The stalemate position.

The psychosurgical operation of stereotactic subcaudate tractotomy can be a highly effective treatment for chronic and intractable affective disorders. We have lately given increasing attention to cases where the depressed mood appears to lift although there is little improvement in social function. In these cases there has been a failure of rehabilitation and the complexities of this process post-operatively are discussed. In addition, relatives report in some 10% of cases "personality changes" after the operation which are not perceived in this way by an independent medical assessor and these observations seem to depend upon relatives mis-interpreting the resumption of pre-morbid personality function after long illnesses as undesirable side-effects. Case histories illustrating the problems are described. Treatment and rehabilitation strategies are outlined.
