Introdução: O comprometimento cognitivo (CC) na Esclerose Múltipla (EM) possui taxas de prevalência de 43% a 70% e pode surgir desde a Síndrome Clinicamente Isolada (CIS) aos estágios iniciais da EM. O CC na EM pode evoluir independentemente dos sinais e sintomas motores, dos resultados do EDSS e ausência de lesões ativas (captantes) na Ressonância Magnética. Neste contexto, o Multiple Sclerosis National Questionaire (MSNQ) e o protocolo Brief International Cognitive Assesment for Multiple Sclerosis (BICAMS) são instrumentos internacionais empregados para a triagem e o monitoramento nos centros de atendimento para os pacientes com EM. Estudos posteriores e reuniões do mesmo comitê concluíram que o MSNQ possui várias limitações por ser uma medida não objetiva e a triagem única pelo Symbol Digit Modalities Test (SDMT) por si só não é capaz de acessar outras áreas que podem estar comprometidas na EM. Com a segunda revisão do MMSE, e na falta de instrumentos de triagem objetivos capazes de triar os pacientes que precisassem ser melhor acompanhados pelo BICAMS, buscou-se no presente estudo criar a partir do BICAMS e do MMSE-2 uma medida rápida para triagem, que tivesse medidas de memória episódica, velocidade de processamento, atenção e memória operacional. Objetivo: Para obter uma ferramenta de triagem para este propósito (MMSE-MS) foram conduzidos estudos de adaptação segundo o estímulo: estudo de protótipos, estudo de adaptação, propriedades psicométricas e normas do MMSE-2 (como a nossa ferramenta experimental) e estudo preliminar de desenvolvimento de uma ferramenta objetiva de triagem para EM, com base no MMSE-3. Métodos: Todos os estudos de tradução e adaptação foram conduzidos seguindo um mesmo método, já amplamente utilizado pela literatura. O primeiro estudo consistiu no estudo convencional e de protótipos para verificar qual possuía melhor estimativa de equivalência entre as culturas. O segundo estudo consistiu em adaptar, verificar as propriedades psicométricas e estabelecer normas para o MMSE-2. Similarmente ao estudo anterior, um juiz internacional discutiu os resultados do estudo de adaptação para estabelecimento dos parâmetros de transculturalidade. O último estudo foi realizado com o objetivo de obter uma ferramenta com estimativas de sensibilidade e especificidade similares ao BICAMS, mas que fosse designada à triagem dos pacientes que são elegíveis para ser acompanhados pelo BICAMS. Para tal participaram do primeiro estudo, 374 voluntários da comunidade e 25 pacientes com EM. No segundo e terceiro estudo, participaram 128 pacientes com EM e 602 voluntários saudáveis. Todos os estudos clínicos e com as amostras da comunidade foram realizados no período de 2013 à 2015 e contaram com a parceria em pesquisa do Instituto Brasileiro de Neuropsicologia (IBNeuro) e do Laboratório de Instrumentação e Avaliação Psicológica (LABIAP). A coleta de pacientes foi realizada no Ambulatório de Neuroimunologia do Hospital das clínicas da Faculdade de Medicina de Ribeirão Perto (FMRP-USP). Resultados: No primeiro estudo, foram mantidas 5 palavras das 15 da versão original. A razão para as modificações na lista Brasileira foram as diferenças entre a divisão silábica, extensão das palavras e presença de protótipos. Verificou-se ainda que até a quarta palavra evocada na nossa cultura em cada categoria semântica foram as mesmas que foram evocadas na língua nativa do instrumento, mas a ordem da frequência variou dentro de cada categoria, mostrando que embora existam palavras que são prototípicas às duas culturas na classificação semântica global, o contexto cultural interfere muito quando partimos para as especificidades dentro de cada classificação e categoria semântica. O MMSE-2 também apresentou estimativas de validade e precisão comum às duas culturas. No quarto estudo, as medidas do MMSE-2 que tiveram melhor relação com o BICAMS e índices de sensibilidade e especificidade parecidos foram as medidas da tarefa de evocação, atenção e cálculo, memória de histórias e codificação dígitos-símbolos. As correlações selecionadas foram aquelas classificadas em moderadas e fortes. Como segundo critério, as medidas do MMSE-2 foram comparadas às medidas do BICAMS pela curva ROC. As medidas do MMSE- 2 que tiveram especificidade e sensibilidade significativas (p<0,001) foram as elegíveis para compor o teste de triagem. Como a tarefa de codificação dígitos-símbolos é susceptível à demanda motora, optou-se pelo uso da forma oral do SDMT em conjunto. Deste modo, no nosso instrumento de triagem, normas para este instrumento foram criadas a partir da soma dos itens do MMSE-MS com o SDMT oral. Conclusão: A integração de dados desses diversos estudos evidencia cautela quanto aos procedimentos de adaptação empregados para adaptação transcultural das tarefas que são de origem verbal e semântica. Há também evidências da necessidade de instrumentos capazes de triar esses pacientes. Para tal, o MMSE-EM mostrou-se válido, preciso, com índices de sensibilidade e especificidade similares ao BICAMS, com normas ajustadas ao contexto Brasileiro. / Background: The cognitive impairment (CI) in Multiple Sclerosis (MS) has the prevalence rate from 43% to 70% and may occur from the Clinically Isolated Syndrome (CIS) to the early stages of MS. The CI in MS can advance independently of motor signs and symptoms, EDSS scores and MRI stable. In this context, the National Multiple Sclerosis Questionnaire (MSNQ) and the International Brief Cognitive Assesment for Multiple Sclerosis (BICAMS) are international tools used to screening and monitoring MS patients in care centers. Further studies and meetings provided by same committee alluded that MSNQ has several limitations for being a non-objective measure and the screening using the Symbol Digit Modalities Test (SDMT) alone is not effective because other areas that may be impaired in MS is not screened. With the second revision of the MMSE, and the lack of objective screening tools to quikly screening MS patients that needed to be monitored by BICAMS, we aimed in the presente study to create a fast measurement to screening the episodic memory, processing speed, attention and working memory from BICAMS and MMSE-2. Objective: To obtain brief a screening tool for MS (MMSE-MS) were conducted four studies using different tools: first the prototype study to development of CVLT-2 lists, adaptation, psychometric properties and normative data of BICAMS to the Braziliam context (as our gold standard), Cross cultural adaptation, psychometric properties, and normative data of MMSE-2 (the experimental tool) and the preliminary study of development of MMSE-MS. Methods: All translation and adaptation studies were conducted following the same method, as widely used in the literature. The first study consisted of conventional adaptation and prototypical norms, aiming to see which had the best estimates of equivalence between the cultures. The second study with BICAMS protocol show that MS scored significantly lower on all BICAMS tests. At the end of the study, the results were discussed with a member of the international committee to confirm the evidences of transculturality between the original and Brazilian versions. The third study consisted of Adapt, to investigate the psychometric properties and stablish normative data to the MMSE-2. Similarly to the previous study, an international judge discussed the results of the study of adaptation to identify the estimatives of transculturality. The fourth and last study was conducted in order to obtain a tool with sensitivity and similar specificity estimates BICAMS, but it was designed to screen patients who are eligible to be accompanied by BICAMS. Participated of the first study, 374 healthy volunteers and 25 patients with MS. In the second and third study participated 128 MS patients and 602 healthy volunteers. All clinical studies and community samples were carried out from 2013 to 2015 and had the partnership of the Brazilian Institute of Neuropsychology (IBNeuro) and the Laboratory of Instrumentation and Psychological Assessment (LABIAP). The collection of patients was performed at the Neuroimmunology Outpatient Clinic from Ribeirão Preto Medical School (FMRP-USP). Results: In the first study, were kept 5 words of 15 from the original American version. The reason for these changes in the Brazilian list were the differences between the syllabic division, extension of the words and the presence of prototypicall words. Was also found that until the fourth word evoked in our culture, in each semantic category were the same as those mentioned in the native language, but the order of the frequency varied within each category, indicating that although there are words that are prototypically commom between the two cultures in the overall semantic classification, the cultural context changes when we analyse the specifics prototipically words inside of each classification and semantic categories. To the second study, the BICAMS showed similar estimates of reliability and validity for current use as monitoring tool for MS in the Brazilian contexto, supporting the diagnostic validity of the Brazilian-Portuguese adaptation The normative data were satisfactory (p <0.001) in relation to the vocational status. The third study, with MMSE-2 also provided good estimates of validity and precision to the both cultures. To the fourth study, the MMSE-2 was compared to the BICAMS. The MMSE-2 tasks which had similar sensitivity and specificity to the BICAMS protocol was the recalling, attention and calculation, history memory and processing speed (Symbol Digit-coding). The selected tasks were those classified as moderate and Strong correlations. The second procedure consisted on comparisions among the MMSE-2 measurements and BICAMS using ROC curve. So, the MMSE-2 measures that had significant (p <0.001) specificity and sensitivity and similar area under the curve (ROC) were eligible to composse the screening tool. As the digit-symbol coding task is susceptible to motor demand, we decided to include the oral SDMT to the task. Thus, to get our screening tool, normative data for this instrument were created from the sum of the MMSE-MS items with oral SDMT. Conclusion: The overall of the data from these studies calls attention to the necessity of the caution to the adaptation procedures used in cross-cultural adaptation of the tasks that has verbal and semantic stimuli. There is also the need of tools abel to screening MS patients. For this, these preliminar data for MMSE-MS showed evidences of validation, similar sensitivity and and specificity, with normative data culturally adjusted to the Brazilian context.

The population of China is ageing. Accompanying this aging population, dementia and frailty have a growing importance. However there is little consensus on the association between dementia and frailty, in terms of how the criteria that are part of this two syndromes overlap, as both disorders are age-related and increase the risk for falls, further leading to loss of independence. To meet the above needs, the thesis describes research into different frailty diagnostic criteria, as well as its association with dementia symptoms. We examined cognitive measures that can be used for assessment of Mild Cognitive Impairment (MCI) and dementia screening (the Hopkins Verbal Learning Test, HVLT) and compared its discriminant ability with the commonly used cognitive screening tool, the Mini-Mental State Examination (MMSE) in distinguishing Cognitive Impairment (including MCI and dementia) from No Cognitive Impairment (NCI, normal controls) in two community-dwelling elderly Chinese populations and in one institutionalised elderly population in Shanghai, China. Subsequently we investigated whether physical and cognitive symptoms clustered together to form frailty phenotypes. We employed indicators that have been widely used to diagnose frailty, including physical measures (grip strength, Time-Up and Go test, 15 feet gait speed test and Berg balance test), and psychological measures (the HVLT and the MMSE) to predict cognitive impairment (CI) and frailty. Additionally, we described demographics (age, gender, education) and other potential modifiers when detecting cognitive impairment and functional disability. We then built up a model for possible frailty phenotype using various indicators. Lastly, we examined whether demographic (age, gender, education and profession), and lifestyle (smoking/alcohol history, exercise frequency, and dietary habit) could be used to predict future cognitive impairment. It was found that advanced age, lower education (no or primary level), and being vegetarian were significant risk factors for cognitive impairment. Furthermore, whereas high consumption of green vegetables is a protector against cognitive impairment, high intake of tofu was negatively related to cognitive performance among community-dwelling elderly in China. To meet the above needs, the thesis describes research into different frailty diagnostic criteria, as well as its association with dementia symptoms. We examined cognitive measures that can be used for assessment of Mild Cognitive Impairment (MCI) and dementia screening (the Hopkins Verbal Learning Test, HVLT) and compared its discriminant ability with the commonly used cognitive screening tool, the Mini-Mental State Examination (MMSE) in distinguishing Cognitive Impairment (including MCI and dementia) from No Cognitive Impairment (NCI, normal controls) in two community-dwelling elderly Chinese populations and in one institutionalised elderly population in Shanghai, China. Subsequently we employed these two cognitive measures to investigate whether they were part of the frailty syndrome among elderly from the community-based studies. We investigated whether physical and cognitive symptoms clustered together to form frailty phenotypes. We employed indicators that have been widely used to diagnose frailty, including physical measures (grip strength, Time-Up and Go test, 15 feet gait speed test and Berg balance test), and psychological measures (the HVLT and the MMSE) to predict cognitive impairment (CI). We found four distinct subtypes of elderly characterised by increasing care needs: 1. Persona elderly as defined by age >78, year of education<6 years, grip strength <11.8 KG, and a MMSE total score <25; 2. Persona Physical frailty (fitness), defined by a total score on the Timed-Up and Go (TUG) test >12.7 seconds and 15 feet gait speed >4.4 seconds; 3. Persona Cognitive impairment, defined by a MMSE total score <25, a HVLT Immediate Recall (IR) score <15, and a HVLT Delayed Recall (DR) <5; 4. Persona Physical frailty (balance,) defined by a Berg Balance test score of <53. Additionally, we described demographics (age, gender, education) and other potential modifiers when detecting cognitive impairment and functional disability. We then built up a model for possible frailty phenotype using various indicators, Frailty here was defined as: 1. Low BMI as measured by this algorithm: BMI= Weight (kg)/Height (m)2 2. Weakness (upper and lower body): grip strength in the lowest quintile, adjusted for gender; and TUG get up with assistance or unable to get up 3. Slowness (lower body): TUG score in the lowest quintile, adjusted for gender; and 15 feet gait speed in the lowest quintile, adjusted for gender; 4. Poor balance: Berg Balance test score in the lowest quintile, adjusted for gender; 5. Low physical activity: engaging in exercise less than once per week. An individual with 4 or more present frailty components out of a total of 7 was considered to be frail , whereas equal or less than 3 characteristics were hypothesized to be pre-frail . Those with no present frailty components were considered as robust. Lastly, we examined whether demographic (age, gender, education and profession), and lifestyle (smoking/alcohol history, exercise frequency, and dietary habit) could be used to predict future cognitive impairment (as defined by a HVLT IR score of ≤19). The results of our studies show that compared to the MMSE, the HVLT is superior in differentiating MCI and dementia from NCI, and is also less affected by demographic factors in detecting frailty. Furthermore, in the current study, physical, psychological, demographic and other modifiable risk factors cluster together into different phenotypes of cognitive impairment and functional disability in these cohorts. A phenotype of frailty is built up using BMI, grip strength, TUG, 15 feet gait speed, balance and exercise frequency as indicators. The most common was the elderly phenotype followed by the cognitively impaired. A novel finding of the current study is that only 4.8% (8 out 168) of the whole sample fulfilled all three categories in the current study (cognitive impairment, functional disability and frailty). Finally, advanced age, lower education (no or primary level), and being vegetarian were significant risk factors for cognitive impairment. Furthermore, whereas high consumption of green vegetables is a protector against cognitive impairment, high intake of tofu was negatively related to cognitive performance among community-dwelling elderly in China.

Accurate, early diagnosis of Alzheimer's Disease is becoming increasingly important in light of its growing prevalence among the expanding older-aged adult population. Due to its ability to assess multiple domains of cognitive functioning and provide a profile of impairment rather than a simple global score, the Neurobehavioral Cognitive Status Examination (NCSE) is suggested to better assess such patterns of cognitive deficit for the purpose of diagnosis. The performance of the NCSE was compared with that of the Mini-Mental State Examination (MMSE) for diagnostic sensitivity in a sample of patients diagnosed as having probable Alzheimer's Disease. The strength of correlation between severity of cognitive impairment on these tests and report of behavior problems on the Memory and Behavior Problems Checklist (MBPC) was also explored, as was performance on the NCSE and report of behavior problems using the MBPC in predicting Single Photon Emission Computed Tomography (SPECT) scan results. The NCSE was found to exhibit greater sensitivity to physician diagnosis of probable Alzheimer's Disease relative to two versions (Serial 7's or WORLD) of the MMSE (.90, .77 and .68, respectively). While both measures were found to correlate significantly with the report of behavior problems, only a moderate proportion (NCSE = .22 and MMSE = .33) of the explained variance was accounted for by either test. Severity of cognitive impairment on the NCSE was found to be significant, though small in estimate of its effect size, for predicting the absence/presence of pathognomic findings on SPECT scans. In contrast, the report of behavior problems on the MBPC did not significantly predict SPECT scan outcomes. The NCSE would appear to be a sensitive tool for the identification of the extent and severity of cognitive impairment found among demented individuals; however, it may be "over"-sensitive to such diagnosis. Although relationships between cognitive impairment and behavior problems and/or neuroradiological findings are observed, their meaningfulness remains with the need for further, more detailed, study using standardized criteria for comparison purposes.

This study has the objective of investigating the performance of adults and seniors in terms of working memory skills and at the Mini-Exam of Mental State, verifying how these skills relate to each other, to the age and to the scholarship level. The sample was composed by 34 people, with ages among 37 and 83 years-old, Brazilians, Portuguese speakers, literate and without any evident and referred neurological and/or cognitive alterations and it was shared into four groups according to the age group. The adults and seniors performance at the working memory assessments was checked through the repetition of non-words task to assess specifically the phonological memory and the repetition of a sequence of digits to assess the central executive and the phonological memory, according to Baddeley and Hitch s proposal (1974 apud GATHERCOLE & BADDELEY, 1993). The Mini-Mental State Examination, Folstein and McHugh s proposal (1975), was used to assess the orientation, immediate memory, attention, calculation, mandate, language, reading and constructive praxis. In order to analyze the co-relation among the evaluations it was used the non parametric test, the Sperarman s Correlation Coefficient, from which it was identified: 1) the younger people had a better performance at the three tasks applied when compared with the older ones; 2) there was a significant correlation between the repetition of non-words and repetition of a sequence of digits tasks; 3) the Mini-Mental State Examination has a small correlation with the memory working tasks; 4) it was observed significant correlation of age and scholarship with the tasks of repetition of non-word, repetition of a sequence of digit and Mini-Mental State Examination. Comparing the four groups, it was verified that the rightness average at the three assessmests diminished as much as the age group increased. It was observed that the rightness averages at the working memory and Mini- Mental State Examination tasks increased according to the scholarship level. It concluded that older people with low scholarship level, considered as a group not individually, present smaller performance at the working memory and Mini-Mental State Examination tasks than younger people and with higher scholarship level / Este estudo teve por objetivo investigar o desempenho de adultos e idosos em habilidades de memória de trabalho e no Mini-Exame do Estado Mental, verificando como estas habilidades relacionam-se entre si, com a faixa etária e com o nível de escolaridade. A amostra foi formada por 34 sujeitos, com idades entre 37 e 83 anos, brasileiros, falantes do português, alfabetizados e sem alterações neurológicas e/ou cognitivas evidentes e referidas, e foi dividida em quatro grupos conforme a faixa etária. O desempenho dos adultos e idosos nas avaliações de memória de trabalho foi verificado através da tarefa de repetição de não-palavras para avaliar especificamente a memória fonológica, e da tarefa de repetição de seqüência de dígitos para avaliar o executivo central e a memória fonológica, segundo a proposta de Baddeley & Hitch (1974 apud GATHERCOLE & BADDELEY, 1993). O Mini-Exame do Estado Mental, proposto por Folstein & McHugh (1975), foi utilizado para avaliar orientação, memória imediata, atenção, cálculo, evocação, linguagem, leitura e praxia construtiva. Para analisar a correlação entre as medidas foi utilizado o teste não-paramétrico Coeficiente de Correlação de Spearman, através dos quais verificou-se que: 1) os sujeitos mais jovens desempenharam melhor as três tarefas aplicadas quando comparados com os sujeitos mais velhos; 2) houve correlação significativa entre as tarefas de repetição de não-palavras e repetição de seqüência de dígitos; 3) o Mini-Exame do Estado Mental apresentou fraca correlação com as tarefas de memória de trabalho; 4) houve correlação significativa entre idade e escolaridade com as tarefas de repetição de nãopalavras, repetição de seqüência de dígitos e com o Mini-Exame do Estado Mental. Na comparação entre os quatro grupos, verificou-se que as médias de acertos nas três avaliações aplicadas diminuíram conforme a faixa etária aumentou. Comparando-se as médias de acertos nas tarefas de memória de trabalho e no Mini-Exame do Estado Mental de acordo com o grau de escolaridade, observou-se que as médias nas tarefas analisadas aumentaram em função do grau de escolaridade. Concluiu-se que sujeitos mais velhos e com baixa escolaridade, quando considerados como um grupo e não individualmente, apresentam desempenho inferior nas tarefas de memória de trabalho e no Mini-Exame do Estado Mental do que os sujeitos mais jovens e com níveis mais altos de escolaridade

This thesis deals with the neuropsychological diagnosis of Alzheimer's disease. The aim is to evaluate the psychometric characteristics ofthe new Czech translation of the Montreal Cognitive Assessment (MoCA) by comparison with the Mini-Mental State Examination (MMSE), a method widely used by doctors inscreening diagnostics of Alzheimer's disease. The theoretical part deals with the diagnostics of Alzheimer's disease and mild cognitive impairment. We describe international diagnostic criteria of cognitive disorders and provide an overview of the screening neuropsychological methods most commonly used by Czech specialists. We summarize the current psychometric and psychodiagnostic findings on these methods and focuse on description of MMSE and MoCA. In the empirical part we compare Czech version of MMSE and MoCA-CZ (the new Czech translation of the test). We examined 38 patients with Alzheimer's disease and 70 cognitively healthy seniors. The results show that MoCA-CZ is sufficiently valid and reliable screening method that accurately distinguishbetween healthy subjects and patiens with Alzheimer's disease. We believe that it can enrich screening tools that are available to Czech experts. Key words: Montreal Cognitive Assessment, Mini-Mental State Examination, Alzheimer's disease, psychodiagnostics,...

The present study investigated the criterion-based validity of the Mini-Mental State Examination (MMSE), the Cognitive Capacity Screening Examination (CCSE), and the Neurobehavioral Cognitive Status Examination (NCSE) in a sample of older adults with suspected cognitive impairment. As cognitive screening tests, the MMSE, CCSE, and NCSE should predict performance relative to a more thorough testing procedure. In the present study, performance on the Halstead-Reitan Neuropsychological Test Battery (HRNTB) was employed as the criterion measure. Scores on the General Neuropsychological Deficit Scale (G-NDS), a global performance measure computed from the HRNTB, served as the standard by which to judge the presence of cognitive impairment. The sensitivity, specificity, and predictive value of each screening test, as well as how well each screening test correlated with the G-NDS, were investigated. Results of this investigation found that, although the MMSE, CCSE, and NCSE were all significantly correlated with the G-NDS, only the NCSE demonstrated an appropriate balance between high sensitivity and specificity. When a rigorous neuropsychological evaluation was employed as the criterion standard, the NCSE accurately detected the presence of cognitive impairment: in 82% of the cases. The MMSE and CCSE, however, failed to detect cognitive deficits in approximately 80% of the cases. These findings strongly suggest that the MMSE and CCSE may have limited utility in the identification of cognitive impairment in older adults. The heightened sensitivity of the NCSE appears to be the result of several unigue features of the instrument, including a multidimensional scoring system and a graded series of increasingly difficult items within each ability area. Future studies need to examine the utility of the NCSE in other geriatric settings, as well as with more diverse populations suffering from a variety of organic mental syndromes.

The accuracy of neuropsychological assessment is critical in the diagnosis of cognitive impairments in older adults. However, existing neuropsychological tests may not be suitable for minority populations. This thesis aimed to address this issue by recruiting cognitively-healthy South Asian older adults and assessing cognitive function in this group. Results showed that typically used assessments, despite being translated, were not suitable for this cohort. Furthermore, skills required for test completion such as mathematics and writing/hand dexterity (which are related to education levels) influenced test scores. Therefore, new assessments of general cognitive function and associative memory were developed to improve the accuracy of neuropsychological test scores. The new tests were not affected by education and they achieved high internal and test re-test reliability. Time of day (TOD) that testing takes place is also known to affect cognition. Interestingly, no TOD effects were observed in this cohort. It was hypothesised that engagement in the daily five Islamic prayers may have contributed to this lack of a TOD effect. However, the results did not confirm this. The thesis then looked at overall prayer engagement and cognition. Results showed that engagement in the daily five prayers and Quran recitation significantly increased scores on assessments of processing speed. This thesis demonstrates that accurately assessing cognition in South Asian older adults is challenging and that the cognitive tests used must be suitable for this cohort. Interesting findings emerged for prayer engagement which may have wider implications for the field of cognitive reserve.

The main goal of the thesis entitled "The selected methods of social work with clients self-non sufficient in health care facilities" was to describe and to analyze methods used in activation of the elderly suffering from dementia. It draws a comparison of different settings and explores workers's attitude to the methods of activation. The text of the thesis was mapped out into five chapters. The first chapter was set into the context of old age and ageing. The second chapter is concerned with the issues of self-sufficiency and dependency of old age and other related issues. The topic of the third chapter is old age in relation with memory. It defines memory and memory disorders in the elderly suffering from dementia. The fourth chapter is crucial and gives an idea of non-pharmacological and other possible activities which are eligible for application in practice and are intended to reduce cognitive disorders of cognitive functions and behavior disorders. The theoretical part enters into research carried out in four facilities which care for clients with dementia. The research section is represented by a qualitative research where methods of a half structured interview and observation were opted for. The interviews were realized with eight practicing experts. The outcomes gathered from the...
