(A fixed false belief not supported by reality, and often caused by a faulty memory.) For example saying she covered as a teacher and was told she was better than the teacher. And they wanted her to doing the job for longer. When she just was an unqualified lunchtime assistant, She also used to act as a passenger in the taxi taking children to school. Therefore couldn't even have physically covered the lesson. Another example she talks about lots of different cooking things she used to do and how she went to night school for cooking. Whereas she went to night school to do art and is more of a heat up type of cook. I think my dad is ignoring the situation and isn't someone who would ask for help. He is 80 soon. My mum says her balance isn't great. But otherwise there are no more symptons. My husband and daughter just thinks she is nearing end of life and regretting lack of achievements in life. As their only child, I just want to make sure I am identifying potential signs of alzheimers/dementia. Or other types of old age mental health conditions. I would appreciate feedback from elder care experts.
