Alzheimer's disease (AD) is a progressive neurodegenerative disorder characterized by cognitive decline, including impairments in orientation, memory, and daily functioning. Orientation dysfunction, involving difficulties in recognizing time, place, and person, is a common and clinically significant feature in patients with mild to moderate AD. This study aims to evaluate the effectiveness of a scenario-based reenactment training program in improving cognitive function and orientation ability in patients with mild to moderate Alzheimer's disease. The intervention is based on patients' real-life experiences and uses personalized visual materials (e.g., photos and videos) to reconstruct familiar scenarios, thereby enhancing cognitive stimulation and environmental recognition. In this prospective controlled study, participants will be assigned to either a scenario-based training group or a usual care group. The intervention group will receive structured training sessions three times per week for 3 months, followed by a 6-month follow-up period. The control group will receive standard care without structured cognitive training. The primary outcome is global cognitive function assessed by the Montreal Cognitive Assessment (MoCA). Secondary outcomes include orientation function, depressive symptoms, anxiety levels, quality of life, and intervention feasibility. This study aims to provide evidence for a practical, non-pharmacological intervention to improve cognitive and functional outcomes in patients with Alzheimer's disease.
NCT07549074
The research aims to investigate the effectiveness of a new short-term multicomponent intervention to promote the bio-psycho-social-spiritual health of older adults with MCI to improve their cognitive abilities. In this study, the multicomponent intervention consists of healthy lifestyle psychoeducation and cognitive stimulation. This study is a double-blind, clustered, randomized, controlled, four-arm parallel group study. 200 eligible older adults with MCI are openly recruited into activity groups in local elderly centres. The activity groups are randomly allocated to three intervention groups (i.e., multicomponent intervention, cognitive stimulation and lifestyle psychoeducation) and a control group in a 1:1:1:1 ratio. The participants with MCI are blinded on group allocation and kept uninformed which type of intervention they are receiving. An investigator, blinded to group allocation and intervention, assess outcomes using standardized assessment tools before and after the intervention and after 3 months.
NCT03839784
The research team is creating a foundational infrastructure in order to develop a precision medicine approach for geriatric patients who require surgery with anesthesia. The team plans to build the first of its kind comprehensive database of demographic and risk factor questionnaire responses, biobanked blood specimens, intraoperative electroencephalography (EEG), and inclusive cognitive testing throughout patient interaction starting at the preop appointment until a year later. This will be used to create a predictive model of periooperative neurocognitive disorders.
NCT04246164
The primary objective of this project is to assess the feasibility of multi-field, extended HD-tDCS (MFE-HD-tDCS) with simultaneous computerized CT as a viable intervention to improve cognitive function in patients with MCI. This double-blinded, randomized pilot clinical trial of repetitive daily HD-tDCS/sham HD-tDCS, administered in combination with CT to subjects with MCI in 3 monthly blocks of 5 daily sessions for a total of 15 sessions will enroll 8 participants.

NCT04100057
Recent findings suggest that sleep disruption may contribute to the generation and maintenance of neuropsychiatric symptoms including anxiety, depression, agitation, irritation, and apathy while treating sleep disruption reduces these symptoms. Impairments in the neural systems that support emotion regulation may represent one causal mechanism mediating the relationship between sleep and emotional distress. However, this model has not yet been formally tested within a sample of individuals with or at risk for developing Alzheimer's Disease (AD) This proposal aims to test a mechanistic model in which sleep disturbance contributes to neuropsychiatric symptoms through impairments in fronto-limbic emotion regulation function in a sample of individuals at risk for developing, or at an early stage of AD. This study seeks to delineate the causal association between sleep disruption, fronto-limbic emotion regulation brain function, and neuropsychiatric symptoms. These aims will be achieved through a mechanistic, randomized 2-arm controlled trial design. 150 adults experiencing sleep disturbances and who also have cognitive impairment with the presence of at least mild neuropsychiatric symptoms will be randomized to receive either a sleep manipulation (Cognitive Behavioral Therapy for Insomnia CBT-I; n=75) or an active control (n=75). CBT-I improves sleep patterns through a combination of sleep restriction, stimulus control, mindfulness training, cognitive therapy targeting dysfunctional beliefs about sleep, and sleep hygiene education. Neuropsychiatric symptoms, fronto-limbic functioning, and sleep disruption will be assessed at baseline and at the end of the sleep manipulation through functional Magnetic Resonance Imaging (fMRI), clinical interviews, PSG recordings, and self-report questionnaires. Neuropsychiatric symptoms (anxiety and depression) and sleep disturbance (actigraphy, Insomnia Severity Index, and sleep diaries) will be assayed at baseline and each week throughout the sleep manipulation to assess week-to-week changes following an increasing number of CBT-I sessions. Wristwatch actigraphy will be acquired from baseline to the end of the sleep manipulation at week 11. Neuropsychiatric symptoms and sleep will be assessed again at six months post-manipulation.

NCT03536975
Our main goal is to test a web platform accessible by computers, smartphones and tablets, addressed specifically to caregivers and people with mild cognitive deterioration or mild to moderate dementia providing added value services based on social networks, adapted interventions, clinic strategies and gamification to improve the quality of life of caregivers and people living with dementia (dyads) and permitting to leave in the community as long as possible. To evaluate the platform effectiveness and impact in dementia type disease affected people and caregivers a randomized, controlled, parallel, longitudinal is proposed. The objective will be to assess during 18 months aspects related to health of individuals (general aspect of health, neuropsychological, daily living functionalities, quality of life, treatment adherence, comorbidities ...), social aspects (improving dyad relationship…) and economics (cost-effectiveness of platform utilization), as well as satisfaction degree and usability of platform.
NCT07533084
The goal of this experimental multicentric intervention study is to validate, in Italian, the dynamic Neurocognitive Adaptation (dNA) Scale, which has already been validated in English, among a healthy elderly population (aged 65 and older) residing in Italy and patients with dementia or Alzheimer's Disease. dNA is a questionnaire designed to assess both current and past levels of engagement in physical, cognitive, creative, and social activities. Neuropsychological data, subjective measures, and MRI data will be collected and analyzed to address the following research questions: 1. Is there a positive correlation between scores on the dNA Scale and cognitive efficiency, as reflected in neuropsychological measures, such as episodic memory and executive functions? 2. Is there a correlation between dNA scores and improved functional connectivity within neural networks, such as the Default Network (DN)? The study aims to recruit a total of 265 participants with mild cognitive impairment, subjective memory complaints, or dementia. These participants will be distributed among the 8 recruitment centers; the data collected will then be sent to the designated centers for behavioral data analysis and neuroimaging analysis. Participants recruited at the participating clinical centers will undergo: * A clinical interview, during which demographic and medical history information will be collected. The dNA Scale will be administered, along with a questionnaire assessing adherence to dietary habits typical of a Mediterranean diet (14-ItemMediterranean Diet Adherence Screener; MEDAS). * A neuropsychological assessment, aimed at evaluating general cognitive function with a particular focus on episodic memory and executive functions. The following tests will be administered: Mini-Mental State Examination (MMSE) or, alternatively, Montreal Cognitive Assessment (MoCA); Rey Auditory Verbal Learning Test (RAVLT); Trial Making Test (TMT) Form B; Digit Span Forward and Backward (WAIS or WAIS-III); and the Stroop Test. These measures will provide both a global cognitive assessment (MMSE, MoCA) and more specific measures of memory and executive functioning. * Self-report questionnaires designed to assess depressive symptoms using the Geriatric Depression Scale (GDS) and anxiety symptoms using the Geriatric Anxiety Scale (GAS) (or alternatively the State-Trait Anxiety Inventory, STAI). Finally, the Cognitive Reserve Index Questionnaire will be administered to estimate Cognitive Reserve (CRIq). * Where available, MRI data previously acquired for clinical or diagnostic purposes will be included in the study and analyzed by the principal investigator.
NCT07529015
The goal of this clinical trial is to determine whether acoustic stimulation during sleep can enhance slow-wave sleep (SWS), improve cognitive function, and reduce AD-related pathology in individuals with mild cognitive impairment (MCI), compared with cognitively healthy participants. The main questions it aims to answer are: 1. Does acoustic stimulation increase SWS (e.g., slow oscillation and sleep spindle activity) in individuals with MCI? 2. Does enhancing SWS lead to improvements in memory and cognitive performance? 3. Does acoustic stimulation influence plasma p-tau217 levels as a marker of underlying Alzheimer's disease pathology? Researchers will compare participants receiving acoustic stimulation during sleep with those not receiving stimulation to evaluate its effects on sleep architecture, cognition, and plasma biomarkers. Participants will: * Undergo sleep recordings to assess sleep architecture, including SWS, slow oscillations, and sleep spindles * Receive acoustic stimulation during sleep across multiple nights * Complete cognitive assessments, particularly memory-related tasks * Provide blood samples to measure plasma p-tau217 levels * Provide clinical and demographic information for analysis

NCT05896332
Alcohol misuse is a risk factor for early onset cognitive impairment, contributing to 10% of early onset dementia, with risk corresponding to consumption. Additionally, continued drinking risks worsening cognitive decline and dementia progression, while worsening cognitive impairment contributes to drinking escalation. Repetitive transcranial magnetic stimulation (rTMS) has been shown to improve cognition in Alzheimer's Disease and Related Dimentias (ADRD) and separately reduce heavy drinking in alcohol use disorder. Our objective is to optimize rTMS for simultaneous mitigation of both drinking and cognitive dysfunction in older adults.

This goal of this study is to measure how much insulin the device delivers to the cerebrospinal fluid (CSF). In addition, this study will look at the effects of insulin administered intra-nasally on memory, and on blood levels of insulin.
NCT05380297
Dementia, especially dementia caused by Alzheimer's disease, is considered one of the most severe health problems of our time. It is currently known that the disease begins many years before clinical symptoms appear. The sooner the patient is diagnosed, the sooner the patient will be in a position to prevent further deterioration. A recent orientation is the analysis of language in relation to the description of images with a high and varied semantic and emotional content. It can be studied that changes in the description of an image check if these changes are associated with the evolution of a person with probable impairment both in memory and cognitive as well as emotional, psychiatric, behavioral and even in their interaction with environmental factors especially those associated with socialization and loneliness. Thus, the purpose of this study is to validate speech analysis AI models.
