Peripheral Neuropathy in Adolescence With Anorexia Nervosa: A Rare Yet Significant Clinical Manifestation.

The neurological complications of anorexia nervosa (AN) remain poorly understood. In the pediatric population, rare cases of isolated nerve involvement-most frequently peroneal nerve-or sensory and/or motor neuropathies have been reported. This case report describes a 16-year-old female adolescent with restrictive-type AN who developed left foot drop due to peroneal nerve injury in which both mechanical nerve compression and malnutrition were implicated as contributing factors. The diagnosis was confirmed through detailed history-taking, physical examination, and electromyographic studies. Early initiation of electrotherapy and targeted exercise programs-prior to full weight restoration-combined with psychiatric and nutritional management within a multidisciplinary approach led to complete clinical recovery. This report discusses the evaluation, differential diagnosis, and multidisciplinary treatment strategies for peripheral neuropathies associated with AN, supported by a review of the relevant literature.
