RESUMO

Given the potential use of biomarkers in the diagnosis of Alzheimer's disease (AD) in early stages, new ethical and communication dilemmas appear in everyday clinical practice. The aim of this study was to know the opinion of health professionals (HP) and general public (GP) on the implementation of early diagnostic techniques in AD and the use of biomarkers for this purpose. A survey with multiple choice answers was elaborated in two versions: one for HP and the other for GP. Respondents were invited to participate through a system of mass mailing e-mail; e-mail addresses were collected from CEMIC database. A total of 1503 answers were analyzed: 807 HP and 696 GP. Most respondents, 84.7%, preferred the option of early diagnosis of AD even knowing the lack of curative treatment. Forty five percent of GP and 26.8% of HP replied that there is no ethical dilemma in the use of biomarkers and that no communication or ethical dilemma is generated to physicians when informing the diagnosis of the disease. The HP group showed more divergence in the views than the GP group. These results may indicate a change in the physician-patient relationship, showing the GP group with an active and supportive position towards the use of biomarkers for early diagnosis of AD.

RESUMO

Population aging has increased age-related diseases such as dementia, Alzheimer's disease (AD) being the most common in older adults (50%-60%). It is one of the most feared conditions for its irreversible and incurable, by its chronicity and it consists of a long process of depersonalization. The clinical diagnosis is mainly based on DSM-IV and NINCDS-ADRDA. Definitive diagnosis is post-mortem, as it requires histopathological confirmation. However, there have been new diagnostic criteria based EA biomarkers, which can be done in life, anticipating the course of several years before dementia. Thus, physicians are increasingly exposed to AD patients in early stages, having to face the dilemma of communicating the diagnosis to a patient with cognitive failures and disease awareness, with the implications that generates about him and his family. The objectives of this paper will analyze the ethical problem of communication of clinical diagnosis of AD in prodromal stages (pre-dementia) in our country, based on the analysis of ethical principles (autonomy and non maleficence) involved in decision making.

RESUMO

BACKGROUND: Mild cognitive impairment (MCI) is a transitional state between normal aging and dementia. Identifying this condition would allow early interventions that may reduce the rate of progression to Alzheimer's disease (AD). We examined the efficacy of a six-month cognitive intervention program (CIP) in patients with MCI and to assess patients' condition at one-year follow-up. METHODS: Forty-six MCI participants assessed with neuropsychological, neurological, neuropsychiatry, and functional procedures were included in this study and followed up during a year. The sample was randomized into two subgroups: 24 participants (the "trained group") underwent the CIP during six months while 22 (control group) received no treatment. Sixteen participants dropped out of the study. The intervention focused on teaching cognitive strategies, cognitive training, and use of external aids, in sessions of two hours, twice per week for six months. Cognitive and functional measures were used as primary outcome and all were followed up at one year. RESULTS: The intervention effect (mean change from baseline) was significant (p < 0.05) on the Mini-Mental State Examination (1.74), the Clinical Dementia Rating Scale (0.14), the Boston Naming Test (2.92), block design (-13.66), matrix reasoning (-3.07), and semantic fluency (-3.071) tasks. Four patients (one trained and three controls) progressed to dementia after one year of follow-up. CONCLUSIONS: These results suggest that persons with MCI can improve their performance on cognitive and functional measures when provided with early cognitive training and it could persist in a long-term follow-up.

RESUMO

UNLABELLED: Mild cognitive impairment (MCI) has 3 clinical subtypes: amnestic (aMCI), multiple domains (mdMCI) and non-amnestic single domain (na-SD-MCI) whose evolutive possibility to dementia has not been profoundly studied. OBJECTIVE: This paper aims to determine the conversion to dementia of the different subtypes of MCI and determine risk factors associated to conversion to dementia. METHODS: A total of 127 patients diagnosed with MCI (age=70.21; SD=13.17) were evaluated with a neuropsychological and neuropsychiatric battery. They were classified into 3 groups: amnestic MCI (n=20), multiple-domain MCI (n=98), non-amnestic MCI (n=9). Seventeen normal subjects (age=74.59; SD=10.63) were included. RESULTS: Of those included, 27.1% developed Alzheimer's type dementia [average time for conversion to Alzheimer's dementia (AD) 11.12 months (SD=0.183)]. None of the controls developed dementia. Thirty-five percent (n=7) of amnestic MCI converted to AD: 20% (n=4) at 6 months and 15% (n=3) at 12 months); 11.1% (n=1) of the non-amnestic single domain MCI converted to AD at 6 months. It was found that 31.6% (n=31) of multiple domain MCI rotated to AD: 15.3% (n=15) at 6 months and 16.3% (n=16) at 12 months. Age (p<0.05, ß=1.03) increased the likelihood of rotation to AD. Multi-domain MCI subtype was the most frequent. However, the conversion to dementia in amnestic subtype was the highest, age and retirement being the variables that increased the likelihood of conversion to Dementia.

RESUMO

Since 1 January 2020, the Central Research Ethics Committee of the Health Ministry implemented PRIISA.BA, an in-house developed electronic system for online submission of health research applications to the 63 public and private research ethics committees (RECs) of Buenos Aires City, Argentina. This study though to compare the times to first review and the time to approval among applications submitted prior to PRIISA.BA and thereafter, across public RECs. All public RECs of the city were invited to participate. Overall, 453 applications from 10 RECs (242 pre- and 211 post-PRIISA.BA) were available for the analyses. There was a decrease in the time to first review and an increase in the time to approval after PRIISA.BA implementation. The increase in time to approval was transient and limited to the first three months. The results were consistent with analyses limited to non-COVID applications. Our results show an increase in the times to approval after the implementation of an electronic system for online submission of health research applications that, although transient, was significant. These data could be relevant to other RECs implementing this technology since it emphasizes the need of monitoring potential unnecessary delays in reviews during the critical initial period.

RESUMO

Subjective cognitive decline (SCD), which precedes Mild Cognitive Impairment and dementia, may be affected by purpose in life (PiL) and loneliness in older adults. We investigated associations among PiL, loneliness, and SCD in US Latino (n = 126), Black (n = 74), Asian (n = 33), and White (n = 637) adults. Higher PiL predicted lower SCD in all groups (p-values < .012), except Black participants. Lower loneliness predicted lower SCD in Latino and White groups (p-values < .05), and PiL moderated this association in White adults. PiL and loneliness may play important roles in cognitive decline. Differential predictors of SCD suggest differential targets for preventing cognitive decline and dementia across ethnoracial groups.

RESUMO

The symptomatic predementia phase of Alzheimer's disease (AD), known as mild cognitive impairment (MCI) is a clinical and neuropsychological condition which defines the transitional state between normal aging and dementia, and is used as a clinical description of people at risk of developing AD. A review of the diagnostic criteria of MCI due to Alzheimer's disease was recently published by the Alzheimer's Association and the National Institute on Aging of the U.S. in order to ensure early diagnosis of the disease, useful for both clinical practice and clinical trials. The objectives of this paper are to review and analyze the revised diagnostic criteria for MCI due to Alzheimer's disease recently proposed, to compare with criteria for MCI available and to establish current strengths and limitations of the new proposal in clinical practice. The new diagnostic criteria for MCI due to AD have a radical importance since they are potentially applicable in the clinical or research protocols and in all clinical settings where such markers are available. They provide a useful, consistent and valuable tool to homogenize the subgroup of patients with MCI who already has AD in a predementia phase with inexorable progression to dementia by AD over the years.

RESUMO

BACKGROUND: The economic cost of dementia is high and can be predicted by cognitive and neuropsychiatric profiles. The differential costs of the various subtypes of dementia are unknown in Argentina, and this study therefore aimed to compare these costs. METHODS: Patients with a diagnosis of dementia of Alzheimer-type (DAT), frontotemporal dementia (FTD) and vascular dementia (VaD), and their primary caregivers, were evaluated between 2002 and 2008. RESULTS: 104 patients with dementia (DAT = 44, FTD = 34, VaD = 26) were screened and matched by age and educational level with 29 healthy subjects. Demographic variables showed no significant differences among dementia patients. The annual direct costs were US$4625 for DAT, US$4924 for FTD, and US$5112 for VaD (p > 0.05 between groups). In the post hoc analysis VaD showed higher hospitalization costs than DAT (p < 0.001). VaD exhibited lower medication costs than FTD (p < 0.001). DAT exhibited higher anti-dementia drug costs; FTD had higher psychotropic costs. In the multivariate analysis, depression, activities of daily living, and caregiver burden were correlated with direct costs (r2 = 0.76). CONCLUSIONS: The different dementia types have different costs. Overall, costs increased with the presence of behavioral symptoms, depression and functional impairment of activities of daily living.

RESUMO

BACKGROUND: People with dementia and their family caregivers may face a great burden through social isolation due to the COVID-19 pandemic, which can be manifested as various behavioral and clinical symptoms. OBJECTIVE: To investigate the impacts of social isolation due to the COVID-19 pandemic on individuals with dementia and their family caregivers. METHODS: Two semi-structured questionnaires were applied via telephone to family caregivers of people diagnosed with dementia in three cities in Argentina, Brazil, and Chile, in order to assess clinical and behavioral changes in people with dementia and in their caregivers. RESULTS: In general, 321 interviews were conducted. A significant decline in memory function has been reported among 53.0%of people with dementia. In addition, 31.2%of individuals with dementia felt sadder and 37.4%had increased anxiety symptoms. These symptoms of anxiety were greater in individuals with mild to moderate dementia, while symptoms of agitation were greater in individuals with severe dementia. Moreover, compulsive-obsessive behavior, hallucinations, increased forgetfulness, altered appetite, and increased difficulty in activities of daily living were reported more frequently among individuals with moderate to severe dementia. Caregivers reported feeling more tired and overwhelmed during this period and these symptoms were also influenced by the severity of dementia. CONCLUSION: Social isolation during the COVID-19 pandemic triggered a series of negative behavioral repercussions, both for people with dementia and for their family caregivers in these three South American countries.

RESUMO

BACKGROUND: In the COVID-19 pandemic, older adults from vulnerable ethnoracial groups are at high risk of infection, hospitalization, and death. We aimed to explore the pandemic's impact on the well-being and cognition of older adults living in the United States (US), Argentina, Chile, Mexico, and Peru. METHODS: 1,608 (646 White, 852 Latino, 77 Black, 33 Asian; 72% female) individuals from the US and four Latin American countries aged ≥ 55 years completed an online survey regarding well-being and cognition during the pandemic between May and September 2020. Outcome variables (pandemic impact, discrimination, loneliness, purpose of life, subjective cognitive concerns) were compared across four US ethnoracial groups and older adults living in Argentina, Chile, Mexico, and Peru. FINDINGS: Mean age for all participants was 66.7 (SD = 7.7) years and mean education was 15.4 (SD = 2.7) years. Compared to Whites, Latinos living in the US reported greater economic impact (p < .001, ηp 2  = 0.031); while Blacks reported experiencing discrimination more often (p < .001, ηp 2  = 0.050). Blacks and Latinos reported more positive coping (p < .001, ηp 2  = 0.040). Compared to Latinos living in the US, Latinos in Chile, Mexico, and Peru reported greater pandemic impact, Latinos in Mexico and Peru reported more positive coping, Latinos in Argentina, Mexico, and Peru had greater economic impact, and Latinos in Argentina, Chile, and Peru reported less discrimination. INTERPRETATION: The COVID-19 pandemic has differentially impacted the well-being of older ethnically diverse individuals in the US and Latin America. Future studies should examine how mediators like income and coping skills modify the pandemic's impact. FUNDING: Massachusetts General Hospital Department of Psychiatry.

RESUMO

The MoCA is a brief useful test to diagnose mild cognitive impairment (MCI) and mild dementia (MD). To date, no Argentine cross-cultural adapted validations of the Spanish version have been reported. OBJECTIVE: To validate the MoCA in the elderly and study its usefulness in MCI and MD. METHODS: This study included 399 individuals over 60 years old evaluated in the Cognitive-Behavioral Department (2017-2018). Patients with<3 years of education, sensory disturbances, psychiatric disorders, or moderate-severe dementia were excluded. The control group comprised cognitively normal subjects. Participants were classified according to neuropsychological assessment and clinical standard criteria into Control, MCI or MD groups. A locally adapted MoCA (MOCA-A) was administered to the patients and controls. RESULTS: Mean educational level was 10.34 years (SD 3.5 years). MoCA-A score differed significantly among groups (p<0.0001). MoCA-A performance correlated with educational level (r: 0.406 p<0.00001). Adopting a cut-off score ≥25 (YI=0.55), the sensitivity for MCI was 84.8% and for MD ​​100%, with specificity of 69.7%. When adding a single point to the score in patients with ≤12 years of education, the specificity of the test reached 81%. CONCLUSION: The MoCA-A is an accurate reliable screening test for MCI and MD in Argentina.


O MoCA é um teste breve e útil para diagnosticar comprometimento cognitivo leve (CCL) e demência leve. Até o momento, nenhuma validação argentina com adaptação transcultural da versão em espanhol havia sido relatada. OBJETIVO: Validar o MoCA em idosos e estudar sua utilidade no CCL e demência leve. MÉTODOS: Este estudo incluiu 399 indivíduos acima de 60 anos avaliados no departamento cognitivo-comportamental (2017-2018). Foram excluídos pacientes com menos de 3 anos de escolaridade, com distúrbios sensoriais, distúrbios psiquiátricos e demência moderada a grave. O grupo controle foi cognitivamente normal. Eles foram classificados de acordo com a avaliação neuropsicológica e os critérios clínicos padrão em Controles, MCI e demência leve. A versão adaptada do MoCA (MOCA-A) foi administrado aos pacientes e controles. RESULTADOS: Média de escolaridade: 10,34 anos (DP: 3,5). O escore MoCA-A foi significativamente diferente entre os grupos (p<0,0001). O MoCA-A correlacionou-se com a escolaridade (r=0,406 p<0,00001). Com uma pontuação de corte ≥25 (IY=0,55), a sensibilidade para CCL foi de 84,8% e para demência leve 100%, com especificidade de 69,7%. Adicionando um ponto único à pontuação em pacientes com menos de 12 anos de escolaridade, a especificidade do teste atingiu 81%. CONCLUSÃO: O MoCA-A é um teste de rastreamento preciso e confiável para MCI e demência leve na Argentina.

RESUMO

INTRODUCTION: Expert knowledge is critical to fight dementia in inequitable regions like Latin American and Caribbean countries (LACs). However, the opinions of aging experts on public policies' accessibility and transmission, stigma, diagnostic manuals, data-sharing platforms, and use of behavioral insights (BIs) are not well known. METHODS: We investigated opinions among health professionals working on aging in LACs (N = 3365) with regression models including expertise-related information (public policies, BI), individual differences (work, age, academic degree), and location. RESULTS: Experts specified low public policy knowledge (X2  = 41.27, P < .001), high levels of stigma (X2  = 2636.37, P < .001), almost absent BI knowledge (X2  = 56.58, P < .001), and needs for regional diagnostic manuals (X2  = 2893.63, df = 3, P < .001) and data-sharing platforms (X2 = 1267.5, df = 3, P < .001). Lack of dementia knowledge was modulated by different factors. An implemented BI-based treatment for a proposed prevention program improved perception across experts. DISCUSSION: Our findings help to prioritize future potential actions of governmental agencies and non-governmental organizations (NGOs) to improve LACs' dementia knowledge.

RESUMO

The SARS-CoV-2 global pandemic will disproportionately impact countries with weak economies and vulnerable populations including people with dementia. Latin American and Caribbean countries (LACs) are burdened with unstable economic development, fragile health systems, massive economic disparities, and a high prevalence of dementia. Here, we underscore the selective impact of SARS-CoV-2 on dementia among LACs, the specific strain on health systems devoted to dementia, and the subsequent effect of increasing inequalities among those with dementia in the region. Implementation of best practices for mitigation and containment faces particularly steep challenges in LACs. Based upon our consideration of these issues, we urgently call for a coordinated action plan, including the development of inexpensive mass testing and multilevel regional coordination for dementia care and related actions. Brain health diplomacy should lead to a shared and escalated response across the region, coordinating leadership, and triangulation between governments and international multilateral networks.

RESUMO

BACKGROUND: Being a caregiver of a patient with Alzheimer's disease is associated with impaired health status and declines in health-related quality of life (HRQoL). This paper evaluates the reliability and validity of the Argentinean version of the Medical Outcomes Study Short-Form Health Survey (SF-36) among caregivers of patients with Alzheimer's disease. METHODS: Forty-eight caregivers of Alzheimer's disease patients completed the SF-36, the Zarit Burden Interview (ZBI) and the Neuropsychiatric Inventory (NPI). Patients were evaluated for dementia severity using the Clinical Dementia Rating (CDR) and for cognitive status using the Mini Mental State Examination (MMSE). RESULTS: The SF-36 scales demonstrated adequate-to-strong internal consistency (Cronbach's alpha range: 0.72 to 0.92). Correlations between the SF-36 scales and the ZBI were moderate to strong (range: -0.19 to -0.79, all p < 0.01 expect for physical function). Significant correlations between the SF-36 scales and the CDR, MMSE and NPI were lower (range: -0.30 to -0.40, p < 0.001) and strongest in mental health-related scales of the SF-36. The SF-36 demonstrated good factorial validity. CONCLUSIONS: The Argentinean translation of the SF-36 is reliable and valid for use to measure the HRQoL of caregivers of patients with Alzheimer's disease.

RESUMO

OBJECTIVE: To examine behavioral, cognitive and functional factors associated with psychosocial burden in caregivers of geriatric patients. METHODS: Primary caregivers assessed were included if the geriatric patient cared for had a cognitive impairment or dementia (degenerative, vascular or mixed) (Group 1) or depression and cerebrovascular disease (CVD) (Group 2). Caregivers completed the Zarit questionnaire, the Neuropsychiatric Inventory (NPI) and Instrumental Activities of Daily Living (IADL). Patients were evaluated for dementia severity using the Clinical Dementia Rating (CDR), Mini Mental State Examination (MMSE) and Beck Depression Inventory (BDI). Structural equation modelling (SEM) was used to assess measurement models and the factors associated with burden. RESULTS: Two hundred and fifty-eight caregiver-patient pairs were included. The best model fit was obtained with a model with two constructs: function-cognition (CDR, MMSE, and IADL) and behavior (neuropsychiatric symptoms from the NPI). In Group 1, both function (B = 0.32. T = 2.79) and behavior (B = 0.72, T = 7.84) were significantly correlated with caregiver burden, although the strength of association was more than two times higher for behavior. In Group 2, behavior was related to caregiver burden (B = 0.68, T = 6) but not function-cognition (B = 0.16, T = 1.36). CONCLUSION: These findings suggest that behavioral symptoms are an important factor associated with caregiver burden in patients with cognitive impairment, dementia, or depression, while functional and cognitive factors seem to also have an influence in patients with cognitive impairment.

RESUMO

Mild cognitive impairment (MCI) refers to persons who are slightly cognitively impaired for age but do not meet the criteria for dementia. MCI has been related to a pre-dementia stage of Alzheimer's disease (AD). However, other possible diagnoses such as cerebro-vascular disease, frontotemporal dementia or normal aging have been considered. Diagnosis, etiology and conversion to dementia are a source of ambiguity in MCI. The aim was to evaluate the opinion of experts on dementia and of general practitioners concerning MCI. A total of 24 experts from Argentina and Brazil (16 neurologists and 8 psychiatrists) and 30 general practitioners agreed to reply to a questionnaire on MCI (adapted from Dubois inventory, 2003). Of these, 92% of experts considered MCI as an ambiguous entity, not necessarily as a "pre-dementia" stage; 63% confirmed a tendency to worsen over the time and 83% of experts decided to initiate treatment using cholinesterase inhibitors, memantine and vitamin E. The opinion on MCI was that a priori it is not only an Alzheimer disease pre-dementia stage, but most of them consider the treatment against AD. MCI is a heterogeneous entity that should be classified as an open category and making it necessary to standardize definitions and design diagnosis guides to better understand Alzheimer disease pre-dementia stage.

RESUMO

UNLABELLED: The mild cognitive impairment (MCI), has emerged as an identifiable condition and in many cases is an intermediate state preceding diagnosable Alzheimer disease (AD) characterized by acquired cognitive deficits, without significant decline in functional activities of daily living. The aim of this study was to determine both the presence and type of neuropsychiatric manifestations in MCI patients and to compare them with both those suffering from mild AD and normal controls. METHODS: 86 subjects were assessed, 27 were classified as having MCI, 39 as having presumable mild AD, and 20 normal controls matched by age and education. The Neuropsychiatric inventory (NPI-Q) was used to assess the neuropsychiatric manifestations. RESULTS: The most common symptoms in the MCI group were irritability (55%), dysphoria (44%), apathy (37%), and anxiety (37%). Statistically significant differences were observed between the MCI and control groups regarding the above mentioned symptoms (p0.05). However, the differences between the MCI and mild AD groups were not found to be statistically significant. CONCLUSION: MCI is associated with a high rate of neuropsychiatric symptoms (irritability, depression, anxiety and apathy). These symptoms have serious adverse consequences and should be considered in diagnosis criteria.

RESUMO

UNLABELLED: Depression is named as one of the most prevalent Mental Health problem, affecting almost 10 % of the population. According to Diagnostic and Statistical Manual of Mental Disorders (DSM-IV) different subtypes are included. Dysthymic Disorder is characterized by a depressed mood for most of the day, for more days than not, as indicated either by subjective account or observation by others, for at least 2 years. The aim of this study was to investigate the neuropsychological profile of dysthymic disorder. Ninety three patients fulfilling criteria for dysthymia were examined on a variety of cognitive tasks, neurological exam and a semi-structured psychiatric interview. Forty one non-depressed individuals served as controls. Significant differences between groups were found in digit span; immediate and delayed recall of a story; and semantic and phonologic fluency. Logic memory was worse than serial learning task, and has a correlation with attention deficit and depressive features. CONCLUSIONS: This results indicate that the neuropsychological performance of patients with dysthymic disorder exhibit impairments in attention and memory. Attentional deficits appear to be the key of cognitive deficits in dysthymia.

RESUMO

ABSTRACT. The MoCA is a brief useful test to diagnose mild cognitive impairment (MCI) and mild dementia (MD). To date, no Argentine cross-cultural adapted validations of the Spanish version have been reported. Objective: To validate the MoCA in the elderly and study its usefulness in MCI and MD. Methods: This study included 399 individuals over 60 years old evaluated in the Cognitive-Behavioral Department (2017-2018). Patients with<3 years of education, sensory disturbances, psychiatric disorders, or moderate-severe dementia were excluded. The control group comprised cognitively normal subjects. Participants were classified according to neuropsychological assessment and clinical standard criteria into Control, MCI or MD groups. A locally adapted MoCA (MOCA-A) was administered to the patients and controls. Results: Mean educational level was 10.34 years (SD 3.5 years). MoCA-A score differed significantly among groups (p<0.0001). MoCA-A performance correlated with educational level (r: 0.406 p<0.00001). Adopting a cut-off score ≥25 (YI=0.55), the sensitivity for MCI was 84.8% and for MD ​​100%, with specificity of 69.7%. When adding a single point to the score in patients with ≤12 years of education, the specificity of the test reached 81%. Conclusion: The MoCA-A is an accurate reliable screening test for MCI and MD in Argentina.


RESUMO. O MoCA é um teste breve e útil para diagnosticar comprometimento cognitivo leve (CCL) e demência leve. Até o momento, nenhuma validação argentina com adaptação transcultural da versão em espanhol havia sido relatada. Objetivo: Validar o MoCA em idosos e estudar sua utilidade no CCL e demência leve. Métodos: Este estudo incluiu 399 indivíduos acima de 60 anos avaliados no departamento cognitivo-comportamental (2017-2018). Foram excluídos pacientes com menos de 3 anos de escolaridade, com distúrbios sensoriais, distúrbios psiquiátricos e demência moderada a grave. O grupo controle foi cognitivamente normal. Eles foram classificados de acordo com a avaliação neuropsicológica e os critérios clínicos padrão em Controles, MCI e demência leve. A versão adaptada do MoCA (MOCA-A) foi administrado aos pacientes e controles. Resultados: Média de escolaridade: 10,34 anos (DP: 3,5). O escore MoCA-A foi significativamente diferente entre os grupos (p<0,0001). O MoCA-A correlacionou-se com a escolaridade (r=0,406 p<0,00001). Com uma pontuação de corte ≥25 (IY=0,55), a sensibilidade para CCL foi de 84,8% e para demência leve 100%, com especificidade de 69,7%. Adicionando um ponto único à pontuação em pacientes com menos de 12 anos de escolaridade, a especificidade do teste atingiu 81%. Conclusão: O MoCA-A é um teste de rastreamento preciso e confiável para MCI e demência leve na Argentina.

RESUMO

Neuropsychiatric symptoms (NPS) are core features of Alzheimer's disease and related dementias. On one hand, behavioral symptoms in patients with mild cognitive impairment (MCI) can indicate an increased risk of progressing to dementia. On the other hand, mild behavioral impairment (MBI) in patients who usually have normal cognition indicates an increased risk of developing dementia. Whatever the cause, all dementias carry a high rate of NPI. These symptoms can be observed at any stage of the disease, may fluctuate over its course, are a leading cause of stress and overload for caregivers, and increase rates of hospitalization and early institutionalization for patients with dementia. The clinician should be able to promptly recognize NPI through the use of instruments capable of measuring their frequency and severity to support diagnosis, and to help monitor the treatment of behavioral symptoms. The aims of this review are to describe and update the construct 'MBI' and to revise the reported NPS related to prodromal stages of dementia (MCI and MBI) and dementia stages of Alzheimer's disease and frontotemporal lobar degeneration.
