  1. 1. Alterations in Neurologic Function in Children Joy A. Shepard, PhD(c), RN-C, CNE Joyce Buck, MSN, RN-C, CNE 1
  2. 2. Objectives Describe the anatomy and physiology of the neurologic system and pediatric differences Choose the appropriate assessment guidelines and tools to examine infants and children with altered level of consciousness and other neurologic conditions Differentiate between the signs of a seizure and status epilepticus in infants and children, and plan appropriate nursing care for each condition Plan family-centered nursing care for the child with hydrocephalus, neural tube defects, and cerebral palsy Describe the nursing management for traumatic brain injury 2
  3. 3. Overview of the Neurologic System 3
  4. 4. Nervous System Consists of the brain, spinal cord, and nerves Seat of intellect and reasoning Communication and coordination system of the body Affects and is affected by all other body systems 4
  5. 5. Figure 27-1 Transverse section of the brain and spinal cord. Knowledge of the anatomy of the brain is helpful in understanding the symptoms of neurologic dysfunction. 5
  6. 6. 6
  7. 7. Cranial Nerves 12 pairs, begin in the brain Many important sensory and motor functions Designated by number and name: I, III II, IV, VI III, VIII V,VII IX, X, XII 7

  9. 9. 9
  10. 10. 10
  11. 11. Spinal Nerves 31 pairs: originate at spinal cord and go through openings in vertebrae Convey sensory information; relay impulses that stimulate motor responses Send and receive information to specific body locations 11
  12. 12. Neuron/ Nerve Impulse Neuron: information processing cells; basic cells of nervous system Make connections with other neurons to form the information processing networks A stimulus creates an impulse The impulse travels into the neuron on the dendrite (s) and out on the axon At the end of the axon, a neurotransmitter is released that carries the impulse across the synapse to the next dendrite 12
  13. 13. Neurilemma (Myelin Sheath) Covering that speeds up the nerve impulse along the axon Myelin is a fatty protein substance that protects the axon Synapse- space between neurons, messages go from one cell to the next Responsible for speed and accuracy of nerve impulses 13
  14. 14. Myelination Progressive covering of axons with layers of myelin Incomplete at birth Proceeds in cephalocaudal direction Accounts for progressive acquisition of gross and fine motor skills, coordination Axon diameters and myelin sheaths undergo conspicuous growth during the first two years of life, but may not be fully mature until a person’s early 20s 14
  15. 15. Cephalocaudal/ Proximodistal 15
  16. 16. Pediatric Differences 16
  17. 17. Anatomic Differences in the Structures of the Nervous System Between Children and Adults (p. 850) 17
  18. 18. Anatomic & Physiologic Differences 18
  19. 19. Neurological System of Children Complete but immature nervous system Top heavy Cranial bones- thin, not well developed Brain highly vascular with small subarachnoid space Excessive spinal mobility Wedge-shaped cartilaginous vertebral bodies 19
  20. 20. “Top Heavy” 20
  21. 21. Unfused Sutures Fibrous union of suture lines and interlocking of edges occurs by 6 months Suture lines between skull bones ossified by age 12 Posterior fontanel closes by 3 months Anterior fontanel closes by 18 to 24 months Prone to brain injury and skull fractures with falls 21
  22. 22. Rapidly-Developing Brain At birth, brain is 25% of adult size Develops rapidly until age 4 Brain increases four-fold in size during preschool period By age 6, brain is 90% of adult size Myelination is complete by early adulthood 22
  23. 23. 23
  24. 24. Developmental Differences Neurological assessment of the child is limited to the child’s developmental level Children progress cognitively through the sensorimotor, preoperational, concrete operational, and formal operational stages Primitive reflexes present at birth disappear by 1 year Children are developing their ability to recognize and manage their emotions or feelings up until and including their late teens or early twenties Children and adolescents are still in a period of social development which involves learning the values, knowledge and skills that enable them to relate to others Adolescents cannot reason as well as adults; they are more inclined to act impulsively and irrationally and take part in high-risk behaviors 24
