Summary Attention is drawn to a clinical syndrome apparently associated with a persisting transference following a previous interrupted psychoanlysis or some other intensive therapeutic relationship. Two classical cases are reviewed through a long-term follow-up: the case of Anna O. and the case of the Wolf-Man. Other literature is discussed, about termination of psychoanalysis and transfer of psychotherapy patients, about second analyses and whether the original analyst can resolve his patient's transference completely. The bulk of the paper concerns thirty patients seen in diagnostic interviews, in psychotherapy or in full psychoanalysis. Three sample case histories are presented. The patients have been classified as manifesting (a) minimal unresolved transference, (b) unresolved transference with insight, or (c) unresolved transference without insight. Symptoms presented by about half of the third group have been tabulated for all three groups and described. A full constellation of symptoms is as follows: after a period of hypomanic optimism, absence of feelings, then hypochondriasis, fatigue and weakness, lack of initiative and indecision; phobias, especially for doctors and medication and for the new analyst's couch; insomnia, forgetting or not understanding dreams, and difficulties in communication, especially in social groups or with the previous analyst. Some prevailing circumstances at the onset of symptoms have been tabulated and there has been an unsuccessful attempt to correlate the symptoms with previous personality structure. The course of most of these 30 patients has been followed up for five to ten years after they were first seen after the original, or a second, analysis. Spotty experience has also been reported with instances of these clinical phenomena following other therapeutic relationships which were prematurely terminated. The dynamics of these phenomena have been discussed as manifestations of grief reactions to separation from the original psychoanalyst or therapist. Aspects of psychoanalytic technique and of counter transference considerations have been mentioned in relation to literature. These phenomena may intrude as complications in psychoanalytic education, but this paper aims merely at drawing attention to their use in treatment when they are threatening the pursuit of completion of a process which was aborted before optimum development. Appreciation is due to several analysts who have made suggestions about the manuscript of this paper or a precursor of it. A few years ago Dr. Helen McLean and the late Dr. George Mohr contributed many helpful criticisms of an earlier version. Dr. Therese Benedek, in a lecture, stimulated in the author the idea of laying such a manuscript aside for a few years before revising and updating it. More recently Dr. Fred Kapp, Dr. maurice Levine and Dr. Paul Ornstein have improved this edition for publication.
