If we consider together the common features of these three cases, we see that they resemble stupors only in the presence of inactivity and apparent apathy. It is true that death appears in the ideational content but not with that prominence, bordering on exclusiveness, which characterizes such delusions in the true stupors. These three patients give one the impression of being absorbed in thoughts that have many variations. It seems as if they had difficulty in grasping the facts of the environment, while feeling at the same time the vividness of the changing internal thoughts, hence a confusion develops which is either subjective, objective, or both. It is probably the introversion of attention which gives rise to the apparent apathy, because normal emotions emerge as part of our contact with reality around us. This lack of contact with the environment leads also to inactivity. If one’s attention and interest is turned inwards, there can be no evidence of mental energy exhibited until the patient is roused to contact with the people or things about him. It is noteworthy that in these cases emotional expression emerged when the patients were stimulated to some productiveness in speech. These conditions really constitute a different psychosis in the manic-depressive group, essentially they are perplexity states such as have recently been described by Hoch and Kirby.[7] Not infrequently we see exhibitions of this tendency in what are otherwise typical stupors. For example, Mary F. (Case 3) (the third case to be described in the first chapter), showed for a few days after admission a condition when she was essentially somewhat restless in a deliberate aimless way. At the same time she looked dazed or dreamy. With this restlessness she appeared at times “a little apprehensive.” Although she spoke slowly, with initial difficulty she answered quite a number of questions. Her larval perplexity was evidenced by the doubt expressed in a good many of her utterances, such as, “Have I done something?” “Do people want something?” “I have done damage to the city, didn’t I?” When asked what she had done, she said, “I don’t know.” She asked the physician, “Are you my brother?” and when questioned for her orientation said, “Is not this a hospital?” The atmosphere of perplexity also colored the information which she did recall correctly; for instance, when asked her address, she said, “Didn’t I live at ----?” then giving the address correctly.
