A small but significant improvement in cognitive functioning on the drug was not accompanied by significant changes in rCBF for the group as awhole. However, when the analysis was repeated excluding the only patienty who showed no clinical respopnse to the drug a significant increase in rCBF was seen to the right posterior temporal area. This preliminary study shows that some caution is necessary when interpreting studies of rCBF as changes in cognitive functioning may not always be accompanied by parallel changes in rCBF. Separate analysis of drug responders and non-responders may be a fruitful area for further research.
