BACKGROUND: Body composition, blood pressure, estimated maximal oxygen uptake (VO2max), lung function, physical activity, muscle architecture, and endothelial function had not previously been examined in people with young onset dementia. Therefore, the study measured these variables in a young onset dementia group, compared them to age-matched controls.
METHODS: Estimated VO2max (via the Astrand-Rhyming test), body composition, blood pressure, lung function (via spirometry), muscle architecture (via ultrasonography) and endothelial function (via flow mediated dilation) were assessed. Physical activity was measured using ActiGraph accelerometers for 7 days.
RESULTS: We recruited 33 participants (16 young onset dementia, 17 controls). The young onset dementia group had shorter fascicle lengths of the vastus lateralis, were sedentary for longer over a seven-day period, and completed less moderate-vigorous physical activity than controls (p=0.028, d=0.81; large effect, p=0.029, d=0.54; moderate effect, and p=0.014, d=0.97; large effect, respectively for pairwise comparisons). Pairwise comparisons suggest no differences at the p<0.05 level between young onset dementia and controls for estimated VO2max (despite a moderate effect size [d=0.66]), height, body mass, BMI, blood pressure, light physical activity, lung function, muscle thickness, pennation angle, or endothelial function.
CONCLUSIONS: This study highlights differences between people with young onset dementia and controls, underscoring the need for multicomponent exercise interventions. Future interventions should target muscle architecture, increase moderate-vigorous physical activity, and reduce sedentariness, with the goal of improving quality of life and promoting functional independence.

UNASSIGNED: Young-onset dementia (YOD) refers to dementia occurring before the age of 65, with Alzheimer\'s disease being the most common form, posing distinct challenges for spousal caregivers.
UNASSIGNED: This study aims to investigate the unique experiences of spousal caregivers of persons with YOD in China, where dementia-specific community care services and primary healthcare professionals are relatively lacking, in order to inform the tailored support services development.
UNASSIGNED: This qualitative-design study utilized semi-structured interviews with 11 spousal caregivers of persons with YOD dwelling in the community. Traditional content analysis was employed to analyze the interview data.
UNASSIGNED: Limited dementia-specific healthcare professionals and low public awareness made diagnosing and accepting YOD a prolonged and challenging journey. Spousal caregivers faced skepticism when seeking diagnosis, exacerbating their burden and emotional stress. Disparities in healthcare professionals and insufficient collaboration between institutions worsened the situation. YOD significantly impacted family dynamics and led to changes in emotional communication within the family. The stigma surrounding YOD raised concerns among spousal caregivers about their children\'s future in marriage and career, emphasizing genetic risks.
UNASSIGNED: In settings where dementia-specific community care services and primary healthcare professionals are limited and unevenly distributed, integrating support services at both the primary and community levels is crucial for families dealing with YOD in the community. Additionally, raising public awareness about YOD can foster a more understanding and supportive environment, addressing challenges related to stigma faced by affected families, contributing to increased investment in supporting resources, and encouraging individuals to seek help early on.

BACKGROUND: The distinctive differences in clinical needs and disease trajectory between persons with young-onset (YOD) and late-onset dementia (LOD) make dementia palliative care unique. Limited studies have reported on the differences in palliative care needs between YOD and LOD, and the optimal time point to introduce palliative care in YOD remains controversial. We performed a systematic review to summarize key issues surrounding palliative care in YOD and highlight unmet needs in this pertinent area.
METHODS: Following the Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) guidelines, we searched the PubMed database for all studies published between January 2000 and July 2022 that reported on palliative care in YOD.
RESULTS: Of 32 records identified, 8 articles were eligible for inclusion. The top 3 themes extracted centered around (1) clinical differences between YOD and LOD, (2) symptoms and causes of death in end-stage YOD, and (3) the importance of early advanced care planning (ACP). YOD diagnosis is often delayed and persons with YOD have fewer somatic comorbidities but more neuropsychiatric symptoms, longer survival times, and a more malignant disease course. Persons with YOD and their families face unique psychosocial challenges when symptoms start at a younger age. End-stage YOD is not dissimilar to LOD where patients suffer from a broad spectrum of physical and psychological symptoms requiring palliation. Early initiation of ACP discussion is crucial in YOD given the more rapid progression of disease affecting cognition and decision-making capacity; however, rates of ACP completion in YOD remain low.
CONCLUSIONS: Given the complex care needs and more rapid disease trajectory in YOD, palliative care in YOD should be considered from the time of diagnosis, and to be incorporated into routine dementia care.

The WHO Dementia Global Action Plan states that rehabilitation services for dementia are required to promote health, reduce disability, and maintain quality of life for those living with dementia. Current services, however, are scarce, particularly for people with young-onset dementia (YOD). This article, written by an international group of multidisciplinary dementia specialists, offers a three-part overview to promote the development of rehabilitation services for YOD. Firstly, we provide a synthesis of knowledge on current evidence-based rehabilitative therapies for early-onset Alzheimer\'s disease (EOAD), behavioural variant frontotemporal dementia (bvFTD), primary progressive aphasia (PPA), and posterior cortical atrophy (PCA). Secondly, we discuss the characteristics of rehabilitation services for YOD, providing examples across three continents for how these services can be embedded in existing settings and the different roles of the rehabilitation multidisciplinary team. Lastly, we conclude by highlighting the potential of telehealth in making rehabilitation services more accessible for people with YOD. Overall, with this paper, we aim to encourage clinical leads to begin introducing at least some rehabilitation into their services, leveraging existing resources and finding support in the collective expertise of the broader multidisciplinary dementia professional community.

Dementia is associated with older adults; however, it can also affect younger individuals, known as young-onset dementia (YOD), when diagnosed before the age of 65 years. We aimed to conduct a retrospective cohort study involving middle-aged women to investigate the association between premorbid depression and YOD development.
We included 1.6 million women aged 40-60 years who underwent health checkups under the Korean National Health Insurance Service and investigated the association between depression and YOD.
Women with depression had a significantly higher risk of developing YOD than women without depression. Among premenopausal women, those with depression had a 2.67-fold increased risk, whereas postmenopausal women with depression had a 2.50-fold increased risk. Late age at menarche (> 16 years) and young age at menopause (< 40 years) was associated with an increased risk of YOD.
Depression in middle-aged women is a significant risk factor for the development of YOD. Understanding the role of reproductive factors can aid in the development of targeted therapeutic interventions to prevent or delay YOD.

BACKGROUND: People living with young-onset dementia and their care-partners are at risk of a range of adverse mental health outcomes and social isolation. There are few interventions aimed at supporting couples affected by young-onset dementia, which poses unique psychosocial challenges for younger people.
METHODS: This pre-post interventional mixed methods pilot study aimed to assess the feasibility and acceptability of an online group program for people with young-onset dementia and their care-partners living at home in Australia. The Music And Psychology and Social connections (MAPS) program aimed to address: (1) the challenges and changes associated with young-onset dementia; and (2) coping and wellbeing. The program involved six weekly two-hour sessions co-facilitated by a psychologist and music therapist, and a private Facebook group. The primary outcomes of feasibility and acceptability were assessed through a post-program focus group, separate individual feedback sessions with each couple, and a program evaluation questionnaire. Thematic analysis was conducted on the focus group transcripts and field notes from couple feedback sessions. We also examined the preliminary utility of MAPS in improving mental health and social connectedness, using quantitative pre-post-measures.
RESULTS: Five couples completed the MAPS program. The most common dementia type was Alzheimer\'s Disease. Participant attendance was 87% across all sessions. Qualitative findings supported acceptability of the program with four emergent themes: being connected to others with shared experiences; reframing thoughts and feelings about dementia; music as a therapeutic tool; and benefits of MAPS.
CONCLUSIONS: The high retention rate, qualitative findings and positive program evaluation suggest MAPS may be a promising, feasible and acceptable program for couples affected by young-onset dementia.

UNASSIGNED: Few studies have examined the characteristics of domestic violence (DV) committed by people with dementia. We provide an overview of DV perpetrated by people with dementia in the community based on police reports of attendances at DV events.
UNASSIGNED: A text mining method was used on 416,441 New South Wales (NSW) police narratives of DV events from January 2005 to December 2016 to extract information for Persons of Interest (POIs) with mentions of dementia.
UNASSIGNED: Events involving those with dementia accounted for a relatively low proportion of total DV events (<1%). Of the 260 DV events with a dementia mention for the POI, the most common abuse types were assault (49.7%) and verbal abuse (31.6%). Spouses were the largest group of victims (50.8%) followed by children (8.8%). Physical abuse was common, occurring in 82.4% of events, but injuries were relatively mild. Although weapons were infrequently used, they were involved in 5% of events, mostly by POIs aged 75 years and older. Similarly, the POIs were mainly aged 75+ years (60%), however the proportion of those aged <65 was relatively high (20.8%) compared to the reported prevalence of dementia in that age group.
UNASSIGNED: This study demonstrates that some cases of DV perpetrated by people with reported dementia are significant enough to warrant police involvement. This highlights the need to proactively discuss the potential for violence as part of the holistic management and support family members, particularly those caring for people with young-onset dementias.

BACKGROUND: Approximately 3.9 million persons worldwide have young-onset dementia. Symptoms related to young-onset dementia present distinct challenges related to finances, employment, and family. To provide tailored support, it is important to gain knowledge about the formal support available for persons with young-onset dementia. Therefore, this paper aims to describe formal support for persons with young-onset dementia in Sweden and the factors influencing this support.
METHODS: This retrospective study used data on persons under 65 years of age (n = 284) from The Swedish Registry for Cognitive/Dementia Disorders (SveDem) between 2021 and 2022. SveDem was established to monitor the quality of dementia care in Sweden. Characteristics of participants were obtained, including age, sex, dementia diagnosis, MMSE, medications, accommodation, and care setting. Descriptive statistics and logistic regression were used to test for associations between participant characteristics and post-diagnostic support.
RESULTS: Information and educational support were usually offered to the person with young-onset dementia (90.1%) and their family (78.9%). Approximately half of the sample were offered contact with a dementia nurse (49.3%), counsellor (51.4%), or needs assessor (47.9%). A minority (28.5%) were offered cognitive aids. Six regression models were conducted based on participant characteristics to predict the likelihood that persons were offered support. Support was not predicted by age, sex, children at home, accommodation, or medications. Lower MMSE scores (p < .05) and home help (p < .05) were significantly associated with offer of a needs assessor. Living together was a significant predictor (p < .01) for information and educational support offered to the family. Care setting significantly predicted (p < .01) an offer of information and educational support for the person and family members, as well as contact with a counsellor.
CONCLUSIONS: This study indicates potential formal support shortages for persons with young-onset dementia in some areas of dementia care. Despite equal support across most characteristics, disparities based on care setting highlight the importance of specialised dementia care. Pre-diagnostic support is minimal, indicating challenges for persons with young-onset dementia to access these services before diagnosis. While our study has identified areas in need of improvement, we recommend further research to understand the changing support needs of those with young-onset dementia.

A diagnosis of young-onset dementia can pose a significant challenge for the clinician. We present a young patient with a very unusual presentation of Dementia with Lewy Bodies. The lack of motor symptoms and his marked apathy delayed his diagnosis. His symptoms were thought to be due to depression based on normal structural imaging and the psychiatric nature of his presentation. An extensive work-up was performed. Evidence of a structural neurodegenerative process was provided by the HMPAO-SPECT. Cardiac MIBG confirmed the diagnosis.

Posterior Cortical Atrophy (PCA) is a rare form of young-onset dementia that causes early visuospatial and visuoperceptual deficits. The symptom profile of Posterior Cortical Atrophy leads to very specific care needs for those affected, who often rely on informal caregivers (including friends and family). Rare dementia support groups can be useful for both patients and their caregivers to assist with knowledge sharing, psychoeducation, and the provision of psychosocial support. Despite this, few such support groups exist. The purpose of this study was to examine a PCA support group for caregivers of individuals living with PCA. We held a structured psychoeducation support group comprised of four sessions with the aim being to provide education, strategies for the management of the disease, and peer support. Caregivers\' mental health and quality of life were assessed. The results of our study showed that support group participation was a positive experience and assisted with increasing the knowledge of caregivers and fostering social connections. We suggest that peer support groups may be beneficial for both people living with PCA and their caregivers. We recommend that future quantitative and qualitative research is conducted to further assess health-promotion benefits to people living with PCA and their caregivers, and to assess their development and implementation in different contexts.
