There does seem to be some escalation or change in her symptoms which is worrisome. It’s difficult to know what might be causing it. There are several possibilities including a psychotic disorder like schizophrenia, but it can also be related to stress, PTSD, or her mild brain damage. There may be other possibilities as well. Without a mental health evaluation, it’s difficult to know with certainty what the problem might be.
What’s most important is encouraging her to report these symptoms to her treating physicians. They will likely adjust her medications in an effort to target these new symptoms. Her symptoms can likely be controlled with medication. It’s better to treat these symptoms sooner rather than later to prevent them from developing into a psychotic episode or disorder.
Because of her symptoms, it’s becoming increasingly difficult for her to trust the people around her, even those close to her. This underscores the importance of her reporting her symptoms and having her medication adjusted. You mentioned wanting her to go to therapy. That might help her in the future, if she were willing to go, but right now what is most important is her consulting with her treating physician about these symptoms. That will give her the best chance of preventing these symptoms from worsening.
Finally, if she won’t report her symptoms to her doctor you can report them for her. Privacy laws prevent her doctor or treatment team from discussing her case with you (unless she has given them explicit permission to do so) but there is nothing that prevents you from contacting them to report your concerns. At least they’ll know what’s going on and might be able to help. Please feel free to write again with additional questions. Please take care.
