Attacks of amnesia, well known to those who work with mentally ill people (at any level, not only the most serious) are also the consequence of anaesthesia of feeling. It is well-known how a memory is more strongly maintained when it is emotionally invested. In emotional anaesthesia therefore the use of memory is also strongly limited, or rather memories themselves are subject to anaesthesia (so that we speak of unconscious memories: but it would be closer to the truth to consider them as "anaesthetized").
Anyone living with a mentally ill person therefore suffers more or less frequent moments of strong amnesia, as a result of induction, but almost never related to the same memories as those emotionally significant to the ill person. The result is a real memory disturbance: the person knows that they must do something important, but they don't remember what it is.
So deadlines pass and important appointments are missed. But the most upsetting aspect of the effects of induction is in the way they modify the same memories, especially if even remotely connected with the story of the ill person. So it is discovered, in the course of analysis, how for long periods unsustainable justifications were made as to the patient's condition, based on facts and events of the past "modified" - thanks to the amnesia - just enough to make them fitted for that strange use.
The most frequent usage concerns the "faults" that one or other members of the couple or both attribute to each other or themselves. So the mother emphasizes her fear before the birth, to accuse herself of "not having wanted the child"; or else the father exaggerates his working commitments during the child's infancy so that he can see himself as the absent parent, when in reality he thought only about the child, and his concern that he would have everything.
The majority of cases of psychosis have their origins in the early years, if not months of life, and furthermore the cause is usually an early interference in the primary relationship: perhaps time spent in an incubator, or in a cot for ultraviolet light, or even in the nursery of a hospital between one feed and another (not to mention intensive treatment for infections or surgery, if the new born baby's life was endangered). It is most improbable that the response of anaesthesia of feeling is determined by the parents. So why such an accentuated feeling of guilt on their part?
