Abstract
In this cross-sectional, observational study, the association between lethargy and vagal tone was analyzed in thirteen low-risk preterm infants. Infants underwent behavioral assessment and vagal tone measurement indexed by high-frequency heart-rate variability (HF-HRV). A lower vagal tone cluster was associated with greater lethargy (p = .05), reduced handling (p = .003), excitability (p = .006), higher skin stress indicators (p = .13), and central nervous system stress indicators (p = .10) than cluster with a higher vagal tone cluster. A lower vagal tone could indicate autonomic nervous system dysregulation or immaturity, leading to neurobehavioral challenges, such as lethargy and further neurodevelopmental difficulties.
期刊介绍:
Devoted to exploring relationships between brain and behavior across the life span, Developmental Neuropsychology publishes scholarly papers on the appearance and development of behavioral functions, such as language, perception, and social, motivational and cognitive processes as they relate to brain functions and structures. Appropriate subjects include studies of changes in cognitive function—brain structure relationships across a time period, early cognitive behaviors in normal and brain-damaged children, plasticity and recovery of function after early brain damage, the development of complex cognitive and motor skills, and specific and nonspecific disturbances, such as learning disabilities, mental retardation, schizophrenia, stuttering, and developmental aphasia. In the gerontologic areas, relevant subjects include neuropsychological analyses of normal age-related changes in brain and behavioral functions, such as sensory, motor, cognitive, and adaptive abilities; studies of age-related diseases of the nervous system; and recovery of function in later life.
Empirical studies, research reviews, case reports, critical commentaries, and book reviews are featured in each issue. By publishing both basic and clinical studies of the developing and aging brain, the journal encourages additional scholarly work that advances understanding of the field of lifespan developmental neuropsychology.
