What is the difference between a developmental delay and a developmental deficit or disorder?

A developmental disability is a disability the person is usually born with, whereas an acquired one could happen at some point in their lives, maybe by an accident or illness.

We study both as one thing with no difference.

Developmental delay is the failure to meet certain developmental milestones, such as sitting, walking, and talking, at the average age.

Acquired is due to an identifiable cause (e.g., trauma, brain bleed, head injury, etc). Developmental is inborn and there is no identifiable cause to the aphasia.

i am not sure if you want to get the real answer then go see a doctor or someone who u think could answer that question beccause i have no idea in the whle intire world
