Diagnostic Considerations
In addition to the differential diagnosis (see below), other problems to be considered include the following:
- Mental retardation (idiopathic or due to a known cause, such as lead poisoning, aminoacidopathy, iodine deficiency, or hypothyroidism)
- Brain tumor
- Heavy metal intoxication
- Insecticide overdose
- Long-chain or medium-chain fatty acidopathy
- Neurodegenerative disorders
- Psychoactive substance poisoning
- Seizure disorder
- Unusual presentation of neurologic manifestation of
- HIV/AIDS, Landau-Kleffner syndrome (LKS), or adrenoleukodystrophy
- Rett syndrome
- Schilder syndrome or other progressive central nervous system (CNS) storage or metabolic disorders
- Aminoacidurias
- MECP2 gene mutations
- Semantic pragmatic syndrome
- Multidimensional impairment
- Hydrocephaly
- Pathologic demand avoidance (PDA) syndrome
- Nonverbal learning disorder
- Teratogenicity[18, 19]
