Conversion Disorder Masquerading as Severe Progressive Neurological Deterioration in Childhood

Abstract

Diagnosis of neurological conversion disorder is difficult. Considerable overlap in symptomatology occurs with progressive neurological degenerative disease, pervasive refusal syndrome, depressive illness, chronic fatigue syndrome, and other conditions. Conversion symptoms can also coincide with organic neurological disease. Successful management requires a sensitive, confident, multidisciplinary approach. Multiple or repeated investigations can be counterproductive in resolving symptoms. This report describes three children, one male and two female, aged between 9 and 10 years, who were referred for evaluation of progressive neurological symptoms. Each progressed to a completely dependent state within 8 weeks of referral, requiring nasogastric feeding and total assisted care. A convincing psychosocial trigger was not identified in any case. Improvement occurred only when investigations were ceased and rehabilitation commenced. Long-term follow-up has revealed an excellent outcome for all three children.
