The improvement in cognitive performances due to cholinesterase inhibitors (ChEls) is not homogeneous among Alzheimer's disease (AD) subjects. Aim of this study is to evaluate whether a specific pattern of change in mini mental state examination (MMSE) could be observed in AD subjects after 9-month treatment with ChEls. From September 2000 to September 2002, 99 subjects enrolled in the CRONOS project. They have never been previously treated with ChEls. All of them completed both the 3- and the 9-month follow-up. The multidimensional assessment included MMSE, activity of daily living (ADL), instrumental activity of daily living (IADL), somatic health status, according to design of the CRONOSproject. The MMSE was analyzed both as a total score and disaggregated in 11 items. All subjects were divided in 2 groups according to the degree of change in MMSE total score from baseline to the 9th month. Subjects with a change 0 as responders (R). At start, no statistically significant differences were found between the 2 groups. MMSE score was significantly higher in the R group both at 3 (p < 0.0001) and 9 months (p < 0.0001), while functional status (ADL and IADL) was significantly lower in NR group at 9 months (p = 0.025; p =0.018, respectively). In MMSE qualitative analysis of 3-month, NR significantly worsened in temporal (p

The purpose of this study was to investigate the pattern of cognitive impairment in mild Alzheimer's disease (AD). We tested thirty patients (10 men and 20 women) with mini mental state examination (MMSE) scores between 20 and 24. The mental deterioration battery (MDB) was administered to all subjects. For each patient, the mean general score for the 4 verbal and the 4 non-verbal items were calculated, in order to verify the existence of a significant difference between them. In our sample the results showed that the difference between verbal and non-verbal items was not significant, i.e., the disease seems to affect both domains uniformly.

Vascular dementia (VD) has not to be considered anymore as a univocal nosologic entity. Based on different types of lesions, distinct subtypes of vascular dementia may be identified, each caused by diverse pathophysiological mechanisms. Among these subtypes subcortical vascular dementia (SVD) may represent a well-defined entity in terms of pathophysiology, clinical features and neuroradiological aspects. The picture is characterized by history of arterial hypertension and other vascular risk factors, clinical symptoms and signs including, besides dementia, dysfunctions related to subcortical-frontal circuit damages, and extensive confluent or diffuse abnormalities in the subcortical brain white matter, small deep infarcts as revealed by computed tomographic (CT) or magnetic resonance imaging (MRI) scans. The homogeneity of this clinical-pathological picture is essential for the success of controlled clinical trials in the field of vascular dementia.

In Western countries data from clinical and epidemiological studies have induced the public health offices to promote a great deal of advertising and informative campaigning for smoking reduction. Cigarette smoking has been clearly linked to the most common causes of death in the elderly and contributes to the higher death rate and disability rate associated with many chronic illnesses that are common in this age group. The combination of smoking along with other risk factors like hypertension and diabetes increase high frequency diseases, disability as well as adding to an increase in mortality rate. In order to verify if a healthy lifestyle really favors longevity and how much smoking is incompatible with extreme longevity we investigated the prevalence of smokers and the total smoking exposure of a sample of centenarians in relation with residual survival and health conditions. Our sample consists of 157 centenarians living in Rome, 39 males and 118 females (ratio m/f =1:3),mean age being 101.59 +/- 1.8 years (+/-SD), 83.8% of the centenarians have never smoked,13.5 % are former smokers, and 2.7% are active smokers. The average starting age of smoking is 21.2 years, while the average age of quitting is 65.7 years with an average of 44.7 +/- 17.1 smoking years. The average number of smoked cigarettes per day is quite low,less than 10 cigarettes, so that the total average number of smoked cigarettes is 158,045,well under 280,000 which is considered the cut-off point in many studies of when tumors are noticed. There seemed to be a significant difference (p < 0.001) in gender results in smokers: among male centenarians smokers reached 46%, while female smoker centenarians reached only 8.1%. Statistically significant chronic illnesses were noted among centenarian smokers over the age of 65 (p < 0.02). Moreover, Cox's regression has shown in centenarians a lower survival rate (p < 0.05) in smokers (20.7 +/- 11.2 months) than in non-smokers (27.0 +/- 19.0 months). In conclusion, our study evidences that smoking is for all but some exceptional subjects, incompatible with successful aging and compromises life expectancy even in extreme longevity.

The diagnosis of depression by clinical interview may be difficult in the patients with communication problems (aphasia, severe cognitive impairment or severe deafness). In these cases, depressive symptoms may be observed by others (nurses and caregivers). The aim of this study was to evaluate the clinical usefulness of an observational scale to identify depression in older patients. Seventy-six institutionalized patients in an intermediate-long-term care center were evaluated. Of them, 39 were excluded because they were unable to perform a clinical interview, needed to diagnose depression. Of the excluded patients, 18 had aphasia, 7 showed severe cognitive impairment: their mini mental state examination (MMSE) score < 14, and 14 collaborated very poorly. Thus 37 patients were analyzed, mean age was 83 +/- 0.86 years (30 women and 7 men). Diagnostic categories were: neurological 16 patients (43.2%), fractures/orthopedics 6 (16.2%), pulmonary/cardiology 5 (13.5%) and others 10 (27.1%). The mean Barthel index was 57.0 +/- 31.6 and mean MMSE score was 21.1 +/- 4.3. The observational scale (OS) designed with six items, was applied to all patients. Each item was scored as never (0 points), sometimes (1 point) and always (2 points). Thus total OS score ranged from 0 to 12. Two observers, who knew the patients (nurses), applied the OS. A trained geriatrician, using the 15-item geriatric depression scale (GDS) performed detection of depressive symptoms. There were 15 patients (40.5 %) with depression on the GDS. OS scale score with a cutoff point of 5 or more was present in 13 patients; nine of them had depression (69.2 %). In the remaining 24 patients with an OS score < 5, depression was present only in 6 cases (25%) (chi2 = 6.844; p < 0.01). The OS >/= 5, in the present study, obtained a sensitivity of 60 %, a specificity of 81 %, a positive predictive value of 69 %, and a negative predictive value of 75 %.We concluded that (i) the OS has been useful for identifying depressive symptoms with an acceptable sensitivity and specificity, and (ii) the OS may be an alternative to detect depression in patients who are unable to perform a clinical interview.

Alzheimer's disease (AD) is the most common age-related neurodegenerative disease and an urgent public health problem in many areas of the world. We present the results of the activity of an ad hoc ward, called "Unità di Valutazione Alzheimer " (UVA) (Unit of Evaluation for Alzheimer), along the first two years of the "CRONOS" project (CP). We evaluated the efficacy and safety of acetylcholinesterase inhibitor (AChE-I) agents in the treatment of mild to moderate AD and the population served by the UVA. Three hundred fifty-four patients referred to our ward for cognitive deficits. According to the CP criteria, 66 patients (42 women and 24 men, mean age 74.1 +/- 5.8 years) were enrolled in the study. Evaluation was carried out at baseline and after 3, 9, 15, and 21 months. Our results showed a positive impact of these drugs on patients with mild to moderate AD during the first nine months of treatment. After this period, we observed a progressive lowering of the mini mental state examination (MMSE) scores, with a global impairment of 0.9-1 .0 points per year. The adverse events were generally not troublesome. Our data strongly support the usefulness of UVA in the AD case ascertainment during the early phase of the disease.Moreover, the CP provided a general better knowledge about this important and devastating disease.

In Alois Alzheimer's times, an integrated approach combining neurology, psychiatry and neuropathology was natural, but those directions are growing apart from each other. Although no doubt these fields have developed into new fruitful disciplines, there is the danger of inconsistency and tunnel vision. In this lecture, a plea is made for a more integrative neuropsychiatric approach. This is demonstrated by means of new research findings from the Maastricht Behavior and Dementia Study, and the Maastricht MCI cohort study. A broad neuropsychiatric approach, in which both biological and psychosocial aspects are studied, does greater justice to patients with dementia. A too narrow view of dementia as a cognitive disorder not only frustrates research, but also is not at all helpful to patients and their carers, because the most harrowing aspects of the disease remain underexposed. Research on psychosocial aspects and care should be given a higher priority.

Today home health care (HHC) programs have been developed in numerous Western countries, in order to answer the questions regarding the care of frail elderly suffering from polypathologies and, therefore, being at high risk of disability. The HHC program of the Israelite Hospital of Rome has been planned as a complementary model, and not as a substitute of hospitalization, being able to offer flexible services, suitable for each elderly patient. The present study has established that taking care of old patients in their home allows us to prevent the deterioration of cognitive performance and functional impairments,as measured by the mini mental state examination (MMSE), the scales of activity of daily living (ADL), and the instrumental activity of daily living (IADL), respectively. We found considerable improvements also in the mood disorders during HHC, as measured by the geriatric depression scale (GDS). All psychometric tests were administered at the beginning of home care and after almost 1 year. Moreover, we formulated some questions regarding the quality of the offered services, and the answers revealed great satisfaction of both the patients and their caregivers.

Cognitive impairment, depression and delirium are problems of high prevalence in older patients. The geriatric convalescence unit (GCU) is a hospitalization facility offering an interdisciplinary geriatric intervention program that may be more appropriate for these patients. This study intended to analyze the functional improvement (FI) in older patients with cognitive impairment, depression and/or delirium admitted to a GCU. A group of 107 patients received specific nurse care, habitually performed in GCU and they also were included in a rehabilitation program. Cognitive impairment, depression and delirium were diagnosed according to standardized protocols. The analyzed variables were: age, functional status (Barthel index) before admission (BBA), at admission (BA) and at discharge(BD), diagnostic categories, cognitive function (mini mental state examination: MMSE) and post-discharge destination. The corrected Heinemann index (CHI) was used to evaluate FI obtained during GCU-stay, where CHI = 100 x (BD-BA)/(BBA-BA), and the efficiency index(El) was used to analyze the relationship between FI and the length of stay in the GCU,where El = (BD-BA)/(days in GCU). According to CHI, patients were divided in three groups. Group I: CHI = 0 or negative (patients who lost functional capacity during hospitalization,those who died or were transferred to hospital owing to acute deterioration. Group II: CHI < 35 % (high FI). Mean age was 77.6 +/- 9.1 years, the diagnostic categories were: fractures/orthopedics 49 (45.7 %), neurological 27(25.2 %), pulmonary/cardiologic 6 (5.6 %) and other cases 25 (23.3 %). Mean MMSE and BA scores were 16.9 +/- 9.4 and 29.6 +/- 18.9, respectively. Post-discharge destinations were:63 patients (58.8 %) returned home, 28 (26.1 %) were definitively institutionalized, 11 (10.2%) died and finally 5 (4.6 %) were transferred to acute care hospital. In-Group I, there were 35 patients (32.7 %) with a mean value of the El = 0.12 +/-1.1; in Group II, 13 (12.1 %) and 0.26 +/- 0.38; in Group III, 59 (55.1 %) and 0.94 +/- 0.97, respectively. In spite of the presence of cognitive impairment, depression and/or delirium, a high proportion of patients (67.2 %)obtained a significant improvement in their functional capacity.35 % (moderate FI). Group III: CHI >/=

This study on home care for demented patients is one of the finalized research projects sponsored by the Ministry of Health. The teams involved are: the Home Hospitalization Service (HHS) of S. Giovanni Battista Hospital of Torino, the "Azienda Sanitaria Locale n 20" (ASL 20) of Alessandria and Tortona and the "Presidio Ospedaliero Riabilitativo Fatebenefratelli" of San Maurizio Canavese (Torino). Aim of the study is to assess the feasibility and usefulness of taking care of elderly demented patients at home and to improve the quality of life of patients and their relatives, involving training experiences and economic help. The Geriatric Department of San Giovanni Battista Hospital started a randomized controlled study on 109 severely demented subjects admitted to the emergency room of the hospital. Fifty-three patients were transferred to the traditional geriatric ward and 56 to the HHS. The team of ASL 20 of Alessandria and Tortona selected and evaluated 45 elderly demented patients living at home. These subjects, stratified for their cognitive and functional impairment, were randomly allocated to two different groups: a group receiving an economic help for one year and a control group. In the first setting of research the degree of dementia was severe, mini mental state examination (MMSE) score was 10.0 +/- 5.2 for patients at home, and 10.5 +/- 6 for the second group. The majority of patients followed at home (78.6 %) were discharged, while only 47.2 % of the in-patients returned home (p < 0.001). Seventeen out of 53 patients (32.1 %) admitted to the traditional ward and only two of home-hospitalization patients had to be sent to nursing home (p <0.001). The 45 subjects evaluated by the team of ASL 20 were divided into two groups.Twenty-four subjects were allocated to receive a home care allowance. Their functional status was impaired. Their MMSE score was 12.6 +/- 5.4 and clinical dementia rating scale(CDR) score 2.7 +/- 0.9. A control group of 21 subjects (17 women and 4 men) showed similar characteristics as the previously described group.
