Electrical Status Epilepticus in Sleep (ESES) is a rare, self-limiting form of non-convulsive status epilepticus that typically affects children between the ages of 2 and 12, with a peak incidence between 3 and 5 years. It is characterised by a specific pattern of continuous epileptic discharges during non-rapid eye movement (NREM) sleep, resulting in an electroencephalography (EEG) pattern of near-continuous spike-wave discharges. The pathogenesis of ESES is not fully understood, but it is thought to be related to disruptions in normal electrical activity and neural networks within the brain, especially during the slow-wave sleep phase. Treatment for ESES aims to suppress EEG abnormalities and improve seizure control with anti-seizure medications, high-dose benzodiazepines, and corticosteroids.

ESES is a rare, self-limiting form of non-convulsive status epilepticus
Electrical Status Epilepticus in Slow-wave Sleep (ESES) is a rare form of non-convulsive status epilepticus. It is characterised by a specific pattern of continuous epileptic discharges during non-rapid eye movement (NREM) sleep. ESES is an epilepsy syndrome with sleep-induced epileptic discharges and an acquired impairment of cognition or behaviour. It is an age-dependent condition that typically affects children between the ages of 2 and 12, with a peak incidence between 3 and 5 years.
ESES is a self-limiting condition, meaning that it resolves on its own without treatment. However, it can be difficult to treat with medication if needed, as it is often resistant to traditional anti-seizure medications. Treatment for ESES aims to suppress EEG abnormalities and improve seizure control with antiseizure medications, high-dose benzodiazepines, and corticosteroids. The condition usually resolves after puberty, but children may experience impaired thinking and learning abilities.
The pathogenesis of ESES is not fully understood, but it is thought to be related to disruptions in the normal electrical activity and neural networks within the brain, especially during the slow-wave sleep phase. Various etiologies have been suggested, including structural abnormalities of the brain, concurrent genetic mutations, and an imbalance between counterregulatory neurotransmitters, resulting in disruptions in information processing and memory consolidation. Diagnosis is confirmed with an EEG showing continuous or near-continuous spike-wave discharges during NREM sleep and intermittent focal and/or multifocal epileptiform discharges during REM sleep.
ESES is often associated with Landau-Kleffner Syndrome (LKS), a rare epilepsy syndrome characterised by the sudden or gradual development of aphasia and recurrent epileptic seizures. The International League Against Epilepsy has adopted the term “continuous waves and spikes during sleep” (CSWS) to describe the clinical phenotype of ESES, which includes global developmental regression.

It is characterised by a specific EEG pattern during non-rapid eye movement sleep
Electrical Status Epilepticus in Sleep (ESES) is a rare, self-limiting form of non-convulsive status epilepticus. It is characterised by a specific electroencephalogram (EEG) pattern during non-rapid eye movement (NREM) sleep. This pattern is marked by nearly continuous spike-wave discharges during NREM sleep and intermittent focal and/or multifocal epileptiform discharges during REM sleep. The condition typically affects children between the ages of 2 and 12, with a peak incidence between 3 and 5 years.
The pathogenesis of ESES is not yet fully understood, but it is thought to be related to disruptions in the normal electrical activity and neural networks within the brain, particularly during the slow-wave sleep phase. Studies have identified various etiologies, including structural abnormalities of the brain, concurrent genetic variants, and an imbalance between excitatory and inhibitory neurotransmitters.
The diagnosis of ESES is confirmed through EEG readings, which show the characteristic pattern of continuous epileptic discharges during NREM sleep. Treatment for ESES aims to suppress these EEG abnormalities and improve seizure control. However, it can be challenging due to the resistance to traditional anti-seizure medications. Treatment options include numerous antiepileptic drugs, immunomodulatory agents, and in some cases, surgical interventions.
The International League Against Epilepsy has adopted the term ""continuous waves and spikes during sleep" (CSWS) to describe the clinical phenotype of ESES, which includes global development regression and the distinctive EEG pattern. ESES is a severe form of epilepsy that can cause cognitive difficulties, and it typically resolves after puberty.

ESES is a childhood-onset epileptic syndrome, typically affecting children between 2 and 12 years old
Electrical Status Epilepticus in Slow Sleep (ESES) is a rare, severe form of epilepsy that typically affects children between the ages of 2 and 12, with a peak incidence between 3 and 5 years. It is a self-limiting form of non-convulsive status epilepticus, characterised by a specific electroencephalogram (EEG) pattern during non-rapid eye movement (NREM) sleep. This pattern consists of continuous or near-continuous spike-wave discharges, indicating epileptiform activity.
ESES is often associated with cognitive regression and behavioural disturbances, including Landau-Kleffner Syndrome (LKS), which causes aphasia and recurrent epileptic seizures. The pathogenesis of ESES is not fully understood, but it is believed to be related to disruptions in normal electrical activity and neural networks within the brain, particularly during slow-wave sleep. These disruptions may be caused by structural abnormalities in the brain, genetic mutations, or an imbalance in neurotransmitters, resulting in issues with information processing and memory consolidation.
The diagnosis of ESES is confirmed through EEG readings, which show the distinctive spike-wave activity during NREM sleep. MRI scans are also used to look for any structural changes in the brain, although these may not always be present. Genetic testing may also be conducted to identify any underlying genetic variants.
Treating ESES can be challenging due to its resistance to traditional anti-seizure medications. Treatment options include antiseizure medications, high-dose benzodiazepines, corticosteroids, immunomodulatory agents, and, in rare cases, surgery. The goal of treatment is to suppress EEG abnormalities and improve seizure control.
ESES typically resolves after puberty, but children may experience long-term cognitive difficulties, including impaired thinking and learning abilities.

Treatment involves suppressing EEG abnormalities and improving seizure control with anti-seizure medications
Electrical Status Epilepticus in Sleep (ESES) is a childhood-onset epileptic syndrome with sleep-induced epileptic discharges and cognitive and behavioural disturbances. Treatment for ESES can be challenging and varied, and there is little evidence to guide treatment due to a lack of large-scale studies. However, the main goal of treatment is to suppress EEG abnormalities and improve seizure control.
EEG abnormalities can be suppressed through the use of anti-seizure medications (ASMs) such as benzodiazepines and corticosteroids, which are the mainstay of recommended treatment. These medications work by controlling abnormal electrical activity in the brain. While most patients with acute epileptiform EEG findings do not require long-term ASMs, those with persistent abnormalities on follow-up EEGs have a higher chance of developing epilepsy. Therefore, ASMs can play a crucial role in preventing the progression to epilepsy.
In addition to benzodiazepines and corticosteroids, other antiepileptic drugs and immunomodulatory agents may be used to manage seizures in ESES. Diazepam (Valium) is another option that can be given orally, as an injection, IV, or rectal suppository, although tolerance can develop over time. Other anti-seizure medications such as VIMPAT can be used alone or in combination with other drugs to treat partial-onset seizures.
The type of anti-seizure medication prescribed will depend on various factors, including side effects, other illnesses, and the delivery method. It is important to monitor treatment progress and adjust plans as necessary to optimize patient outcomes. A mental health nurse should be involved in the care of patients with ESES due to the presence of neuropsychiatric features. Additionally, a pharmacist should educate patients and caregivers about the drugs' adverse effects, benefits, and potential drug interactions.

The pathogenesis of ESES is not fully understood but is thought to be related to disruptions in normal electrical activity and neural networks within the brain
Electrical Status Epilepticus in Sleep (ESES) is a rare, self-limiting form of non-convulsive status epilepticus. It is characterised by a specific pattern of continuous epileptic discharges during non-rapid eye movement (NREM) sleep. ESES is typically found in children between the ages of 2 and 12, with a peak incidence between 3 and 5 years.
The pathogenesis of ESES is not fully understood, but it is thought to be related to disruptions in normal electrical activity and neural networks within the brain, especially during the slow-wave sleep phase. Studies have identified various etiologies, including structural abnormalities of the brain, concurrent genetic mutations, and an imbalance between excitatory (glutamate) and inhibitory (GABA) neurotransmitters, resulting in disruptions in information processing and memory consolidation.
Functional imaging studies have shown that patients with ESES are characterised by a consistent specific neuronal network of propagation, independent of etiology and individual areas of initial epileptic activity. The activation in the perisylvian/prefrontal network was associated with both activation in the thalamocortical network and deactivation in the default mode network. These networks' activation may influence epileptic spikes, potentially explaining neuropsychological deficits and developmental abnormalities in ESES.
The negative effects of ESES may be related to the lack or reduction of physiological sleep features during the critical period of brain maturation. Disruption of normal sleep architecture could impair the remodelling of neuronal networks that support cognitive performance, typically occurring during sleep. Longer durations of ESES, abnormal development before the onset, and the severity of initial regression are key risk factors for long-term cognitive impairment.
Diagnosis of ESES is confirmed with an electroencephalogram (EEG) showing continuous or near-continuous spike-wave discharges during NREM sleep and intermittent focal and/or multifocal epileptiform discharges during rapid eye movement (REM) sleep. Treatment is aimed at suppressing EEG abnormalities and improving seizure control with antiseizure medications, high-dose benzodiazepines, and corticosteroids.
