The spectrum of XXXX ( @entity19461 ).

@entity1 @entity154 @entity3308 @entity2978 @entity19461 @entity39 @entity8482 @entity16 @entity22212
The @entity19461 consists of @entity22212 with @entity154 . No single pathophysiologic hypothesis accounts for all aspects of the syndrome. We present six cases which manifest a very broad spectrum of associated @entity16 . Postmortem examination was performed on two cases. Midline @entity3308 @entity39 was evident in one while the other had subtle @entity3308 . The four other @entity1 have demonstrated fixed deficits on follow-up examinations. Improvement in @entity3308 evoked potential waveforms has occurred in three cases, but the significance is uncertain. Many of the cases were delivered by caesarean section because of failure of labor to progress, and had associated @entity2978 and @entity8482 . These features suggest that a defect is established in utero. Only one @entity1 , born prematurely, may have suffered some perinatal @entity3308 insult. @entity22212 is a heterogenetic entity which can affect the nervous system in many different ways.
