This eBook is the premier volume of our "Mental Illness/Central Nervous System" series, focussing specifically on "ELIMINATION DISORDERS (ENURESIS AND ENCOPRESIS)". This eBook release encompasses diagnoses such as enuresis, encopresis, and others. The content comprises a total of 85 "MCQs with Guiding Answers" and 297 "Linked References". This eBook also contains numerous "Study Highlights or Summary Keypoints" alongside the "CLINICAL PRACTICE INSIGHTS" section. Our primary clients include medical professionals, clinical pharmacists or PharmDs, nurses, and various other individuals in the healthcare sector, such as mentors, residents, and students. We adhere to conventional design principles for all our sequential eBook publications to circumvent the trend of "hypercoloremia mania" in eBook design. This predominantly employs the official black and white colour scheme. This publication resulted from a collaborative effort with my skilled and dedicated coauthors, namely PharmDs Farah Qaryouti, Marah Hussein, Alia' Saidan, Kariman Hatem, Leen Albishawi, Arwa Alashqar, Eman Awwad, Areej Al-Manasyeh, Dana AlTaweel, Duaa Alqhaiwi, and Najd Alyasjeen.
