Designing the next-generation clinical care pathway for Alzheimer's disease.

The reconceptualization of Alzheimer's disease (AD) as a clinical and biological construct has facilitated the development of biomarker-guided, pathway-based targeted therapies, many of which have reached late-stage development with the near-term potential to enter global clinical practice. These medical advances mark an unprecedented paradigm shift and requires an optimized global framework for clinical care pathways for AD. In this Perspective, we describe the blueprint for transitioning from the current, clinical symptom-focused and inherently late-stage diagnosis and management of AD to the next-generation pathway that incorporates biomarker-guided and digitally facilitated decision-making algorithms for risk stratification, early detection, timely diagnosis, and preventative or therapeutic interventions. We address critical and high-priority challenges, propose evidence-based strategic solutions, and emphasize that the perspectives of affected individuals and care partners need to be considered and integrated.

The burden of caring for dementia patients: caregiver reports from a cross-sectional hospital-based study in China.

The impact of dementia care on caregivers' professional, personal, emotional and social well-being was measured in a cohort of 1,387 caregivers in seven regions across mainland China, using a Chinese version of the Zarit Burden Interview (ZBI) and four supplementary questions. Caregivers also estimated costs of care and medical resource utilization. Caregiver burden was generally low to moderate. Dementia care had the greatest impact on caregivers' professional lives, with 25.5% reporting a reduced work schedule in the past month. Lost work time was greater for caregivers of patients with previously diagnosed dementia than for those with newly diagnosed dementia. Average monthly out-of-pocket costs of dementia care exceeded national average monthly incomes of rural and urban residents. These findings highlight the obstacles facing the country with the fastest-growing elderly population in the world.

Clinical Characterization and the Caregiver Burden of Dementia in China.

OBJECTIVES: The prevalence of dementia in China is among the highest in the world, but systematic estimates of the rate of dementia subtypes and characterization of associated deficits are lacking. The primary aim of this study was to determine the clinical presentation of dementia and describe the caregiver burden in mainland China. METHODS: A 3-month, open-enrollment, multicenter, cross-sectional study was conducted at 48 tier-3 hospitals. Caregivers who qualified for study entry (provided amount and duration of care information), had intimate knowledge of patient status, and accompanied enrolled patients to study sites were asked to participate in an interview about patient care and caregiver burden. Caregiver burden was assessed via the Chinese version of the validated Zarit Burden Interview. RESULTS: A total of 1425 caregivers completed the survey. Patients had mild to moderate dementia (mean Clinical Dementia Rating score of 1.67±0.79), and the most common dementia subtypes were Alzheimer disease (46.7%) and vascular dementia (28.7%). Among caregivers, 57% were females, 52% were patients' spouses, and 67.3% had been caring for patients for 1 year or more. Most patients required family help and lived at home or with a family member. Caregiver awareness of dementia was limited. The mean total caregiver Zarit Burden Interview score was 26.6. Observations were similar across age, gender, education, dementia type, Clinical Dementia Rating score, and duration of care. CONCLUSIONS: China faces multiple obstacles in preparing to care for its fast-growing dementia population. Better understanding of patients and caregivers may mitigate these challenges by improving awareness and education.
