Ester O.: He is no longer allowed to operate the device himself. They have blocked it. Interviewer: So the neurologist. Ester O.: Yes, from the P [hospital name]. Interviewer: So he used it a bit too much? Ester O.: Yes. He didn't stick to what he was told. They stopped it, then he said, "maybe zero point five more" or something. And then he just stopped two or three and [...] the doctor just said that it wasn't possible. Interviewer: And what happened when he stimulated too much? What happened? Ester O.: Then the over-movements came again. [...] And then he turned it down again and up again and every hour four or five times. That's not possible. Interviewer: But they were over-movements, like before the operation, so from the body or [was it] psychological, so hyperactivity or something? Ester O.: Yes, he was hyperactive. Interviewer: But there was no hyperactivity, like before the operation? Ester O.: No. [...] And then he regulated down [the device] again [...]. And they had difficulties to adjust him so that it's normal. And now sometimes he tries a little bit more, the neurologist, [...] but my husband, he would like to have more and so. And the neurologist says, "no, he gets aggressive again." Interviewer: Is he still aggressive? Ester O.: Yes. If too much is adjusted, he becomes aggressive. Interviewer: Yes, of course. Ester O.: It goes to the aggression centre [in the brain] [...], he said so.
