Wem‘ _.__ Hey 17, 1971 Dr. Gordon Marjorrison Department of Psychiatrv University Hospital Saskatoon, Canada Dear Gordon, I want to thank you for the pre~puhlication copy of your study "Electrocnnvulsive lherapyt EEG and Clinical Effects." I found it very interesting. First, I am enclosing a copy of the proper citation for the slow wave EEG differences, and suggest that both the text and the reference list be corrected in galley. Bro. Volevka and Veldetein have re~anelyzed this data quantitatively, and the findings stand. text, it is clear that the REC behavioral reported were not replicated. But Table II vielde another fact, that indeed depression scores increased with increasing delta (9 < .05, r - +.26 w +.29) i“§fiii锧hx1ecv and excitement decreased. In this correct? In reading the relations we I also find the correlations in Table IV confusion. The negative correlations are consistent with our experience, but the positive correlation of increased delta voltage and increased scores in emotional withdrawal and conceptual disorganization reflects some other process. Are these interpretations correct? principal difference in our experience is in Table II. a sun of the observations in schizOphrenic and depressed patients combined, it may help understand the correlations. Since the evquotions were done 1 week after a varied number of trootnento, we voild expect the number of treatments to differ for the two populations: and the impact on evmptome to differ. Diagnosis did influence the delta scores on you note on page 5—6, and perhaps this also influenced the behavioral correlations. The If this table is �""W‘m‘ .m - Dr. Marjerrison We 1.. —2- are planning another "rvuvt—v-Huwntmw —mm«qu-..v.—-—w-- May 17, 1971 study, to look into the delta ECT and its relation to behavior. In 1956 and 1961 I believed the slow waves after seizures were an outward index lateralization of the biochemical changes that underly improvement. Our recent experiences, your report, and the studies by Small, suggest that the EEG changes, like the memory changes, are non—specific indices of brain perturbation, and only indirectly related to the behavioral consequences. Something like the argument about the need for a successful antipsychotic drug to induce parkinsonism a very high correlation but surely not a causal or direct relationship. — The studies should go on. Thanks for the report.
