Changes in Panayiotopoulos syndrome over time.

Area of Science:

• Neurology
• Epileptology
• Pediatric Neurology

Background:

• Panayiotopoulos syndrome (PS) was first described in 1989 as an idiopathic epilepsy syndrome.
• It was characterized by nocturnal seizures, tonic eye deviation, and vomiting, suggesting occipital lobe involvement.
• The syndrome has since been recognized as a benign, age-related focal epilepsy with an expanding clinical spectrum.

Purpose of the Study:

• To review the evolution of the understanding of Panayiotopoulos syndrome.
• To highlight the expanded clinical manifestations beyond the initial description.
• To identify unresolved issues in the diagnosis, genetics, and pathophysiology of PS.

Main Methods:

• Literature review and synthesis of existing studies on Panayiotopoulos syndrome.
• Analysis of clinical, electroencephalographic, and genetic data from reported cases.
• Discussion of theoretical and practical challenges in PS management.

Main Results:

• The clinical spectrum of PS has broadened significantly, encompassing diverse seizure types.
• While initially linked to occipital lobe epilepsy, PS now includes a wider range of presentations.
• Prognosis remains generally excellent, consistent with its classification as a benign epilepsy.

Conclusions:

• Panayiotopoulos syndrome is a recognized benign childhood epilepsy with evolving clinical features.
• Further research is needed to address unresolved diagnostic, genetic, and pathophysiological questions.
• Clarifying these aspects will improve the understanding and management of this common epilepsy syndrome.
