Filter by:The purpose of this study is to determine whether cognitive rehabilitation is effective in patients with gliomas (brain tumour), by comparing direct and follow-up neuropsychological functioning and quality of life of the experimental group to the control group.
Neurodegenerative diseases, such as Alzheimer's disease, Parkinson's disease, and multiple sclerosis are recognized as a major health concern at the present time. There is information in magnetic resonance imaging (MRI) studies regarding the role of brain iron in normal brain aging that may be enhanced with the use of better scanning equipment and procedures, and by correlating this information with clinical data. This research study aims to develop and evaluate a number of techniques that can potentially improve the effectiveness of three tesla (3T) magnetic resonance imaging of neurodegenerative brain disorders.
The study will investigate the viability of two cognitive rehabilitation strategies to improve functional outcomes for people with schizophrenia. Many people with schizophrenia experience impairments in cognitive function which limit their abilities. These impairments have been shown to precede the onset of illness and represent a vulnerability factor which is exacerbated by emerging psychotic symptoms. These impairments affect a range of functional domains including symptom severity, work function, symptom management, treatment, and overall quality of life. Recognizing the link between cognitive impairment and function, a few clinicals and researchers have attempted to remediate cognitive impairments by providing cognitive retraining programs similar to those used in traumatic brain injured patients or adaptive skills training. Cognitive retraining involves repetitive exercises to increase elemental cognitive functions including memory, attention, psychomotor speed, planning, and cognitive flexibility. Adaptive skill training involves didactic group exercises in social skills, activities of daily living, and symptom management. Each approach has demonstrated some rehabilitation benefits. This study will investigate the effectiveness of a combination of these two approaches on outcomes in schizophrenia.
Our central hypothesis is that the early metabolic lesions of MCI can be reliably detected in individual subjects by objective analysis of [18]F-fluorodeoxyglucose (FDG) positron-emission tomography (PET) brain images, earlier and more accurately than by subjective clinician rating.
The purpose of this study is to determine the effects of the insulin-sensitizing medication rosiglitazone on attention and memory skills in older adults with mild cognitive impairment (MCI). The study also will examine the effects of this medication on brain structures that support memory and other thinking abilities, and on biological markers associated with inflammation, insulin resistance, and cardiovascular disease.
The purpose of this follow-up study is to assess the long-term safety and tolerability of galantamine in individuals with mild cognitive impairment who participated in a previous study with galantamine
This study is based on the hypothesis that by increasing N-methyl-D-aspartic acid (NMDA) receptor function in the brain and thereby increasing the capacity of the brain to both form new connections and strengthen existing connections, schizophrenic patients may derive both greater and sustained benefit from cognitive retraining.
The purpose of this study is to evaluate the efficacy and safety of galantamine treatment in patients with mild cognitive impairment.

ADHD is often associated with sleep difficulties. Attention-deficit/hyperactivity disorder (ADHD) is the most common problem presented to children mental health services. The disorder affects approximately 5 % of school-age children. The core symptoms of this disorder include varying degrees of inattention, impulsiveness and restlessness. In addition to the core symptoms, ADHD is associated with other problems (e.g. academic underachievement, poor social relations and sleep disturbances). Despite clinical observations of sleep problems in children with ADHD, there is little empirical research on this topic. The prevalence, type of sleep problems, and significance of these sleep disturbances in children with ADHD remain undocumented. The objective is to determine the relationship of sleep problems to attention deficit/hyperactive disorder, comorbid disorders, and the effect of stimulant treatment.
