**Acknowledgements**

I express my deep appreciation to my supervisor Dr. Abdul Hawas Manshour for his assistance and Dr. Ahmed Shamakhi and the staff of Department of Paediatrics at the King Fahd Central Hospital, Jazan, for their support by providing me a platform to deepen my knowledge and practice of Paediatric Neurology. I am indebted too to my beautiful "Finebaby"—Mrs. Linda Chigozie Ogoke whose sweet love and support sustained me during the period of writing up of this book chapter.
