Question
A five-year-old child is experiencing difficulties in language expression and walking, suspected of having intellectual disability. How can intellectual disability patients be typically determined?
Answer
The determination of intellectual disability usually involves observing facial and physical abnormalities, such as the so-called “international face” with widely spaced eyes, slanted eyes, and a flat nose bridge that may be present in congenital idiocy patients. Additionally, hydrocephalus patients may have an abnormally large head circumference, while microcephaly infants have particularly small skulls. Patients with hypothyroidism may be especially short in stature, and those with phenylketonuria may have abnormally pale skin and very light-colored hair. Poor responsiveness to the environment is also an indicator. It is recommended to visit a regular hospital for examination to clearly determine the cause of the disease and receive appropriate treatment.
