Neurological presentations of conversion disorders in a group of Singapore children.
BACKGROUND
Neurological presentations of conversion disorders in children are not uncommon. Conversion disorders mimicking neurological conditions constitute a group of underdiagnosed conditions.


METHODS
This was a retrospective study of 13 children with neurological presentations of conversion disorders who were admitted to hospital. Patients were followed for 1-4 years.


RESULTS
Paralysis was the most common neurological symptom, patients presented with multiple, complex conversion symptoms and other neurological symptoms such as seizures and headache. The affected children underwent complete physical, neurological examination and psychological evaluation. Investigations included blood tests, cranial imaging and electroencephalography. Most common external environmental factors detected were school stress and change in family situation. Five of 13 patients had family members who were reported to have medical conditions with presentations similar to patients' neurological and psychological problem. All the patients were admitted, five patients required multiple admissions. Ten patients eventually had good outcome in terms of academic grades and social functioning.


CONCLUSIONS
Diagnosis of conversion disorders mimicking neurological conditions can be challenging. There is a need to heighten awareness of this entity for early recognition and diagnosis. Awareness of this entity coupled with a high index of suspicion can facilitate accurate and earlier diagnosis.
