To evaluate the effectiveness of the SPAN-intervention, a psychosocial intervention aiming at improving a sense of usefulness and engaging in meaningful activities, for community-dwelling people living with young-onset dementia (YOD) and their family caregivers. A cluster-randomized controlled trial with two parallel groups (SPAN-intervention vs. care as usual) with assessments at baseline and five-month follow-up was performed. Sixty-one persons living with YOD and their family caregivers were included (SPAN-intervention group: n = 35; care as usual group: n = 26). Outcomes included, for the person living with YOD, empowerment (operationalized by self-management abilities using the SMAS-30; primary outcome), quality of life, neuropsychiatric symptoms, disability, apathy; and, for the family caregiver, quality of life, emotional distress, sense of competence. Data were analyzed using linear mixed models. We found no statistically significant effects of the SPAN-intervention on empowerment, nor on the secondary outcome measures for persons living with YOD or their family caregivers. Although the SPAN-intervention may provide concrete opportunities to engage in activities and stimulate reciprocity, such as meaningful social activities, this study did not demonstrate intervention effects. Additional qualitative evaluations may provide more insight into the implementation process and experiences of people living with YOD and their family caregivers. This trial was registered at ClinicalTrials.gov (NCT02937883). [ABSTRACT FROM AUTHOR]

Background: The evidence underpinning palliative care in dementia is mostly based on research in older populations. Little is known about the palliative care needs of people with young-onset dementia (YOD). Objective: To describe palliative care practices including advance care planning (ACP) in people with YOD residing in Dutch nursing homes. Methods: The study presents baseline questionnaire data from an observational cohort study. Physicians, family caregivers, and nursing staff completed questionnaires about 185 residents with YOD. The questionnaires included items on sociodemographics, quality of life measured with the quality of life in late-stage dementia (QUALID) scale, dementia-related somatic health problems, symptoms, pain medication, psychotropic drugs, and ACP. Results: The mean age was 63.9 (SD 5.8) years. Half (50.3%) of them were female. Alzheimer's disease dementia (42.2%) was the most prevalent subtype. The mean QUALID score was 24.0 (SD 7.9) as assessed by family caregivers, and 25.3 (SD 8.6) as assessed by the nursing staff. Swallowing problems were the most prevalent dementia-related health problem (11.4%). Agitation was often reported by physicians (42.0%) and nursing staff (40.5%). Psychotropics were prescribed frequently (72.3%). A minority had written advance directives (5.4%) or documentation on treatment preferences by the former general practitioner (27.2%). Global care goals most often focused on comfort (73.9%). Proportions of do-not-treat orders were higher than do-treat orders for all interventions except for hospitalization and antibiotics. Conclusions: ACP must be initiated earlier, before nursing home admission. A palliative approach seems appropriate even though residents are relatively young and experience few dementia-related health problems. [ABSTRACT FROM AUTHOR]

The disease trajectory and healthcare requirements of patients with young‐onset dementia (YOD) differ from those of older patients. Accurate data about YOD is crucial to improve diagnosis and optimize care. PRECODE‐GP aims to set up a prospective national database of patients with YOD to gain insight into the occurrence and characteristics of patients with YOD in memory clinics in the Netherlands. The national database includes data from dementia patients aged <70 years at diagnosis, collected by local memory clinics (MCs). Data included demographic information, clinical variables, and (etiological) diagnoses. Between July 2019 and December 2022, 781 patients with a mean age of 62±6y at diagnosis (range 37 to 69y) were included from 39 MCs. Most (n = 547,70%) were diagnosed with dementia due to Alzheimer's disease (AD). Patients with Frontotemporal lobe dementia (FTD, n = 87, 11%) were youngest (61±6.0y). Over half (55%) of patients were experiencing symptoms for ≥2 years. We initiated a Dutch national YOD database to improve diagnosis and care for this underrepresented and vulnerable patient group. The database provides a basis for future in‐depth studies on YOD. [ABSTRACT FROM AUTHOR]

The aim of this study was to describe the course of psychotropic drug use in people with young-onset dementia and to explore possible associations with age, sex, dementia severity, dementia subtype and neuropsychiatric symptoms. Psychotropic drug use was studied in 198 community-dwelling persons participating in the Needs in Young-onset Dementia study. Data about psychotropic drug use were retrieved at baseline, as well as at 6, 12, 18 and 24 months and was classified into five groups (antiepileptics, antipsychotics, anxiolytics, hypnotics/sedatives and antidepressants) and quantified as 'present' or 'absent'. Generalized Estimating Equation modeling and chi-square tests were used to study associations between the determinants and psychotropic drug use. There was a statistically significant increase in the prevalence of psychotropic drug use from 52.3% to 62.6% during the course of the study. Almost three-quarters (72.4%) of the participants were treated with any psychotropic drug during the study, and more than one-third (37.4%) received psychotropic drugs continuously. Antipsychotics were used continuously in more than 10% of the participants and antidepressants in more than 25%. Increasing age was positively associated (p =.018) with psychotropic drug use at baseline, while apathy symptoms were negatively associated (p =.018). Despite the recommendations of various guidelines, the prolonged use of psychotropic drugs in community-dwelling people with young-onset dementia is high. Therefore, more attention is needed to timely evaluate psychotropic drug use and the introduction of self-management programs for caregivers should be encouraged to support caregivers in dealing with the neuropsychiatric symptoms caused by the dementia.

Objective: To evaluate the cost-consequences of an intervention for the management of neuropsychiatric symptoms in nursing home residents with young-onset dementia.Methods: A stepped wedge design was used. The intervention consisted of an educational program and a multidisciplinary care program and was implemented in 13 nursing homes from September 2015 to March 2017. Costs' outcomes included the time investment of the elderly care physician and health care psychologists regarding the management of neuropsychiatric symptoms, residents' psychotropic drug use, nursing staff absenteeism, and costs of the educational program. Composite cost measure contained the sum of costs of staff absenteeism, costs on psychotropic drugs, and costs of the educational program. Costs of time investment were investigated by comparing means. Costs of psychotropic drug use were analyzed with mixed models at resident level and as part of the composite cost measure on unit level. Staff absenteeism was also analyzed at unit level.Results: Compared with care as usual, the mean costs of time invested decreased with €36.79 for the elderly care physician but increased with €46.05 for the health care psychologist in the intervention condition. Mixed model analysis showed no effect of the intervention compared with care as usual on the costs of psychotropic drug use, staff absenteeism, and the composite cost measure. The costs of the educational program were on average €174.13 per resident.Conclusion: The intervention did not result in increased costs compared with care as usual. Other aspects, such as the lack of a structured working method, should be taken into account when considering implementation of the intervention. [ABSTRACT FROM AUTHOR]

Objective: The effect of an intervention on neuropsychiatric symptoms (NPS), particularly agitation and aggression, and psychotropic drug use (PDU) in institutionalized people with young-onset dementia (YOD) was evaluated.Methods: A randomized controlled trial was conducted using a stepped wedge design. Thirteen YOD special care units were randomly assigned to three groups, which received the intervention at different time points. Four assessments took place every 6 months during a period of 18 months. Two hundred seventy-four people with YOD who resided in YOD special care units participated, of whom 131 took part in all assessments. The intervention consisted of an educational program combined with a care program, which structured the multidisciplinary process of managing NPS. The care program included the following five steps: evaluation of psychotropic drug prescription, detection, analysis, treatment, and evaluation of treatment of NPS. The Cohen-Mansfield Agitation Inventory and the Neuropsychiatric Inventory-Nursing Home version were used to assess NPS. Data on PDU were retrieved from residents' medical files. Multilevel models were used to evaluate the effect of the intervention, which accounted for clustering of measurements in clients within units.Results: No significant differences were found in agitation, aggression, other NPS, or PDU after crossing over to the intervention condition.Conclusion: We found no evidence that the intervention for management of NPS in nursing home residents with YOD was more effective in reducing agitation, aggression, other NPS, or PDU compared with care as usual.

Objective: The aims of the current study are (1) to explore the differences in neuropsychiatric symptoms (NPS) between young-onset dementia (YOD) and late-onset dementia (LOD), and (2) to investigate whether the possible differences can be attributed to differences in dementia subtype, gender, psychotropic drug use (PDU), or dementia severity. Method: Three hundred and eighty-six nursing home (NH) residents with YOD and 350 with LOD were included. Multilevel modeling was used to compare NPS between the groups. Furthermore, dementia subtype, gender, PDU, and dementia severity were added to the crude multilevel models to investigate whether the possible differences in NPS could be attributed to these characteristics. Results: Higher levels of apathy were found in NH residents with YOD. After the characteristics were added to the models, also lower levels of verbally agitated behaviors were found in YOD. Conclusion: We recommend that special attention be paid to interventions targeting apathy in YOD. Although no differences in other NPS were found, the PDU rates were higher in YOD, suggesting that the threshold for the use of PDU in the management of NPS is lower. This underscores the need for appropriate attention to non-pharmacological interventions for the management of NPS in YOD. [ABSTRACT FROM AUTHOR]

Aims: The aims of this study are to (1) explore the determinants of quality of life (QoL) in nursing home residents with young-onset dementia (YOD), (2) investigate whether there are differences between dementia subtypes (Alzheimer dementia, vascular/mixed dementia, frontotemporal dementia, other) regarding these determinants, and (3) compare QoL profiles of YOD nursing home residents across dementia subtypes. Methods: This cross-sectional study included 207 nursing home residents. Multilevel modeling was used to determine the relationships between QoL and neuropsychiatric symptoms (NPS), dementia severity, psychotropic drug use (PDU), dementia subtype, age, and gender. Additional multilevel models were used to compare aspects of QoL between dementia subtypes. Results: Residents' QoL was negatively associated with advanced dementia, PDU, and NPS. In general, the relationships between the determinants and QoL were similar across the dementia subtypes. Aspects of QoL differed by dementia subtype. Residents with frontotemporal dementia showed less negative emotions, accepted more help and experienced better quality of relationships with professional caregivers, had a more positive self-image, felt more comfortable in the nursing home environment, and experienced lower quality of social relationships. Conclusions: Considering the high rates of NPS and PDU in YOD residents and their negative associations with QoL, we recommend emphasizing services to manage and reduce NPS and PDU in nursing home residents with YOD. Furthermore, our findings suggest accounting for differences in aspects of QoL by dementia subtype to address specific needs and thereby improve QoL. [ABSTRACT FROM AUTHOR]

Background:Young-onset dementia (YOD) is defined as dementia that develops before the age of 65 years. The prevalence and type of neuropsychiatric symptoms (NPS) in YOD differ from patients with late onset dementia. NPS in dementia patients are often treated with psychotropic drugs. The aim of this study was to investigate psychotropic drug use (PDU) in Dutch community-dwelling YOD patients and the association between age, gender, dementia etiology and severity, symptoms of depression, disease awareness, unmet needs, and type of NPS.Methods:Psychotropic drug use in 196 YOD patients was registered. Drugs were categorized according to the Anatomical Therapeutical Chemical classification. The association between age, gender, dementia type, dementia stage, type of NPS, depressive symptoms, disease awareness, and amount of unmet needs on total PDU was analyzed using binomial logistic regression analysis.Results:Fifty-two percent of the patients were prescribed at least one psychotropic drug; 36.2% of patients used one drug, and 12.2% used two different drugs. Antidepressants (36.2%) and antipsychotic drugs (17.3%) were the most frequently prescribed psychotropic drugs. Anti-dementia drugs were prescribed in 51.5% of the patients. Increasing age and moderate to severe depressive symptoms were positively associated with the total use of psychotropic drugs.Conclusions:Community-dwelling YOD patients have a high prevalence of PDU. More research is needed to study the association between unmet needs, NPS, and PDU, and psychosocial interventions have to be developed to limit the use of psychotropic drugs in YOD.

The article presents a study aimed at proving that the number of unmet needs in young-onset dementia (YOD) is related to both patient and caregiver health-related quality of life (HRQOL). Topics discussed include HRQOL in YOD patients and likely differences with caregiver views on patient HRQOL, HRQOL in YOD caregivers compared with the general population, and the link between unmet needs and both patient and caregiver HRQOL in YOD.

Background: People with young-onset dementia (YOD) living in nursing homes may experience poor quality of life (QoL) due to advanced dementia, high prevalence of neuropsychiatric symptoms and psychotropic drug use. However, the course of QoL in institutionalized people with YOD and factors that predict this course are unclear. This knowledge could help health professionals identify appropriate interventions to improve QoL in YOD. Objective: To explore the course of QoL in institutionalized people with YOD and resident-related predictors of that course. Methods: Secondary analyses were conducted with longitudinal data from the Behavior and Evolution in Young-ONset Dementia (BEYOND)-II study. A total of 278 people with YOD were recruited from 13 YOD special care units in the Netherlands. QoL was measured by the proxy assessment of Quality of Life in Dementia (QUALIDEM) questionnaire at four assessments over 18 months. Independent variables included age, gender, dementia subtype, length of stay, dementia severity, neuropsychiatric symptoms and psychotropic drug use at baseline. Multilevel modeling adjusted for correlation within nursing homes and residents was used to determine the course and predictors of QoL. Results: The total QUALIDEM score (range: 0–111) decreased over 18 months with a statistically significant decline of 0.73 points per six months. A significant increase of QoL over time was seen in the subscales "Care relationship", "Positive self-image", and "Feeling at home". However, a significant decline was observed in the subscales "Positive affect", "Social relations", and "Something to do". Residents' course of QoL was positively associated with the baseline scores of the QoL, age and longer duration of stay; however, being male, having advanced dementia, Alzheimer's disease and high rates of neuropsychiatric symptoms at baseline were negatively associated with the course of QoL Conclusion: Longitudinal changes in QoL in residents with YOD were small over 18 months and QUALIDEM subscales showed multidirectional changes. The largest QoL decline in the subscale "Positive affect" suggests that interventions should be targeted to improve positive emotions, in particular for male residents with neuropsychiatric symptoms and advanced dementia.

Background: It is unknown whether there are differences between young-onset dementia and late-onset dementia in awareness levels and whether awareness is differentially associated with affective symptoms in both groups. The present study assesses possible differences between young-onset (YO-AD) and late-onset Alzheimer disease (LO-AD) in awareness levels and the association between awareness and affective symptoms. Methods: This study included 142 YO-AD and 126 LO-AD patients and their caregivers from 2 prospective studies. The participants were assessed 3 times during 1 year. Awareness was assessed using the Guidelines for the Rating of Awareness Deficits, and affective symptoms were assessed using the anxiety and depression items of the Neuropsychiatric Inventory. Population-averaged logistic regressions were used to analyze awareness and its association with affective symptoms. Results: The odds for impaired awareness in LO-AD were more than double the odds in YO-AD. Intact awareness was associated with depressive symptoms but not with anxiety. This effect was more pronounced in YO-AD compared with LO-AD at baseline. High awareness at baseline did not predict incident affective symptoms. Conclusions: Caregivers and clinicians should be prepared for affective symptoms in YO-AD patients with high awareness. The higher awareness in the YO-AD group also has potential positive implications for this group. [ABSTRACT FROM AUTHOR]

Neuropsychiatric symptoms are common in nursing home residents with young-onset dementia and burdensome for nursing staff. It is known that neuropsychiatric symptoms are associated with burn-out complaints and low job satisfaction. An intervention aimed at decreasing neuropsychiatric symptoms in nursing home residents with young-onset dementia might also result in less burnout complaints and job demands and improve job satisfaction in nursing staff. The aim was to evaluate the effect of the intervention on nursing staff burnout, job satisfaction and job demands. Cluster randomised controlled trial using a stepped wedge design with a total duration of 18 months, with four assessments. Thirteen young-onset dementia special care units across the Netherlands were, by means of random allocation software, assigned to three groups crossing over at different time points. All nursing staff, in total 391, were invited to participate. 305 nursing staff participated during the course of the study of whom 71 participated in all assessments. An educational program followed by a structured multidisciplinary care program aimed at the management of neuropsychiatric symptoms. The care program consists of evaluation of psychotropic drug prescription followed by detection, analysis, treatment and evaluation of treatment of neuropsychiatric symptoms. Emotional exhaustion, depersonalisation and personal accomplishment were assessed with the Utrecht Burnout Scale. Job satisfaction and job demands were assessed with subscales of the Leiden Quality of Work Questionnaire. The baseline burnout risk on emotional exhaustion and personal accomplishment was average, and low on depersonalisation. The mean scores for job satisfaction were above average and for job demands average. Linear mixed models showed that the intervention had no effect on emotional exhaustion (estimated effect −0.04, 95% confidence interval −1.25 to 1.16), depersonalisation (estimated effect 0.24, 95% confidence interval −0.26 to 0.74), personal accomplishment (estimated effect −0.82, 95% confidence interval −1.86 to 0.22) job satisfaction (estimated effect −0.40, 95% confidence interval −0.98 to 0.17) and job demands (estimated effect −0.04, 95% confidence interval −0.57 to 0.49). A significant difference was found between registered nurses and other nursing staff on emotional exhaustion and job satisfaction. Compared to other staff members, registered nurses' emotional exhaustion scores slightly increased while job satisfaction slightly decreased when using the intervention. The intervention was not effective on three dimensions of burnout, job satisfaction and job demands. Staff scored positive on the outcomes of interest before implementation of the intervention, leaving little opportunity for improvement. [ABSTRACT FROM AUTHOR]

Objectives A process evaluation was performed for an intervention aimed at improvement of the management of neuropsychiatric symptoms in young-onset dementia. Data about sample quality and intervention quality was evaluated to better understand internal and external validity. In addition, data about the implementation strategy and factors affecting implementation were evaluated to improve further implementation of the intervention. Design A model proposed by Leontjevas and colleagues consisting of first-order (validity) and second-order (implementation) data was used. Setting and Participants Care units delivering specialized treatment and support for residents with young-onset dementia. Measures A description of the recruitment, randomization procedure, and intervention reach was carried out to determine sample quality. To determine intervention quality, data on satisfaction, relevance, feasibility, and fidelity were collected through a questionnaire and reports logged on the server of the web-based intervention. A description of the implementation strategy was provided. Barriers and facilitators for implementation were collected by a questionnaire and analyzed by deductive content analysis. Results Care units varied in size and were recruited from different geographical regions in the Netherlands. The informed consent rate of the residents was 87.7%. The majority of the nursing home staff were satisfied with the intervention. However, parts of the intervention were perceived as less relevant for their own organization. The feasibility of the intervention was considered low. The fidelity differed between care units. The implementation strategy did not overcome all barriers. Factors affecting implementation covered 3 themes: organizational aspects, culture of the organization, and aspects of the intervention. Conclusions In general, our results showed sufficient internal and external validity, warranting further effect analyses. Adaptations to specific steps of the care program should be considered to increase feasibility and sustainability. In addition, integration of the care program into the electronic health records is expected to further improve implementation. [ABSTRACT FROM AUTHOR]

Objective The aims of this study were (1) to investigate the relationship between different neuropsychiatric symptoms (NPS) and the level of distress experienced by nurses caring for residents with young-onset dementia (YOD) and (2) to compare these findings with those for nurses caring for residents with late-onset dementia (LOD). Design/Setting This is a retrospective study conducted in Dutch long-term care facilities. Data were used from the Behavior and Evolution of Young-ONset Dementia studies (BEYOND) Parts I and II and the WAAL Behavior in Dementia-II (Waalbed-II) study. Participants A total of 382 nursing home residents with YOD and 261 nursing home residents with LOD were included. Measurements The Neuropsychiatric Inventory, nursing home version, was used to assess nursing staff distress and the frequency (F) and severity (S) of NPS. Multilevel logistic regression analysis was used to investigate the relationships between nursing staff distress related to NPS and YOD and LOD care units, the F × S score per symptom, gender, dementia subtype, and dementia severity. Results Nurses working in YOD care units rated sleep and nighttime behavior disorders, delusions, and agitation/aggression most often as highly distressing and euphoria most often as not distressing. Multivariate analyses indicated that the frequency and severity of NPS were significantly associated with staff distress in all symptoms, except for apathy. Comparison of the 2 groups of nurses demonstrated that the odds for distress related to sleep and nighttime behavior disorders were higher for nurses in YOD care units than for nurses in LOD units. For both the YOD and LOD nurses, irritability in male residents had higher impact than similar behavior in female residents. Conclusion This study provides important insight into distress related to individual NPS and the interaction with residents' characteristics. All NPS result in distress. The frequency and severity of the behavior is an important predictor. Sleep and nighttime behavior disorders are more likely to result in distress in YOD nurses than in LOD nurses. The amount of distress related to NPS emphasizes the urgent need for adequate management of NPS and the support of professional caregivers. [ABSTRACT FROM AUTHOR]

Objectives With the lack of a cure for Alzheimer disease (AD), the identification of comorbidity is important to reduce the possibility of excess disability. Although comorbidity in patients with late-onset AD (LO-AD) is common, for people with young-onset AD (YO-AD), it is unclear how often comorbidity occurs. Furthermore, it is uncertain whether comorbidity in patients with YO-AD differs from that in patients with LO-AD. The aim of this study was to explore the prevalence, types of morbidity, and morbidity profiles in patients with YO-AD compared with those of patients with LO-AD. Design Explorative cohort study from 2 separate Dutch cohorts (Needs in Young-onset Dementia [NeedYD] and the Clinical Course of Cognition and Comorbidity–Dementia Study [4C-Dementia study]). Setting Participants were recruited in 2007 and 2008 from (1) the memory clinics of 3 Dutch Alzheimer centers, (2) the memory clinics of general hospitals, (3) mental health services in the southern part of the Netherlands, and (4) young-onset dementia specialized day care facilities. A comparison group of community-dwelling, elderly patients with AD was selected from the 4C-Dementia study. Patients in this study were recruited in 2010 and 2011 from the aforementioned Alzheimer centers. Measurements The prevalence rates of comorbidity were compared between 177 patients with YO-AD and 155 patients with LO-AD. Comorbidity was classified using the International Classification of Diseases, 10th Revision (ICD-10). The total amount of comorbidity was established by counting the number of existing diseases (ICD categories or chapters) and comorbidity was also dichotomized as present or absent. Furthermore, a hierarchical cluster analysis was performed to study clusters of comorbidity. Results Compared with LO-AD, patients with YO-AD showed less ( P < .001) overall comorbidity (58.2% vs 86.5%) and had lower prevalence rates of diabetes, obesity, and circulatory diseases; however, the prevalence rates of diseases of the nervous system in YO-AD (6.2%) were higher compared with those of patients with LO-AD (4.5%). The cluster analysis revealed a distinctive group of patients with YO-AD with either no comorbidity or with a disease of the nervous system. Endocrine, nutritional, and metabolic diseases and diseases of the circulatory system were present in 34% of the patients with YO-AD. Conclusion Comorbidity is less common in YO-AD than in LO-AD. However, general practitioners should be aware that approximately one-third of the patients with YO-AD suffer from or have endocrine, nutritional, and metabolic diseases and/or diseases of the circulatory system. Treatment should therefore not only focus on dementia but also on comorbidity. This attention may slow the functional decline in AD. These exploratory analyses suggested a higher prevalence of nervous system diseases in YO-AD compared with LO-AD. However, the finding did not reach statistical significance and in combination with the exploratory nature of the analyses justifies further investigation. If verified, this finding may help to decrease the time to diagnosis of AD and, subsequently, support in young patients with a neurological disease. Further investigation is needed to gain more insight into the association between comorbidity and AD in younger people. [ABSTRACT FROM AUTHOR]

To explore the course of quality of life (QoL) and possible resident-related predictors associated with this course in institutionalized people with young-onset dementia (YOD). An observational longitudinal study. A total of 278 residents with YOD were recruited from 13 YOD special care units in the Netherlands. Secondary analyses were conducted with longitudinal data from the Behavior and Evolution in Young-ONset Dementia (BEYOND)-II study. QoL was assessed with proxy ratings, using the Quality of Life in Dementia (QUALIDEM) questionnaire at 4 assessment points over 18 months. Predictors included age, gender, dementia subtype, length of stay, dementia severity, neuropsychiatric symptoms, and psychotropic drug use at baseline. Multilevel modeling was used to adjust for the correlation of measurements within residents and clustering of residents within nursing homes. The total QUALIDEM score (range: 0-111) decreased over 18 months with a small change of 0.65 (95% confidence interval −1.27, −0.04) points per 6 months. An increase in several domains of QoL regarding care relationship, positive self-image, and feeling at home was seen over time, whereas a decline was observed in the subscales positive affect, social relations, and having something to do. Residents with higher levels of QoL and more advanced dementia at baseline showed a more progressive decline in QoL over time. Sensitivity analyses indicated a more progressive decline in QoL for residents who died during the follow-up. This study shows that although overall QoL in nursing home residents with YOD was relatively stable over 18 months, there were multidirectional changes in the QoL subscales that could be clinically relevant. Higher levels of QoL and more advanced stages of dementia at baseline predicted a more progressive decline in QoL over time. More longitudinal studies are needed to verify factors influencing QoL in YOD. [ABSTRACT FROM AUTHOR]
