The nervous system plays an essential role in regulating body functions, coordinating movement, processing sensory input, maintaining cognition, and controlling vital responses. Disorders of this complex system such as stroke, traumatic brain injury, spinal cord injury, meningitis, epilepsy, Parkinson’s disease, dementia, multiple sclerosis, brain tumors, and neuromuscular disorders pose significant clinical challenges due to their potential impacts on function, independence, and quality of life. Therefore, comprehensive understanding of pathophysiology, clinical manifestations, diagnostic evaluations, emergency responses, rehabilitation strategies, and holistic nursing care is fundamental to ensuring safe and effective practice. Through mastery of the concepts presented in this book, it is expected that readers will strengthen their competence in providing patient-centered neurological nursing care grounded in current scientific evidence.
