6A00.4/F70-F79 Disorder of intellectual development, provisional



The exact cause of Disorder of Intellectual Development (DID) is unknown, but it is believed that a combination of genetic, environmental, and medical factors contribute to the development of DID. It may be caused by chromosomal abnormalities, genetic syndromes, or environmental factors such as prenatal exposure to drugs, alcohol, or toxins.


Diagnosis of DID is based on a review of medical history, physical exam, and psychological testing. Additional tests, such as imaging studies or genetic testing, may be used to help diagnose DID.

Differential diagnosis

DID can be confused with other intellectual disabilities, such as autism or Down syndrome, or developmental delays due to other medical conditions or environmental factors.


Treatment for DID is aimed at helping the individual manage the symptoms and maximize their potential for reaching their personal goals. Treatment options may include educational interventions, behavioral therapy, and medications.


The prognosis for individuals with DID is highly variable and depends on the individual’s specific needs. With early intervention and appropriate treatment, individuals with DID can make progress in their development and reach their personal goals.
