DENVER — End-stage liver disease was associated with significant deficits in memory, abstract thought, sustained attention, and executive function in a study of 104 adult patients, Tina Meyer, Ph.D., reported in a poster presented at the annual meeting of the American Psychosomatic Society.
“We want to enlighten the surgeons and primary care doctors that cognitive decline can indicate serious liver problems,” Dr. Meyer said in an interview.
She and her colleagues in the Transplant Institute at the Henry Ford Health System in Detroit enrolled liver disease patients who met medical and psychosocial criteria for a transplant. About half (51%) were male, 74% were white, and the average age was 54 years. The patients' average score on the mean model for end-stage liver disease (MELD) was 11.3.
The participants completed a cognitive assessment including the Repeatable Battery for the Assessment of Neuropsychological Status (RBANS), which estimates brain function in five different domains: immediate memory, delayed memory, visuospatial abilities, language, and attention.
Overall, scores on the RBANS were below average on the subtests of immediate memory, visuospatial abilities, and attention. After the investigators controlled for education levels, higher MELD scores were significantly associated with lower scores on the immediate memory and delayed memory subtests of RBANS, as well as with lower scores on the Mini-Mental State Exam, the Shipley Institute of Living Scale, and the Trail-Making Test, parts A and B.
