The benign partial nonrolandic epilepsies
1Pediatric Seizure Clinic and EEG Laboratory, Beilinson Medical Center, Petah Tikva, Israel.
Insights
Benign partial epilepsies, beyond rolandic epilepsy, are genetically determined childhood disorders. These conditions, often diagnosed after 18 months, typically present with brief seizures and resolve before adulthood.
Area of Science:
- Pediatric Neurology
- Epileptology
- Clinical Neuroscience
Background:
- Rolandic epilepsy is the sole recognized benign epileptic syndrome.
- Other forms of benign partial epilepsy exist in neurologically healthy children.
- These syndromes are age-dependent and genetically influenced.
Purpose of the Study:
- To detail non-rolandic benign partial epilepsies.
- To review the current literature on these conditions.
- To highlight their characteristics and diagnostic criteria.
Main Methods:
- Literature review of benign partial epilepsy syndromes.
- Analysis of clinical features, EEG findings, and genetic factors.
- Comparison of rolandic epilepsy with other benign forms.
Main Results:
- Several benign partial epilepsies are identified, including benign occipital, frontal, and psychomotor epilepsy.
- These epilepsies typically feature brief, infrequent seizures responsive to medication and self-remitting.
- Normal EEG background with sleep-activated spikes is common; Landau-Kleffner syndrome is sometimes included.
Conclusions:
- Benign partial epilepsies represent a spectrum of childhood-onset seizure disorders.
- Early identification and understanding of these syndromes are crucial for appropriate management.
- Further research into genetic and clinical aspects can refine diagnostic and therapeutic approaches.
Abstract:
Although rolandic epilepsy is the only epileptic syndrome that, at present, fully meets all the criteria of benignity and is widely recognized as such, there are also other forms of partial epilepsy that are benign. These are also genetically determined and age-dependent, occurring in neurologically intact children older than 18 months of age. As a rule, the seizures are brief and infrequent, usually responding well to antiepileptic drugs and remitting spontaneously before adulthood. The EEG background is normal, the morphology of the spikes is typical, and they are activated by sleep; generalized spike-wave discharges may occur. During the past decade, there have been reports of a number of additional syndromes of benign partial epilepsy. These include benign occipital epilepsy (the most common in this group), benign frontal epilepsy, benign epilepsy with affective symptomatology (or benign psychomotor epilepsy), benign epilepsy with extreme somatosensory evoked potentials, benign partial epilepsy of adolescence, and benign epilepsy associated with multiple spike foci. The Landau-Kleffner syndrome is often included among the benign epilepsies. These nonrolandic benign epilepsies are described in detail, and the relevant literature is reviewed.
