Filter by:This is a cross-sectional and longitudinal study to establish diagnostic models based on olfactory function assessments and odor-induced brain activation for cognitive impairment in patients with type 2 diabetes mellitus.
The overall objective of this study is to compare the overall pattern of [18F]APN-1607 uptake in subjects with MCI, subjects with AD dementia, and healthy subjects.
Cognitive deficit is a core symptom of schizophrenia (SZ), but its pathological mechanism is poorly understood and the treatment effect is poor. The excitatory-inhibitory microcircuit (E-I) function imbalance formed by inhibitory interneurons and excitatory pyramidal cells in the cerebral cortex is a new mechanism of cognitive deficits in SZ discovered in recent years. Cortical E-I is expected to be a new target for the treatment of cognitive deficits in SZ. Paired transcranial magnetic stimulation (ppTMS)-induced intracortical inhibition (ICI) is dependent on cortical E-I functional integrity. We found that ICI deficiency is stable in SZ and is closely related to cognitive function. Therefore, ICI is likely to be a system-level biomarker for cognitive deficits caused by E-I imbalance. However, no study has yet explored the genetic basis of ICI and its impact on the occurrence, development and treatment response of cognitive deficits in SZ. Based on this, we intend to verify the value of ppTMS-induced ICI as a biomarker of E-I imbalance in SZ patients and normal controls at different stages: 1. To explore the correlation of ICI with multidimensional cognitive deficits and E-I pathway genes; 2. To explore ICI Combining candidate genes and serum inflammatory factors can predict whether TMS can improve the efficacy of cognitive deficits, and can be used for precise treatment of SZ cognitive deficits at the level of pathological mechanisms.
This randomized controlled trial aims to evaluate the effectiveness of Tai Chi and conventional exercise on improving cognitive function in older adults with mild cognitive impairment (MCI). Participants will be randomized into three six-month programmes, namely Health Education group, Tai Chi group and Conventional Exercise group. Assessments will be conducted at baseline, after the 26-week interventions, and 26-week after the competition of the intervention.
It is a prospective interventional randomized controlled single center trial. The goal of the trial is to evaluate the efficacy of smart soup on cognition, behavior, biomarkers and safety in Alzheimer's disease (aMCI and dementia).
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. The present study has the objective of validating a digital method for detection and follow-up of patients with mild cognitive impairment (MCI) or dementia in a memory clinic setting.
This study will conduct a group randomized trial to test the effects of a hula-based intervention in improving vascular risk factors for ADRD and cognitive complaints and function over 12 months.
This is a multicenter pilot randomized controlled trial, with an active control condition, of the feasibility, acceptability, and preliminary efficacy of EndeavorRx in a cohort of survivors of acute lymphoblastic leukemia or brain tumor ages 8-16 who are > 1 year from the end of therapy.
This study is a randomized controlled trial (RCT) of a remotely-delivered, technology-assisted psychotherapy program, supported by an innovative software platform for people with cognitive impairment experiencing anxiety.
Cognitive impairment related to dementia is frequently under-diagnosed in primary care settings. This problem is more prevalent in health disparities populations. The investigators developed the 5-Cog brief cognitive assessment that is simple to use, standardized, takes <5 minutes, does not require informants, and accounts for major technical, cultural, and logistical barriers of current assessments. The investigators propose a hybrid Type 1 effectiveness-implementation design in real-world settings to adapt and test the effectiveness of the 5-Cog paradigm to increase detection of cognitive impairment care in older adults presenting with cognitive concerns. The study aim is to evaluate, using a pragmatic cluster-randomized trial design, the effectiveness of the 5-Cog paradigm to increase 'incident cognitive impairment' detection (new MCI and dementia diagnoses) relative to enhanced usual care in 6,600 older patients presenting with cognitive concerns in 22 primary care clinics in Bronx and Indiana. As diagnosis without action will not improve patient care, 'improved dementia care' will be examined as a secondary outcome. Results will also be examined in NIH designated health disparity populations including underserved minority and socio-economically challenged populations.
