Self-limited epilepsy with centrotemporal spikes (SeLECTS) is a common childhood focal epilepsy syndrome characterised by brief focal seizures involving the face and mouth, often during sleep, together with characteristic centrotemporal epileptiform discharges on EEG.
The syndrome was historically called benign epilepsy with centrotemporal spikes or benign rolandic epilepsy. The modern name avoids implying that every affected child has no cognitive, language or educational difficulties.
Why the name changed
The word “benign” suggested that the condition was always harmless because seizures usually remit with age. Research has shown that some children experience temporary or persistent language, attention, learning or executive-function difficulties.
The ILAE therefore uses the term self-limited to describe the natural tendency of the epilepsy itself to remit, without claiming that every aspect of the condition is trivial.
Typical age at onset
SeLECTS begins in childhood, most often in the school years. Onset outside the expected childhood range should prompt review for another focal epilepsy syndrome.
Typical seizures
Seizures often begin with unilateral numbness, tingling or twitching of the tongue, lips, cheek or face.
Speech may become difficult or impossible while awareness is preserved. Drooling and guttural or throat sounds can occur.
Sleep-related pattern
Many seizures occur during sleep or around waking. Some spread to both sides of the brain and become bilateral tonic-clonic seizures.
Despite the alarming appearance of a bilateral convulsion, the underlying syndrome can still be SeLECTS when the age, focal onset and EEG are typical.
Awareness
Awareness is often preserved during the initial focal sensorimotor symptoms, although it can become impaired if the seizure spreads.
Children may remember being unable to speak despite understanding what was happening.
The EEG pattern
EEG shows characteristic high-amplitude centrotemporal spikes, often with a horizontal dipole. The discharges are strongly activated by drowsiness and sleep.
A sleep EEG can therefore be more informative than a short awake recording.
EEG spikes do not equal seizures
Centrotemporal spikes can occur without a clinical seizure and can occasionally be found in children who never develop epilepsy.
The diagnosis therefore requires the appropriate clinical syndrome rather than an EEG label alone.
MRI
Brain MRI is usually normal and is not required in a classic presentation with typical development, examination and EEG.
MRI becomes more important when seizures, neurological examination or EEG contain persistent atypical focal features.
Development and learning
Most children have broadly normal development, but subtle language, reading, attention or executive-function difficulties are reported more often than in unaffected peers.
Difficulties can fluctuate with sleep-activated epileptiform activity and may not be obvious from routine neurological examination.
When abundant sleep spikes need extra attention
Marked increase in epileptiform activity during sleep together with clear language, cognitive or behavioural regression can suggest evolution toward another epilepsy-encephalopathy spectrum rather than uncomplicated SeLECTS.
This should prompt specialist reassessment and sleep EEG.
Do all children need antiseizure medication?
No. Because seizures are often infrequent and the syndrome usually remits, treatment decisions are individual.
Medication may be considered when seizures are frequent, prolonged, disruptive, occurring during the day, associated with injury risk or causing significant family concern.
Medication choice
There is no single universally preferred medicine. Selection depends on local guidelines, seizure burden and the child’s individual profile.
The decision to treat should consider potential medicine adverse effects as well as seizure risk.
Prognosis
The epilepsy is self-limited: seizures usually stop by adolescence.
This favourable seizure prognosis should be separated from questions about language, learning or behavioural effects, which may require support even while seizures are infrequent.
Genetics
SeLECTS has a complex genetic background rather than one single causative gene in most children.
Routine genetic testing is usually unnecessary in a classic presentation, but may be appropriate if developmental impairment, atypical seizures or another neurological disorder is suspected.
Worldwide diagnosis
Where MRI and genomic testing are limited, classic SeLECTS can often still be diagnosed from history, examination and EEG.
However, access to sleep EEG is uneven worldwide, and a short awake EEG may miss or underestimate the characteristic abnormalities.
The central point
SeLECTS is self-limited, but “self-limited” does not mean every child is unaffected outside seizures. The syndrome usually remits by adolescence, yet language, learning and attention deserve assessment when concerns arise.

Medical note: whether to start antiseizure medication in SeLECTS is an individual decision based on seizure frequency, timing, safety and the child’s wider needs.
