Re: Bipolar or ? - other possible causes for symptoms...
If you've been working with a psychologist for a long time, she probably has a good idea of any mental disorders that may be going on -- what you want to do is rule out any physical problems that may mimic them.
Make sure you tell the psychiatrist the same thing you told us. Depending on your history and a neurological (physical) exam, they may order a variety of bloodwork, MRI, EEG, sleep study, or something else. It is however doubtful they will order all of it.
