The Paroxysmal Disorders

dedicated section), or drop attacks. In addition, despite the ‘updating’ intents, the texts appear at least in part relatively dated. For instance, there is no mention throughout the book about the link between paroxysmal exercise-induced dystonia, glucose transporter (GLUT1) deficiency, and epilepsy (which is known at least since 2008), and the therapeutic role of ketogenic diet. The section on epilepsy treatment does not mention medications marketed since 2006, but reports compounds that are nearly almost forgotten (as tiagabine). Furthermore, one would have expected more emphasis on conditions such as vestibular neuritis, epileptic amnesia, semiology of visual illusions/hallucinations (e.g. the role of color in the differential diagnosis between epileptic and migraine auras, or the superposition on the background for peduncular hallucinosis) and of paresis (e.g. no detailed description of the Hoover sign is found), or epilepsy-induced syncope, which may at times challenge the emergency physician/neurologist. Despite these drawbacks, several book parts are very well written and useful for the clinician, like the headache, the ENT (vertigo), sections of the ophtalmological, and the PNES chapters, while other encompass some details (e.g. epilepsy treatment, stroke diagnosis and treatment) that may go beyond the intent of the editors of this work. In conclusion, despite finding much interesting information, the reader may welcome a truly updated edition of this book, where a general diagnostic overview of paroxysmal conditions (e.g. as a table or flow chart) could also contribute to a more homogeneous and synthetic result, and to an additional usefulness for the clinician.
