Dementia Day Care Centres (DDCCs) are defined as services providing care and rehabilitation to people with dementia associated with behavioural and psychological symptoms (BPSD) in a semi-residential setting. According to available evidence, DDCCs may decrease BPSD, depressive symptoms and caregiver burden. The present position paper reports a consensus of Italian experts of different disciplines regarding DDCCs and includes recommendations about architectural features, requirements of personnel, psychosocial interventions, management of psychoactive drug treatment, prevention and care of geriatric syndromes, and support to family caregivers. DDCCs architectural features should follow specific criteria and address specific needs of people with dementia, supporting independence, safety, and comfort. Staffing should be adequate in size and competence and should be able to implement psychosocial interventions, especially focused on BPSD. Individualized care plan should include prevention and treatment of geriatric syndromes, a targeted vaccination plan for infectious diseases including COVID-19, and adjustment of psychotropic drug treatment, all in cooperation with the general practitioner. Informal caregivers should be involved in the focus of intervention, with the aim of reducing assistance burden and promoting the adaptation to the ever-changing relationship with the patient.

Objectives Few studies have analyzed factors associated with delirium subtypes. In this study, we investigate factors associated with subtypes of delirium only in patients with dementia to provide insights on the possible prevention and treatments. Design This is a cross-sectional study nested in the “Delirium Day” study, a nationwide Italian point-prevalence study. Setting and Participants Older patients admitted to 205 acute and 92 rehabilitation hospital wards. Measures Delirium was evaluated with the 4-AT and the motor subtypes with the Delirium Motor Subtype Scale. Dementia was defined by the presence of a documented diagnosis in the medical records and/or prescription of acetylcholinesterase inhibitors or memantine prior to admission. Results Of the 1057 patients with dementia, 35% had delirium, with 25.6% hyperactive, 33.1% hypoactive, 34.5% mixed, and 6.7% nonmotor subtype. There were higher odds of having venous catheters in the hypoactive (OR 1.82, 95% CI 1.18-2.81) and mixed type of delirium (OR 2.23, CI 1.43-3.46), whereas higher odds of urinary catheters in the hypoactive (OR 2.91, CI 1.92-4.39), hyperactive (OR 1.99, CI 1.23-3.21), and mixed types of delirium (OR 2.05, CI 1.36-3.07). We found higher odds of antipsychotics both in the hyperactive (OR 2.87, CI 1.81-4.54) and mixed subtype (OR 1.84, CI 1.24-2.75), whereas higher odds of antibiotics was present only in the mixed subtype (OR 1.91, CI 1.26-2.87). Conclusions and Implications In patients with dementia, the mixed delirium subtype is the most prevalent followed by the hypoactive, hyperactive, and nonmotor subtype. Motor subtypes of delirium may be triggered by clinical factors, including the use of venous and urinary catheters, and the use of antipsychotics. Future studies are necessary to provide further insights on the possible pathophysiology of delirium in patients with dementia and to address the optimization of the management of potential risk factors.

The prognostic role of high blood pressure and the aggressiveness of blood pressure lowering in dementia are not well characterized. To assess whether office blood pressure, ambulatory blood pressure monitoring, or the use of antihypertensive drugs (AHDs) predict the progression of cognitive decline in patients with overt dementia and mild cognitive impairment (MCI). Cohort study between June 1, 2009, and December 31, 2012, with a median 9-month follow-up of patients with dementia and MCI in 2 outpatient memory clinics. Cognitive decline, defined as a Mini-Mental State Examination (MMSE) score change between baseline and follow-up. We analyzed 172 patients, with a mean (SD) age of 79 (5) years and a mean (SD) MMSE score of 22.1 (4.4). Among them, 68.0% had dementia, 32.0% had MCI, and 69.8% were being treated with AHDs. Patients in the lowest tertile of daytime systolic blood pressure (SBP) (≤128 mm Hg) showed a greater MMSE score change (mean [SD], -2.8 [3.8]) compared with patients in the intermediate tertile (129-144 mm Hg) (mean [SD], -0.7 [2.5]; P = .002) and patients in the highest tertile (≥145 mm Hg) (mean [SD], -0.7 [3.7]; P = .003). The association was significant in the dementia and MCI subgroups only among patients treated with AHDs. In a multivariable model that included age, baseline MMSE score, and vascular comorbidity score, the interaction term between low daytime SBP tertile and AHD treatment was independently associated with a greater cognitive decline in both subgroups. The association between office SBP and MMSE score change was weaker. Other ambulatory blood pressure monitoring variables were not associated with MMSE score change. Low daytime SBP was independently associated with a greater progression of cognitive decline in older patients with dementia and MCI among those treated with AHDs. Excessive SBP lowering may be harmful for older patients with cognitive impairment. Ambulatory blood pressure monitoring can be useful to help avoid high blood pressure overtreatment in this population.

Objective: Recent guidelines have widened clinical indications for out-of-office blood pressure measurement, including home blood pressure monitoring and ambulatory blood pressure monitoring (ABPM), suggesting the latter as recommended method in cognitively impaired patients. There is, however, a widespread belief that ABPM could be poorly tolerated in dementia, often leading to withdraw from its use in these patients. Aim: To assess the actual tolerability of ABPM in a group of cognitively impaired elderly, affected by dementia or mild cognitive impairment (MCI). Methods: We evaluated 176 patients aged 65 + years, recruited in two different memory clinics, with a Mini Mental State Examination (MMSE) between 10 and 27. Behavioral and psychological symptoms were assessed with Neuropsychiatric Inventory (NPI). A patient was considered tolerant if able to keep the device on continuously for 24 h. The minimum number of correct measurements required was 70% of the predicted total number. Results: 16% of patients wore the device for less than 24 h. Dividing the study population in tertiles of MMSE performance, 29% failed to tolerate the device in the lowest, 12% in the middle and 7% in the highest tertile (p < 0.01). Dividing the study population in tertiles of NPI performance, 30% of patients failed in the highest, 19% in the middle and 8% in the lowest tertile (p = 0.02); 31% of patients who tolerated the device did not achieve the minimum number of measurements required, with a mean number of 63% of predicted measurements. Conclusion: The ABPM proved a generally well-tolerated technique even in cognitively impaired elderly. Only a minority of subjects with poorer cognitive performances and greater behavioral symptoms did not tolerate the monitoring. Among most patients who failed to achieve the minimum number of measurements needed, the number of valid measurements was very close to the minimum required.

To assess the effects of Day Care (DC) on older subjects with dementia and their caregivers. Thirty patients with dementia, consecutively admitted to a DC, were compared with 30 patients, matched for age and cognitive function, who received usual home care (HC). Primary caregivers were compared as well. At baseline and after 2 months, patients were assessed for cognitive and functional status, behavioral and psychological symptoms [Neuropsychiatric Inventory (NPI)] and psychotropic drugs use, and caregivers were evaluated for care burden [Caregiver Burden Inventory (CBI)] and depressive symptoms. After adjusting for potential confounders, NPI score significantly decreased in DC group, with a reduction of psychotropic drugs prescription, whereas it increased in HC. No significant between-group difference was observed for cognitive and functional change. CBI significantly decreased in DC, but not HC, caregivers, with no significant between-group difference in depressive symptoms change. A 2-month period of DC assistance is effective in reducing behavioral and psychological symptoms of dementia patients and in alleviating caregivers' burden.

Objective: To assess the effects of Day Care (DC) service on older demented subjects and on caregivers' burden. Methods: We included in the study 21 subjects with dementia (according to DSMIV criteria), consecutively assigned by the Geriatric Evaluation Unit of Pistoia to the DC "Monteoliveto" (DC group), and 21 subjects, matched for age and Mini Mental State Examination (MMSE) score, who received usual home care (HC group). Patients and caregivers were evaluated at baseline and after two months. Patients were evaluated for: social and environmental setting, comorbidity, psychotropic drug use, cognitive impairment (MMSE), functional status (Basic and Instrumental Activities of Daily Living - BADL, IADL), and behavioral and psychological symptoms (Neuropsychiatric Inventory - NPI). Caregivers were evaluated for family and work setting, hours of assistance and assistance burden (Caregiver Burden Inventory - CBI). Results: At baseline, no significant difference was observed between patients and caregivers in the two groups. After two months NPI decreased in DC and increased in HC (DC -5.8 ± 3.1 vs. HC +7.7 ± 3.2, p = 0.004), whereas changes in psychotropic drugs prescription were comparable between the two groups; in particular, a significant difference was observed for anxiety, that decreased in DC and increased in HC group. Changes in MMSE, BADL, and IADL scores after two months were comparable between the two groups. Among caregivers, a significant reduction of CBI score was observed in the DC group compared to HC after two months (DC -8.1 ± 2.0 vs. HC -0.5 ± 2.1, p = 0.005). All results were adjusted for age, gender and baseline value of each variable. Conclusions: Short-term DC assistance is effective in reducing behavioral and psychological symptoms of demented subjects and in alleviating caregivers' burden.

Clinical trials have demonstrated the efficacy of cholinesterase inhibitors (ChEI) in improving cognitive status and disability in subjects with mild to moderate Alzheimer's disease (AD). However, little is known about the effectiveness of ChEI in clinical practice, and no large clinical trials comparing different ChEI are available at present. Aim of this study was to evaluate safety and effectiveness of ChEI in a sample of elderly outpatients diagnosed with mild to moderate AD. We selected 407 subjects for ChEI treatment (donepezil,rivastigmine or galantamine). Their cognitive function was evaluated by means of the mini mental state examination (MMSE), and the global functional status was estimated by using the activities of daily living (ADL) and the instrumental activities of daily living (IADL) scales at baseline (To), then after 1 (T1), 3 (T2) and 9 months (T3), respectively. T3 follow-up was completed by 212 subjects. The patients were considered as responders (R), if the MMSEscore at T2 was unchanged or improved, if compared to that of T0. In 35 patients (8.6 %)treatment was withdrawn because of mostly gastrointestinal adverse events. Compared to the other drugs, donepezil was associated with a lower incidence of withdrawals due to adverse events. Subjects who completed T3 follow-up (age 78 +/- 6 years, MMSE scores 18.8 +/- 3.9) showed an increase at T2 of 0.7 +/- 2.7 (p = 0.001) and a decrease at T3 of -0.6 +/- 3.4 (p = 0.008) in the MMSE scores, as compared to To . The ADL and IADL scores did not show significant changes at T2; however, both decreased significantly at T3. The patients Rat-T2 showed a better cognitive and functional outcome at T3 , compared to the nonresponders(NR-at-T2), displaying values of MMSE R-at-T2 0.4 +/- 3.1 vs. NR-at-T2 -3.0 +/- 2.5, p = 0.001, and ADL values of -0.3 +/- 1.2 vs. -0.7 +/- 1.3, p = 0.03, respectively. No significant difference was found in the changes of MMSE scores between donepezil and rivastigmine (galantamine was not included in the comparison due to the small number of treated subjects). In conclusion, in this sample of elderly subjects with mild to moderate AD,treated with ChEI, a small but significant decline in cognitive and functional status was observed after 9 months. Subjects who showed a good response to treatment after 3 months, had a better cognitive and functional outcome at 9 months. No significant difference in cognitive outcome was found between drugs, while donepezil was better tolerated.
