Filter by:The purpose of this study is to collect the prevalence of geriatric syndrome, which is recognized by an internist, and to compare the data based on the comprehensive geriatric assessment by a geriatrician. The secondary outcome is to develop a practical collected form for the internist.
The Diskus Inhaler is administered by a nurse or medical technician in the Nursing Home (NH) setting. The administration of the medication from the Diskus Inhaler includes 4 steps: open, click, inhale, close. The only step that the resident must do is the "inhale" step, which includes holding one's breath for 10 seconds after the inhalation. The investigators propose that properly trained and motivated nurses and medical technicians can successfully administer medication using the Advair Diskus to almost any mildly to moderately cognitively impaired resident who can follow the instruction- "inhale" and hold your breath for 10 seconds". The objective is to show that mild to moderate cognitive impairment should not be a barrier to the use of Diskus Inhaler. There will only be 1 consent visit and 1 evaluation visit per subject.
The trial will evaluate the effects of an exercise program on the physical and cognitive performance of patients with hematological neoplastic diseases after high dose chemotherapy with stem cell support.
This study evaluated the efficacy and safety of 10 cm² rivastigmine patch vs. placebo in cognitively impaired Multiple Sclerosis (MS) patients. Primary objective was the assessment of cognition by the Selective Reminding Test (SRT) -a subtest of the brief repeatable battery (BRB) - after titration of 4 weeks and maintenance of 12 weeks. This double-blind period was followed by a 52-week open-label treatment phase to assess long-term safety of rivastigmine patch in these patients.
Alzheimer's disease often manifests as a memory disorder before dementia develops. Dementia is considered to be present when a person can no longer handle complex activities of daily living, such as managing finances. This study will investigate the relationship between changes in the ability to manage finances and brain perfusion, which will be measured using continuous arterial spin-labeling (an experimental MRI). Subjects will also undergo neuropsychological tests focusing on several types of memory and thought process, with special emphasis on semantic memory. An important question to be addressed is whether changes in function are better predicted by the neuropsychological tests or by the brain scan.
Measurement of metabotropic glutamate receptor type 5 (mGluR5) binding capacity in the brain, may be a valuable tool in the early detection, understanding, or evaluation of Parkinson disease (PD), Huntington disease (HD), Fragile X syndrome (FXS), Autism Spectrum Disorder(ASD), Alzheimer's Disease(AD), and subjects with mild cognitive impairment (MCI). The goal of this study is to assess [18F]F-PEB positron emission tomography (PET) imaging as a tool to detect mGluR5 density in the brain of PD, HD, FXS ASD, AD, and MCI research participants and similarly aged healthy subjects.
The primary objective of this protocol is to determine if brain amyloid imaged with florbetapir F 18 (18F-AV-45) PET scans is predictive of progressive cognitive impairment during the subsequent 36 months for groups of: normal controls, mild cognitive impairment and Alzheimer's disease. Hypothesis 1: The probability a subject will experience progressive cognitive impairment within 36 months of imaging will be greater in subjects whose 18F-AV-45 PET scan was rated amyloid positive compared to subjects whose PET scan was rated amyloid negative. The secondary objective is to determine the stability, over 36 months of a clinical diagnosis, of AD in patients with an amyloid positive 18F-AV-45 PET. Hypothesis 2: The diagnosis of AD will remain unchanged in patients whose PET scan were rated as amyloid positive.
Purpose: The purpose of the study is to assess the safety and effectiveness of minocycline, an antibiotic, in the treatment of Human immunodeficiency virus (HIV)-associated cognitive impairment in Uganda. Study Design: Treatment, 24-week Randomized, Placebo-Controlled, Double-Blind Phase with Optional 24-week Open Label Phase for Subjects with a cluster of differentiation 4 (CD4) Count in the 251-350 Range - Arm 1: Minocycline 100 mg orally every 12 hours (50 subjects) - Arm 2: Matching placebo orally every 12 hours (50 subjects) Primary Objective: · To examine whether minocycline treatment will improve cognitive performance after 24 weeks compared to baseline Secondary Objectives: - To examine whether minocycline treatment for 24 weeks is safe and well-tolerated in individuals with HIV-associated cognitive impairment - To examine whether minocycline treatment for 48 weeks is safe and well-tolerated in individuals with HIV-associated cognitive impairment - To examine whether minocycline treatment for 24 weeks improves functional impairment
This is a 24-month study of the use of laronidase administered into the spinal fluid to treat cognitive decline in mucopolysaccharidosis I (MPS I). MPS I is a rare genetic condition due to deficiency of the enzyme alpha-l-iduronidase. Laronidase is the manufactured form of the enzyme alpha-l-iduronidase. MPS I is a heterogeneous disease with several clinical phenotypes ranging from the most severe, Hurler syndrome, to the attenuated forms, Hurler-Scheie and Scheie. Although patients with milder forms of MPS I may not have grossly observable problems with cognition, these patients do have learning difficulties that are apparent in school and with neuropsychological testing. The goal of this study is to evaluate whether intrathecal recombinant human alpha-l-iduronidase (rhIDU) injections can stabilize or improve cognitive decline in individuals with MPS I.
Postoperative cognitive dysfunction (POCD) can be a serious complication. The development of therapeutic strategies for the prevention and treatment of this condition requires the identification of subgroup of patients with the greatest incidence of POCD. Several retrospective analyses have raised the possibility that surgery is a risk factor for the accelerated progression of Alzheimer's disease (AD). Moreover, there is increasing evidence that inflammatory mechanisms are involved in the pathogenesis of AD. Major surgery can be associated with a profound systemic inflammatory response. Consequently, it is reasonable to suggest that there is a link between major surgery and the postoperative development of AD in patients who are already at high risk for this complication, e.g. the elderly with mild cognitive impairment. In addition, there are several laboratory investigations that suggest that anesthetic agents increase amyloid peptide levels as well as enhance oligomerization of these proteins. The significance of these findings, however, is unknown. This clinical study seeks to correlate perioperative inflammatory responses, perioperative changes in amyloid-beta protein levels (markers of AD) with neurocognitive and functional outcome in the elderly who are at risk for POCD. This knowledge does not exist, but is essential in the effort to plan perioperative care that can reduce the incidence of POCD as well as improve functional recovery.
