Active clinical trials for "Cognitive Dysfunction"

With population aging, the number of older persons with cognitive impairments increases. Literature support the effectiveness of a lifestyle approach to promote the health of persons with cognitive impairment, as well as a Lifestyle Redesign intervention to improve the general health and quality of life of frail older adults. The investigators propose to combine a multi-modal cognitive intervention and lifestyle redesign approach to improve the cognitive health of older persons with cognitive impairments.

The purpose of this study is to measure the amount of amyloid in the brain. Amyloid is a protein found in the brain of patients with Alzheimer's disease and can be detected using a Positron Emission Tomography (PET) scan. This study is interested in how amyloid levels in the brain relate to memory and thinking abilities.

Research goals: Examination of the relationship between the use of vortioxetine and cognitive efficacy in patients with schizophrenia. Examination of the association between the use of vortioxetine and the presence depressive symptoms, physical and social anhedonia in patients with the disease from schizophrenia. Examining the association between vortioxetine use and quality of life (functional recovery) in patients with schizophrenia Expected results (hypotheses) Patients with schizophrenia treated with additional therapy vortioxetine will show better cognitive achievement in memory (short-term and long-term), attention, logical reasoning and reasoning, speed of information processing, processing of visual and sound information, language and speech in relation to patients without additional intervention. Patients with schizophrenia treated with additional therapy vortioxetine will have a less pronounced presence of depressive symptoms, physical and social anhedonia in relation to untreated patients with additional vortioxetine therapy. Patients with schizophrenia who were treated with additional therapy vortioxetine will have a better quality of life, ie. better functional recovery

The purpose of this research study is to learn whether it is possible and useful for caregivers to report behavioral or psychological symptoms of people with mild memory problems or Alzheimer's disease through a smartphone mobile application. The investigators believe that monitoring these symptoms and having a tool, like a mobile application, can provide quicker accessibility to the patient's clinical care team, which could improve care for patients and caregivers. These types of symptoms found in patients with mild memory problems or Alzheimer's disease are any type of psychiatric symptoms or abnormal behaviors one might develop as the result of these brain illnesses. Examples of psychological and behavioral symptoms are depression, anxiety, insomnia, irritability, agitation, and hallucinations. These symptoms differ from regular psychiatric symptoms, because they are caused by mild memory problems or Alzheimer's disease (AD). These symptoms can cause a lot of distress for patients and caregivers, and can lead to greater use of healthcare services.

The proposed study aims to explore brain mechanisms mediating the cognitive benefits of aerobic exercise in patients with mild cognitive impairment- a prodromal stage of Alzheimer disease. We will perform FMRI experiments, as well as laboratory and behavioral tests that will advance our knowledge about the nature of these mechanisms. Participants will participate in individual- tailored aerobic training program. Pre and post evaluation will identify brain changes following the training using advanced techniques of brain imaging. Cognitive performance will be assessed prior and at the end of the program, as well as endocrine markers reflecting improvement in learning abilities. Moreover, demonstrating cortical plasticity in subjects with aMCI has tremendous practical significance for these subjects .

Patients with Parkinson's disease (PD) will be trained using a cognitive behavioral group-training-program to reduce stress and augment quality of life. An unspecific group with the same amount and frequency of meetings is used as a control group. For the evaluation of the training effects, scales to assess quality of life, analyses of psychopathological variations as well as neurocognitive tests will be used. Protocol amendment in 1-2017: addition of FU year 3 and year 5.

To evaluate the effects of multiple dose regimens of CHF 5074 administered once per day up to 2 years on potential biomarkers of neurodegeneration in subjects with mild cognitive impairment.

Many cancer survivors are experiencing problems with memory and other cognitive abilities following cancer treatment. Little is known concerning the contributions of potentially preventive therapies on cognitive function, but animal studies have pointed to the potential value of the medication fluoxetine in this context. We aim to determine whether six months of fluoxetine therapy can preserve brain function in patients who have undergone chemotherapy, and examine potential biological mechanisms for its protective effects in humans. If use of fluoxetine in cancer patients can be validated in this manner, it will represent the first drug demonstrated to prevent cerebral dysfunction associated with exposure to chemotherapy. Moreover, as this involves an agent that is already FDA-cleared for other indications, widely commercially available throughout the U.S. and other parts of the world, and relatively inexpensive since it is obtainable in generic formulations, it would represent a pharmacologic approach that is amenable to rapid translation to the clinical setting.

Dementia is a very frequent cognitive disorder among elderly individuals. Its prevalence is about 15-20% of the population over the age of 65. The most common forms of dementia among the elderly demented patients are Alzheimer's disease (AD) (prevalence of 70%) and Vascular dementia (VD) (prevalence of about 30-40%).There is also a high rate (about 40%) of coexisting of AD and VD among the dementia patients, defined as mixed dementia. Mild Cognitive Impairment (MCI) is a pre-dementia phase of cognitive decline. It is also considered as a prodromal phase of both VD and AD. Its basic clinical features include: cognitive concern, reflecting a change in cognition, reported by the patient or informant (i.e., historical or observed evidence of decline over time), with objective evidence of impairment in one or more cognitive domains (i.e., by formal cognitive testing), as well as preservation of independence in functional abilities and not being demented (i.e., no significant impairment social or occupational functioning). Hyperbaric oxygen therapy (HBOT) has been investigated for treatment of numerous diseases for more than 300 years. The principal effect of HBOT is increasing the solubility of oxygen in plasma to a level sufficient to support tissues with minimal oxygen supply carried on by hemoglobin. Clinical studies published this year present convincing evidence that hyperbaric oxygen therapy (HBOT) can be the coveted neurotherapeutic method for brain repair. Thus, it seems that HBOT might be an efficient and clinically feasible method capable of increasing tissue/cellular oxygenation and effectively evoking neuroplasticity in the chronically vascular-lesioned areas during the post microvascular lesion phase. This is a prospective, randomized, control crossed over, study evaluating the effect of HBOT in patients suffering from Mild Cognitive Impairment and Vascular Subcortical Ischemia.

The aim of the current study is to evaluate, in a prospective cross-over, randomized study, the effect of hyperbaric oxygen therapy (HBOT) on patients with chronic impairment after low grade glioma tumor removal surgery
