As the prevalence of this disease continues to grow, the current model for Alzheimer's disease diagnosis and patient management will need to evolve to integrate care across clinical disciplines and the disease continuum, beginning with primary care. This review summarizes the importance of establishing an early diagnosis of Alzheimer's disease, related practical 'how-to' guidance and considerations, and tools that can be used by healthcare providers throughout the diagnostic journey.
Alzheimer's Disease is the most common cause of dementia, affecting memory, thinking and behavior. Selleck BI-2493 Symptoms eventually grow severe enough to interfere with daily tasks. AD is predicted to increase healthcare spending and costs associated with formal and informal caregiving. The aim of this study was to identify and quantify the contribution of the different cost components associated with AD.
A structured literature review was conducted to identify studies reporting the economic burden of Alzheimer`s Disease beyond the healthcare setting. The search was conducted in Medline, Embase and EconLit and limited to studies published in the last 10 years. For each identified cost component, frequency weighted mean costs were calculated across countries to estimate the percentage contribution of each component by care setting and disease severity. Results obtained by each costing approach were also compared.
For community-dwelling adults, the percentage of healthcare, social care and indirect costs to total costs were 13.9%, 17.4% and 68.7%, respectively. The percentage of costs varied by disease severity with 26.0% and 10.4% of costs spent on healthcare for mild and severe disease, respectively. The proportion of total spending on indirect costs changed from 60.7% to 72.5% as disease progressed. For those in residential care, the contribution of each cost component was similar between moderate and severe disease. Social care accounted on average for 85.9% of total costs.
The contribution of healthcare costs to the overall burden was not negligible; but was generally exceeded by social and informal care costs.

Alzheimer's disease and related diseases (ADRD) are a major cause of health-related cost increase.
This study aimed to estimate the real medical direct costs of care of patients followed at a memory center, and to investigate potential associations between patients' characteristics and costs.
Cross-sectional analyses conducted on matched data between clinical data of a cohort of patients and the claims database of the French Primary Health Insurance Fund.
Memory center in France.
Patients attending a memory center with subjective cognitive complaint.
Medical or nonmedical direct costs (transportation) reimbursed by the French health insurance during the one year after the first memory visit, and socio-demographic, clinical, cognitive, functional, and behavioral characteristics were analyzed.
Among 2,746 patients (mean ± SD age 79.9 ± 8 years, 42.4% of patients with dementia), the total direct cost was on average € 9,885 per patient during the year after the first memory visit € 7,897 for patienttients with NCD impact direct costs of care.
Higher real medical direct costs were independently associated with cognitive, functional, and behavioral impairment, diabetes mellitus, anxiety disorders, number of drugs, etiologies as well as caregiver burden in patients attending a memory center. The identification of factors associated to higher direct costs of care offers additional direct targets to evaluate how interventions conducted in patients with NCD impact direct costs of care.
This study aimed to investigate the associations between secondhand smoke exposure and dementia, Alzheimer's disease (AD) and stroke.
This prospective study analyzed Framingham Offspring (FHS-OS) cohort participants with parents in the original Framingham Heart Study (FHS) cohort with known smoking status during offspring childhood. Surveillance for incident events, including dementia and stroke, among offspring participants exposed to parental smoking up to the age of 18 years commenced at examination 9 through 2014 and continued for approximately 30 years.
At baseline, a total of 1683 (56.2%) subjects were not exposed to any secondhand smoke, whereas 670 (22.4%) subjects were exposed to 0-1 packs (20 cigarettes)/day, and 640 (21.4%) were exposed to over 1 pack/day. On follow-up (median 31 years), 2993 patients developed dementia, including 103 with AD dementia and 315 with stroke. After adjusting for a wide range of established risk factors, participants with the highest exposure to secondhand smoke exhibited increased risks of all dementia, AD dementia and stroke compared with individuals with no exposure [HR 2.86 (2.00-4.09) for dementia; HR 3.13 (1.80-5.42) for AD dementia; HR 1.89 (1.37-2.61) for stroke]. The results remained comparable in the subgroup for individuals with median exposure to secondhand smoke.
Exposure to secondhand smoke may be associated with increased risks of dementia, AD dementia and stroke.

Mild cognitive impairment (MCI) is a critical pre-dementia target for preventive interventions. There are few brief screening tools based on self-reported personal lifestyle and health-related information for predicting MCI that have been validated for their generalizability and utility in primary care and community settings.
To develop and validate a MCI risk prediction index, and evaluate its field application in a pilot community intervention trial project.
Two independent population-based cohorts in the Singapore Longitudinal Ageing Study (SLAS). We used SLAS1 as a development cohort to construct the risk assessment instrument, and SLA2 as a validation cohort to verify its generalizability.
community-based screening and lifestyle intervention Participants (1) SLAS1 cognitively normal (CN) aged ≥55 years with average 3 years (N=1601); (2) SLAS2 cohort (N=3051) with average 4 years of follow up. (3) 437 participants in a pilot community intervention project.
The risk index indicators included age, female sex, years of schooling, hearing loss, depression, life satisfaction, number of cardio-metabolic risk factors (wide waist circumference, pre-diabetes or diabetes, hypertension, dyslipidemia).
