Chapter 35: Neurological and Cognitive Disorders

Traumatic brain injury and elevated intracranial pressure receive detailed attention, including recognition of early warning signs, late deterioration indicators, emergency management protocols, and proper positioning techniques to minimize secondary brain damage. Hydrocephalus management focuses on ventricular peritoneal shunt placement, preoperative and postoperative nursing care, recognition of shunt malfunction, and ongoing monitoring for infection or obstruction. The chapter addresses both bacterial and viral meningitis, emphasizing diagnostic procedures such as cerebrospinal fluid analysis via lumbar puncture, transmission precautions, and vigilant observation for serious complications including seizures and cerebral edema. Additional neurological emergencies covered include submersion injuries with their risk for hypoxic brain damage and long-term neurological sequelae, Reye's syndrome with its association to aspirin use in children and resulting metabolic and neurological deterioration, and the spectrum of seizure disorders encompassing various seizure types, medication management, and emergency intervention protocols. Neural tube defects including spina bifida are discussed with attention to membrane care, latex sensitivity precautions, and developmental support. The chapter also addresses developmental and behavioral disorders such as attention deficit hyperactivity disorder with behavioral strategies and medication considerations, autism spectrum disorder emphasizing communication challenges and sensory regulation needs, and intellectual disabilities including Down syndrome with adaptive functioning support and family education. Throughout the chapter, nursing priorities center on airway protection, intracranial pressure management, comprehensive neurological assessment, seizure precautions, and collaborative family-centered planning for long-term developmental and behavioral support.
