13.6 Lifespan Considerations

Newborn

At birth, the neurologic system is not fully developed. The brain is still developing, and the newborn’s anterior fontanelle doesn’t close until approximately 18 months of age. The sensory and motor systems gradually develop in the first year of life. The newborn’s sensory system responds to stimuli by crying or moving body parts. Initial motor activity is primitive in the form of newborn reflexes. Additional information about newborn reflexes is provided in the “Assessing Reflexes” section. As the newborn develops, so do the motor and sensory integration.

Pediatrics

Depending on the child’s age and developmental level, they may answer questions independently or the child’s parent/guardian may provide information. The assessment recognizes developmental monitoring for the neurological system. Refer to the following link for additional monitoring and screening.

Older Adults

The aging adult experiences a general slowing in nerve conduction, resulting in a slowed motor and sensory interaction. Fine coordination, balance, and reflex activity may be impaired. There may also be a gradual decrease in cerebral blood flow and oxygen use that can cause dizziness and loss of balance.
