Caregiver burden associated with behavioral and psychological symptoms of dementia in elderly people in the local community
Matsumoto N, Ikeda M, Fukuhara R, Shinagawa S, Ishikawa T, Mori T, Toyota Y, Matsumoto T et al.. Dementia and geriatric cognitive disorders, 2007-02-09
Topic: Risk, prevention and care in population studies
Background Despite many studies about the association between caregiver burden and behavioral and psychological symptoms of dementia (BPSD), there have been no population-based studies to evaluate caregiver burden associated with each BPSD. Objective To evaluate caregiver burden associated with the individual BPSD in elderly people living in the community. Methods The subjects were 67 participants with dementia living with their caregivers (diagnosed in the third Nakayama study): 51 Alzheimer's disease, 5 vascular dementia and 11 other. The Neuropsychiatric Inventory (NPI) and NPI Caregiver Distress Scale (NPI-D) were used to assess subjects' BPSD and related caregiver distress, respectively. Results In the subjects exhibiting BPSD, aberrant motor behavior had the highest mean NPI score, and depression/dysphoria had the lowest. Agitation/aggression had the highest mean NPI-D score, and euphoria/elation had the lowest. Delusion, agitation/aggression, apathy/indifference, irritability/lability and aberrant motor behavior showed a correlation between the NPI and NPI-D scores. Conclusion The burden associated with BPSD is different for each symptom and does not always depend on frequency and severity of BPSD. These findings suggest that some symptoms, such as agitation/aggression and irritability/lability, may affect the caregivers significantly, although their frequency and severity are low.
Key findings
- Background Despite many studies about the association between caregiver burden and behavioral and psychological symptoms of dementia (BPSD), there have been no population-based studies to evaluate caregiver burden associated with each BPSD.
- Objective To evaluate caregiver burden associated with the individual BPSD in elderly people living in the community.
- Results In the subjects exhibiting BPSD, aberrant motor behavior had the highest mean NPI score, and depression/dysphoria had the lowest.
- Conclusion The burden associated with BPSD is different for each symptom and does not always depend on frequency and severity of BPSD.
- These findings suggest that some symptoms, such as agitation/aggression and irritability/lability, may affect the caregivers significantly, although their frequency and severity are low.
Why it matters
In 67 people with dementia living in the community, the burden on caregivers differed by symptom and did not always depend on how frequent or severe the symptom was. Symptoms such as agitation/aggression and irritability/lability may affect caregivers significantly even when their frequency and severity are not high.
