CVI can make a child very jumpy and sometimes frightened, or terrified, even causing a full meltdown.
Think of a time someone has jumped out at you and, made you jump, maybe as a prank for fun when you were a child. That momentary feeling that made you physically jump or scream, was part of the same brain reaction, fight or flight, described in the previous page (anxious).
Your child's frightened or jumpy behaviours are most likely associated with a fear of physical injury, quite literally being hit by something. That is likely what their brain has anticipated and responded to, to make them jump or scream. It is a primitive protective reaction your child will have no control over.
We move all the time, just turning your head creates movement, and your brain calculates that movement. It is very common for children with CVI to have problems with these calculations, they are the same calculations that makes them sometimes clumsy. What happens as a result is that the brain does not accurately put things in the right place, meaning a few things can happen for your child:
These frights can leave your child feeling anxious about going out, particularly to busy places.
Anything that means that the fight or flight reflex is regularly activated, as is the case here, can leave your child feeling physically very tired, possibly a bit lethargic. They then need rest and sleep.
