Filter by:The goal of this prospective observational research with an 8-year follow-up is to study the cognitive changes in the elderly in YuGarden community, Shanghai, China. The main questions it aims to answer are: - incidence of cognitive impairment in community (converting to mild cognitive impairment or Alzheimer's disease) - to build a predictive model for the progression of cognitive impairment
This is a randomized, double-blind, placebo-controlled, parallel group study. The use of placebo is appropriate to minimize bias related to treatment expectations of the subject, study partner, and site investigator, as well as to changes in the relationship between the subject and study partner that might occur with the initiation of treatment and expectation of improvement in motor symptoms or cognition. Changes in subject/study partner interactions can impact subject mood and might introduce biases that cannot be quantified. The double-blind use of placebo will also prevent bias in the clinical and scientific assessments.
This is a multicenter, longitudinal, prospective observational natural history study of subjects with a molecularly confirmed diagnosis of CMT4J. The study will enroll 20 subjects of any age into a uniform protocol for follow-up and evaluations. Subject visits will occur every 12 months + 4 weeks for up to 2 years.
The aim of this study is to evaluate the correlation between the fat infiltration of the lumbar multifidus muscle and several parameters including the severity of the lumbar foraminal stenosis. The investigators will analyse lumbar MRI of patients previously included in a database of patients suffering from low back pain. Foraminal stenosis, muscle fat infiltration and other imaging lumbar parameters will be studied by 2D and 3D manuel segmentation, semi-automatic segmentation. Correlations between factors influencing the muscle fat infiltration will be studied by univariate and multivariate statistical analysis.
1. Explore the effects of natural plant flavonoids on the positive intervention mechanism of neurotransmitter transmission physiological indicators changes (EEG) in the brain of the study subjects; 2. Investigate the effects of natural plant flavonoids in positively intervening clinical symptoms of the study subjects.

The goal of this First-In-Human (FIH) trial is to learn about safety and PharmacoKinetics (PK) in healthy adult volunteers. The main questions it aims to answer are: - What is the safety of single ascending doses of the FluoroEthylNorMemantine (FENM)? - What is the PK profile of single ascending doses of the FENM in human? - What is the preliminary exploratory time course of Brain Disease Neurotrophic Factor (BDNF) plasmatic levels of single ascending doses of the FENM? Participants will receive one single oral dose of FENM.
Traumatic brain injury (TBI) is an altered brain function caused by an external force, which may annually have 69 million incidence cases all over the world. Increasing evidence suggests that TBI may be a major risk of beta amyloid (Aβ)-associated neurodegenerative disorders, such as Alzheimer's disease, frontotemporal dementia, and Parkinson's disease. Investigations from brain imaging studies revealed that Aβ density maps of TBI patients overlapped with those with Alzheimer's disease, and increased Aβ density not only associated with prolonged TBI duration but also associated with decreased white matter integrity. It has been suggested that the axonal injury and cerebrovascular dysfunction due to TBI may associate with the elevated level of Aβ peptides. The increasing accumulation in Aβ due to TBI may contribute to the initiation of the pathological alterations in neurodegeneration diseases. Recent animal studies suggest that acupuncture may promote regeneration of nerves in injured tissues and reduce the concentration of Aβ in brain. Moreover, recent clinical trials also indicate that acupuncture may improve the vascular cognitive impairment due to cerebral small vessel disease. Thus, acupuncture treatment on TBI may not only be of benefit for the TBI recovery but also act to interrupt the pathological changes in these neurodegenerative diseases.
This study is a prospective observational study, which involves a cohort of 2000 all-sex and all-ethnic people aged 60 years and above with permanent residence in Tianma area, SheMountain Town, Songjiang District (suburban area), Shanghai. Demographic information, neuropsychiatric scale, peripheral blood, APOE genotype, brain MRI, speech information, AV45-PET, FDG-PET, Tau-PET, GLP-1R PET, and cholinergic receptor probe (ASEM) PET were collected and analyzed. Follow-up visits were performed twice a year for 4 visits, and neuropsychiatric scales and biological samples were collected at each follow-up visit to construct a diagnostic model for patients with mild cognitive impairment, or Alzheimer's disease, as well as a predictive model for the progression of cognitive impairment.
The pandemic caused by SARS-CoV-2 infection has led to the emergence of diffuse and heterogeneous persistent symptoms in addition to the well-known acute symptoms, which have come to be referred to as persistent COVID. In particular, one of the frequent complaints of patients with a previous diagnosis of COVID is impaired cognitive ability. Various cognitive rehabilitation programmes have benefited from incorporating the methodology of so-called "serious games" are designed to train or change behaviour while entertaining players. The design of the online rehabilitation programme (COPERIA-COG) took into account the principles of neuropsychological rehabilitation (neuropsychological pre-assessment, operational goal setting, task prioritisation and continuous feedback system) and combined different individual techniques, such as restitution and compensation. Patients treated with COPERIA-COG will show neuropsychological improvements in verbal memory compared to the waiting list group. The main objective is to identify differences in long-term memory in patients treated with COPERIA-COG vs. patients on the waiting list. For this purpose, both groups will be evaluated through RAVLT, taking the long-term memory subtest as a reference, comparing the results before and after the active group performs the online training with COPERIA-COG. The COPERIA platform is a cloud platform that provides a range of ICT tools for monitoring and aiding the recovery of patients with persistent COVID. To achieve this goal, the platform will store patient data to which Artificial Intelligence techniques will be applied to perform an assessment of the affected person.
