Identifying the cause of intellectual disability is not easy in most cases. Intellectual disability can have various causes, including genetic factors, prenatal exposure to toxins or infections, complications during birth, and postnatal factors such as trauma or illness. Determining the exact cause requires a thorough evaluation, including medical history, genetic testing, and assessments of cognitive and adaptive functioning. It can be a complex and challenging process, and in many cases, the cause may remain unknown. Therefore, the statement that it is easy to identify the cause of intellectual disability is incorrect.
