Before and depressed receiving this analysis. it was my impression that schizophrenic patients usually had lower voltage, fast frequency records in cospstison to depressed patients, The latter usually boing older. had slowmaiphe records as the dominant psttetn. You: analysis activity and a that our schizophrenics had a grsstsr degree of delta significantly lesser degree of bats activity. showed Vs hsve txamined tho papnlatioo characteristics of the 20 patients at each and of the discriminate scale. First, of the 25 patients at the schisophrsnic and of the scale. 9 were labeled childhood schizophrenia and 8 now differentiated schisophrenia. More important. tho moan age of the first 20 pstients is 22.9 years and of the last 20, 43.5 years. vs hsvs roviewsd the rscords in this group of auhjacta. Two things are most striking. In comparison to the records as now sue, the Hillside records had a grant deal of alpha activity, wore exceptionslly wall modulated, with high amplitudes. Neither in the schizophrenic group not in the deptas~ sad group on us have the commonly dastribed low voltsgo. fast itaquency record. Secondly. the younger patients scan of whom aro labeled childhood schizophrenia and some of whom vets labeled undiftorsntisted sohisophronia, have no fast activity and tha only theta dominsnt and delta dominant rscotds are in these subjects. ‘ Thus. tha fraouonoy analyser data is supported by our review using visoel analysis. Tho roason for the diffiarenoe in the two groups may not lie in the diagnosis of sohisophrania es such. but in thu unique qualities of the Hillside population. To confirm this suggestion, I rsviewod ths psychopatho~ logical chstaotaristioa of these 60 patients as described in the physicians' referral rating seals. For theso patients. there were no diffsrences betwsen the childhood schisophrsnie, the dspresoad, and the schizophrenic grouse in sueh important symptoms as agitation, delusions, depression, hypoactivity. or coofueion. The only distinguishing characteristicfiwas in the incidence �Dr. Been Clyde 4-17-64 Page Two of hellucinetione uhieh appeared in h of the 9 childhood echieophtenice. a of the 21 schizophrenics. and in none of the depressive patients.
