Global Developmental Delays

Global developmental delays describes when children do not meet their developmental milestones. Generally from the age of 2 months to 5 years old. Although each child is different in their development, milestones are established in order to determine functional skills on age specific tasks.

Delays can occur in the following area:

Gross motor- Involves the use of larges muscle groups such as walking, crawling and standing. May impact children diagnosed with cerebral palsy.

Fine Motor- Small movement in the fingers used for drawing, painting, buttoning, coloring, and shoe tying.

Speech and language delay- A delay in language may be due to motor-oral problems.

Cognitive- Delays can be caused by, infections, ,metabolic, toxic, trauma, and chromosomal abnormalities (Down syndrome, Turner syndrome, etc.)

Social/Emotional Skills- Shows signs of delay in responding and interacting with other people. Common cause may be autism spectrum disorder
