Early Detection of Alzheimer's Disease and Affective Disorders by Automated Voice and Speech Analysis (PLATA)

PLATA aims to develop an algorithm to identify vocal biomarkers of Alzheimer's dementia. Using data collected as part of routine care, speech patterns will be compared to known biomarkers of Alzheimer's disease, such as amyloid 1-42 and p-Tau in CSF (cerebrospinal fluid). If biomarkers of speech can be identified in Alzheimer's disease, it is possible that patients and research participants will no longer need to undergo need to undergo the intensive and invasive baseline biomarker methods currently used, such as lumbar punctures and PET scans.

Adapted Physical Activity Education in Patients With Neurocognitive Disorder

This study aims to compare the effect of a program of Adapted Physical Activity (APA) versus the same program combined with a physical activity education program (PAE). Patients suffering from neurocognitive disorders (mild or early major) will be randomized into one of the two conditions. 3 complete evaluations will be done (inclusion M0, after 3 month of intervention M3, 3 months after the end of the intervention M6). The team except that APA+PEA will be more effectiv than the APA solely, on the following criteria : level of physical activity, cogntive function and quality of life.

The Liver Cirrhosis Cognitive Decline Scale (LiCCoS)

The goal of this observational study is to develop and test a new questionnaire called the Liver Cirrhosis Cognitive Decline Scale (LiCCoS) for adults with liver cirrhosis. This questionnaire is designed to help identify problems with thinking and daily mental functioning that are common in people with liver cirrhosis but are often missed during routine care. People with liver cirrhosis may experience problems such as forgetfulness, slowed thinking, trouble paying attention, or difficulty planning everyday tasks. These problems can affect daily life, safety, and treatment adherence. Existing cognitive tests often require special training or equipment and may not fully reflect how people experience these difficulties in daily life. This study aims to create a simple, patient-reported tool that captures these concerns in an easy and practical way. The main questions this study aims to answer are: 1. Can the LiCCoS questionnaire reliably measure cognitive difficulties in adults with liver cirrhosis? 2. Does the questionnaire correctly reflect differences in cognitive function across levels of liver disease severity? 3. Do LiCCoS scores relate to results from commonly used cognitive screening tests? Participants will be adults aged 18 to 75 years who have a confirmed diagnosis of liver cirrhosis and are attending outpatient clinics. Participation is voluntary. Participants will: Provide basic background information, such as age and medical history Complete the LiCCoS questionnaire about their thinking and daily mental functioning Complete standard cognitive screening tests commonly used in clinical care This study does not involve any treatment or change in medical care. The information collected will be used only for research purposes. The results are expected to help develop a reliable and easy-to-use tool that can support early recognition of cognitive difficulties in people with liver cirrhosis and improve communication between participants and health care providers.

Integration of Neurocognitive Biomarkers Into a Neuro-Oncology Clinic

This is prospective observational registry study that will assess 1) if the neurocognitive function app (Brainlab Cognition) can be used in a widespread neuro-oncology clinic setting and 2) if patient reported quality of life parameters can be obtained electronically and integrated into clinic.

Creation of an Ecological Tool Assessing Episodic Memory in Geriatrics

In this study the participants can be recruited via scheduled consultation and external institutions (associations, senior club..). Neuropsychological assessment will be realize to determine presence or absence of neurodegenerative disease. Study test is ecological MAI. This test are assigned in two groups (with or without neurocognitive disorders).

Creatine and Perioperative Brain Health

The goal of this study is to understand the effects of oral creatine supplementation in the perioperative period. Creatine is commonly used to enhance athletic performance, but it can also have positive effects on the brain. Since surgery can lead to alterations in thinking, memory, and attention patterns in some patients, we will assess whether creatine can be protective against these changes in older adults undergoing surgery.

Impact of Lifestyle Interventions on Cognitive Decline in Non-alcoholic Fatty Liver Disease

This study investigates whether a structured lifestyle program can help improve thinking skills and liver health in adults with Non-Alcoholic Fatty Liver Disease (NAFLD). We are enrolling 45 participants, aged 18-42, who will be randomly assigned to one of three groups for six months: one receiving general health advice, a second following a supervised Mediterranean diet plan, and a third combining the same diet with a regular walking program. The main goal is to see if these diet and exercise interventions can lead to better scores on memory and reasoning tests, reduce liver stiffness measured by a painless scan (FibroScan), and improve related blood markers of inflammation and hormone balance.

Efficacy and Safety of Oral Midazolam Used for the Delivery of Care in Elderly Patient With Neurocognitive Disorders and Refusing Care.

The purpose of this study is to assess the effectiveness of oral midazolam on the delivery of care in elderly patients with moderat to severe neurocognitive disorders and opposing care.

Nutrition-based Interventions to Prevent Cognitive Decline

This study intends to evaluate the feasibility and the effectiveness of an innovative and integrated nutrition-based intervention addressing key modifiable risk factors for dementia while meeting participants' preferences for nutrition-related sessions. The intervention will include lifestyle group sessions regarding nutrition education and physical activity, individualized cognitive training at home, as well as clinical nutrition consultations.

Cognitive Outcomes After Dexmedetomidine Sedation in Cardiac Surgery Patients

Anesthesia is a drug induced, reversible, comatose state that facilitates surgery and it is widely assumed that cognition returns to baseline after anesthetics have been eliminated. However, many patients have persistent memory impairment for weeks to months after surgery. Cardiac surgery appears to carry the highest risk of postoperative cognitive dysfunction (POCD). These cognitive deficits are associated with increased mortality, prolonged hospital stay and loss of independence. The investigators propose to investigate the role of Dexmedetomidine (DEX) in preventing long-term POCD after cardiac surgery and enhancing early postoperative recovery. It is anticipated that DEX will be the first effective preventative therapy for POCD, improve patient outcomes, and reduce length of stay and healthcare costs.

Effects of t-DCS and Cognitive Training on Apathy in Elderly With Minor Neurocognitive Impairment

Transcranial direct current stimulation (tDCS) is a non-invasive brain stimulation technique using a low intensity electric current to modify cortical excitability. Apathy is a pervasive neuropsychiatric symptom characterized by a reduction in goal-directed behavior and activity that persists over time and causes identifiable functional impairment. The aim of this study is to evaluate the effects of repeated sessions of tDCS combined with simultaneous cognitive training on apathy in older people with minor neurocognitive disorders.

Interventions for Silent Brain Infarction and Perioperative Neurocognitive Disorders in Cardiovascular Surgery

the purpose of the study is to investigate whether a combined anesthetic targets bundle, known as the NeuroFirst strategy, focused on neurological protection, can reduce the incidence of silent brain infarction (SBI) and perioperative neurocognitive disorders (PND) in patients undergoing cardiac surgery. Additionally, the trial will assess the safety of this strategy. The NeuroFirst target bundle incorporates multiple parameters, including mean arterial pressure (MAP), bispectral index (BIS), regional cerebral oxygen saturation (rSO2), and arterial inflow temperature during cardiopulmonary bypass. The primary question this study seeks to answer is: Does the NeuroFirst strategy reduce the incidence of SBI and PND in cardiac surgery? To address this, researchers will compare the NeuroFirst strategy with routine institutional practices based on published guidelines. Participants will be randomly assigned to either the NeuroFirst group or the routine care group. All participants will undergo magnetic resonance imaging (MRI), be assessed using the Confusion Assessment Method (CAM) and the Montreal Cognitive Assessment (MoCA), and be followed for up to one year postoperatively.

A Study of Different Donanemab (LY3002813) Dosing Regimens in Adults With Early Alzheimer's Disease (TRAILBLAZER-ALZ 6)

This study will investigate different donanemab dosing regimens and their effect on the frequency and severity of ARIA-E in adults with early symptomatic Alzheimer's disease (AD) and explore participant characteristics that might predict risk of ARIA. Approximately 375 additional participants will be enrolled per addendum. The study will last approximately 91 weeks and include up to 26 visits in the main study.

Cognitive Reserve and Response to Speech-Language Intervention in Bilingual Speakers With Primary Progressive Aphasia

Difficulties with speech and language are the first and most notable symptoms of primary progressive aphasia (PPA). While there is evidence that demonstrates positive effects of speech-language treatment for individuals with PPA who only speak one language (monolinguals), there is a significant need for investigating the effects of treatment that is optimized for bilingual speakers with PPA. This stage 2 efficacy clinical trial seeks to establish the effects of culturally and linguistically tailored speech-language interventions administered to bilingual individuals with PPA. The overall aim of the intervention component of this study is to establish the relationships between the bilingual experience (e.g., how often each language is used, how "strong" each language is) and treatment response of bilinguals with PPA. Specifically, the investigators will evaluate the benefits of tailored speech-language intervention administered in both languages to bilingual individuals with PPA (60 individuals will be recruited). The investigators will conduct an assessment before treatment, after treatment and at two follow-ups (6 and 12-months post-treatment) in both languages. When possible, a structural scan of the brain (magnetic resonance image) will be collected before treatment in order to identify if brain regions implicated in bilingualism are associated with response to treatment. In addition to the intervention described herein, 30 bilingual individuals with PPA will be recruited to complete behavioral cognitive-linguistic testing and will not receive intervention. Results will provide important knowledge about the neural mechanisms of language re-learning and will address how specific characteristics of bilingualism influence cognitive reserve and linguistic resilience in PPA.

Evaluation of the Link Between Carotid Arterial Wall Viscosity and Major Neurocognitive Disorders

The mechanical behavior of conductance arteries is viscoelastic. While the elastic component has been extensively studied, the viscous component has often been neglected for methodological reasons and also because it was considered weak. Unlike a purely elastic solid, which exhibits instantaneous deformation/relaxation upon application/discontinuation of a force, a viscoelastic solid is characterized, from a mechanical point of view, by a delay between the application or discontinuation of the force and deformation. Thus, at the arterial level, the elasticity of the arterial wall allows the internal diameter to increase proportionally to the blood pressure during systole. The viscous component will induce a delay in diameter restoration, resulting in a larger diameter at each pressure level during the diastolic phase compared to the systolic phase. This results in a shift between the systolic and diastolic curves of the pressure-diameter relationship, creating a hysteresis loop. From a thermodynamic point of view, while a purely elastic material fully restores the energy stored during the loading phase, viscoelastic arteries will incompletely restore this energy. Thus, the surface of the hysteresis loop reflects the energy dissipated during each cardiac cycle (WV), and the area under the loading phase curve represents the energy stored by the arterial wall (WE) during the latter. Thus, arterial wall viscosity (APV) can be expressed either as the absolute value of WV or as a function of the stored energy (WV/WE). Physiologically, this energy loss is low. Its increase could be accompanied by excessive energy dissipation, leading to increased cardiac work and cardio-circulatory decoupling. Conversely, low parietal viscosity could lead to damage to peripheral organs by excessive transmission of pulsatile energy to the periphery due to lack of damping.

Biobank and Brain Health in Bordeaux.

B cube is a new generation cohort to study the determinants and natural history of brain aging, using molecular epidemiology, in a representative sample (N=2000) of the general population from the age of 55 (the approximate age of onset of the first cognitive disorders and a target population particularly receptive to prevention messages). Special interest will be given to nutrition, a promising environmental exposure for prevention.

Cognitive Disorders and Brain Pulse

Following an initial consultation with a memory, resources and research centre (MRRC) doctor, a day hospital may be prescribed to carry out an assessment of cognitive disorders. Patients are then usually followed up in consultation at least once a year, in the framework of a new day hospital and/or consultations with a MRRC doctor.

Integration of Health Information Technology and Promotion of Personhood in Family-Centered Dementia Care

Alzheimer's disease and related dementias (ADRD) are leading causes of disability and often result in communication deficits of the person with dementia (PWD) that can complicate ADRD caregiving and clinical care. The research team will work with stakeholders to develop and design a personalized Assistive and Alternative Communication (AAC) device that relies on information technology (IT) and touchscreens to promote communication and personhood for PWD about their care preferences and experiences. This study will integrate the AAC into an existing health IT intervention that already facilitates clinical communication between caregivers and providers of PWD. A clinical trial will be conducted to evaluate outcomes of 58 dyads (PWD/caregivers) and their health care provider utilizing the My PATI (My Person Assisted Touchscreen Interface)intervention as an adjunct to care and care giving for 6 months.

rTMS for Apathy Clinical Trial

Apathy is a common, early, and disabling symptom in dementias and mild behavioural impairment such as Alzheimer's disease (AD) and is characterized by lack of interest and enthusiasm. Both repetitive transcranial magnetic stimulation (rTMS), a form of non-invasive brain stimulation, and methylphenidate, a medication, have been shown to improve apathy. This pilot study will investigate rTMS as a treatment for apathy in neurocognitive disorders and mild behavioural impairment in individuals receiving methylphenidate and individuals not receiving medication for apathy.
