What is electrical status epilepticus in sleep?

Electrical status epilepticus in sleep (ESES) describes an electroencephalographic pattern showing significant activation of epileptiform discharges in sleep. The terms continuous spike wave in slow-wave sleep (CSWS) and Landau-Kleffner syndrome (LKS) describe the clinical epileptic syndromes seen with ESES.

What causes spikes in brain waves?

Epileptic encephalopathy with continuous spike-and-wave during sleep (CSWS): Continuous spike and wave activity is seen during sleep. This can be seen in many different seizure subtypes and epilepsy syndromes. It can be caused by structural abnormalities of the brain, genetic abnormalities, and metabolic derangements.

What is Eecsws?

Rare within rare – ESES Electrical status epilepticus during slow-wave sleep (ESES), also known as continuous spike-wave of slow sleep (CSWS) or epileptic encephalopathy with continuous spike-and-wave during sleep (or EECSWS) is a rare epilepsy syndrome which is usually seen in children who already have epilepsy or …

What is spike-wave discharges?

A spike-and-wave discharge is a regular, symmetrical, generalized EEG pattern seen particularly during absence epilepsy, also known as ‘petit mal’ epilepsy. The basic mechanisms underlying these patterns are complex and involve part of the cerebral cortex, the thalamocortical network, and intrinsic neuronal mechanisms.

What causes nocturnal seizures?

It’s believed that sleep seizures are triggered by changes in the electrical activity in your brain during certain stages of sleeping and waking. Nighttime seizures occur most often in the early morning around 5 a.m. to 6 a.m. and occur least often shortly after falling asleep.

What do Eses seizures look like?

It shows continuous spike and slow wave epileptic activity during sleep, especially during part of sleep called ‘slow wave’ sleep. This is often continuous and lasts for many minutes, even for the whole time the child is in slow sleep. This is why ESES is also called ‘continuous spike-wave of slow sleep’ (CSWSS).

What causes slow brain waves?

Several different etiologies may provoke generalized background slowing, including the effects of sedative centrally acting medications, neurodegenerative disorders, a widespread neurodevelopmental process, hydrocephalus, metabolic or toxic encephalopathy, CNS infectious disorders such as meningoencephalitis, or even a …

What does it mean to have slow brain waves?

Slow waves (≤4 Hz) can be found in seizures with impairment of consciousness and also occur in focal seizures without impairment of consciousness but with inhibited access to memory functions.

How long does the average person live with epilepsy?

Reduction in life expectancy can be up to 2 years for people with a diagnosis of idiopathic/cryptogenic epilepsy, and the reduction can be up to 10 years in people with symptomatic epilepsy. Reductions in life expectancy are highest at the time of diagnosis and diminish with time.

Does abnormal EEG confirm epilepsy?

An abnormal EEG doesn’t automatically mean that you, for example, have epilepsy. The EEGs of babies and young children can often record irregular patterns that don’t mean anything, or the irregularities may flag previously diagnosed neurological conditions such as cerebral palsy.

What is continuous spikes and waves during sleep?

Continuous spikes and waves during sleep (CSWS) is a rare epileptic encephalopathy of childhood characterized by seizures, an electroencephalographic (EEG) pattern of electrical status epilepticus in sleep (ESES) and neurocognitive regression in at least 2 domains of development.

What is epileptic encephalopathy with continuous spikes and waves during slow sleep?

Epileptic encephalopathy with continuous spikes and waves during slow sleep (EECSWSS) is an age-related childhood condition characterized by epilepsy, cognitive or behavioral impairment, and electroencephalographic abnormality of continuous spike-wave discharges during slow sleep. Continuous spikes …

Is there a treatment for continuous spike-and-wave discharges during slow sleep?

There is no specific treatment with durable effects on the seizures and neuropsychological disorders. Management of CSWSS syndrome requires teams specialized in pediatric epilepsy and neuropsychology. The continuous spike-and-wave discharges during slow sleep (CSWSS) syndrome is a rare form of infantile epilepsy.

What does slow spike wave mean ON EEG?

Almost continuous slow-spike-wave is seen during the slow sleep cycle. Your physician might use the term ESES, which stands for electrical status epilepticus during slow sleep. These EEG changes may happen in more than 85% of the child’s sleep time. The EEG changes improve during the REM sleep cycle.
