Amie Miller, 15, was taken to Basildon Hospital A&E in November 2008 after suffering headaches while studying for her GCSEs.
A jury returned a narrative verdict, saying that the medics had seriously failed to meet Amie's needs by failing to carry out basic checks, administering inappropriate treatment and failing to properly communicate with one another.
Speaking afterwards, Amie's family told how she was a promising student who had dreamed of becoming a paediatrician.
