Periventricular Leukomalacia (PVL) is a neurological condition that affects premature infants. It is characterized by damage to the white matter that surrounds the cerebral ventricles, the regions in the brain that are critical for cognitive function and motor control. PVL is primarily caused by complications during premature birth. Typically, due to insufficient oxygen or limited blood flow to delicate brain regions, the damage can be extensive.
