Filter by:Severe fatigue, depression, sleep problems and cognitive impairment are the most commonly reported side effects of cancer treatment. These aversive side effects are hypothesized to be related to the disruption of circadian rhythms associated with cancer and its treatment. Exposure to Bright White Light (BWL) has been found to synchronize the circadian activity rhythms but research with cancer patients has been scarce. Therefore, the proposed randomized control trial (RCT) will test if systematic light exposure (sLE) will minimize overall levels of cancer-related fatigue (CRF), depression, sleep problems and cognitive impairment among breast cancer patients undergoing breast cancer treatment (i.e., surgery, chemotherapy). SLE incorporates the delivery of harmless UV-protected BWL or Dim White Light (DWL - standard comparison in light studies) delivered to patients by using special glasses for 30 minutes each morning, during their treatment. The proposed study, including a delineated comparison condition, will investigate the effects of BWL on CRF, sleep, depression, cognition, circadian rhythms, and inflammation markers among patients undergoing breast cancer treatment. The proposed RCT could have major public health relevance as it will determine if an easy-to-deliver, inexpensive, and low patient burden intervention reduces common side effects (e.g., CRF, depression, cognitive impairment) of cancer treatment (i.e., surgery, chemotherapy). Aim 1 - Assess whether Bright White Light (BWL) compared with Dim White Light (DWL) among breast cancer patients undergoing breast cancer treatment will minimize overall levels of CRF, depression, sleep problems, and cognitive impairment during and after breast cancer treatment, compared to healthy controls. Aim 2 - Determine whether the BWL intervention affects cortisol rhythms, circadian activity rhythms, melatonin rhythms, and inflammation markers that have been identified as correlates/causes of cancer-related side effects (e.g., CRF, depression, sleep problems). Aim 3 - Exploratory: Explore whether the effects of BWL compared to DWL on the cancer-related side effects (e.g., CRF, cognitive impairment) are mediated by the beneficial effects of the BWL in synchronizing circadian rhythms. Aim 4 - Exploratory: Explore potential moderators of the intervention including seasonality, chronobiology, personality, and social factors.
Emerging evidence indicates that circadian rhythms may be disrupted following cancer and its treatment, and that circadian rhythm disruption may be an underlying pathophysiological mechanism of cancer- and cancer treatment-related symptoms (CRS) such as fatigue, sleep disturbance, cognitive impairment, and depressed mood. Given the detrimental effect of CRS on cancer survivors' quality of life, and a pressing demand for effective interventions to treat CRS, there is a need for a comprehensive examination of circadian disruption related to cancer and its treatment, and its association with CRS. The study will prospectively examine circadian rhythms and a CRS composite score in recently diagnosed breast cancer patients from prior to surgery or chemotherapy to 12 months later. A matched healthy control group will serve as a comparison.

And explore the clinical and molecular parameter for predicting severe cognitive impairment induced by WBRT and gaining benefit from GM1. Primary Endpoint: the change of Hopkins Verbal and Learning Test-Revised Delayed Recall,HVLT-R DR,before and after WBRT Secondary ENDPOINT: the change of Alzheimer's Disease Assessment Scale-Cognitive，ADAS-Cog before and after WBRT;severe cognitive impairment percentage and onset time; Design:204 patients will be randomly assigned to exp.group,102 cases,and 102 cases of control group.
Lumbar puncture is a diagnostic procedure performed as part of the etiological assessment of cognitive disorders. Despite good tolerance and very rare complications, lumbar puncture is still perceived as being painful or anxiety-provoking by patients. Hypnosis could improve pain and anxiety when performing lumbar puncture.
Mild cognitive impairment (MCI) and neurocognitive disorder such as Alzheimer's disease (AD) and Vascular dementia (VaD) have become common diseases in the elderly. The burden of dementia is rising in China, with major medical, social and economic impacts. To address this important public health problem, cohort study on elderly cognitive disorders should be carry out. The methods of early prevention, early diagnosis and early treatment the cognitive disorders in elderly should be found to reduce the burden of the social and economic issue due to dementia. At present, the international corresponding guidelines have taken gene and brain imaging biomarkers as important indicators of dementia pathogenesis research, accurate diagnosis and targeted intervention. The study will construct a prospective cohort to establish database that provide not only comprehensive epidemiological data on the MCI and neurocognitive disorder in ageing people, but also complete the construction of biological samples bank and clinical diagnosis and treatment information database. Using the database, the study will identify the conversion rates from MCI to dementia and risk factors for the progression from MCI to dementia or AD. The study will also apply and develop brain structural and pathological imaging technology to support precision diagnosis of senile cognitive disorders. The study have goals to identify and validate imaging and blood/CSF biomarkers for the early detection and tracking of cognitive disorders.
The burden of cognitive impairment is severe, and often hinders affected people to act independently in daily life. Individuals in different stages of cognitive decline are frequently affected by existential distress and associated health issues (such as stress symptoms, anxiety, and depression), as well as social avoidance due to the unclear prognosis. Although the need for psychological support is large, there is a lack of efficient individualized psychological treatments- and methods to maintain psychological health that sufficiently impact daily life and promote behavioral- and biological change. In keeping with that notion, the investigators have developed a novel psychological treatment manual focused on supporting individuals with early phase cognitive impairment. The treatment manual is centered on facilitating behavioral change in accordance with personal values and long-term goals even in the presence of negative experiences, as well as to promote meaningful life-style changes. Conceptually, the treatment manual has its basis in the cognitive behavioral therapy (CBT) tradition, but the investigators have strived to adapt the manual to suit a cognitively affected population. The investigators will evaluate the psychological treatment in a RCT were the investigators will include approximately 138 individuals in their early phases of cognitive decline and randomize them into either an experimental group (psychological treatment), an active control group (cognitive training), or a treatment as usual control group. Evaluations will be conducted with, psychological health measures, cognitive assessments, and with biological markers. The investigators hypothesize that in comparison with the control conditions, the response to psychological treatment will be associated with improved psychological health and improved cellular protection.
This is a multi-center study that has three cohorts: 1) cognitive normal cohort (CN), 2) Alzheimer's disease cohort (AD) and 3) vascular cognitive impairment cohort (VCI). The goal of this study is to understand the risk factors of AD and VCI and to identify high risk patients for early intervention. It will collect demographic information, family history, medical history, neuropsychological tests, imaging studies and biological samples through standard and uniform procedures.
This study will assess cognitive function in patients with a primary brain tumour treated with radiation therapy (RT) to generate radio-sensitivity and volume effect parameters for the development of cognitive dysfunction. All types of brain tumours apart from glioblastoma will be included.
Endocrine therapy (ET) is widely used to treat hormone receptor positive breast cancer and prevent recurrence by downregulating estrogen function. However, ETs readily cross the blood brain barrier and interfere with the action of estrogen in the brain. Estrogen supports cognition and menopausal status is closely linked to cognitive health in women. This has raised concern that anti-estrogen ETs may affect cognition and brain health in breast cancer survivors. However, evidence across existing studies is inconsistent and these effects remain poorly understood. The incomplete understanding of the effects of ET are likely due to limitations of earlier studies - namely, the under-appreciation of the role of menopausal status and insensitivity of standard cognitive measures. This research project will address these earlier limitations by specifically comparing ET effects by menopausal status, and using highly sensitive, task-related functional magnetic resonance imaging (fMRI) measures to assess the effects of ET on brain function.
This study aims to investigate the incidence and characteristics of cognitive Impairment(CI) in the elderly patients with acute coronary syndrome (ACS), and to determine whether CI are predictive of the prognosis of major adverse cardiovascular events (MACE) and mortality.
