AB Autism  spectrum  disorder  (ASD)  is  a  heterogeneous  developmental  neuropsychiatric  condition  characterized  by  two  core  symptom  criteria:  (1)  deficits  in  social  communication  and  social  interaction;  and  (2)  restricted  patterns  of  repetitive  behaviors  and  interests  or  activities.1  Previously,  ASD  was  not  a  formal  diagnostic  term.  Autistic  disorder  was  included  under  the  broader  category  of  pervasive  developmental  disorders  (PDDs)  with  other  neurodevelopmental  conditions  characterized  by  impaired  social  behavior  and  communication  along  with  restricted  interests  and  repetitive  behavior.  Those  additional  conditions  included  Asperger’s  disorder,  Rett’s  disorder,  child  disintegrative  disorder  and  PDD,  not  otherwise  specified  (NOS).  In  DSM-5,  autistic  disorder,  Asperger’s  disorder,  and  PDD  NOS  have  been  subsumed  under  the  category  of  ASD  while  Rett’s  disorder  and  childhood  disintegrative  disorder  have  been  removed  and  are  not  considered  to  fall  within  the  rubric  of  ASD.  In  DSM-5,  if  ASD  symptoms  are  clinically  present  in  the  setting  of  a  genetic  condition  such  as  Rett’s  disorder,  the  individual  is  diagnosed  with  ASD  with  the  specifier,  “associated  with  a  known  medical  or  genetic  condition  or  environmental  factor.”
