We are so confused. When we saw Mum on Thurs, she said that she couldn't hear anything, even with her hearing aids in - she said they need new batteries, I said I didn't think so as we had changed them last week and the carers disconnect them at bedtime - I checked them both and they don't look dirty, nor do her hears, I left telling her I would contact the audiology department on Monday. I rang her today and she spoke to me really well, answering my questions etc with no problem at all, but once I mentioned her hearing aids, she completed changed, said they weren't working and she couldn't hear me and reverted back to being deaf - is this normal- similar things have happened eith her eyesight - she says she cannot see anything at all but then out of the blue will pick something up and read it - has anyone else experienced anything like this?
