Childhood Epilepsy
• Seizure in childhood is common and indicates
cerebral diseases and damage developing brain
• Incidence Febrile 2%, idiopathic 1%
• Clinical feature limited to motor phenomena
• EEG signs are are often variable and nonspecific
and their interpretation difficult

minimum dose

![Page 51: Management of epilepsy in children](https://reader035.vdocuments.net/reader035/viewer/2022062313/5589d886d8b42a4d6f8b46eb/html5/thumbnails/51.jpg)
What is the chance of remission?
• 50% Remission off treatment for 20
years
• 20% Remission on treatment

![Page 52: Management of epilepsy in children](https://reader035.vdocuments.net/reader035/viewer/2022062313/5589d886d8b42a4d6f8b46eb/html5/thumbnails/52.jpg)
Good prognostic signs• Granuloma• Early posttraumatic epilepsy• Mild infrequent seizure• Secondary systemic or toxic
seizure• Benign rolandic epilepsy• Primary generalized epilepsy• Absence seizure• Early treatment
![Page 53: Management of epilepsy in children](https://reader035.vdocuments.net/reader035/viewer/2022062313/5589d886d8b42a4d6f8b46eb/html5/thumbnails/53.jpg)
Bad prognostic signs
• Diffuse cerebral disease
• Late posttraumatic epilepsy
• Multiple seizure types
• Complex partial seizure
• Long untreated seizure

![Page 54: Management of epilepsy in children](https://reader035.vdocuments.net/reader035/viewer/2022062313/5589d886d8b42a4d6f8b46eb/html5/thumbnails/54.jpg)
When to stop treatment
• Primary generalized seizure with normal
EEG for 2-3 seizure free years
• Taper slowly
• Severe brain damaged needs life long
treatment
• Short course following medical disorder
![Page 55: Management of epilepsy in children](https://reader035.vdocuments.net/reader035/viewer/2022062313/5589d886d8b42a4d6f8b46eb/html5/thumbnails/55.jpg)
Intractable seizures
• 20-30% of epilepsy
• Poor compliance
• Inadequate drug doses
• Improper choice of drug
• Inappropriate combination of drugs
• Misdiagnosis of seizure or seizure type
![Page 56: Management of epilepsy in children](https://reader035.vdocuments.net/reader035/viewer/2022062313/5589d886d8b42a4d6f8b46eb/html5/thumbnails/56.jpg)
