ABSTRACT: Stress is one of the most potent of many factors that can cause
expression of behavioral and psychological symptoms of dementia (BPSD). Stress
can also increase autonomic nervous activity. This study aimed to examine the
relationships between BPSD and autonomic function in the elderly with dementia. We recruited 35
participants diagnosed with dementia from nearby geriatric
health service facilities. The Neuropsychiatric Inventory was used for the evaluation of BPSD, and a
TAS 9 VIEW (manufactured by YKC) was used for the heart rate variability
analysis to measure autonomic nervous system activity. We constructed a model in which the autonomic nervous system comprised
a category and performed a structural equation modeling analysis to calculate the standardization coefficient and correlation
coefficient for each factor. The results
showed that the influence of BPSD resulted in suppression of sympathetic
and enhancement of parasympathetic nervous system activity.
