Presentation
We concluded that CSWS is a non specific electrographic pattern observed in some types of epilepsy in childhood that have different clinical presentation. [scielo.br]
Rolandic spikes are also present in children with other generalized epileptiform activity. Abstracts of BRE articles present more details on EEG features and variations for BRE. [pediatrics.emory.edu]

The survey presented a clinical vignette of CSWS. The questions addressed treatment choices for that clinical scenario. Surveys were self-administered and collected using an online survey website (www.surveymonkey.com). [scholars.northwestern.edu]
Entire Body System
- Inflammation
MRI of the left shoulder and brachial plexus showed no plexus inflammation and no joint abnormalities. [jcsm.aasm.org]
Abnormal Results Abnormal results on an EEG test may be due to: • An abnormal structure in the brain (such as a brain tumor) • Attention problems • Tissue death due to a blockage in blood flow (cerebral infarction) • Drug or alcohol abuse • Head injury • Inflammation [biomedresearches.com]
- Unconsciousness
There are many different types of generalised seizures but they all involve the person becoming unconscious, even just for a few seconds, and they won't remember the seizure itself. [epilepsysociety.org.uk]
Neurologic
- Seizure
According to Lerman, the seizure frequency is low, 13% may have just one seizure, 66% have infrequent seizures, and 21% have frequent seizures. [euroformhealthcare.biz]
Focal seizures can progress to affect both sides of the brain. When this happens, the seizure is called a bilateral seizure, usually tonic-clonic seizures or convulsions. Other seizure types include absence, atypical absence, and atonic seizures. [epilepsy.com]
There are other medical conditions that might cause someone to have a seizure for example, diabetes. The difference between epileptic seizures and other seizures is that epileptic seizures are caused by a disruption in the way the brain is working. [epilepsysociety.org.uk]
Results Clinical characteristics Epileptic seizures occurring in all children mainly included generalized clonic seizure, tonic clonic seizure, myoclonic absence seizure, absence seizure and unilateral limb clonus or mouth and facial seizure. [jitm.hk]

However, these have typically had little to no effect on the long-term development of aphasia. [docneuro.com]
Although the term epileptic aphasia has been used for LKS, epileptic aphasia by its strict definition refers to an aphasia caused by an actual seizure or, in other words, an ictal aphasia. [emedicine.medscape.com]
- Focal Seizure
Clinical manifestations Three stages of evolution: First stage before CSWS: infrequent nocturnal motor focal seizures, often hemiclonic status epilepticus, absences, atonic, complex focal seizures, and generalized tonic-clonic seizures occur. [epilepsy.com]
Inclusion criteria were: (1) focal seizures or apparently generalized seizures and focal EEG epileptiform discharges; (2) further occurrence of atypical absences, and myoclonic, atonic, and/or generalized seizures; (3) cognitive impairment and/or behavior [moh-it.pure.elsevier.com]

- Hyperactivity
Hyperactivity and oppositional behaviors are highly associated. [intechopen.com]
There is marked decrease in intelligence quotient scores with attention deficit and hyperactivity, sometimes with language disturbances and autistic features. [neuroscienceandgenetics.it]
Almost half of the patients exhibited other cognitive deficits, such as attention deficit, language disturbances, hyperactivity and behavior problems. [pediatricneurosciences.com]
There is often a history of loss of language and temporo-spatial skills, hyperactivity, short-term memory deficits and behavioural problems. [acnr.co.uk]
- Atonic Seizures
In atypical benign focal epilepsy of childhood (ABFEC) several types of seizure, especially partial motor fits, atypical absences and myo-atonic seizures occur. [moh-it.pure.elsevier.com]
Focal seizures can progress to affect both sides of the brain. When this happens, the seizure is called a bilateral seizure, usually tonic-clonic seizures or convulsions. Other seizure types include absence, atypical absence, and atonic seizures. [epilepsy.com]
Some of these beta bursts may be associated with tonic seizures. initial seizures similar to BRE, but then evolving into periodic atonic seizures, with brief absences and GTCS. Atonic episodes correlate with the slow wave discharges on EEG. [euroformhealthcare.biz]

Treatment

Treatment of CSWS There are no controlled trials for the treatment of CSWS, only large cohort studies. [acnr.co.uk]
But because the child responded well to medical treatment, a wait-and-see approach was justified. [consultqd.clevelandclinic.org]
Valproate, lamotrigine, levetiracetam and sulthiame# may be the most appropriate treatments. The treatment of CSWS, which is responsible for the neuropsychological impairment, is entirely empirical and usually of transient efficacy. [epilepsy.com]
Prognosis
Hence, early diagnosis, effective treatment and termination of continuous spike and slow-wave discharge can ameliorate the prognosis of children [3]. [jitm.hk]
Management options* Seizures are not a major problem as their final prognosis is good. Valproate, lamotrigine, levetiracetam and sulthiame# may be the most appropriate treatments. [epilepsy.com]
Prognosis The prognosis is related to the underlying disorder. The severity of developmental impairment varies with the type of epilepsy. Early infantile epileptic encephalopathy (Ohtahara syndrome) The prognosis is very poor. [emedicine.medscape.com]
The prognosis is worse if the spasms are either symptomatic or cryptogenic. [euroformhealthcare.biz]

Etiology
Rett syndrome Metabolic etiologies (e.g. mitochondrial disorders) [epilepsydiagnosis.org]
The developmental prognosis partially depends on the etiology. When classified by etiology, normal development was described in 51% of cryptogenic cases versus only 6% of symptomatic cases. [emedicine.medscape.com]
Significance: ESES/CSWSS syndrome is an epileptic encephalopathy with similar electroclinical findings in children with a >85% spike-wave index and those with a AB - Purpose: To retrospectively analyze the electroclinical features, etiology, treatment [moh-it.pure.elsevier.com]
Etiology Symptomatic, probably symptomatic and idiopathic. [epilepsy.com]

Prevention
Sleep EEGs should be performed for timely diagnosis, proper treatment and prevention of permanent cognitive impairment. [pediatricneurosciences.com]
These changes are due to continuous spikes in the frontal region of the brain during sleep that prevent further neurodevelopment. Clinical onset peaks around four to seven years of age. [articles.complexchild.com]
Treatment with clonazepam is effective in preventing most REM parasomnias. Autism and Sleep Sleep-wake problems occur in 40 to 80% of children with autism. [childneurologyfoundation.org]
