Cognitive functioning after transplantation, which could influence medication compliance and independence, has not been well studied. This study investigated cognitive impairment after lung transplantation. Patients undergoing bilateral transplant between March 2013 and October 2015 underwent comprehensive neuropsychological assessment at 60.1 44.1 months post-transplantation: verbal memory (AuditoryVerbal Learning Test, digit span forward), visual memory (Corsi Block-Tapping Test forward,

Benton Visual Retention Test), concentration/ speed of processing/attention (D2 Test of Attention, Trail Making Test (TMT) A, Grooved Pegboard), and executive functioning (TMT B, Stroop Color-Word Test, semantic and phonematic verbal fluency, digit span backward, Corsi Block-Tapping Test backward). Mean scores were compared with a normative dataset using a one-sample t-test. A cognitive domain was judged impaired if the score on two or more domain-specific tests was greater than one standard deviation below the normative dataset age range mean. Of 124 lung transplant recipients (51% male, 54.3 9.0 years), 70% showed cognitive impairment in one or more domains.

Executive function was most often impaired (78% of recipients not within the age range) followed by verbal memory impairment (72% not within the age range). Cognitive function reductions were largely independent of age, gender, education, immunosuppressive medications, and time since transplantation. The findings sh
