Event related potentials and cognitive evaluation in Wilson's disease with and without neurological manifestation [Nörolojik bulgulari{dotless} olan ya da olmayan wilson hastali{dotless}g̈i{dotless}'nda olaya bag̈li{dotless} potansiyeller ve bilişsel deg̈erlendirme]

A cognitive impairment profile with the 'structured interview for the diagnosis of dementia of the alzheimer type,multi-infarct dementia,and dementias of other etiology' (sidam) including mini-mental state examination (mmse) as well as auditory evoked p300 potentials were performed in 35 adult patients with wilson's disease. patients with a neurological course of the disease by trend showed lower amplitudes,delayed latencies of p300 and lower values in the cognitive tests but all median results were still at a normal range without correlation of cognitive decline to the extent of neurological impairment. the possibility of mild cognitive impairment in wilson's disease is discussed.
