後で発作を確認してください。
彼は、これらが正常性の変形であることを否定しています。
ムーリズムとラムダ波。
Hypnagogic hypersynchrony.
ウィケットスパイク。
その他:

正規性のバリアントのパターンを学習するためのリソースは複数あります。

てんかんに関係のない病理学的所見の存在を考慮に入れてください。
ギャップのリズム。
過剰なベータ活性(ベンゾジアゼピン含浸)。
根底にある神経発達障害。

てんかんのない成人におけるてんかん様活動の発生率は 2 ~ 3%、てんかんのない小児では 5%、てんかんのない神経発達障害のある小児では 40 ~ 50% です。

その他:

病理学的パターンを学習するためのリソースは複数あります。

てんかん放電が 2 つの特徴を満たしていることを確認してください。
  • これは一致する磁場を持ちます。先端の逆位相のパターン (脱分極) を分析することによって、その原点を特定することができます。
  • これは基本リズムをオーバーライドするため、その後に遅い波 (再分極) が現れると識別しやすくなります。
最後に、基本パターンと発作に応じて、パターンを次の 5 つのグループのいずれかに分類することにより、てんかん症候群を分類します。
