Differentiating [Disease name] from other Diseases

1. Neurocognitive disorders – there is loss of cognitive functioning in these cases.
2. Specific learning disorder and language disorders – compared to individuals with ID, these individuals have deficits in communication and learning aspects but with normal intellect and adaptive function.
3. Autism spectrum disorder – social development and language deficits are the hallmark of autism spectrum patients and have normal motor development.

Possible hearing and visual impairments should be ruled out in diagnosing intellectual disability.
