- Speech delay is delay in the acquisition of spoken language.
- Language is a system of symbols through which humans communicate thoughts, feelings and ideas. It has 3 components: Receptive, expressive, and visual language.
- Receptive language is the ability to process and understand language.
- Expressive language is the ability to communicate through speech, written, or formal sign language.
- Speech delay can be primary, as in Developmental Language Disorder (DLD), or secondary to another condition. DLD is impaired speech/language in an otherwise normally developing child who lacks signs or stigmata of other conditions.
- Constitutional language delay, a retrospective diagnosis, is language delay associated with eventual achievement of normal speech and language milestones by school age. There are no subsequent difficulties with learning to read or write.
- Expressive language disorders include the following:
- Verbal dyspraxia: Little speech produced with great effort, very dysfluent, single words most commonly.
- Speech programming deficit disorder: Poorly organized difficult-to-understand speech
- Mixed receptive and expressive disorders:
- Verbal auditory agnosia: Impaired ability to decode speech, resulting in a severe expressive impairment. Can often learn language visually.
- Phonologic/Syntactic deficit disorder: Most common type of DLD. Comprehension exceeds spoken ability. Speech is dysfluent, grammatically incorrect with short utterances.
- Most frequent causes of speech delay:
- Hearing loss
- Developmental language disorder
- Autistic spectrum disorder
- Mental retardation
