RESUMO
INTRODUCTION: Awareness of disease is the ability to acknowledge changes caused by deficits related to the disease process. We aimed to investigate whether there are differences in awareness of disease between young-onset dementia (YOD) and late-onset dementia (LOD) and examined how awareness interacts with cognitive and clinical variables. MATERIALS AND METHODS: Using a cross-sectional design, 49 people with YOD and 83 with LOD and their caregivers were included. We assessed awareness of disease, cognition, functionality, stage of dementia, mood, neuropsychiatric symptoms, and caregivers' quality of life (QoL) and burden. RESULTS: We found that people with YOD were more aware of the disease than people with LOD (P<0.005). Multivariate linear regression revealed that higher impairment in functional level was associated with unawareness in both groups (YOD=P<0.001; LOD=P<0.001). In the YOD group, preserved awareness was related to worse self-reported QoL (P<0.05), whereas, in LOD, deficits in awareness were related to caregivers' worst perceptions about people with dementia QoL (P<0.001). CONCLUSIONS: The findings highlight the distinct nature of awareness between YOD and LOD. The YOD group had higher levels of disease awareness compared with the LOD group, even though the first group had a greater impairment in functionality.

BACKGROUND: Quality of life (QoL) is a growing area of interest in dementia research. This study aims to investigate the caregivers' perspective about the QoL of people with young-onset Alzheimer disease (YOAD) and late-onset Alzheimer disease (LOAD). We also aim to investigate factors that might be associated to caregivers' perspective in YOAD and LOAD. METHODS: We included 110 people with Alzheimer disease (PwAD; 53 YOAD) and their primary caregivers. The PwAD completed assessments about their QoL and cognition. The caregivers provided information about the PwAD (demographics, QoL, ability to perform activities of daily living, mood, and dementia severity) and had burden of care assessed. RESULTS: We did not find a difference in caregivers' perspectives of PwAD QoL according to the age at onset. However, the linear regression analysis indicated that caregivers' burden ( P < .01) and PwAD depressive symptoms ( P < .05) were significantly related to the caregivers' perspective of YOAD QoL. Caregivers' burden ( P < .01), years of education ( P < .05), and self-reported QoL ( P < .01) were significantly related to the caregivers' perspective of LOAD QoL. CONCLUSIONS: The factors that drive the perceptions of caregivers of PwAD QoL may vary according to the age at onset. The study provides basic information on caregivers' perspectives of PwAD QoL to create more effective interventions according to the age at onset.

INTRODUCTION: Young onset dementia (YOD) develops before 65 years of age and has specific age-related adverse consequences for quality of life (QoL). We systematically examined factors related to the QoL of people with YOD and their caregivers. METHOD: This systematic review used the PRISMA methodology. The literature search was undertaken on July 5, 2015, using Cochrane, PubMed, SciELO, PsycINFO, Scopus and Thomson Reuters Web of Science electronic databases. The search keywords included early onset and young onset combined with, dementia, Alzheimer, vascular dementia, mixed dementia, frontotemporal dementia, quality of life, well-being and unmet needs. Nine studies were included. We revised objectives, study design, sample, instruments and results related to QoL. RESULTS: People with YOD rated their own QoL significantly higher than their caregivers. Greater awareness of disease among people with YOD is associated with better QoL in caregivers. A relationship was found between unmet needs and daytime activities, lack of companionship and difficulties with memory. Issues associated with unmet needs were prolonged time to diagnosis, available health services and lack of caregiver's own future perspective. CONCLUSION: Consideration should be given to conducting investigations with more homogeneous samples and use of a clear concept of QoL. The present study highlights the need for future research in a wider range of countries, using instruments specifically for YOD. It would be interesting if studies could trace parallels with late onset dementia groups.

Introdução A demência de início precoce se desenvolve antes dos 65 anos e possui consequências adversas específicas relacionadas à idade para a qualidade de vida (QV). Nós examinamos de forma sistemática fatores ligados à QV de pessoas com demência de início precoce e seus cuidadores. Método Foi utilizada a metodologia PRISMA, com busca nas bases de dados Cochrane, PubMed, SciELO, PsycINFO, Scopus e Thomson Reuters Web of Science electronic em 5 de julho de 2015. Foi utilizada a palavra-chave início precoce combinada com demência, Alzheimer, demência vascular, demência mista, demência frontotemporal, qualidade de vida, bem-estar e necessidades não atendidas. Nove estudos foram incluídos. Foram revisados os objetivos, desenho, amostra, instrumentos e resultados relacionados à QV. Resultados Pessoas com demência de início precoce pontuaram sua própria QV significantemente mais alta que seus cuidadores. A maior consciência da doença entre essas pessoas é associada com melhor QV dos cuidadores. Foi encontrada relação entre necessidades não atendidas e atividades diárias, falta de companhia e dificuldades com a memória. A demora na definição do diagnóstico, os serviços de saúde disponíveis e a falta de perspectivas futuras do cuidador foram fatores associados às necessidades não atendidas. Conclusão Deve-se considerar a possibilidade de conduzir investigações com amostras mais homogêneas e um conceito mais claro de QV. O presente estudo chama atenção para a necessidade de pesquisas em mais países, utilizando instrumentos específicos para pessoas com demência de início precoce. Seria interessante se estudos pudessem traçar paralelos com grupos de início tardio.
