Pattern of neuropsychological deficits in patients with treated Wilson's disease.
The study aimed to describe the neuropsychological profiles in patients with treated Wilson's disease (WD). The series included 19 symptomatic and 2 asymptomatic patients with a mean age of 35.3 +/- 9.2 years. They were tested with the Automated Psychological Test system (APT), a comprehensive computerised neuropsychological test battery. APT comprised eleven separate tests and assessed five essential types of neuropsychological functions: motor functions, basic neuropsychological functions, specific cognitive functions, memory, and executive functions. The results were compared to current norms of the test battery. The symptomatic WD patients had significantly lower performance than the norms on all finger tapping tasks, the simple reaction time, the simultaneous capacity background task, the short-term memory test, the index of word decoding speed, the grammatical reasoning test, and the perceptual maze test. They were significantly higher on the index of impulsive errors, and used a significantly more global processing mode in the test of selective attention. The female symptomatic patients displayed more pronounced neuropsychological deficits than the males in the complex tasks. WD patients displayed a specific profile of moderate neuropsychological impairment. The results are theoretically interesting and have practical implications for the management of WD patients, e.g. some patients confronted with the results have had increased compliance.
