I am a 3rd year phd student in Europe, and my advisor told me that he has a neurological issue.
I believe that this is causing some terrible form of mental deterioration which is affecting my work. Among the things that happened with him:
He has always been forgetful, but lately, he cannot remember any of my explanations. This makes our meetings incredibly frustrating, since I spend all of our meeting time explaining to him the same ideas over and over again. I would be okay with never meeting him, but unfortunately since this semester I turned down one of his ideas and have been meeting with me less, he wrote that I have not been progressing this semester. Therefore I am bound to have these pointless meetings
he has been delaying editing a joint paper of ours for over a year and a half (I would be fine if he wouldn't edit it but he insists on doing this), and during that time his other student improved this result. He suggested that I improve his student's result and I refused to (partially since this is insulting and will not further me).
lately I feel like his memory is deteriorating very quickly. For example, I'm very pregnant and every time he sees me, he says "I totally forgot you are pregnant. When are you due?" But then forgets my answer.
he never checks our joint work and then blames it on me. I have written explanations for him and sent him explanations that others wrote and he never reads them.
if I send him any written text, he will ask to meet so I can make sure that he reads the text and he asks me questions while reading (the same ones I have answered 10000 times before). Then he tells me that it is not his role to read things that I write and is angry at me for wasting his time.
Besides telling me he has a neurological issue, I don't know for sure that it is degenerative, and therefore cannot report him. Since he forgot what I have done in the PhD and therefore is not sure when or if I can graduate (I should graduate next year and look for a postdoc this October).
I have spoken to him about this and he told me that there is nothing wrong extending my PhD. Honestly I want to graduate next year so I will not have to deal with him and so that he won't forget me by the time I graduate so he can write me a good letter.
What are my options if indeed there is a mental deterioration on his part? I don't have a committee or lab director to report to rather the system is built in a way that I report all issues to my advisor (who is my issue). Also, how do I protect myself in case he really loses his mind?
