Presentation
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]

Seizure
EEG of a 16-yr-old child with MR and tonic seizures, showing slow spike wave activity superimposed on a slow BG. 22. EEG of an 11-yr-old pt with LGS showing GPFA. 23. Tonic seizure in a patient with LGS. 24. [slideshare.net]
[…] tonic-clonic seizures, atypical absence, atonic, and other type of seizures. [j-epilepsy.org]
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]
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]

Focal Epileptiform Discharges

Prognosis
Hence, early diagnosis, effective treatment and termination of continuous spike and slow-wave discharge can ameliorate the prognosis of children [3]. [jitm.hk]
