Abstract
Neuropsychiatric symptoms (NPS) are one of the most challenging issues in the management and care of people with dementia. Their accurate assessment is thus crucial for properly approaching subjects with cognitive disorders in the clinical setting. In parallel, the correct evaluation of NPS is also particularly relevant in the research field where they serve as critical indicators for measuring the efficacy of interventions against cognitive disorders. However, the study of NPS is extremely challenging given their extreme inter- and intra-individual variability. Moreover, the available assessment tools are often inadequate to fully capture their complexity and phenotypic expression. Based on these considerations, novel modalities for the assessment and measurement of NPS may be important to identify and develop. In this regard, a promising alternative (or, at least, a complementary aid) to traditional scales and questionnaires might be constituted by diaries. In the present article, we discuss the potential advantages and implications that may result from the adoption of this kind of instruments for the ecological assessment of NPS in subjects with dementia.
