Abstract
Paroxysmal tonic upgaze deviation (PTU) is a rare neuro‐ophthalmological disorder with onset in infancy or early childhood. It consists of episodes of sustained, conjugate, upward deviation of the eyes, down beating saccades in attempted downgaze, apparently preserved horizontal eye movements, frequent association with mild ataxia or clumsiness at time of illness, normal metabolic, electroencephalographic and neuroradiological findings. Symptoms are frequently relieved by sleep and can be exacerbated by fatigue or illness. Although PTU generally tends to disappear spontaneously within a few months or years, subsequent case reports have demonstrated the heterogeneous nature of the syndrome with respect to outcome. To date, the pathogenesis of the condition is still unknown. We present a new case of PTU with ataxia occurring in an otherwise healthy child, as documented by video recording of the phenomenon.
期刊介绍:
Epileptic Disorders is the leading forum where all experts and medical studentswho wish to improve their understanding of epilepsy and related disorders can share practical experiences surrounding diagnosis and care, natural history, and management of seizures.
Epileptic Disorders is the official E-journal of the International League Against Epilepsy for educational communication. As the journal celebrates its 20th anniversary, it will now be available only as an online version. Its mission is to create educational links between epileptologists and other health professionals in clinical practice and scientists or physicians in research-based institutions. This change is accompanied by an increase in the number of issues per year, from 4 to 6, to ensure regular diffusion of recently published material (high quality Review and Seminar in Epileptology papers; Original Research articles or Case reports of educational value; MultiMedia Teaching Material), to serve the global medical community that cares for those affected by epilepsy.
