Last monday my father slipped into...pretty much a coma. We haven't been able to find a reason for this. The drs are telling us that he has an infection at the brain stem, and swelling of the brain. But, they cannot tell us what is causing this. They have done so far 2 spinal taps, blood cultures, eeg, mri, the works, and still no cause to where the infection came from. They say that they are pretty sure that it was caused by either a bacteria, or virus, they just can't seem to find out which. A few years back, he was diagnosed with Bipolar disease. None of us (his 4 daughters) thought that was a correct diagnosis. He never showed any symptoms of mania stages, and was acutally a very calm individual. Shortly after being diagnosed with this disease, he developed what his Drs called convulsion disorder. He NEVER EVER had seizures before this diagnosis. He has progressively gotten worse. Headaches, memory loss, passing out, not steady on the feet. Could a misdiagnosis be a culprit? Could mixing wrong meds that he didn't need to be on in the first place cause this? Does anyone have any directions they can point me in? Anything can help at this point.
