Subjective memory complaints in Italian elderly with mild cognitive impairment: implication of psychological status

Subjective cognitive and memory complaints (SMC) are common in later life and are considered an indicator for progression to cognitive decline. The aim of the present study was to identify the relationship among SMC, neuropsychiatric symptoms and psychological aspects in elderly subjects with mild cognitive impairment (MCI) as well as to analyse the effect on SMC of a comprehensive cognitive training. Data from a sample of 94 patients enrolled in ‘My Mind Project’ (Grant No. 154/GR-2009-1584108) were collected. The study evidenced that depression was a significant predictor of SMC and that after the training, the number of subjects with SMC was significantly reduced in the experimental group in comparison to the control one. These results suggest that the participation in cognitive stimulation protocols may improve the perception of SMC in subjects with MCI

Increased nocturnal urinary cortisol levels in the elderly patients with depression, coexisting major geriatric syndromes and combined pathogenetic mechanisms

Background: The mechanisms at the basis of depression are still matter of debate, but several studies in the literature suggest common pathways with dementia (genetic predispositions, metabolic and inflammatory mechanisms, neuropathological changes) and other geriatric syndromes. Aims: To evaluate the role of cortisol (as marker of the HPA, hypothalamus–pituitary–adrenal axis hyperactivity) in elderly subjects with depressive symptoms (by the means of the AGICO, AGIng and COrtisol, study), in relationship to the presence of the major geriatric syndromes. Methods: The AGICO study enrolled patients from ten Geriatric Units in Italy. Every subject received a comprehensive geriatric assessment or CGA (including the Mini Mental State Examination or MMSE, Geriatric Depression Scale or GDS and Cornell Scale for Depression in Dementia or CSDD), the neurological examination (with a computed tomography scan or magnetic resonance imaging of the brain), the assessment of the metabolic syndrome (MetS), the evaluation of the cortisol activity by two consecutive urine collections (diurnal and nocturnal), a CGA-derived frailty index (FI) and a modified measure of allostatic load (AL). Results: The MMSE scores were significantly and inversely related to the values of GDS (p < 0.001) and CSDD (p < 0.05), respectively. The patients with depressive symptoms (GDS/CSDD > 8) showed significantly increased disability, MetS, inflammation, FI and AL and significantly reduced MMSE and renal function. The diurnal and nocturnal urinary cortisol levels in the patients with depressive symptoms (GDS/CSDD > 8) were higher with respects to controls (p < 0.05 for nocturnal difference). Discussion: The AGICO study showed that the stress response is activated in the patients with depression. Conclusion: The depression in elderly patient should be reconsidered as a systemic disease, with coexisting major geriatric syndromes (disability, dementia, frailty) and combined pathogenetic mechanisms (metabolic syndrome, impaired renal function, low-grade inflammation, and allostatic load). Cortisol confirmed its role as principal mediator of the aging process in both dementia and metabolic syndrome

Design and methodology of the screening for CKD among older patients across Europe (SCOPE) study: A multicenter cohort observational study

Background: Decline of renal function is common in older persons and the prevalence of chronic kidney disease (CKD) is rising with ageing. CKD affects different outcomes relevant to older persons, additionally to morbidity and mortality which makes CKD a relevant health burden in this population. Still, accurate laboratory measurement of kidney function is under debate, since current creatinine-based equations have a certain degree of inaccuracy when used in the older population. The aims of the study are as follows: to assess kidney function in a cohort of 75+ older persons using existing methodologies for CKD screening; to investigate existing and innovative biomarkers of CKD in this cohort, and to align

Association between Cognitive Status and Physical Activity: Study Profile on Baseline Survey of the My Mind Project

Background: The incidence of people with dementia is expected to increase significantly in the coming years, but it seems that there is a relationship between an active lifestyle and cognitive decline. The present study aimed to compare the characteristics and engagement in the physical activity (PA) of three groups of Italian elderly with different cognitive statuses at baseline phase. Methods: Data were examined using the results from the “My Mind Project” on 305 community-dwelling Italians. The sample was comprised of 93 subjects with Alzheimer’s disease (AD), 109 with mild cognitive impairment (MCI) and 103 healthy elderly (HE). Results: Classification of subjects on the basis of Physical Activity Scale for the Elderly (PASE) score showed that 47% of HE performed the highest level of physical activity while 40% of AD performed the lowest level. MCI subjects were distributed quite homogeneously across the levels (p < 0.001). Physical activity such as walking and light sports was carried out mainly and more frequently by HE as compared to the others (p < 0.05). As regards functional status, AD presented worse conditions in basic and instrumental activities of daily living than the other groups (p < 0.001). Conclusions: Our results evidenced that subjects with cognitive decline had the tendency to engage in PA less than HE. In particular, age and education negatively affected engagement in PA

Study of the effects of adapted Tango and multidimensional intervention in pREvention of dementia in agiNG: developing healTHy lifestyle programs (STRENGTH Project)—the experimental protocol of a prospective randomised controlled trial

Abstract Background Dementia represents a key health issue for older adults, with negative consequences on psycho-social and functional status. Treatments that counteract cognitive deficits in mild cognitive impairment (MCI) are needed to prevent or delay it. Aim To describe the experimental protocol of the STRENGTH Project. This study investigates a multimodal intervention in older adults with MCI to improve cognitive, functional, biochemical and psycho-social aspects. Methods The prospective randomised controlled trial will enrol 300 subjects with MCI (age ≥ 60 years). Participants will be randomly assigned to: (a) the experimental group, which will undergo sessions of adapted tango, music therapy, engagement in social activities, cognitive intervention and psycho-education for 6 months or (b) the control group, which will receive psycho-education and advice on healthy lifestyle for 6 months. All outcomes will be analysed before intervention (baseline), immediately after termination (follow-up 1), after 6 months (follow-up 2) and after 2 years (follow-up 3). Discussion We expect that the findings of this multidisciplinary study will be useful to optimize clinical and psycho-social interventions for improving cognitive and functional status of subjects with MCI. Conclusions This project could have a meaningful impact on National Health Systems by providing clues on multidisciplinary management of older adults affected by cognitive decline to prevent dementia. </jats:sec

Effect of a Comprehensive Intervention on Plasma BDNF in Patients with Alzheimer’s Disease

A comprehensive intervention (CI) on patients with Alzheimer’s disease was assessed by measuring plasmabrain-derived neurotrophic factor (pBDNF) and ADAS-Cog score (ADAS-Cog(score)) before, immediately after (FU1), and 6 (FU2) and 24 months (FU3) after the CI. Baseline pBDNF was higher in patients with moderate AD (but not mild AD) than in healthy controls. At FU1, pBDNF and ADAS-Cog(score) decreased significantly. At FU2 and FU3, patients’ cognitive status worsened and pBDNF further increased versus baseline, suggesting that CI interruption may be a stress event that prevents return to homeostasis. CI exerted positive short-term effects, but more information is needed on long-term consequences

Malnutrition and Left Ventricular Systolic Function in Hospitalized Elderly Patients with and without Heart Failure

Heart failure (HF) is highly prevalent among older subjects and it is associated with poor prognosis. HF frequently coexists with malnutrition. Objectives of our work were to assess nutritional status of old inpatients with and without HF and to study the association of malnutrition markers with echocardiographic parameters of left ventricular function and geometry. We enrolled 165 patients (72 men, 93 women; mean age: 80±7 years) consecutively admitted to Cardiology ward of our geriatric research hospital. For all subjects we performed clinical examination, echocardiogram and laboratory tests. Nutritional status was assessed evaluating anthropometric and laboratory markers of malnutrition (BMI ≤ 24 kg/m2 and/or serum albumin ≤ 3.2 g/dL). We found high prevalence of HF (67.3%) and malnutrition (28.5%). Mean serum albumin and mean BMI were 3.6±0.5 g/dL and 25.8±5.2 kg/m2 respectively. T-Student tests showed lower values of serum albumin in patients with HF compared with patients without HF (3.5±0.6 g/dL vs 3.7±0.4 g/dL; p:0.043). Conversely BMI values were not significantly different. We found significant association between serum albumin and ejection fraction (EF) of left ventriculum (r:0.311; p:0.001). An independent correlation between EF and serum albumin was confirmed by multivariate analysis (β:0.301; p:0.027). Our study highlights that malnutrition is common among elderly inpatients with HF. Lower albumin was associated with worse systolic left ventricular function. Efforts should be made in the research setting to better understand the pathophysiology of malnutrition in HF and to identify useful management strategies for nutritional assessment and supplementation
