Filter by:Since 2010, the field of immunotherapy has grown substantially, leading to a growing population of long-term cancer survivors treated with immunotherapy. Since cancer survivorship in immunotherapy is an emerging field, to date not much is known about psychosocial and neurocognitive survivorship-related issues in advanced cancer survivors treated with immunotherapy. Preliminary findings indicated significant psychosocial and cognitive problems in survivors of advanced melanoma persist after treatment with immunotherapy. The objective for this project is twofold. First, the investigators want to longitudinally identify survival-related problems in survivors of advanced cancer treated with immunotherapy. The second goal is to identify the efficacy of an Integrative Neuro-Cognitive Remediation Therapy (INCRT) program. The investigators will focus on the following outcomes: (1) Psychosocial consequences, such as emotional complaints, fatigue, fear of recurrence, (2) neurocognitive functioning, and (3) health-related quality of life. The INCRT combines personalized computerized cognitive training and neurocognitive strategy training, with group sessions of exercise, mindfulness, Acceptance and Commitment Therapy, and cognitive behavioral therapy. We will have three cohorts: - Cohort 1: advanced cancer survivors treated with immunotherapy - Cohort 2: cancer survivors treated with cancer therapy of any kind (excluded immunotherapy), and who have subjective complaints and/or objective cognitive impairment - Cohort 3: cancer survivors of a central nervous system (CNS) tumor, who do not have active disease in the CNS, and who have subjective complaints and/or objective cognitive impairment In the first part of the study, survival-related problems will be evaluated in cohort 1, in a longitudinal manner by means of a semi-structured interview at baseline, various questionnaires and a computerized neuropsychological test battery. In the second part of the study, patients of cohort 1, 2 and 3 with subjective or objective cognitive dysfunction can follow the INCRT program. The efficacy of the INCRT is evaluated through a pre-INCRT and post-INCRT evaluation. This evaluation consist of several questionnaires and neuropsychological tests. Long-term efficacy will be evaluated by a follow-up evaluation six months after completion of the INCRT program.
Currently 37.9 million people are living with human immunodeficiency virus (HIV) around the world (UNAIDS, 2018). Even with antiretroviral treatment (ART), the virus enters the central nervous system and can affect the following structures: amygdala, hippocampus, thalamus, parietal, frontal, temporal regions, orbitofrontal, cingulate, motor and sensory cortex; generating cognitive, behavioral and motor alterations, up to HIV-associated neurocognitive disorder (HAND) and occasionally HIV-associated dementia (HAD). Few clinical studies have been conducted using computerized cognitive rehabilitation programs to counteract neuropsychological alterations. The aim of this project is to explore the feasibility of a cognitive stimulation program (CSP) developed to strengthen cognitive domains identified as impaired through a neuropsychological assessment in asymptomatic HIV+ patients adherent to ART, with the purpose of improving their quality of life and mood disorder.
The proposed pilot further emphasizes the need for collecting language and demographic specific norms for Spanish-speaking Latino individuals in the U.S. by developing new normative test data for this demographic population. The study looks to contribute to minimize healthcare disparities and inaccurate test interpretations, which can have direct implications on diagnosis and treatment. This study will allow us to develop new neuropsychological test norms for predominantly Spanish-speaking adults by establishing expected cognitive performance on a battery of frequently used neuropsychological tests. As such, the current study will help fill a large gap in the literature pertaining to neuropsychological assessment of Spanish-Speakers living in the U.S., as well as produce data of clinical utility for providers working with this population. Finally, this pilot could serve as a model to eventually extend it to other non-English speaking populations in the US.
Traumatic brain injury (TBI) caused by accidents is a very important public health problem in Taiwan. There are many people with brain damage and cognitive dysfunction caused by traumatic brain injury every year. Currently, there is no effective treatment for cognitive dysfunction caused by traumatic brain injury. Evidence from clinical studies in recent years suggests that hyperbaric oxygen therapy may be a treatment for repairing nerves after brain injury. Many studies have shown that oxidative stress and inflammatory responses play an important role in the pathogenesis of the central nervous system. In recent years, our research team has shown that oxidative stress and inflammatory response are significantly associated with the prognosis of patients with traumatic brain injury, cerebral hemorrhage, and stroke patients. More and more evidences also show that oxidative stress and inflammatory response play an important role in the neuropathological changes of mental cognitive sequelae after traumatic brain injury. This injury may be gradual from the time of head trauma. This process begins with the generation of oxidative stress and free radicals. When the cell repair and free radical scavenging system can not effectively overcome the excessive production of free radicals, an oxidative damage reaction will occur, causing a series of inflammatory cells and cytokines to be activated. Studies have also shown that when inhibiting those free radicals that produce oxidative stress, the neurological function and cognitive function of the head after trauma can be significantly improved. It is becoming widely acknowledged that the combined action of hyperoxia and hyperbaric pressure leads to significant improvement in tissue oxygenation while targeting both oxygenand pressure-sensitive genes, resulting in improved mitochondrial metabolism with anti-apoptotic and anti-inflammatory effects. The investigators published an article this year showing that hyperbaric oxygen therapy can improve the prognosis of patients with acute stroke and increase endothelial progenitor cells in the systemic circulation. The investigators plan to conduct this research project through hyperbaric oxygen therapy and neuropsychological therapy, and using scientific tests and neurocognitive function assessments. The investigators hope to answer the following questions: (1) Whether the treatment of hyperbaric oxygen can improve oxidative stress and inflammatory response after brain injury, and observe changes in biomarker concentration; (2) Whether hyperbaric oxygen therapy and neuropsychological therapy can improve cognitive function after brain injury; and (3) which biomarkers are factors that influence cognitive function prognosis.
Fatigue is a prevalent, prolonged and partly disabling symptom following cerebral stroke. The health services has little knowledge of fatigue, both in terms of what characterizes those affected, and with regard to how fatigue can be treated. Persons going through a stroke may experience impairments in cognitive functions such as attention and memory. This will often cause previously effortless activities of daily living to become strenuous and exhausting. Experiencing a stroke will also in many cases lead to a major change in life due to other related loss of function, grief and health-related concerns. Emotional reactions like depression and anxiety are widespread. Specific knowledge of how cognitive impairment, emotional reactions and coping strategies contribute to development and maintenance of fatigue is lacking. The present research project will contribute with new and important knowledge in this area. A total of 250 adults have been followed up after stroke with multiple examinations. Average age at the time of stroke was 70 years. The investigators now plan to follow them up three to four years after stroke. This provides a unique opportunity to investigate how depression and anxiety, over time, may be related to the experience of fatigue, cognitive impairment and negative coping strategies such as worrying and rumination. The investigators will use questionnaires and cognitive tests when examining these associations. Such new knowledge about cognitive and emotional factors related to the development of fatigue long-term after stroke may help determine who is at risk of developing symptoms of fatigue. Furthermore, it can shed light on possible preventional measures, and provide better suited advice to those affected by fatigue. This knowledge can also pave the way for new, research-based treatment methods.
According to the working memory model, which accounts for the organisation of working memory, the processing of non-meaningful gestures is not clear. Some authors suggest that working memory for non-meaningful gestures has the same characteristics as the phonological loop, made up of a phonological store and of a revival process (articulatory rehearsal). These characteristics are evidenced in memory span tasks, memory span which is itself determined by the duration of the memory trace and the time required to refresh the trace by subvocal rehearsal. The investigators therefore aim to set up a gestural working memory task, which is specific, simple and reproducible, in the manner of verbal and visuospatial span tasks. It will first be an exploratory and descriptive study with healthy subjects.
Multiple sclerosis (MS) progressively leads to an increasing level of disability. That's why individuals faced with this chronic disease whose progression is unpredictable have to mobilize all their available resources. As a result, management of interpersonal relationships appears to be a key issue in adjustment to situations. Although knowledge on cognitive abnormalities in MS has been growing in recent years, there is a lack of research about social behaviour regulation skills. The few studies conducted in this field are mainly interested in emotional processing (emotional facial recognition and empathy) and skills mentalizing (theory of mind) that appear disturbed in MS. While some recent studies touch on the issue of the contextual analysis of language (that is to say, the social use of language) in MS, their assessment on a wide range of pragamtic skills has never been studied. However, the pragmatic aspects of language are known to play a major role in social adjustment. This project has three main objectives : (1) to increase general knowledge of deficits in communication and in social cognition in patients with MS, (2) to propose new leads for the evaluation of these disorders and (3) to contribute to increasing knowledge of neural basis of communication and social cognition. In order to address those objectives, the assessment will be focused on many various pragmatics skills : conversation, indirect language comprehension (indirect questions, idiomatic expressions, sarcasm) and metapragmatic knowledge in a population of 40 RR-MS patients. Those patients' performances will be compared to a group of healthy matched control subjects, potential relationships between pragmatic abilities, other aspects of social cognition (theory of mind and processing of emotional stimuli), cognitive functioning, psycho-behavioural aspects and the characteristics of the disease will be explore. Social cognition tasks have been selected for their dynamic and ecologic aspects in order to match natural social interaction. Finally, communication consideration, cognitive and cerebral skills of patients with MS will contribute to increasing knowledge of the neural basis of social cognition.
Study design was a multicenter, randomized, rater-blind clinical trial. There were two-parallel arms (1:1) to evaluate functional, clinical and cognitive efficacy of a specific cognitive rehabilitation group intervention (CR) compared with a psychoeducational group intervention (PE) in subjects with Borderline Personality Disorder (BPD).
This study is designed to examine healthy children who skip breakfast and the effects of fasting on their neuropsychological functioning and the potential benefits that a Balanced Breakfast may have on their learning abilities. It is expected that this study will provide new knowledge on how prolonged periods of 8 or more hours without food affect neurocognitive processes and thus learning how specific meals following this period of fasting, which most children experience, change those processes, potentially for the better. The hypotheses for this study are: 1. Children who consume breakfast will demonstrate significantly higher levels of attention, greater concentration, and diminished impulsivity compared to children who do not consume breakfast. 2. Children who consume breakfast will demonstrate a significantly quicker reaction time and increased accuracy in correctly identifying target stimuli from an array compared to children who do not consume breakfast. 3. Children who consume breakfast will demonstrate increased freedom from distractibility and enhanced short-term memory compared to children who do not consume breakfast. 4. Children who consume breakfast will demonstrate increased cognitive processing speed compared to children who do not consume breakfast. 5. Children who consume breakfast will have improved verbal learning compared to children who do not consume breakfast. 6. Children who consume breakfast will have improved visual memory compared to children who do not consume breakfast.
In elderly patients with atrial fibrillation (AF) the presence of silent brain infarcts and neurocognitive deficit is high despite adequate treatment with oral anticoagulation. Atherosclerosis is considered to be a chronic inflammatory disease and thrombosis and inflammation are strongly correlated. Atrial fibrillation is linked with increased levels of inflammatory markers and intensive cholesterol lowering has proven to reduce inflammation. In a prospective double-blind randomized pilot-study we want to test the hypothesis, that addition of intensive cholesterol lowering treatment besides adequate oral anticoagulation will reduce cerebrovascular lesions and will be beneficial for neurocognitive status in elderly AF patients.
