Cerebral Palsy maybe/maybe not

The PVL worst area is near where tracts representing the lower legs are passing by. The tracts from the body form a boomerang shape in cross section horizontally. That shape carries certain nerve fibers away from low flow danger.

As the flow drop worsens, the damage spread will bring in wider representation of the body and even a bit from the hands. Nestled in the hollow of the boomerang, however, are other structures which are associative. As hands get more involved (the scope of injury larger) the chances that these associative areas will also suffer, increases. For that reason, in this group there is an association between more hand involvement and mild learning difficulties. The more severe PVL cases can have considerable hand and arm involvement, perhaps only on one side. Again a flow issue so it can vary with local vascularity unlike O2 debt which does not respect spatial boundaries.

PVL four limb involvement is unlike that seen in total body involvement as the kind OF neurological injury is different and where it resides is different.
