NEURO-COGS: Neurometabolic Mechanisms of Cognitive Training in Schizophrenia

This study will examine brain metabolic and excitatory/inhibitory mechanisms related to cognitive and visual functioning in adults with schizophrenia and healthy control participants. Participants will complete behavioral assessments, cognitive testing, electroencephalography, magnetic resonance imaging, and magnetic resonance spectroscopy assessments. After baseline assessments, participants will be randomly assigned to one of two computerized cognitive training programs: perceptual discrimination training or cognitive control training. Each training program will include approximately 10 hours of training over 2 to 6 weeks. The study will evaluate changes in cognitive and visual task performance, EEG measures, and brain metabolite concentrations before and after cognitive training. Some participants may also complete optional extended baseline assessments before cognitive training.

Minocycline In Neurocognitive Outcomes - Sickle Cell Disease

Sickle cell disease (SCD) is a common, inherited blood disorder that primarily affects people of African Ancestry. It has a lot of complications including neurological complications. The neurological complications of SCD are particularly devastating and lead to cognitive decline even in the absence of overt brain injury. In such cases, it is thought that inflammation in the brain maybe partly responsible for the cognitive decline. The main reasons for this research study are to see 1) how safe and 2) how well minocycline works to try to stop/reverse cognitive decline in people with SCD. People with SCD are at risk for changes in their brain over time that can cause problems with learning, memory, and attention. Part of the reason for this is inflammation within the brain. Minocycline may be able to stop these brain changes by stopping this brain inflammation. Minocycline is a second-generation tetracycline antibiotic that has been shown to both inhibit neuroinflammation and improve cognitive function in a variety of neurodegenerative and psychiatric disorders but has not yet been studied in SCD. We are proposing here, a pilot double-blinded, randomized controlled trial to examine the tolerability and early efficacy of minocycline in adults with SCD at two dosing regimens (200 mg and 300 mg daily) versus placebo over one year. Participants will undergo a neuropsychological exam using the NIH Toolbox Cognition Battery at both study enrollment and exit (after one year) to assess for changes/stability of cognition. Participants will receive monthly phone calls/text messages to assess for adverse events and will be seen every three months for pill counts and routine laboratory monitoring. The primary outcome will be a comparison of adverse events across the two dosing strategies versus placebo. Early evidence for cognitive benefit will also be assessed from the results of the NIH Toolbox.

Milk Fat Globule Membrane-Enhanced RUTF for Children With Severe Acute Malnutrition

The goal of this clinical trial is to test the use of milk fat globule membrane (MFGM) in ready-to-use therapeutic food (RUTF) in children with severe acute malnutrition in Sierra Leone. The main questions it aims to answer are: * Will the inclusion of MFGM in RUTF for 6-59-month-old Sierra Leonean children with severe acute malnutrition improve their neurodevelopment? * Will the inclusion of MFGM in RUTF for 6-59-month-old Sierra Leonean children with severe acute malnutrition reduce its worst consequences: death, hospitalization, and remaining severely malnourished despite treatment? Researchers will compare the MFGM-containing RUTF to standard RUTF, which contains skim milk powder. Participants will: * undergo measurement of length, weight, mid-upper arm circumference, and nutritional edema assessment every two weeks during severe malnutrition treatment * be treated with either MFGM-RUTF or standard RUTF at a dose of 2 sachets per day for up to 12 weeks * undergo neurodevelopmental testing using the Malawi Developmental Assessment Tool at the end of SAM treatment and 6 months later * a subset of participants will undergo blood spot collection and stool sample collection

BioMIND Biospecimen Repository

The purpose of the BBR is to facilitate scientific research by serving as a local and external resource for the distribution of human blood and CSF biospecimens, together with their corresponding clinical data, to internal and external researchers.

Acute Cognitive Changes During Atrial Fibrillation Episodes (AFCOG)

Objectives: * First, to determine if patients with a history of AF have acute measurable changes in cognitive functioning while in an episode of AF. * Second, to collect basic insight into what specific physiologic (blood pressure, pulse oximetry, heart rate, temperature) and pharmacologic (antiarrhythmic medications, rate control medications, anticoagulants, antiplatelet medications, etc.) factors minimize the neurological impact on patients while they are in AF. It is hypothesized that when using a tablet-based cognitive testing software - Cambridge Cognition (specifically to assess executive function, learning and working memory: Rapid Visual Information Processing test, Spatial Working Memory/Spatial Span Task tests, One touch Stockings of Cambridge test, Cambridge Gambling Task, Multitasking Test/Intra-Extra Dimensional Set shift tests) - a significant difference will be noted between how the patients perform while in atrial fibrillation compared to the patients' performance while in normal sinus rhythm.

A Prospective Study of Cognitive Changes in Retired and Late-Career Professional Soccer Players

Repeated head impacts and concussions may be associated with cognitive difficulties and neurodegenerative changes in athletes. Although this association has been studied primarily in contact sports such as boxing and American football, professional football (soccer) players may also be exposed to repetitive head impacts through heading the ball and sustaining concussions. This prospective study aims to evaluate the cognitive impact of repeated concussions in male and female outfield football players, including late-career and retired professional players. Cognitive function will be assessed using neuropsychological tests and questionnaires evaluating attention, concentration, executive functioning, subjective memory complaints, emotion regulation, anxiety, and depression. Multimodal brain magnetic resonance imaging (MRI) will also be performed to characterize brain imaging findings potentially associated with cumulative exposure to repetitive head impacts. The findings may contribute to a better understanding of potential cognitive and neuroimaging abnormalities in football players and inform future long-term monitoring and preventive strategies.

Robot-Assisted Meditation for Older Adults With Cognitive Concerns

While traditional app-based mindfulness meditation programs relying solely on audio guidance have shown potential benefits for older adults, the programs often face challenges such as low engagement. Participants frequently report difficulties in maintaining focus during meditation sessions, which can limit its effectiveness in improving outcomes such as stress reduction and sleep quality. To address these limitations, this study examines whether a haptic robot that provides both tactile and audio guidance can enhance meditation. The robot's expansion and contraction movements help users pace and sustain rhythmic breathing, while gentle vibrations signal phase transitions without disrupting concentration. These haptic features are intended to anchor attention and support a more embodied practice. The study primarily seeks to answer the following questions: Does a haptic enabled meditation intervention reduce perceived stress in older adults living alone with subjective cognitive decline more effectively than an audio only mindfulness meditation guidance provided by a non-moving robot? To what extent does enhanced attentional anchoring mediate the intervention's effect on perceived stress in this population? By addressing these questions, the research aims to determine whether haptic enabled meditation technology can overcome common barriers to mindfulness practice among older adults and serve as an innovative tool to reduce perceived stress, and ultimately improve their sleep quality and physical, emotional, and cognitive well being.

Primary Care Detection of Cognitive Impairment Leveraging Health & Consumer Technologies in Underserved Communities: The MyCog Trial

Our study intends to offer 'real world' evidence of a viable, sustainable means to mobilize primary care via a comprehensive strategy for detecting cognitive impairment and dementias, advancing next steps for referral, and participating in the care planning and management of affected patients and caregivers. We will conduct a clinic-randomized, pragmatic trial testing the effectiveness and fidelity of our NIH Toolbox-derived paradigm to improve early detection and management of cognitive impairment/dementia in primary care settings serving health disparate patient populations.

A Study Evaluating the Efficacy of Xanomeline/Trospium (XT) on Cognitive Impairment After 24 and 52 Weeks of Treatment in Adult Participants With Schizophrenia

Schizophrenia is a long-lasting and serious mental health disorder that affects about 1% of people worldwide. It can cause symptoms such as hallucinations and delusions (called positive symptoms), confused or disorganized thinking, reduced motivation and emotional expression (negative symptoms), difficulties with memory and concentration (cognitive symptoms), and movement problems like restlessness or slowed activity. Current treatments, called antipsychotics, mainly work by blocking dopamine in the brain. These medicines are helpful for hallucinations and delusions, but they do little to improve negative or cognitive symptoms. A new medicine, Xanomeline/Trospium (XT), works differently. It targets a brain system called the muscarinic acetylcholine receptors while limiting side effects elsewhere in the body. Clinical trials have shown that XT reduces psychotic symptoms effectively and is generally well tolerated. The FDA approved XT in 2024 for adults with schizophrenia. Importantly, early results also suggest that XT may help improve thinking and memory (cognition domains), though this has not yet been studied in depth. Most schizophrenia drug studies pay little attention to long-term changes in cognition, often using only short screening tests. This study will be the first to take a deep look at cognitive function over a full year of XT treatment. It will also examine how changes in thinking skills connect with other aspects of life, such as symptom control, daily functioning, and quality of life. By making cognition a central outcome, the study responds to an urgent need in schizophrenia research: moving beyond just controlling hallucinations and delusions toward improving real-world recovery. The results could help shape future treatment strategies and support the idea that cognition should be a core treatment target in schizophrenia.

ME/CFS Brain Fog: Cognitive Rehabilitation Trial

The purpose of this study is to compare two approaches to cognitive rehabilitation in adults with post-viral cognitive syndrome, which resulted in brain fog. All participants will be screened for eligibility prior to participation. Most of the procedures will take place over a phone call or secure telehealth platform (i.e., Zoom). However, participants will be asked to visit UAB on three occasions for blood sample collection and brain imaging (about 2 hours each). Online testing will happen one month before treatment, one day before treatment, one day afterwards, and 6 months afterwards. The study will utilize two different forms of rehabilitation training to improve participants' cognitive ability. Participants will be randomized to one of the two treatment groups. The first treatment approach, known as Constraint-Induced Cognitive Therapy (CICT), will feature (A) web-based computer "games" that trains how quickly individuals process information that they receive through their senses; (B) online training on everyday activities with important cognitive components, (C) procedures designed to transfer improvements in cognition from the treatment setting to everyday life, and (D) a non-invasive form of vagus nerve stimulation, also known as trans-auricular VNS (taVNS). The second approach, known as Brain Fitness Training (BFT), will include (A) web-based computer "games" that train reaction time and eye-hand coordination; (B) in-lab training on relaxation, breathing, healthy nutrition, and healthy sleep, (C) education about how relaxation, breathing, nutrition, and sleep are connected to thinking effectiveness, and (D) taVNS. Approximately 30 hours of training will be conducted over a secure telehealth platform (i.e., Zoom) in the span of two- to four- weeks. A typical CICT session will consist of one hour of gaming, with the bulk of the session being spent on cognitive training of the target behaviors and procedures designed to promote transfer of therapeutic gains to daily life. ta-VNS will be administered for 10 minutes before gaming and in-lab target behavior training. A typical BFT session will consist of one hour of gaming, training on healthy lifestyle behaviors (i.e., healthy sleep, nutrition, and relaxation habits), as well as procedures designed to promote transfer of behavior changes to daily life. Ta-VNS will be administered for 10 minutes before gaming and in-lab target behavior training. Training sessions in both conditions will be scheduled based on participants' availability, with the options for sessions scheduled to be as close as every weekday over 2 weeks or as loosely as every other weekday (i.e., over a 4-week span). If a caregiver is available, they will receive training on how to best support participants in their therapeutic program. After the training ends, both groups will receive 4 follow-up phone calls approximately one week apart to promote integration of the gained skills into everyday life. Outcomes measured will include cognitive processing speed, cognitive function on laboratory tests, and spontaneous performance of everyday activities with important cognitive components in daily life.

Long COVID Brain Fog: Cognitive Rehabilitation Trial

This study will compare two approaches to cognitive rehabilitation in adults with long COVID with persistent, mild to moderate, cognitive impairment. One approach will feature (A) web-based computer "games" that trains how quickly individuals process information that they receive through their senses; (B) in-lab training on everyday activities with important cognitive components, (C) procedures designed to transfer improvements in cognition from the treatment setting to everyday life, and (D) a non-invasive form of vagus nerve stimulation (VNS), i.e., trans-auricular VNS (taVNS). Component B will include work-related tasks. This approach is termed Constraint-Induced Cognitive Therapy (CICT). The other approach will feature (A) web-based computer "games" that train reaction time and eye-hand coordination; (B) in-lab training on relaxation, healthy nutrition, and healthy sleep, (C) procedures designed to promote integration of these lifestyle changes into everyday life, and (D) taVNS. This approach is termed Brain Fitness Training (BFT). A subset of participants, who qualify for and and desire vocational rehabilitation (VR), will receive VR from the Alabama Department of Rehabilitation Services (ADRS) in addition to CICT or BFT. ADRS VR will include career counseling, prescription of on-the-job accommodations, and guidance on return-to-work. Those in the CICT + VR group will also receive on-the-job coaching from a peer mentor for a month after completing training. CICT, with or without VR, will involve 30 hours of training. Ten 3-hour in-lab, face-to-face, therapist-directed sessions will be scheduled. These sessions will feature one hour of gaming; the remainder will be committed to in-lab training on the target behaviors and the procedures designed to promote transfer of therapeutic gains to daily life and improving skills essential to work; the set of the latter procedures is termed the Transfer Package. ta-VNS will administered for 10 minutes before gaming and in-lab target behavior training. To accommodate the demands of participants' other activities, training sessions will be permitted to be scheduled as tightly as every weekday over 2 weeks or as loosely as every other weekday or so over 4 weeks. If a family caregiver is available, they will receive training on how to best support participants in their therapeutic program. After training ends, four follow-up phone calls will be scheduled approximately one-week apart with participants to promote integration of the skills gained during training into everyday life. BFT, with or without VR, will involve 30 hours of training following the same schedule as for CICT. Ten 3-hour in-lab, face-to-face, therapist-directed sessions will be scheduled. These sessions will feature one hour of gaming; the remainder will be committed to in-lab training on the target behaviors (healthy sleep, nutrition and relaxation habits) and the procedures designed to promote transfer of behavior change to daily life. ta-VNS will be administered for 10 minutes before gaming and in-lab target behavior training. If a family caregiver is available, they will receive training on how to best support participants in their therapeutic program. After training ends, four follow-up phone calls will be scheduled approximately one-week apart with participants to promote integration of the skills gained during training into everyday life. Participants will be randomly assigned to the interventions. Randomization will be stratified by whether participants qualify for and desire VR from ADRS or not. If yes, participants will be randomized in equal numbers to CICT + VR or BFT + VR. If no, participants will be randomized in equal numbers to CICT or BFT. Testing will happen one month before treatment, one day before treatment, one day afterwards, and 6-months afterwards. Outcomes measured will include cognitive processing speed, cognitive function on laboratory tests, and spontaneous performance of everyday activities with important cognitive components in daily life. Another important outcome measure will be whether or not participants were able to return back to work or had significant improvements in their work activities.

Finnish Geriatric Intervention Study to Prevent Cognitive Impairment and Disability

This multi-center (6 sites: Helsinki, Kuopio, Oulu, Seinäjoki, Turku, Vantaa) intervention study aims to prevent cognitive impairment, dementia and disability in 60-77 year old persons at an increased dementia risk. The 2-year multi-domain life-style intervention includes nutritional guidance, exercise, cognitive training, increased social activity, and intensive monitoring and management of metabolic and vascular risk factors. The primary outcome is cognitive impairment measured by a sensitive Neuropsychological Test Battery (NTB), and Stroop and Trail Making tests to capture early cognitive impairment typical for both Alzheimer's disease and vascular dementia. We hypothesize that the multi-domain intervention will reduce cognitive impairment in the study group compared to the control group during the initial 2-year intervention period and reduce dementia incidence after the extended follow-up (until at least 300 participants have developed dementia).

Negotiation Training for Family Caregivers of People With Alzheimer's Disease

Family caregivers of people living with Alzheimer's disease and related dementias often experience conflicts and communication challenges when coordinating care, making decisions, and interacting with family members and healthcare providers. These challenges can contribute to caregiver burden, stress, anxiety, and reduced well-being. The purpose of this study is to evaluate the effectiveness of NegotiAge, an online negotiation and communication training program designed for family caregivers. NegotiAge provides education and interactive practice exercises to help caregivers develop negotiation, problem-solving, conflict-resolution, and communication skills that can be applied to real-world caregiving situations. Approximately 200 family caregivers will be randomly assigned to either the NegotiAge intervention or an attention-control educational website. Participants will complete online surveys before the intervention, immediately after the intervention, and at 1-month and 3-month follow-up time-points. The study will examine whether NegotiAge reduces caregiver burden and improves communication, conflict-management behaviors, self-efficacy, stress, anxiety, fatigue, and well-being. Findings from this research may help improve support programs for family caregivers of people living with Alzheimer's disease and related dementias.

EEG Markers From Polysomnography and Cognitive Performance in Obstructive Sleep Apnea

This cross-sectional study examines whether EEG markers derived from full-night polysomnography (sleep spindle density, K-complex density, and REM EEG slowing) are associated with cognitive performance in adults with obstructive sleep apnea, and whether they explain more variance in cognitive test scores than classical OSA metrics (AHI, T90, minimal SpO2).

Adaptation and Normalization of a Verbal Episodic Memory Test in French Sign Language

To date, neuropsychological assessment of deaf signing persons is complicated by a lack of resources, especially the absence of tools available in French Sign Language (LSF). This is due to perceptual and cultural differences, and in particular the linguistic differences between French and LSF. This lack of resources significantly hinders access to care for deaf patients, as neuropsychological assessment is often a key clinical criterion in the diagnosis of certain neurological pathologies (Alzheimer's disease in particular) and enables coherent care plans to be drawn up, for example in the aftermath of strokes or traumatic brain injuries. In particular, episodic memory (which refers to the ability to memorise information anchored in a specific context) is a cognitive domain that is sensitive to pathologies such as Alzheimer's disease, but it is not currently possible to assess it with deaf signing patients. The aim of this study is to create a memory assessment test adapted to a deaf population that expresses in LSF and to normalize this test on this same population. The aim is to provide a diagnosis assessment tool, which currently does not exist in France, to improve access to care for deaf people. This project could then be extended to the creation of tests for other cognitive domains (executive functions, attention, social cognition, etc.) and to prospects for cognitive remediation. The 16-item Free and Cued Recall test (RL-RI 16) is the best choice because it is easy to use and accurate enough to assess each stage of episodic memory. These qualities make it a decisive tool in certain differential diagnosis.

Rhythmic Exercise in Older Adults With Cognitive Impairment

Rhythmic physical exercise is a very promising non-pharmaceutical tool to prevent or reduce cognitive decline that occurs in people sixty years of age or older. The main objective is to determine the effect of a rhythmic exercise program on the physical, mental and cognitive performance of older adults with cognitive impairment. The main variables of the study will be: global cognitive function evaluated by the Mini Mental State Examination (MMSE) and the Montreal Cognitive Assessment (MoCA); attention and executive functions evaluated using the Trail Making Test (TMT) part A and B. As secondary variables, the functional abilities evaluated using the Senior Fitness Test (SFT) will be taken into account. Additionally, sociodemographic variables and variables related to health status will be evaluated. These will take into account the quality of sleep evaluated with the Pittsburgh index, the nutritional status evaluated using the Mini Nutritional Assessment-Short Form (MNA-SF) scale, and the Stress and anxiety levels will be assessed using the Depression Anxiety Stress Scales-21 (DASS-21). All variables will be evaluated before the intervention and after it. After the intervention, it is expected that the exercise program will improve the neurocognitive performance, as well as the functional and psychological abilities of older adults.

PAMNEU - Memory in Neurology

Memory in Neurology project (PAMNEU) aims to map the distribution and severity of cognitive impairment in patients of outpatient neurologic offices across the geographical area of the Czech Republic. 1000 patients in 50 neurologic offices will undergo cognitive tests (ALBA and PICNIR) and psychometric scales (FAQ-CZ and GDS-CZ) to asses their functional state and depressive symptoms. The trial's primary goal is to assess the distribution of cognitive impairment among diagnostic groups in neurologic care according to the ICD-10. Additionally, the feasibility of ALBA and PICNIR methods to uncover previously undiagnosed cognitive impairments will be evaluated.

PAPSY - Memory in Psychiatry

Memory in Psychiatry project (PAPSY) aims to map the distribution and severity of cognitive impairment in patients of outpatient psychiatric offices across the geographical area of the Czech Republic. 1000 patients in 90 psychiatric offices will undergo cognitive tests (ALBA and PICNIR) and psychometric scales (sFAQ-CZ and GDS-CZ) to asses their functional state and depressive symptoms. If applicable, caretakers will also be asked about the extent of the participant's autonomy and behavioral impairment (using oFAQ-CZ and MBI-C-CZ scales). The trial's primary goal is to assess the distribution of cognitive impairment among diagnostic groups in psychiatric care according to the ICD-10. Additionally, the feasibility of ALBA and PICNIR methods to uncover previously undiagnosed cognitive impairments will be evaluated.

Examining the Role of Tolerance on Dose-dependent Effects of Acute THC on Oculomotor and Cognitive Performance

The purpose of this research is to determine the extent to which oculomotor function accurately detects THC-impairment, if cannabis use experience impacts this detection threshold, and to examine how the oculomotor index corresponds to a measure of sustained attention. A double-blind, placebo-controlled, within-subjects crossover design will be used to examine the dose-effects of THC (0, 5mg, 30mg) on oculomotor performance tasks and a sustained attention task in frequent and infrequent cannabis users. Results from the study will advance the investigators' understanding of the effect of THC and cannabis use frequency on oculomotor function and sustained attention, and will directly inform the validity of the investigators' oculomotor platform for identifying acute THC- induced impairment in frequent and infrequent users.

PICS-p Longitudinal Cohort Study

Children who survive critical illness may develop new or worsening problems with physical health, cognitive status, emotional well-being, and social functioning. These problems, collectively known as post-intensive care syndrome in pediatrics (PICS-p), may also affect family well-being. Evidence on how frequently these problems occur, how they change over time, and which factors influence recovery remains limited in China. This single-center, prospective observational cohort study at Children's Hospital of Fudan University aims to describe the occurrence and recovery trajectories of PICS-p and identify factors associated with persistent difficulties or recovery. The study focuses on children admitted to the pediatric intensive care unit (PICU) with sepsis, severe pneumonia or acute respiratory distress syndrome, those receiving cranial neurosurgical care, and those requiring prolonged mechanical ventilation. Clinical information and standardized assessments will be collected to evaluate physical function, overall quality of life, cognitive function, psychological well-being, social functioning, and family outcomes. Follow-up will include assessments at 1, 3, 6, and 12 months after PICU discharge, with longer-term follow-up planned at 2 years, 3 years, and beyond. The study will examine how outcomes change over time and identify potentially modifiable risk factors. The findings will help identify early which children and families need additional support and guide the development of rehabilitation and coordinated follow-up care across hospital, home, and community settings.

Mindfulness-Integrated Neuropsychotherapy for Traumatic Brain Injury: A Mixed-Methods Evaluation of Cognitive and Psychosocial Recovery

The goal of this clinical trial is to test the effectiveness of Integrative Mindfulness Enhanced Neuropsychotherapy (IMENP) in improving neurocognitive functioning and wellbeing among adults aged 18 to 44 years with mild to moderate Traumatic Brain Injury (TBI). The main questions it aims to answer are: * Does IMENP improve neurocognitive functioning in individuals with mild to moderate TBI? * Does IMENP improve quality of life, and reduce depression and fatigue in individuals with mild to moderate TBI? Researchers will compare participants who receive the 16 session IMENP programme to participants on a waitlist control condition to see if IMENP improves cognitive functioning and overall wellbeing. Participants in the experimental group will: Attend 16 sessions of IMENP delivered twice weekly over three months Complete mindfulness practices, cognitive rehabilitation exercises, and emotional regulation techniques during sessions Complete between session homework tasks including expressive writing, mindful activities, and reflective exercises Be assessed on neurocognitive functioning, quality of life, depression, and fatigue at baseline, post intervention, and one month follow up Participants in the waitlist control group will: Receive treatment as usual during the three month intervention period Be assessed at the same time points as the experimental group Receive three introductory IMENP sessions following study completion

Auditory-Cognitive Optimization Care Program for Older Adults With Hearing Loss and Cognitive Impairment

Hearing loss and cognitive impairment are common and interrelated health problems that may affect communication, information processing, attention, psychological well-being, daily functioning, and quality of life. This study aims to develop and evaluate a comorbidity-oriented Auditory-Cognitive Optimization Care Program (A-COP) for individuals with hearing loss and cognitive impairment. The A-COP will be developed based on evidence from a literature review and findings from qualitative research involving individuals with hearing loss and cognitive impairment and their caregivers. The program integrates hearing-related care and cognitive stimulation strategies to address the combined needs associated with hearing and cognitive difficulties. In the intervention phase, participants will be randomly assigned to either the A-COP intervention group or an active control group in a two-arm, parallel-group randomized controlled trial. The study will evaluate changes in cognitive function, hearing and communication-related outcomes, depressive symptoms, and quality of life from baseline through the 6-month follow-up. The findings will provide evidence regarding the effects of the A-COP in individuals with hearing loss and cognitive impairment.

Dyadic Cognitive Intervention for Older Adults With Cognitive Impairment and Their Spouses

The goal of this randomized controlled clinical trial is to learn if a couple-centered cognitive intervention program can improve cognitive health, reduce caregiving burden, and support overall well-being for community-dwelling older adults (aged 60 and above) with mild cognitive impairment and their spouses. The main questions it aims to answer are: * Does the couple-based cognitive intervention improve the cognitive function of older adults with mild cognitive impairment? * Can the intervention reduce the caregiving burden experienced by spouses who care for a partner with cognitive impairment? * Can the intervention help reduce depressive symptoms, improve quality of life, and strengthen the ability of couples to cope with the disease together? Researchers will compare two groups of participants: the intervention group receives the couple-based cognitive program in addition to regular community health education, while the control group receives only regular community health education. The study will test whether the intervention leads to better health and well-being outcomes for both the older adults with cognitive impairment and their spouse caregivers. Participants will: * Be randomly assigned to either the intervention group or the control group * If in the intervention group: join an 8-week structured couple intervention with their spouse. The program covers cognitive health knowledge, joint memory and thinking exercises, communication and coping skill practice, and guidance for shared healthy daily habits * If in the control group: receive standard community health education about cognitive impairment prevention and care * Complete health and well-being assessments at the start of the study, 3 months after the intervention, and 6 months after the intervention. Assessments include tests of cognitive function, daily living ability, mood, quality of life, how well couples cope with the disease together, and how much burden spouses feel from providing day-to-day care.

Brain Boosters 2 in Persons at Risk for Alzheimer's Disease: a Digital Application Supported Intervention

The purpose of this research is to determine if training in memory support aids and healthy lifestyle activities (physical exercise, mentally stimulating activities and stress management) can have a positive effect on memory, thinking, and activities that people do every day. Participation in this study will involve being placed into one of two groups: a Self-Guided Intervention Group or a Structured Intervention Group. Both groups will be asked to attend group sessions in which they will be provided education on memory support strategies and lifestyle changes. The Structured Intervention Group will also be provided with an iPad and a digital application (called EMMA) to track their activity. Study participation involves a 6-month intervention and completing outcome measures at 4 different time points for up to a year.
