Over the last six months or so my sister has been in and out of a mental facility for numerous symptoms and recently they have gotten worse. It started with a feeling of chronic deja vu, and anxiety related to it and bi-polar type manic depression. Most recently she has had full seizures, drooling, phantom smells, and vomiting. She is set to have tests done, MRI, CT etc..but I am more leaning towards a mental vs a physical condition. What would you suggest a possible cause of these symptoms could be so I can be as helpful to my sister as I can from 2000 miles away. Desperate in Detroit, for my Sissy in Phoenix. Thank you.
