Mental Health among Geriatric Healthcare Workers in Italy during the COVID-19 Pandemic: Results from a National Survey.

OBJECTIVES: This study aimed to investigate the psychological impact of the COVID-19 pandemic on healthcare workers (HCWs) in geriatric settings. DESIGN: Online cross-sectional survey. SETTINGS AND PARTICIPANTS: 394 geriatric HCWs in Italy. MEASUREMENTS: The survey was developed by a multidisciplinary team and disseminated in April 2022 to the members of two geriatric scientific societies (Italian Society of Geriatrics and Gerontology and Italian Association of Psychogeriatrics). The survey examined the experiences related to the COVID-19 pandemic, as well as psychological burden and support. Work-related anxiety and distress related to the pandemic were studied using the SAVE-9 scale (Stress and Anxiety to Viral Epidemics). RESULTS: Three hundred sixty-four participants (92.4%) changed their job activity during the pandemic and about half (50.9%) failed to cope with this change, 58 (14.7%) had increased work-related anxiety, and 39 (9.9%) work-related stress levels. Three hundred forty (86.3%) participants reported acute stress reaction symptoms, including irritability, depressed mood, headache, anxiety, and insomnia, and 262 (66.5%) required psychological support, mainly from friends/relatives (57.9%) and/or colleagues (32.5%). Furthermore, 342 participants (86.8%) recognized they would benefit from informal and formal psychological support in case of future similar emergencies. CONCLUSIONS: This study highlights the high psychological burden experienced by geriatric HCWs in Italy during the COVID-19 pandemic and emphasizes the need for supportive interventions.

Clinical Presentation of COVID19 in Dementia Patients.

OBJECTIVE: No studies analyzing the role of dementia as a risk factor for mortality in patients affected by COVID-19. We assessed the prevalence, clinical presentation and outcomes of dementia among subjects hospitalized for COVID19 infection. DESIGN: Retrospective study. SETTING: COVID wards in Acute Hospital in Brescia province, Northern Italy. PARTICIPANTS: We used data from 627 subjects admitted to Acute Medical wards with COVID 19 pneumonia. MEASUREMENTS: Clinical records of each patients admitted to the hospital with a diagnosis of COVID19 infection were retrospectively analyzed. Diagnosis of dementia, modalities of onset of the COVID-19 infection, symptoms of presentation at the hospital and outcomes were recorded. RESULTS: Dementia was diagnosed in 82 patients (13.1%). The mortality rate was 62.2% (51/82) among patients affected by dementia compared to 26.2% (143/545) in subjects without dementia (p<0.001, Chi-Squared test). In a logistic regression model age, and the diagnosis of dementia resulted independently associated with a higher mortality, and patients diagnosed with dementia presented an OR of 1.84 (95% CI: 1.09-3.13, p<0.05). Among patients diagnosed with dementia the most frequent symptoms of onset were delirium, especially in the hypoactive form, and worsening of the functional status. CONCLUSION: The diagnosis of dementia, especially in the most advanced stages, represents an important risk factor for mortality in COVID-19 patients. The clinical presentation of COVID-19 in subjects with dementia is atypical, reducing early recognition of symptoms and hospitalization.

Italian consensus recommendations for a biomarker-based aetiological diagnosis in mild cognitive impairment patients.

BACKGROUND AND PURPOSE: Biomarkers support the aetiological diagnosis of neurocognitive disorders in vivo. Incomplete evidence is available to drive clinical decisions; available diagnostic algorithms are generic and not very helpful in clinical practice. The aim was to develop a biomarker-based diagnostic algorithm for mild cognitive impairment patients, leveraging on knowledge from recognized national experts. METHODS: With a Delphi procedure, experienced clinicians making variable use of biomarkers in clinical practice and representing five Italian scientific societies (neurology - Società Italiana di Neurologia per le Demenze; neuroradiology - Associazione Italiana di Neuroradiologia; biochemistry - Società Italiana di Biochimica Clinica; psychogeriatrics - Associazione Italiana di Psicogeriatria; nuclear medicine - Associazione Italiana di Medicina Nucleare) defined the theoretical framework, relevant literature, the diagnostic issues to be addressed and the diagnostic algorithm. An N-1 majority defined consensus achievement. RESULTS: The panellists chose the 2011 National Institute on Aging and Alzheimer's Association diagnostic criteria as the reference theoretical framework and defined the algorithm in seven Delphi rounds. The algorithm includes baseline clinical and cognitive assessment, blood examination, and magnetic resonance imaging with exclusionary and inclusionary roles; dopamine transporter single-photon emission computed tomography (if no/unclear parkinsonism) or metaiodobenzylguanidine cardiac scintigraphy for suspected dementia with Lewy bodies with clear parkinsonism (round VII, votes (yes-no-abstained): 3-1-1); 18 F-fluorodeoxyglucose positron emission tomography for suspected frontotemporal lobar degeneration and low diagnostic confidence of Alzheimer's disease (round VII, 4-0-1); cerebrospinal fluid for suspected Alzheimer's disease (round IV, 4-1-0); and amyloid positron emission tomography if cerebrospinal fluid was not possible/accepted (round V, 4-1-0) or inconclusive (round VI, 5-0-0). CONCLUSIONS: These consensus recommendations can guide clinicians in the biomarker-based aetiological diagnosis of mild cognitive impairment, whilst guidelines cannot be defined with evidence-to-decision procedures due to incomplete evidence.

Recognition and management of delirium among doctors, nurses, physiotherapists, and psychologists: an Italian survey.

BACKGROUND: There are no studies that have identified the ability to recognize and manage delirium among Italian health providers caring for patients at risk. Therefore, the Italian Association of Psychogeriatrics (AIP) conducted a multicenter survey among doctors, nurses, psychologists and physiotherapists to assess their competence regarding the theme of delirium and its management in the everyday clinical practice. METHODS: The survey period was 1st June 2013 to 30th November 2013. The invitation to participate was sent via email, with publication on the AIP website. The survey included 14 questions and two case vignettes. RESULTS: A total of 648/1,500 responses were collected. Most responders were doctors (n = 322/800), followed by nurses (n = 225/500), psychologists (n = 51/100), and physiotherapists (n = 30/100). Generally, doctors and psychologists correctly defined delirium, while nurses and physiotherapists did not. The most frequently used diagnostic tools were the Confusion Assessment Method (CAM) and the Diagnostic and Statistical Manual of Mental Disorders-IV. Delirium intensity was rarely assessed. Hypoactive delirium was generally managed with non-pharmacological approaches, while hyperactive delirium with a combination of non-pharmacological and pharmacological approaches. However, possible causes of delirium were under-assessed by half of doctors and by the majority of other professionals. Nurses, psychologists and physiotherapists did not answer the case vignettes, while doctors identified the correct answer in most cases. CONCLUSIONS: This is the first Italian survey among health providers caring for patients at risk of delirium. This is also the first survey including doctors, nurses, psychologists and physiotherapists. The results emphasize the importance of training to improve knowledge of this relevant unmet medical need.

The management of hip fracture in the older population. Joint position statement by Gruppo Italiano Ortogeriatria (GIOG).

This document is a Joint Position Statement by Gruppo Italiano di OrtoGeriatria (GIOG) supported by Società Italiana di Gerontologia e Geriatria (SIGG), and Associazione Italiana Psicogeriatria (AIP) on management of hip fracture older patients. Orthogeriatric care is at present the best model of care to improve results in older patients after hip fracture. The implementation of orthogeriatric model of care, based on the collaboration between orthopaedic surgeons and geriatricians, must take into account the local availability of resources and facilities and should be integrated into the local context. At the same time the programme must be based on the best available evidences and planned following accepted quality standards that ensure the efficacy of the intervention. The position paper focused on eight quality standards for the management of hip fracture older patients in orthogeriatric model of care. The GIOG promotes the development of a clinic database with the aim of obtaining a qualitative improvement in the management of hip fracture.

Consensus and variations in opinions on delirium care: a survey of European delirium specialists.

BACKGROUND: There are still substantial uncertainties over best practice in delirium care. The European Delirium Association (EDA) conducted a survey of its members and other interested parties on various aspects of delirium care. METHODS: The invitation to participate in the online survey was distributed among the EDA membership. The survey covered assessment, treatment of hyperactive and hypoactive delirium, and organizational management. RESULTS: A total of 200 responses were collected (United Kingdom 28.6%, Netherlands 25.3%, Italy 15%, Switzerland 9.7%, Germany 7.1%, Spain 3.8%, Portugal 2.5%, Ireland 2.5%, Sweden 0.6%, Denmark 0.6%, Austria 0.6%, and others 3.2%). Most of the responders were doctors (80%), working in geriatrics (45%) or internal medicine (14%). Ninety-two per cent of the responders assessed patients for delirium daily. The most commonly used assessment tools were the Confusion Assessment Method (52%) and the Delirium Observation Screening Scale (30%). The first-line choice in the management of hyperactive delirium was a combination of non-pharmacological and pharmacological approaches (61%). Conversely, non-pharmacological management was the first-line choice in hypoactive delirium (67%). Delirium awareness (34%), knowledge (33%), and lack of education (13%) were the most commonly reported barriers to improving the detection of delirium. Interestingly, 63% of the responders referred patients after an episode of delirium to a follow-up clinic. CONCLUSIONS: This is the first systematic survey involving an international group of specialists in delirium. Several areas of lack of consensus were found. These results emphasise the importance of further research to improve care of this major unmet medical need.

Subthreshold depression in older subjects: an unmet therapeutic need.

Major depression, defined according to DSM IV TR criteria, is less common in older subjects, while other types of depression are two to three times more prevalent. This heterogeneous group of disturbances has received different names: depression not otherwise specified, minor depression, subthreshold or subsyndromal depression. Moreover, each condition has been defined using heterogeneous criteria by different authors. The term of subthreshold depression will be adopted in this position statement. Subthreshold depression has been associated with the same negative consequences of major depression, including reduced well being and quality of life, worsening health status, greater disability, increased morbidity and mortality. Nevertheless, there is a dearth of clinical trials in this area, and therefore older patients with subthreshold depression are either not treated or they are treated with the same non pharmacological and pharmacological therapies used for major depression, despite the lack of supporting scientific evidence. There is an urgent need to reach a consensus concerning the diagnostic criteria for subthreshold depression as well as to perform clinical trials to identify effective and safe therapies in this too long neglected patient group.

Understanding terminology of delirium and long-term cognitive impairment in critically ill patients.

Delirium, an acute brain dysfunction, frequently affects intensive care unit (ICU) patients during the course of a critical illness. Besides the acute morbidities, ICU survivors often experience long-term sequelae in the form of cognitive impairment (LTCI-CI). Though delirium and LTCI-CI are associated with adverse outcomes, little is known on the terminology used to define these acute and chronic co-morbidities. The use of a correct terminology is a key factor to spread the knowledge on clinical conditions. Therefore, we first review the epidemiology, definition of delirium and its related terminology. Second, we report on the epidemiology of LTCI-CI and compare its definition to other forms of cognitive impairments. In particular, we define mild cognitive impairment, dementia and finally postoperative cognitive dysfunction. Future research is needed to interpret the trajectories of LTCI-CI, to differentiate it from neurodegenerative diseases and to provide a formal disease classification.

Music, music therapy and dementia: a review of literature and the recommendations of the Italian Psychogeriatric Association.

This study reviews the most recent (from 2000 to 2011) Clinical Controlled Trials (CCT) and Randomized Controlled Trials (RCT) concerning the use of music and music-therapy (MT) in the context of dementia and related issues. Studies which explored the efficacy of music and MT on behavioral and psychological symptoms of dementia (BPSD) are prevalent, while those aiming at assessing a potential effect of these approaches on cognitive and physiological aspects are scant. Although with some limitations, the results of these studies are consistent with the efficacy of MT approach on BPSD. In this context, the ability of the music therapist to directly interact with the patients appears to be crucial for the success of the intervention. This review was endorsed by the Italian Psychogeriatric Association (AIP) and represents its view about the criteria to select appropriate music and MT approaches in the field of dementia. Accordingly, we have developed a list of recommendations to facilitate the current use of these techniques in the context of non-pharmacological treatments for patients with dementia.

Addendum to 'Efficacy of music therapy treatment based on cycles of sessions: a randomised controlled trial' (Raglio et al., 2010).

OBJECTIVES: The aim of this paper is to provide further detail about the results of a randomised controlled study published in this journal (Raglio et al., 2010, 14, 900-904), in which we assessed the efficacy of music therapy (MT) on the behavioural disturbances in people with moderate-severe dementia. METHODS: Sixty patients were randomly assigned to the experimental (MT and standard care) and control group (standard care only). The experimental group received three cycles of 12 MT sessions each, three times a week. Each cycle of treatment was followed by one month of washout period, while the standard care activities continued over time. RESULTS: The impact of the treatment (12 MT sessions) was reliable on NPI global scores, as the interaction Time by Group was significant (F(1,49) = 4.09, p = 0.049). After the end of the treatment the NPI global scores of the experimental and control groups tended to become similar, as both groups worsened (Time effect: F(1,48) = 4.67, p = 0.014) and the difference between them disappeared (F < 1). Interaction Time by Group was not significant. CONCLUSIONS: The study confirms that active MT determines a positive response and can amplify and strengthen the efficacy of therapeutic interventions towards people with dementia.

A prognostic model predicting recovery of walking independence of elderly patients after hip-fracture surgery. An experiment in a rehabilitation unit in Northern Italy.

UNLABELLED: A score for identifying post-hip-fracture surgery patients at various levels (high, medium, and low) of risk for unsuccessful recovery of pre-fracture walking ability was developed. Three hundred ninety-eight HF patients were enrolled in the study. The score significantly and independently predicted failure to walk independently at discharge, failure to walk independently after 12 months, and death after 12 months. The score may be useful for clinicians and healthcare administrators to target populations for rehabilitative programs. INTRODUCTION: To develop a model predicting at the time that elderly hip-fracture (HF) patients undergo rehabilitation if they will have recovered walking independence at discharge. METHODS: Data from all patients admitted to a Department of Rehabilitation in Italy between January 2001 and June 2008 after HF surgery were used. Variables concerning cognitive, clinical, functional, and social parameters were evaluated. Predominant measures were identified through correspondence analysis, and a variable score was defined. Three risk classes (minimum, moderate, and high) were identified and univariate and multivariate logistic regressions were used to assess the model's predictivity and risk classes for the various outcomes. RESULTS: Three hundred ninety-eight HF patients were enrolled. The variables selected to construct the score were age, gender, body mass index, number of drugs being taken, the Mini Mental State Examination, the Instrumental Activity of Daily Living, and the pre-fracture Barthel index. According to univariate analysis, the score was not better than the pre-fracture Barthel's index, but, according to multivariate analysis, it was an independent predictor for all the outcomes, while the pre-fracture Barthel index predicted only outcomes at discharge. In particular, the score significantly predicted failure to walk independently at discharge, failure to walk independently after 12 months, and death after 12 months. CONCLUSIONS: A method of identifying post-HF surgery patients at various levels (high-, medium-, and low-) of risk for unsuccessful recovery of pre-fracture walking ability has been designed. The method may be useful for clinicians and healthcare administrators to target populations for rehabilitative programs.

PI3K/AKT signaling determines a dynamic switch between distinct KSRP functions favoring skeletal myogenesis.

Skeletal myogenesis is orchestrated by distinct regulatory signaling pathways, including PI3K/AKT, that ultimately control muscle gene expression. Recently discovered myogenic micro-RNAs (miRNAs) are deeply implicated in muscle biology. Processing of miRNAs from their primary transcripts is emerging as a major step in the control of miRNA levels and might be well suited to be regulated by extracellular signals. Here we report that the RNA binding protein KSRP is required for the correct processing of primary myogenic miRNAs upon PI3K/AKT activation in myoblasts C2C12 and in the course of injury-induced muscle regeneration, as revealed by Ksrp knock-out mice analysis. PI3K/AKT activation regulates in opposite ways two distinct KSRP functions inhibiting its ability to promote decay of myogenin mRNA and activating its ability to favor maturation of myogenic miRNAs. This dynamic regulatory switch eventually contributes to the activation of the myogenic program.

Efficacy of music therapy treatment based on cycles of sessions: a randomised controlled trial.

We undertook a randomised controlled trial to assess whether a music therapy (MT) scheme of administration, including three working cycles of one month spaced out by one month of no treatment, is effective to reduce behavioural disturbances in severely demented patients. Sixty persons with severe dementia (30 in the experimental and 30 in the control group) were enrolled. Baseline multidimensional assessment included demographics, Mini Mental State Examination (MMSE), Barthel Index and Neuropsychiatry Inventory (NPI) for all patients. All the patients of the experimental and control groups received standard care (educational and entertainment activities). In addition, the experimental group received three cycles of 12 active MT sessions each, three times a week. Each 30-min session included a group of three patients. Every cycle of treatment was followed by one month of wash-out. At the end of this study, MT treatment resulted to be more effective than standard care to reduce behavioural disorders. We observed a significant reduction over time in the NPI global scores in both groups (F(7,357) = 9.06, p < 0.001) and a significant difference between groups (F(1,51) = 4.84, p < 0.05) due to a higher reduction of behavioural disturbances in the experimental group at the end of the treatment (Cohen's d = 0.63). The analysis of single NPI items shows that delusions, agitation and apathy significantly improved in the experimental, but not in the control group. This study suggests the effectiveness of MT approach with working cycles in reducing behavioural disorders of severely demented patients.

Akt2-mediated phosphorylation of Pitx2 controls Ccnd1 mRNA decay during muscle cell differentiation.

Paired-like homeodomain 2 (Pitx2), first identified as the gene responsible for the Axenfeld-Rieger syndrome, encodes a protein factor that, controlling cell proliferation in a tissue-specific manner, has a crucial role in morphogenesis. During embryonic development, Pitx2 exerts a role in the expansion of muscle progenitors and is expressed at all stages of myogenic progression. In this study, we show that Pitx2 is phosphorylated by the protein kinase Akt2 and is necessary to ensure proper C2C12 myoblast proliferation and differentiation. Pitx2 associates with a ribonucleoprotein complex that includes the mRNA stabilizing factor HuR and sustains Ccnd1 (also known as Cyclin D1) expression, thereby prolonging its mRNA half-life. When the differentiation program is initiated, phosphorylation by Akt2 impairs the ability of Pitx2 to associate with the Ccnd1 mRNA-stabilizing complex that includes HuR and, as a consequence, Ccnd1 mRNA half-life is shortened. We propose that unphosphorylated Pitx2 is required to favor HuR-mediated Ccnd1 mRNA stabilization, thus sustaining myoblast proliferation. Upon Akt2-phosphorylation, the complex Pitx2/HuR/Ccnd1 mRNA dissociates and Ccnd1 mRNA is destabilized. These events contribute to the switch of C2C12 cells from a proliferating to a differentiating phenotype.

Advances in sedation for critically ill patients.

The use of sedation is required for the majority of mechanically ventilated patients in order to ensure comfort. For many years, deep sedation was the standard of care to avoid unpleasant memories and anxiety and provide comfort. Research over the past decade has shown the importance of using different tools to assess the level of sedation in order to guide appropriate dosing of sedatives and to measure the clinical response to sedation. Given the progress in recent trials in this area, the management of sedation in the Intensive Care Unit (ICU) can be improved using various approaches that have shown improved outcomes in the ICU. The most prominent of these interventions involves linking daily interruptions in sedation (i.e. spontaneous awakening trials, SATs) with ventilator weaning protocols that incorporate spontaneous breathing trials (SBTs). Intensivists should combine the goals of ensuring patient comfort and avoiding unpleasant memories with other important goals that can be achieved with these new strategies (i.e. SATs plus SBTs or the so-called ''wake up and breathe approach''), such as a three day reduction in time spent on the ventilator, a four day reduction in ICU and hospital stays and a 14% absolute reduction in death at one year. New choices for sedation, such as alpha-2 agonists and ultra short narcotics, are also being actively investigated, which may lead to complementary improvements in the future management of these critically ill, vulnerable patients.

Understanding international differences in terminology for delirium and other types of acute brain dysfunction in critically ill patients.

BACKGROUND: Delirium (acute brain dysfunction) is a potentially life threatening disturbance in brain function that frequently occurs in critically ill patients. While this area of brain dysfunction in critical care is rapidly advancing, striking limitations in use of terminology related to delirium internationally are hindering cross-talk and collaborative research. In the English literature, synonyms of delirium such as the Intensive Care Unit syndrome, acute brain dysfunction, acute brain failure, psychosis, confusion, and encephalopathy are widely used. This often leads to scientific "confusion" regarding published data and methodology within studies, which is further exacerbated by organizational, cultural and language barriers. OBJECTIVE: We undertook this multinational effort to identify conflicts in terminology and phenomenology of delirium to facilitate communication across medical disciplines and languages. METHODS: The evaluation of the terminology used for acute brain dysfunction was determined conducting communications with 24 authors from academic communities throughout countries/regions that speak the 13 variants of the Romanic languages included into this manuscript. RESULTS: In the 13 languages utilizing Romanic characters, included in this report, we identified the following terms used to define major types of acute brain dysfunction: coma, delirium, delirio, delirium tremens, délire, confusion mentale, delir, delier, Durchgangs-Syndrom, acute verwardheid, intensiv-psykose, IVA-psykos, IVA-syndrom, akutt konfusion/forvirring. Interestingly two terms are very consistent: 100 % of the selected languages use the term coma or koma to describe patients unresponsive to verbal and/or physical stimuli, and 100% use delirium tremens to define delirium due to alcohol withdrawal. Conversely, only 54% use the term delirium to indicate the disorder as defined by the DSM-IV as an acute change in mental status, inattention, disorganized thinking and altered level of consciousness. CONCLUSIONS: Attempts towards standardization in terminology, or at least awareness of differences across languages and specialties, will help cross-talk among clinicians and researchers.

Neuropsychiatric symptoms in amnestic and nonamnestic mild cognitive impairment.

BACKGROUND: The information regarding neuropsychiatric symptoms in the subtypes of mild cognitive impairment (MCI) is inadequate. OBJECTIVE: To describe the behavioral neuropsychiatric symptoms of MCI in two subgroups of MCI patients with different neuropsychological characteristics. METHODS: MCI patients are classified as amnestic (aMCI) if they have a prominent memory impairment, either alone or with other cognitive impairments (multiple domains with amnesia), or nonamnestic (naMCI) if a single nonmemory domain is impaired alone or in combination with other nonmemory deficits (multiple domains without amnesia). The Neuropsychiatric Inventory (NPI) was administrated to detect behavioral and psychological disturbances observed by the caregiver. RESULTS: 120 subjects were analyzed: 94 were classified as aMCI and 26 as naMCI. Subjects with aMCI were more compromised than those with naMCI on global cognitive functions. About 85% of MCI patients had some neuropsychiatric symptoms evaluated with the NPI and the most prevalent symptom was depression, followed by anxiety. A significantly higher prevalence of hallucinations and sleep disorders has been observed in the naMCI group in comparison with the aMCI group. CONCLUSION: Neuropsychiatric symptoms occur in the majority of persons with MCI and may be the earliest manifestation of different diseases, each one associated with different clinical profiles at the stage of MCI.

Personality changes in Alzheimer's disease.

BACKGROUND: Assessment of personality changes in patients with dementia has received little systematic investigation, although caregivers report personality modifications in every phase of dementia. METHODS: A group of 52 patients with probable Alzheimer's disease (AD) vs. a group of fifteen control subjects were selected for these personality tests before and after the manifestation of dementia using an Italian version of Brooks and McKinaly's Personality Inventory (PI). RESULTS: After the onset of AD, a significant shift from positive to negative characteristics in PI was observed in 12 of 18 bipolar pairs of adjectives constituting the instrument and the total mean PI score decreased significantly (p < 0.001), indicating a substantial worsening of personality profile. In the control group however, evaluated before and after retirement, personality traits and total mean PI score did not show a significant change. The association of personality traits and total PI score with demographic, cognitive and functional characteristics of AD patients was calculated. CONCLUSION: Personality changes have been depicted to be influenced by severity of cognitive, functional and behavioural complaints rather than age, sex, education and disease duration. These first applications of the Italian version of PI confirmed that personality modifications make a consistent aspect of the phenomenology of AD although in the negative direction. Further studies are needed to understand the nature of personality changes in dementia and the utility of PI to investigate these changes.

Effectiveness of a cognitive rehabilitation program in mild dementia (MD) and mild cognitive impairment (MCI): a case control study.

Data support the evidence that neuropsychological rehabilitation is effective in Alzheimer disease (AD), to strengthen the pharmacological treatment to delay the progression of dementia. At moment, a few studies have examined the efficacy of non-pharmacological treatment in MCI. This is a controlled study that assesses the effectiveness of neuropsychological rehabilitation on cognitive and behavioral symptoms and functional status in a group of community-dwelling subjects with MCI and MD. Our results demonstrate that a systematic rehabilitation, that provides a computerized cognitive program training, produces an improvement in cognitive and affective status of patients with MCI and MD, while a rehabilitation program not providing a punctual stimulation of cognitive functions, does not have significant effects.
