Probably not much, because it’s basically just prolonging the suffering and it’s entirely futile. I think Luna’s shunt was done more for Robyn than any real benefit to Luna
Here is a case study with imagery of the brain.
Here’s another study
But in this study the newborns developed multicystic encephalomalacia due to “shaken baby syndrome” - basically any severe head trauma (like getting squeezed in the birth canal and being deprived of oxygen) can cause it in newborns.
Sort of interesting to note that many cases of this condition occur after birth, within in the first few weeks, due to head trauma. One case mentions a 6 week old baby falling off a bed and being unconscious for 30 minutes as the suspected cause. She was Dx at 6 months.
Could be either, but how much more downhill is there for Luna to go? She’s sort of run out of road.
