EEG Evaluation for 9-Year-Old Female Patient

EEG slides of a 9-year-old female patient in an awake state with eyes closed and no medication reveal various segments in monopolar and bipolar montages. The EEG changes are compared between different montages, including segments with notable alterations. Changes in brain activity are observed during different states and eye movements, providing valuable insights for clinical assessment.

Presentation Transcript

1. Case 1, female EEG (9 yrs 9 mths) Please look at the slides without more clinical information Remember what prof. S. Beniczky told you last week, read EEGs blind Age and state of the patient is important: Almost 10 years, awake, no medication

2. Case 1, segment 1, awake, eyes closed, monopolar and bipolar montage of the same EEG segment

3. Case 1, segment 2 in bipolar montage, eyes closed (EC); in the upper part you can see where in the EEG the slide is taken

4. Case 1, segment 3, monopolar montage

5. Case 1, segment 4, segment just after the previous slide

6. Case 1, segment 4b, same as on previous slide, now bipolar montage, eyes closed

7. Next page, segment 4c in monopolar montage; ComAvg + Low Row

8. Segment 4c now in bipolar montage, eyes closed

9. Eyes opening Same segment in bipolar and monopolar montage for comparison

10. 5a - segment with EEG change

11. 5a - segment with EEG change

12. 5a - segment with EEG change - bipolar montage

13. Segment with EEG change beginning and middle part

14. The end (monopolar and bipolar montage of the same segment)

15. A lower paper speed The whole discharge

16. Patient 1, discharge during hyperventilation (1)

17. Patient 1, discharge during hyperventilation (1)

18. Patient 1, discharge during hyperventilation (1), 500 V/cm; bipolar montage

19. Patient 1, discharge during hyperventilation (2nd episode), 500 V/cm; bipolar montage

20. Patient 1, spontaneous discharge, 500 V/cm; bipolar montage

21. Last discharge, spontaneous

22. What is your diagnosis just from the data you have so far? Diferential diagnosis?

23. Case 2, female 15 years

24. 15 years, female, eyes closed

25. Case 2, 15 y, eyes closed

27. Eyes closed

28. Eyes closed, monopolar and bipolar montage

29. Intermittent photic stimulation; flash frequency 8 Hz, monopolar montage (ComAvg with LowRow)

30. Intermittent photic stimulation; flash frequency 8 Hz, bipolar montage + LowRow (same as on the previous slide)

31. Intermittent photic stimulation; flash frequency 8 Hz, monopolar montage (ComAvg with LowRow) Lower paper speed , black bar = eyes closure

32. Intermittent photic stimulation; flash frequency 18 Hz, monopolar montage (ComAvg)

33. Intermittent photic stimulation; flash frequency 20Hz, monopolar montage (ComAvg)

34. Same in bipolar, IFS 20 Hy

35. What are your suggestions for the diagnosis? Do you need more data?

36. EXTRA patient 2, IFS 1 Hz what do you think about this?
