Book excerpt: Reading EEGs: A Practical Approach focuses on pattern recognition and pattern comparison. The concepts of pattern recognition are developed in a logical fashion based on appearance rather than disease process. The book teaches waveform recognition so that the reader can generate a differential diagnosis based on that recognition. This book also incorporates a question-and-answer format that is effective for students at multiple levels of training. A unique feature of the book is that it follows a teaching methodology in which concepts are developed sequentially and logically.
