Prevalence and Correlates of Behavioral Disorders in Old Age Subjects with Cognitive Impairment: Results from the ReGAl Project

Background: Presence of behavioral and psychological symptoms of dementia (BPSD) is very common in subjects with cognitive impairment, representing an important determinant of disease progression, institutionalization, and worse prognosis. Knowledge of the prevalence and correlates of BPSD in community-living old subjects with cognitive impairment is limited so far, but it is essential for establishing specifically tailored care and cure in such a vulnerable population. Objective: With this study, we aimed at investigating, in a large sample of old age subjects with cognitive impairment, BPSD prevalence and correlates including the main demographic, clinical, and socio-environmental characteristics. Methods: Data were gathered from the ReGAl project (Rete Geriatrica Alzheimer; Geriatric Network on Alzheimer's disease), a large longitudinal Italian multicentric clinical-based study, promoted by the Italian Society of Gerontology and Geriatrics (SIGG). Results: We evaluated data from 4,157 old-age subjects affected by mild cognitive impairment (MCI) (541; 13%) or dementia (3616; 87%). 85.2% of all the population presented with at least one BPSD. Using a factor analysis, we identified four factors of BPSD: psychotic, affective, maniac, and impulse control behaviors. Logistic regression analyses revealed that among the main demographic, clinical, and socio-environmental aspects considered, only comorbidity was associated with all factors, independently of multiple covariates. Conclusion: Identification of BPSD is crucial in everyday clinical practice and necessary to develop specific interventions and to define appropriate outcomes in their management. BPSD occur in a complex psychopathological context, influenced by several demographic and environmental factors that must be taken into account for a correct diagnosis and treatment

Normative data for the ACE-R in an Italian population sample

The Addenbrooke's Cognitive Examination Revised (ACE-R) is a brief cognitive screening instrument also proposed to detect mild cognitive impairment, a high-risk condition for Alzheimer's disease and other forms of dementia. In this study, we report normative data on the ACE-R-Italian version, collected on a sample of 264 Italian healthy subjects aging between 60 and 93 years, and with a formal education from 1 to 19 years. The global normal cognition was established in accordance with the Italian version of the Mini-Mental State Examination score and with exclusion criteria derived by a consensus process. Linear regression analysis was performed to evaluate the effect of age, gender, and education on the ACE-R total performance score. We provide correction grids to adjust raw scores and equivalent scores with cut-off value to allow comparison between ACE-R performance and others neuropsychological test scores that can be administered to the same subject.6 page(s

Delirium in nursing home residents: is there a role of antidepressants? A cross sectional study.

Background: Delirium is strongly associated with poor health outcomes, yet it is frequently underdiagnosed. Limited research on delirium has been conducted in Nursing Homes (NHs). Our aim is to assess delirium prevalence and its associated factors, in particular pharmacological prescription, in this care setting. Methods: Data from the Italian "Delirium Day" 2016 Edition, a national multicenter point-prevalence study on patients aged 65 and older were analyzed to examine the associations between the prevalence of delirium and its subtypes with demographics and information about medical history and pharmacological treatment. Delirium was assessed using the Assessment test for delirium and cognitive impairment (4AT). Motor subtype was evaluated using the Delirium Motor Subtype Scale (DMSS). Results: 955 residents, from 32 Italian NHs with a mean age of 84.72 ± 7.78 years were included. According to the 4AT, delirium was present in 260 (27.2%) NHs residents, mainly hyperactive (35.4%) or mixed subtypes (20.7%). Antidepressant treatment with selective serotonin reuptake inhibitors (SSRIs) was associated with lower delirium prevalence in univariate and multivariate analyses. Conclusions: The high prevalence of delirium in NHs highlights the need to systematically assess its occurrence in this care settings. The inverse association between SSRIs and delirium might imply a possible preventive role of this class of therapeutic agents against delirium in NHs, yet further studies are warranted to ascertain any causal relationship between SSRIs intake and reduced delirium incidence
