An update and a request for any additional information that anyone might have. The following is kind of cut and pasted from an email my sister sent me:
They saw the pediatric neurologist last Friday. They didn't have an appointment until July 28, but the neurologist wanted to see her earlier -
Basically, she's worried that my niece either has a progressive brain injury (lesion, tumor, enlarged blood vessel) or progressive spinal injury. At this point, they're hoping that she 'just' has C.P.
On Monday, she'll have a brain MRI - this will show the Dr. if she has any of the above brain injuries. If the MRI is negative, then she'll have a spinal MRI at a later date (they're not doing them at the same time because it involves a lot more anesthesia to do both than just the head and because the Dr. thinks that it's much more likely that it's in the brain than the spine because it involves her hand). If the MRI is positive then she'll refer them to 'her husband, the neurosurgeon'. She said not to change their travel plans - if the MRI is negative, then they have a little leeway on getting the spinal MRI done.
If both MRIs are clear, then she'll have the diagnosis 'spastic hemiparesis, origin unknown'. Technically, she said, it wouldn't be cerebral palsy because C.P. describes the origin and because it wasn't noted in a level 3 ultrasound and because nothing unusual happened at birth, it wouldn't technically be C.P. (those are the two origins of C.P.) But basically, for all intents and purposes, it's the same thing. (spastic hemiparesis is also a C.P. diagnosis). That's another reason why she's worried about lesions, etc. Because she thinks this is something that happened after she was born (again, because it wasn't noted at birth or during the level 3 ultrasound).
The neurologist recommended upping the OT to 2x/week -- she's doing 1x/week now and also recommended adding aquatherapy, but my sister doesn't know if her health plan will cover it (just a note: one of her relatives will). My sister is very very happy with the neurologist.
Thanks for any and all info. I'm a bit scared to look things up at the moment. My sister is holding off on doing it until after the MRI, also.
