidates for lung transplantation. The group data suggest essentially normal functioning on most cognitive tests for the majority of transplant candidates. Exceptions were seen on measures of attentional set shifting and short-term visual memory, which were impaired in nearly one fourth of this population. Additionally, one half of the patients displayed deficient performance on the Buschke Selective Reminding Test, with subjects at greater risk for severe rather than mild deficits. Unlike prior research, our group data suggest that there is potential risk of short-term noncontextual verbal memory difficulties because of end-stage pulmonary disease. Personality testing data, e.g., elevations on MMPI-2 scales measuring depression and anxiety, are also discussed.
