What is Pervasive developmental disorder not otherwise specified?
Children with PDD-NOS may vary in their symptoms and severity of their symptoms as it is classed as a spectrum disorder. Children with PDD-NOS will have difficulties with two main areas of development which include social interaction and communication skills.
Children with PDD-NOS may experience the following difficulties or symptoms:
- Unable to make genuine connections with peers at school.
- Difficulty reading non-verbal cues e.g. facial expression and tone of voice to convey emotion.
- Inappropriate responses to emotional communication e.g. laughter and crying.
- Thinking very literally and not always understanding humour or sarcasm.
- Language delay
- Limited vocabulary (words they know and say)
- Repetitive or restricted language
- Poor non-verbal communication (eye-contact and facial expression)
