Background: The Clinical Dementia Rating (CDR) scale allows to detect the presence of dementia and to assess its severity, however its evaluation requires a significant time (45 min). We evaluated the agreement between two methods of collection of the CDR: face-to-face interview or based on the information available in the patient's medical record.
Methods: The CLIMER study was conducted among patients attending a memory center.

Background: The identification of factors involved in the conversion across the different Alzheimer's disease (AD) stages is crucial to prevent or slow the disease progression. We aimed to assess the factors and their combination associated with the conversion across the AD stages, from mild cognitive impairment to dementia, at a mild, moderate or severe stage and to identify profiles associated with earliest/latest conversion across the AD stages.
Methods: In this study conducted on the real-life MEMORA cohort data collected from January 1, 2013, and December 31, 2019, three cohorts were selected depending on the baseline neurocognitive stage from a consecutive sample of patients attending a memory center, aged between 50 and 90 years old, with a diagnosis of AD during the follow-up, and with at least 2 visits at 6 months to 1 year of interval.
Context: Mild neurocognitive disorder (NCD), formally known as mild cognitive impairment, is usually the clinical stage preceding the development of Alzheimer's disease (AD), the most prevalent major NCD, and other causes of dementia. Glucose is a major source of energy for human brain metabolism and the uptake of glucose is reduced in patients with mild NCD, AD, and other NCDs. Unlike glucose, the uptake of ketones remains normal in people with mild NCD and AD, suggesting that the use of ketone bodies may compensate for glucose energy deficiency in patients with mild NCD and AD.

The objective of this study was to measure the association between previous cumulative anticholinergic and sedative drug exposure (Drug Burden Index) and cognitive decline.
Methods: A cohort study (MEMORA cohort) was conducted in a French memory clinic for patients attending a consultation between November 2014 and December 2020, with at least 2 Mini-Mental State Examination (MMSE) measurements (≥ 6 months apart) and available medication data from the local Primary Health Insurance Fund database (n = 1,970).
Background: The association between the pattern of cortical thickness (CT) and executive dysfunction (ED) in mild cognitive impairment (MCI) and subjective cognitive complaints (SCC) is still poorly understood. We aimed to investigate the association between CT and ED in a large French cohort (MEMENTO) of 2323 participants with MCI or SCC.
Methods: All participants with available CT and executive function data (verbal fluency and Trail Making Test [TMT]) were selected (n=1924).
Background: A large proportion of nursing home (NH) residents suffer from dementia and effects of conventional anti-dementia drugs on their health is poorly known. We aimed to investigate the associations between exposure to anti-dementia drugs and mortality among NH residents.
Methods: This retrospective longitudinal observational study involved 329 French NH and the residents admitted in these facilities since 2014 and having major neurocognitive disorder.
Background: In older patients, medication exposure [i.e. polypharmacy, potentially inappropriate medications (PIMs), medications with anticholinergic and/or sedative properties] is a modifiable risk factor associated with cognitive iatrogenic risk and dementia.

This study aimed to investigate the effect of a-tDCS on the learning of an SFTT during multiple MIt sessions. Two groups of 16 healthy young adults participated in three consecutive MIt sessions over 3 days, followed by a retention test 1 week later.

Methods: We included 700 patients in a prospective study and performed exome sequencing. A panel of 28 Mendelian and 6 risk-factor genes was interpreted and returned to patients.

The development of non-pharmacological interventions, including animal-assisted therapy (AAT), is an encouraging method for the care of people with Alzheimer's disease (AD). A single-center, randomized, single-blind, controlled intervention study was proposed to compare immediate well-being measured by a visual analog scale (EVIBE) as primary outcome between the intervention group (AAT combined with cognitive stimulation) and the control group (cognitive stimulation only) in AD patients. Secondary outcomes were explored, such as well-being after intervention (also with the EVIBE), cognitive performance (measured by Alzheimer's Disease Assessment Scale, cognitive part GRECO version), behavioral and psychological symptoms of dementia (with the Neuropsychiatric Inventory Behavioral Scale-Nursing Home Version), current depressive symptomatology (with the 30 items Geriatric Depression Scale [GDS 30]) and anxiety (by the State-Trait Anxiety Inventory).
View Article and Find Full Text PDFBackground: People with dementia (PwD) are known to have more chronic conditions compared to those without dementia, which can impact the clinical presentation of dementia, complicate clinical management and reduce overall quality of life. While primary care providers (PCPs) are integral to dementia care, it is currently unclear how PCPs adapt dementia care practices to account for comorbidities. This scoping review maps recent literature that describes the role for PCPs in the prevention, detection/diagnosis and management of dementia in the context of comorbidities, identifies critical knowledge gaps and proposes potential avenues for future research.

Multicomponent intervention integrating pharmaceutical care has not yet been evaluated while ADRD patients and their caregivers are exposed to high risk of drug-related problems. The PHARMAID study aimed to assess the impact of personalized pharmaceutical care integrated to a psychosocial program on the burden of ADRD caregivers at 18 months.

These recommendations recall the principles of early diagnosis of presbycusis and the means of optimal rehabilitation as soon as the first symptoms appear.
Material And Methods: The recommendations are based on a systematic analysis of the literature carried out by a multidisciplinary group of doctors and audioprosthetists from all over France.
White matter hyperintensities (WMH), frequently seen in older adults, are usually considered vascular lesions, and participate in the vascular contribution to cognitive impairment and dementia. However, emerging evidence highlights the heterogeneity of WMH pathophysiology, suggesting that non-vascular mechanisms could also be involved, notably in Alzheimer's disease (AD). This led to the alternative hypothesis that in AD, part of WMH may be secondary to AD-related processes.

Methods: Three steps:1/ identifying the existing organizations and structures that could be involved in educational care; 2/ identifying the main educational skills of interest for ADRD patients and caregivers; 3/ conducting a survey among these organizations and structures to achieve a mapping proposal of educational care.
Results: Nine organizations and structures, and 29 educational skills of interest were identified for the step 3 survey.
Objective: Regarding older patients, multiple chronic conditions lead to the intake of multiple medications, involving a higher risk of adverse drug events. In older patients with advanced chronic kidney disease, the medication exposure was poorly explored. The aim of this study was to describe the use of potentially inappropriate medications and medications with anticholinergic and sedative properties in older community-dwelling patients with advanced chronic kidney disease.

Objective: The present study investigated the effect of MIP combined with a-tDCS over the primary motor cortex (M1) on the learning of a finger tapping sequence of the non-dominant hand in healthy older adults.
Methods: Thirty participants participated in this double-blind sham-controlled study.
Introduction: Approximately 40% of dementia cases could be delayed or prevented acting on modifiable risk factors including hypertension. However, the mechanisms underlying the hypertension-dementia association are still poorly understood.
Methods: We conducted a cross-sectional analysis in 2048 patients from the MEMENTO cohort, a French multicenter clinic-based study of outpatients with either isolated cognitive complaints or mild cognitive impairment.
