Absence seizures: when the EEG is clear and the spells keep coming.

Blanking out, losing seconds, staring into space. Some of it is epilepsy, and some of it is not, and the difference matters enormously.

This page is about understanding the condition and the role the brain and nervous system can play in it. It is not a diagnosis. Your own clinicians know your case.

Getting the seizure diagnosis right

Absence seizures are epilepsy, and the first job is to diagnose them properly. In a typical absence seizure a child stops mid-sentence or mid-activity, stares blankly, may blink or make small lip or hand movements, does not respond to touch or voice, and after 5 to 15 seconds carries on with no memory of the gap. They can happen dozens of times a day and are often first noticed by teachers. Childhood absence epilepsy usually starts between ages 4 and 10 and often remits in adolescence.

Diagnosis rests on the story and on an EEG, which in absence epilepsy shows a very recognizable three-per-second spike-and-wave pattern, often provoked by hyperventilation in the clinic. Medications such as ethosuximide and valproate control the seizures in most children. Untreated absence seizures affect learning and safety, so this is not a diagnosis to delay.

Any new staring spells, episodes of unresponsiveness, or any event with falling, shaking or injury need medical evaluation. Never stop anti-seizure medication without the prescribing doctor.

The neuroplastic contribution

The ATNS Index of Neuroplastic Symptoms states that absence seizures are not due to neuroplastic symptoms. It then adds the important qualifier: if the episodes are atypical, or the response to treatment is not what was expected, neuroplastic symptoms should be evaluated as a potential cause.

Neuroplastic symptoms are real, physical symptoms produced by learned pathways in the brain and nervous system rather than by disease, in this case rather than by abnormal electrical discharges. The brain can produce episodes of blanking out, staring, unresponsiveness and lost time without any seizure activity. In children and adults these are often called psychogenic non-epileptic seizures, dissociative seizures or, when they look like absences, 'pseudo-absences'. They are not faked and not under conscious control. They are a learned response of a nervous system under strain, often triggered by stress, and they are part of the wider family of functional neurological disorder.

The distinction matters because the treatments are different. Anti-seizure medication does not stop non-epileptic episodes, and years can be lost increasing doses for spells that were never electrical. Meanwhile the approach that does help, which addresses the nervous system's learned pattern, goes untried. The index's advice is a way of making sure that does not happen. See our page on psychogenic non-epileptic seizures for the fuller picture.

What the research shows

The research here concerns distinguishing epileptic absences from non-epileptic staring, and it is consistent: many staring spells are not seizures, and careful history plus video-EEG is the way to tell.

• A video-EEG study of the differential diagnosis of staring spells in children found that a careful history separated epileptic from non-epileptic staring in most cases, and that video-EEG monitoring resolved the remaining difficult ones. Non-epileptic staring was common.
• A practical guide to treating childhood absence epilepsy lists features that distinguish true absences: abrupt loss of facial expression, automatic movements such as lip smacking, onset during active tasks like chewing or play, no response to touch, and the fact that teachers tend to notice them before parents. Behavioral staring, by contrast, tends to occur during passive activities like watching television and stops when the child is touched or called.
• A review of psychogenic non-epileptic seizures in children noted that they are common but frequently missed, that home video helps with motor events, and that absence-like episodes are the hardest to classify without video-EEG. Treatments aimed at the underlying stress and learned response, rather than at epilepsy, are the standard of care once the diagnosis is made.

These studies do not describe a neuroplastic approach by that name. They establish that atypical or treatment-resistant staring episodes frequently turn out to be non-epileptic, which is exactly the situation in which the index asks for neuroplastic symptoms to be considered.

Signs the brain may be part of the picture

• EEG, including with hyperventilation and ideally prolonged video monitoring, has not captured the typical spike-and-wave pattern during an episode.
• Episodes last longer than 20 to 30 seconds, or vary widely in length.
• The person can be brought out of the spell by touch, a loud voice or a question.
• Episodes happen mainly during passive moments, in stressful settings, or in front of particular people, and never during absorbing activity.
• Anti-seizure medication at adequate doses has not reduced the episodes, or they have increased.
• Episodes began after a stressful event, bullying, loss, illness or family upheaval.
• There are other functional or sensitized-system symptoms: headaches, stomach aches, dizziness, fatigue, sleep problems.

A solution that addresses it

For episodes that turn out to be neuroplastic rather than epileptic, there is an approach designed for them. Symptom reprocessing combines education about how the brain produces these episodes, somatic tracking (noticing the early warning sensations with curiosity rather than fear), reducing threat and shame around the spells, graded return to school, work and activity, emotional awareness and expression, and acceptance and commitment skills. It is delivered by trained clinicians, often in neurology and psychology teams, and increasingly through digital programs. It is used alongside, and never in place of, a neurologist's care. Our introduction to ACT explains the acceptance piece.

Cindra is a daily AI companion built around these approaches, with daily check-ins, short practices and plain-language lessons, for people whose symptoms have a neuroplastic component. For adults and older teens with a confirmed non-epileptic component, you can join the waitlist.

What to do next

See a neurologist and get an EEG, with video monitoring if the first EEG is unclear. Episodes with falling, injury, incontinence, confusion lasting minutes, or any event in water or at height need urgent attention. Keep all anti-seizure medication exactly as prescribed until a neurologist advises otherwise.

If the EEG does not support epilepsy, or treatment is not working, ask the neurologist directly whether the episodes could be non-epileptic or neuroplastic. A clear answer is a relief, not a dismissal: these episodes are real and they respond to the right approach. Then begin learning, with the whole family if the person affected is a child, and start the work of calming the nervous system that produces them.

This article is for general education and is not medical advice, and it does not diagnose or treat any condition. Persistent symptoms deserve a proper medical assessment to rule out disease or injury before a neuroplastic explanation is considered. If your symptoms are new, changing, or come with red-flag signs such as fever, unexplained weight loss, numbness or weakness, chest pain, or loss of bladder or bowel control, see a clinician promptly.
