emotional lability - definition of emotional lability in the Medical dictionary - by the Free Online Medical Dictionary, Thesaurus and Encyclopedia.

I am posting a few links, that discuss, 'emotional lability'. What you describe, is concerning, and perhaps, she'll still need a pdoc, in her corner, however, what you describe, seems to be speaking to a few of us, as something a lot more, than just psychiatric.

Just because, the initial MRI's didn't seem to reveal, any abnormalities, doesn't mean that a follow up, isn't in order, especially now, with the emotional changes. Reading, MRi's can be very difficult. And sometimes, if it's the radiologist reading them, and handing over a report, the doctor may not have a chance, to thoroughly review it, on closer inspection, not saying, that happened, but it's worth following up on.

I know, that with many MS patients, lesions, may not always appear, and then later they appear. Some appear and disappear and reappear, again. I am not sure, about lyme disease, how that shows on scans. I know, there are some parkers for a stroke, but, depending on location, of abnormalities, the brain is just one very complex organ.

Plus, imo, it may be a little 'easier' to convince her, to see a neuro, than a shrink...
