This document discusses different types of brain waves seen on EEGs, including alpha, beta, theta, and delta waves. It then summarizes several common epilepsy syndromes such as benign centrotemporal lobe epilepsy of childhood, juvenile myoclonic epilepsy, autosomal dominant nocturnal frontal lobe epilepsy, Lennox-Gastaut syndrome, childhood absence epilepsy, and others. It provides examples of EEG findings associated with these conditions, such as Rolandic spikes, generalized spike and wave discharges, and hypsarrhythmic patterns.

1. Recognizing epilepsies Dr. Francois Kouya

5. Eyes Closed, 14 yrs. old. Very clear beta spindles Frontocentral

6. Eyes Open, 43 yrs. old: Clear frontocentral beta spindles, high-frequency (31-36 Hz).

9. Normal EEG

11. Partial or focal EP Benign rolandic epilepsy (BRE)

12. Rolandic spikes and Epilepsy with Continuous spike and waves during slow wave sleep (ECSWS)

14. Polyspike and wave discharges seen in juvenile myoclonic epilepsy

17. Frontal lobe EP

18. Autosomal dominant nocturnal frontal lobe epilepsy

21. EEG of a 53-year-old man with one day history of acute confusion and slowness of motor responses, showing almost continuous generalized spike wave activity.(status epilepticus)

22. Partial or focal EP Benign Rolandic epilepsy (BRE)

23. EEG of an 11-year-old patient, showing rhythmic midtemporal discharges during drowsiness

24. EEG of a 26-year-old patient, showing 6 Hz spike wave paroxysms (phantom spike wave).

25. EEG of a 9-year-old child with benign Rolandic epilepsy, showing a focus of right centrotemporal spike discharges. The right half of the figure shows a spike discharge with horizontal dipole distribution.

26. EEG of a 68-year-old patient with a long history of complex partial seizures, showing a focus of sharp waves and low-amplitude slow activity over the right anterior temporal region

28. EEG of an 11-year-old patient with Lennox-Gastaut syndrome, showing generalized paroxysmal fast activity (B)

29. EEG of a 16-year-old child with mental retardation and tonic seizures, showing slow spike wave activity superimposed on a slow background .

30. Epilepsies in babies

31. EEG of a 3-day-old comatose neonate with history of seizures, showing an electrographic "alpha band" seizure pattern without clinical accompaniment

32. EEG of a 5-day-old neonate, showing focal ictal pattern characterized by rhythmic sharp waves in the left Rolandic region

33. EEG of a 5-day-old neonate on ventilator, showing "depressed brain seizure" characterized by less than one per second, low-amplitude sharp waves over the right hemisphere.

34. EEG of a 6-month-old infant with developmental delay and infantile spasms, showing typical hypsarrhythmic pattern

37. Typical 3-Hz spike and wave discharges seen in absence epilepsy

38. EEG in Creutzfeldt-Jakob disease

40. EEG in Alzheimer's patients
