| - | * Normal variations in language | + | * **Normal variations in language** |
| * Language disorder needs to be distinguished from normal developmental variations, this is hard to decipher before 4 years of age. Regional, social, or cultural/ethnic variations of language must be considered before giving a diagnosis of language disorder. | * Language disorder needs to be distinguished from normal developmental variations, this is hard to decipher before 4 years of age.

| - | * Hearing or other sensory impairment | + | * **Hearing or other sensory impairment** |
| * Hearing impairment should always be excluded first as the primary cause of language problems. Language deficits can be associated with a hearing impairment, other sensory deficit, or a speech-motor deficit. For example, individuals with Central Auditory Processing Disorder (CAPD) can have language deficits. Only when the language deficits are in excess of what is expected, should a diagnosis of language disorder be made. | * Hearing impairment should always be excluded first as the primary cause of language problems.

| - | * [[child:intellectual-disability|Intellectual disability]] | + | * **[[child:intellectual-disability|Intellectual disability]]** |
| * Language delay is often the presenting feature of intellectual disability, and the definitive diagnosis may not be made until the child is able to complete standardized assessments. A separate diagnosis is not given unless the language deficits are clearly in excess of the intellectual limitations. | * Language delay is often the presenting feature of intellectual disability, and the definitive diagnosis may not be made until the child is able to complete standardized assessments.

If there are symptoms of seizures, a detailed [[neurology:approaches:seizures|neurologic and seizure history]] and diagnostic investigations should be ordered (e.g. - [[neurology:investigations:eeg|]]) | * Language disorder can be acquired in association with neurological disorders, such as epilepsy, stroke, [[neurology:approaches:aphasia|aphasia]], or Landau-Kleffner syndrome (also known as infantile acquired aphasia).
