EEG antecedents of thievery

In Gothenburg studies using clinical and electroencephalographic techniques have been undertaken continuously since 1958 on a large number of individuals of all ages. All individuals studied were without impairment to the central nervous system, according to a number of well-defined defined clinical criteria, and were termed normal. The term "normal" is used primarily because it is short. As part of the continued investigation, information has been gathered from social bureaus in Gothenburg and from federal registers. It was observed that youths and children who were found guilty of theft showed EEG abnormalities of some kind (in the EEGs taken several years earlier) statistically significantly more often than other youths and children belonging to our normal material. Among the characteristics discovered by EEG can be noted paroxysmal activity during sleep, slow alpha activity and spectral-analytical measurements corresponding to lower EEG ages than the individuals' actual ages.
