Filter by:The goal of this study is to test the efficacy of repetitive Transcranial Magnetic Stimulation (rTMS) as a treatment for Mild Cognitive Impairment (MCI). Participants will be randomly assigned to one of three treatment groups: Group 1: Active Dorsolateral Prefrontal Cortex (DLPFC) rTMS; Group 2: Active Lateral Parietal Cortex (LPC) rTMS; and Group 3: Inactive rTMS (Placebo) control (evenly split between each coil location). Participation in the study takes approximately 7 ½ months-including a 2-to 4-week treatment phase (20 rTMS sessions) and a 6-month follow-up phase.
This study will examine self-reported neurocognitive functioning in pediatric cancer survivors whose cancer therapy may have included cranial radiation, intrathecal chemotherapy, and high-dose intravenous antimetabolite chemotherapy. There is evidence that these therapies which are directed at the central nervous system (CNS) can lead to reduced volumes of normal-appearing white matter and neurocognitive dysfunction. Neurocognitive deficits can significantly impact pediatric cancer survivors' academic success, daily functional status, and quality of life. Previous studies demonstrate the need for screening and treating neurocognitive dysfunction in childhood cancer patients and survivors. This pilot study will conduct cognitive debriefing tests with childhood cancer survivors, 30 with and 10 without neurocognitive deficits, and their parents. The collected data will aid in developing a comprehensive patient-reported outcomes (PRO) toolkit consisting of generic and specific cognitive and behavioral domains that are content-appropriate and interface-friendly for pediatric cancer populations. PRIMARY OBJECTIVE: - To conduct cognitive debriefing tests with 30 pediatric cancer survivors who have global neurocognitive impairment (i.e., the impaired group) to understand the cognitive process of answering the extant pediatric PRO measures by different levels of general intelligence quotient (IQ). Additionally, 10 pediatric cancer survivors who have at least average general IQ (i.e., the unimpaired group) will be recruited for a comparison purpose. SECONDARY OBJECTIVE: - To conduct semi-structured interviews with 30 parents/legal guardians of individuals who have global cognitive impairment as described in the primary objective in order to explore the general concept of their child's neurocognitive functioning, to rank the relative importance of different neurocognitive functioning domains, to inform a strategy for communicating with children and adolescents with impaired neurocognitive functioning for PRO research, and to suggest a user-friendly interface to collect PRO data from cognitively impaired children and adolescents. Additionally, 10 parents/legal guardians of individuals at least average general IQ will be recruited for comparison.
The purpose of this study is to explore whether active transcranial direct current stimulation during cognitive rehabilitation tasks can boost cognitive enhancement without severe side effects in mild cognitive impairment or mild dementia patients.
About 85% of patients with schizophrenia have cognitive impairments, executive functions being particularly affected. Executive dysfunction, and cognitive deficits in general, are important predictors of functional outcomes, including social problem solving, activities of daily living, life satisfaction, and the ability to return to work or school.The main objective of the current study is to examine the efficacy of group-based Goal Management Training (GMT) for patients with broad schizophrenia spectrum disorders or high risk individuals with executive deficits. The short term goals are to investigate whether GMT can improve participants' ability to organize and achieve goals in everyday life in addition to improving aspects of emotional health. A long-term goal would be to establish an evidence base for nonpharmacological interventions for patients with broad schizophrenia spectrum disorders or high risk for schizophrenia. Main research questions: (1) Does a RCT with GMT delivered to patients with broad schizophrenia spectrum disorders or high risk for schizophrenia result in improved executive functioning, measured by self-reported and/or objective measures of executive functions? (2) Does GMT result in improved goal attainment in everyday life, social- and real world functioning? (3) Does GMT have a positive impact on the patients' emotional health? (4) Are there specific characteristics in patients with broad schizophrenia spectrum disorders or high risk for schizophrenia that are associated with better treatment benefit from GMT?
The purpose of this study is to assess the effects on upper limb spasticity of soft splints worn during three weeks three hours a day by patients with stroke or disorders of consciousness.
The investigators have designed an innovative proof-of-concept trial designed to provide data as to whether the treatment/rehabilitation efficacy and functional outcome of patients with organic brain syndrome are improved with intranasal inhalations of bioactive factors (BF), produced by autologous M2 macrophages (auto-M2-BFs). The rationale for this approach is the ability of central nervous system to repair and the important role of macrophages in the regulation of this process. It was found that type 2 macrophages have anti-inflammatory and reparative potential, whereas M1 cells possess pro-inflammatory and neurotoxic effects. Action of M2 macrophages is largely realized through the production a wide variety of bioactive factors (cytokines, chemokines, growth factors, neuropeptides, microvesicles etc) that inhibit inflammation, protect neurons from apoptosis, stimulate neurogenesis, the growth and remyelination of axons, the formation of new synapses and activate angiogenesis. This study uses auto-M2-BFs, as therapeutic agents and intranasal administration focusing on nose to brain transport, as a mode of delivery. Expected clinical effects in treated subjects: improvement of cognitive functions (memory, language, attention); correction of focal neurological deficit (paresis, spasticity, sensory disorders); reduction vestibular/ataxic disorders (vertigo, unsteadiness when walking); reduction of headaches; reduction of asthenia (weakness, fatigue); correction of emotional disorders (anxiety, depression).
The investigators will investigate which patients' characteristics are associated with caregivers burden and its evolution for outpatients visiting a memory clinic, in particular how functional autonomy, behavioral and psychological symptoms as well as patients comorbidities can influence caregiver burden. The study will be conducted among outpatients with progressive cognitive complaint followed in a Memory Clinic and their primary caregiver. The investigators hypothesis that caregivers experience a higher burden due to disease symptoms such as impairment of functional autonomy, behavioral and cognitive impairment, whatever the aetiology of the cognitive decline.
The primary objective is to measure the prevalence of according to the Frascati classification in a HIV-infected population aged between 55 and 70 years (exposed group) and to compare it with the prevalence of HIV-Associated Neurocognitive Disorders (HAND) in unexposed subjects from the general population-based cohort CONSTANCES, matching subjects on age, gender, geographical origin and socioprofessional category.
The purpose of this study is to determine the sensitivity and specificity of the use of optical coherence tomography to detect HIV-associated neurocognitive disorder compared to MRI and usual cognitive screening tools.
Postoperative Cognitive Disorders (POCD) are common in hospitalized people > 60 year old, especially in orthopedic patients. Etiology of POCD is complex, and in some aspects still remains unclear. The role of thromboembolic events in etiology of POCD was discussed. The incidence of such events in patients who underwent big joints arthroplasty can be as high as 40 to 60%, although some cases are subclinical. Thromboembolic material can block a blood flow through a vessels in the brain. As a consequence cerebral neurons can be damaged or destroyed. After neuronal damage specific substances, such as S100B protein, glial fibrillary acidic protein (GFAP) and neuron-specific enolase (NSE) are released to the blood. The serum concentrations of these biomarkers can be measured. Moreover, the block of blood flow will decrease regional cerebral saturation in affected parts of the brain. In this project the authors would like to analyze the correlation between the regional cerebral saturation and serum concentration of both S100B protein and GFAP in orthopedic patients scheduled to primary hip arthroplasty.
