Thaddeus H.: The setting is very, very difficult. Interviewer: Okay. What do you mean by that? Thaddeus H.: I make protocols, write down every day exactly. You can't keep that in your head. And Mr A [name] is our doctor. He gives us a free hand in varying the amount and the time and so on. And he can only make recommendations to us and say, "try it once." I also realise that, every Parkinson's is different. Interviewer: Yes, that's true. Thaddeus H.: Every person reacts differently. That is very, very difficult. But that is also [the case] with these medicines. [...] In this respect it probably makes no difference. But we can do that ourselves. And I am always on site with the woman and then I can react at short notice. [...] Thaddeus H.: I have to say, [...] I have been doing the protocols for about six weeks now. Interviewer: Ah, [...] okay. Thaddeus H.: Yes, and I haven't [found] the right attitude yet, still not.
