The electroencephalograms (EEGs) of 127 subjects with intellectual disability were analysed with regarding to their correlation to intellectual functions in order to further understand the relationships between EEG and intelligence. The EEG frequency spectrum was subdivided into 15, 2-Hz-wide bands and was recorded from electrodes F1, Fpz, Fp2, F7, F3, Fz,(More)
BACKGROUND Perception disorders are frequently observed in persons with intellectual disability (ID) and their influence on cognition has been discussed. The objective of this study is to clarify the mechanisms behind these alterations by analysing the visual event related potentials early component, the N1 wave, which is related to perception alterations(More)

Differential diagnosis was made between neuroleptic malignant syndrome or catatonic syndrome complicated by infection. The signs and symptoms observed throughout the patient's course are detailed. 3. A critical review is made of bibliography on the(More)
INTRODUCTION It has been argued if the frontal, N1a, is the early part of the occipito-temporal, N1b, or there are two different waves. It is also not clear whether the N1 of distractor is equivalent to the target N1, neither to distinguish these four waves has some functional value. PATIENTS AND METHODS We performed a principal component analysis of(More)
The present study compared two group of subjects with intellectual disability. The 44 subjects in group 1 had equivalent verbal and performance IQs (67 and 64, respectively), while the 12 subjects in group 2 had an intellectual performance IQ which was > or = 10 points above their verbal performance IQ (80 and 65, respectively). The second group showed an(More)
