We just got the images from Macayla's latest MRI. This video is a bit fuzzy because it had to be small to upload, but it will show a comparison of all her MRI's from approximately the same cross section location.
Notice how the natural open areas (ventricles) within the brain are opening up more and getting larger. The least effected area of the brain is the temporal lobes (bottom, toward the front) and that would help explain Macayla's memory being as good as it is. As I look at these images, I am amazed at how much she can do. It is amazing to think that a person can have a tumor the size of grape in their brain and it cause so much havoc. By that standard, you would think that when more than half of the brain has atrophied, that a person would be dead. But, amazingly, Macayla still laughs, makes vocal noises, listens to us when we talk to her, knows who we are, and has some of the cutest stretches in the morning when she wakes up. I love to watch her yawn and stretch her arms over her head when she is waking up. It gets both of our mornings off to a good start.
