Creatine Β· Exercise Β· Mild Cognitive Impairment (MCI)
The goal of this 26-week trial is to learn if creatine supplementation and resistance training (i.e., weightlifting; exercise that increases muscle mass), alone and together, impact cognition, brain health, and physical function in older adults with mild cognitive impairment. Previous studies have shown that resistance training improves cognition and brain health in older adults. Creatine is naturally occurring in the human body and is known to decline with age. Studies have shown that creatine increases muscle mass and bone density in older adults when supplemented. Some research has suggested that creatine may also improve cognition and brain health. However, little is known about how creatine supplementation affects the aging brain and body alone and when combined with resistance training, especially in those with known cognitive impairment. In this study, participants will be randomly assigned to one of four groups: 1) creatine and resistance training, 2) placebo and resistance training, 3) creatine and active control (balance and tone classes), or 4) placebo and active control. Participants in the creatine groups will take creatine every day during the study. Participants in the placebo groups will take a look-alike substance that contains no drug every day during the study. Participants in the resistance training groups will attend three 60-minute classes per week that target each major muscle group and will increase in difficulty during the study. Participants in the active control group will attend three 60-minute classes per week that will consist of balance, stretching, and range of motion exercises. This group accounts for variables such as physical training received by traveling to the training centres, social interaction, and changes in lifestyle secondary to study participation. Researchers will collect information before and after the 26 weeks to see if creatine supplementation and/or resistance training have any effects on cognition, brain health, and/or physical function. The investigators suspect that both creatine supplementation and resistance training will improve cognition, brain health, and physical function alone. However, it is thought that the combination of creatine supplementation and resistance training will improve cognition, brain health, and physical function more.
Mild Cognitive Impairment Β· Cognitive Dysfunction
Normal ageing presents subtle cognitive changes that can be detected before meeting the criteria for Mild cognitive impairment (MCI). Older people with low cognitive reserve and who receive limited cognitive stimulation are at greater risk of deterioration. In this regard, cognitive stimulation (CS) has been identified as an intervention that reduces this risk, provided that its design considers the differences in the level of cognitive reserve (CR) acquired throughout life and the baseline level of cognitive functioning. The general objective of this study is to evaluate, through a randomized clinical trial, the effectiveness of a computerized cognitive stimulation program, designed and adapted from Occupational Therapy based on the level of cognitive reserve in older adults in Primary Care. 100 participants will be randomized in a stratified manner according to the level of cognitive reserve (high/low), assigning 50 participants to the control group and 50 participants to the intervention group. The intervention group will carry out a computerized cognitive stimulation intervention designed and adapted from occupational therapy according to the level of cognitive reserve, through the "stimulus" platform. The main result expected to be achieved is the improvement of higher brain functions. As secondary results, the investigators expect that those cognitive aspects most vulnerable to ageing will decrease more slowly (in areas such as memory, executive function, attention and processing speed) and that the cognitive reserve of the participants will increase, in addition to being able to balance gender differences in these aspects. The investigators think that these results can positively impact the creation of adapted, meaningful and stimulating CS programs in older adults to prevent MCI and experience healthier ageing.
Alzheimer's Disease Β· Biomarkers Β· Non-invasive Diagnosis
The biological diagnosis of AD is actually performed by analysing AΞ²1-40 and AΞ²1-42 peptides, total tau and tau phosphorylated at Thr181 (p-Tau181) from cerebrospinal fluid (CSF) samples obtained by lumbar puncture (LP). Phospho-Tau 217 (p-Tau217) is a new biomarker that could be measured in plasma. The aim of this study is to compare the performances of plasma p-Tau217 with those of the reference CSF biomarkers in 150 patients recruited in the memory center of CHU Amiens (France). The study will be conducted during 18 months. The inclusion will be proposed to all patients for whom an indication of lumbar puncture / CSF is raised in a context of clinical suspicion of AD. During the daily hospitalization during which CSF will be collected for the "classical" biomarkers testing, a single tube of blood will be collected (anticoagulant EDTA, collected for p-Tau 217 analysis). The performances of CSF and plasma pTau 217 will be compared with the clinical diagnosis of AD (+, -, or indeterminate).

Dementia Β· Neurodegenerative Diseases Β· Alzheimer Disease
Hyperspectral retinal imaging is a non-invasive imaging modality in which a series of images of the retina are captured using light of different wavelengths. The resulting "hypercube" of data provides a wealth of information about the retinal structure. Our group has developed evidence supporting a role for this technology in the detection of retinal amyloid beta in Alzheimer's disease. We are undertaking further studies to establish the role of this method in the assessment of people with dementia, or those at risk of Alzheimer's disease. In addition, we wish to test whether the approach may have value in other forms of dementia or neurodegenerative disease such as Parkinson's disease, Lewy-Body dementia or vascular dementia.

Alzheimer Disease Β· Alzheimer Disease With Delusions Β· Alzheimer Disease With Psychosis
This research project aims to understand the brain mechanisms behind the manifestation of psychotic symptoms in AlzheimerΒ΄s disease (AD), and nature of the unique relationship with tau pathology. Amongst the cognitive manifestations of psychosis are impairments related to frontal circuits (social cognition, working memory and executive function deficits). The investigator's previous work suggests a role of tau pathology (one of the hallmarks of AD neuropathology) in the manifestation of psychosis in AD. However, the cerebral mechanisms that underly this association remain poorly understood. The overarching aim of the study is is to investigate the mechanisms by which tau network pathology may promote the presentation of psychosis in AD.
Dementia Β· Mild Cognitive Impairment
Dementia is a global public health challenge with a heavy caregiving burden, impacting families, communities, and healthcare systems. It is a priority in healthcare planning, with focus on early diagnosis and ongoing support. This research project addresses the global public health challenge posed by dementia, focusing on early detection and comprehensive care. The research evaluates the clinical, social, and healthcare impact of two dementia-related projects in Italy: 1. the first "Ricor-Dare," aims to create an integrated network for identifying new cases of dementia or Mild Cognitive Impairment (MCI) and providing care to patients and caregivers; 2. the second involves establishing a new Center for Cognitive Disorders and Dementia (CCDD) in an area previously lacking such services. The primary goal of this study is to assess the effectiveness of case-finding strategies promoted by the "Ricor-Dare" project for the early detection of cognitive decline. Researchers will compare three different settings in which case-finding will be conducted: at the general practitioners' offices, at the Dementia Operations Center, and at Open Days for the general population. The aim is to measure how many individuals in these three settings are diagnosed with Mild Cognitive Impairment (MCI) or dementia, compared to those identified as potential cases through cognitive testing. The secondary goal of the study is to assess the social, care, and prevention impact of the activities offered within the two projects. This includes evaluating the experiences of patients and families who access the new CCDD in the province of Pavia, the impact of care pathways on caregivers, and comparing the effectiveness of the new CCDD with existing ones in the region of Lombardia. The study will also assess the role of the "Ricor-Dare" project in addressing the needs of patients, caregivers, and professionals, as well as the effectiveness of awareness-raising and training activities on dementia. Overall, the study aims to provide valuable insights into improving care for people with dementia and supporting their families and caregivers.

A prospective and retrospective cohort study of about five years will be performed on blood and cerebrospinal fluid samples taken for diagnostic reasons from recruited patients within the Neuromed Neurology Unit. Subjects with other chronic neurodegenerative diseases such as Amyotrophic lateral sclerosis (ALS), Alzheimer's disease (AD) and Parkinson's disease (PD), and healthy subjects subjected to blood sampling and / or lumbar puncture for clinical reasons will be recruited As control groups.
Alzheimer Disease Β· Physical Activity
The goal of this clinical trial is to test the benefits of beat-accented music stimulation (BMS) for behavioral changes of physical activity (PA) in older adults with subjective memory complaints. Specific Aims are to determine (1) whether BMS beneficially influences PA behaviors and psychological responses to PA in older adults for 6 months, and (2) whether exercising with BMS differently influences physical and cognitive functioning as well as quality of life in older adults. To test the effects of BMS on PA, participants will be randomly assigned to an exercise intervention that either includes BMS or does not include BMS. Participants will attend a supervised group strength training (ST) (30 minutes per day) and aerobic exercise (AE) (30-50 minutes per day) session for 3 days per week for the first 2 months, 1 day per week for the next 2 months (while encouraging participants to independently perform both AE and ST on other days), and independently for the final 2 months (always with a goal of performing \>150minutes per week AE and 3 days per week of ST for 30 minutes per day).
