Epilepsy and EEG - Coggle Diagram

- - - - Normal frequency and amplitudes are age dependent, rhythms seen in awake EEG
    - - Normal sleep features, Vertex waves, K complexes Sleep spindles
    - - Diffuse or generalized background slowing
      - Focal Slowing: Underlying area of abnormal function
    - - Generalized spike and Wave
      - Focal Spike and Wave
    - - Hyperventilation: Symmetric high amplitude slowing
      - Photic Stimulation: Driving response
    - - Generalized: Waves appearing on all portions of the EEG
      - Focal: Waves appearing only on certain lines of the EEG
  - - - Always refereed for consideraiton of surgery or alternate treatments (2 trials of tolerated, appropriately chosen and used anti-seizure medication)
      - Localization to see if seizures localize to a single place
