Neuropsychiatric symptoms correlated with functional trajectories among people living with Alzheimer’s disease dementia and Lewy body dementia

Functionality is one of the most important markers of wellbeing in older adults. People with dementia lose functionality mainly because of cognitive impairment. However, little has been outlined regarding the independent association of Neuropsychiatric symptoms (NPS) on functional decline in this population, especially in those diagnosed with Lewy body dementia (LBD). The aim of our work is to study the association of NPS at time of dementia diagnosis and 5‐year longitudinal course with the 5 years’ trajectory of functional decline in people with Alzheimer´s disease (AD) and LBD.
