[Neurological appraisal of children and adolescents with psychotic symptoms].
BACKGROUND
Psychotic manifestations in childhood are not infrequent, yet the existing literature dealing with the neurological appraisal of children and adolescents with a clinical picture of psychosis is very scant.


OBJECTIVE
To conduct a non-systematic review of the literature that provides an answer to these three questions: When must a neurological appraisal be performed in a child with psychotic traits? What medical conditions can include signs and symptoms of psychosis in their development? And, what diagnostic procedure should be followed?


METHODS
The diseases that can present psychotic symptoms at onset or during their course are reviewed and grouped by pathologies: inborn errors of metabolism, genetic diseases, autoimmune and infectious diseases, malformations of the central nervous system, epilepsy, vascular pathology, rheumatologic processes, brain tumours, and psychoactive substances and drugs. A diagnostic regimen is proposed in which both the information obtained from the anamnesis and examination and the findings from each of the diagnostic tests are evaluated.


CONCLUSIONS
A huge number of processes can display psychotic symptoms during their course and the key information offered by the anamnesis and examination must be taken into account. This review can help neuropaediatricians and other specialists perform a more systematised appraisal of children and adolescents with psychotic signs and symptoms.
