Because these anatomical features persist into early childhood, the dura may remain similarly vulnerable to bleeding beyond the newborn period. Indeed, both birth-related bleeds and those attributed to shaking are most often located in the folds of membranes covering the brain that have more and larger blood vessels at this age than later in life.
由于这些解剖学特征一直持续到早期童年，因此脑膜可能一直保持类似的易出血状态直到新生儿阶段后。事实上，不管是与出生有关的出血，还是被归因于震动的出血，通常都位于包裹大脑的膜的褶皱处，这些部位的血管在初生时比日后更大。
