    Abstract:
    INTRODUCTION: We aimed to evaluate how the presence of individual neuropsychiatric symptoms in non-institutionalised patients with dementia is associated with caregiver burden of their informal caregivers, family members. METHODS: We performed a cross-sectional study on a total of 131 pairs of one informal caregiver family member and non-institutionalised patient with dementia in a family medicine practices in a city of Zagreb, Croatia. Caregiver measures included Zarit Burden Interview (ZBI) whereas patient measures included Mini mental state examination (MMSE), Barthel index and Neuropsychiatric Inventory Questionnaire (NPI-Q). RESULTS: Total NPI-Q score explained 21% of overall burden. In order of strength of the association, after adjustments for age, sex, MMSE and Barthel index, overall burden was significantly associated with higher NPI-Q scores for agitation/aggression, apathy/indifference, irritability/lability, disinhibition, motor disturbance, appetite/eating, depression/dysphoria, anxiety, elation/euphoria and nighttime behaviours. When evaluating mutually independent contribution of unique NPI-Q symptoms to caregiver burden, agitation/aggression and apathy/indifference remained only two mutually independently associated symptoms, each explaining 5% of overall burden in this context. CONCLUSIONS: Informal caregivers who provide for family members with dementia suffering from agitation/aggression or apathy/indifference should be recognised as under special risk for the development of caregiver burden and considered as candidates for early targeted interventions.
