Global Developmental Delay ● individual fails to meet expected developmental milestones in several areas of intellectual functioning ● Individuals who are unable to undergo systematic assessments of intellectual functioning, including children who are too young to participate in standardized testing ● Under the age of 5 Unspecified Intellectual Disability (Intellectual Development Disorder) ● Who have significant intellectual or general developmental delay or disability and who cannot be reliably assessed ● Used in persons over age 5 Communication Disorders Language Disorder Language Disorder is a child’s delay in using spoken and written language which is characterized by small vocabulary, grammatically incorrect and trouble in comprehension.


● Symptoms onset is in the early developmental period

Childhood-Onset Fluency Disorder ● Stuttering ● Disturbances in the normal fluency and time patterning of speech that are inappropriate for the individual’s age and language skills Social (Pragmatic) Communication Disorder ● Deficits in using communication for social purposes, such as greeting and sharing information, in a manner that is appropriate for the social context ● Impairment of the ability to change communication to match context ● Difficulties following rules for conversation and storytelling ● Difficulties understanding what is not explicitly stated Unspecified Communication Disorder Autism Spectrum Disorder Autism Spectrum Disorder ● persistent deficits in reciprocal social ● With or without Major characteristics of autism spect r um diso r de r:
