:: PERVASIVE DEVELOPMENTAL DISORDER-NOT OTHERWISE SPECIFIED
(PDD-NOS)
Sometimes children do not ‘fit in’ to any of the ASD’s described above. However, they do manifest an impairment in the development of social interaction, or non-verbal or verbal communication skills, or stereotyped behaviors. These behaviors manifested may not meet the criteria for any of the ASD’s due to late onset, or insufficient characteristics specified each ASD. It is said then that the child has PDD-NOS.
