Active clinical trials for "Cognitive Dysfunction"

The aim of the study is to investigate whether Florbetaben (BAY94-9172)positron emission tomography (PET) is able to distinguish between subjects with mild cognitive impairment (MCI) progressing to Alzheimer's disease (AD) from those with MCI not progressing to AD.

The whole body vibration exercise group will have significantly more improvement in mobility, muscle strength, balance, balance confidence, and cognitive function with a lower fall rate than the control group.

Cognitive disorders in patients underwent general anesthesia are discussed for decades, but whether there were precise relationship between general anesthesia and dysgnosia is yet to be guaranteed. Although controversial data reported from experimental studies in animals, the investigators still proposed that general anesthetics could impair the normally organized system of the central nervous system, which finally displayed a dysfunction of cognition after general anesthesia in a short- or long-term period. Therefore, different types of general anesthetics such as inhalational anesthetics and intravenous anesthetics, the investigators hypothesized, had a long-term influence on patients' cognitive ability.

Evaluate 18F-AV-45 positron emission tomography (PET) imaging for distinguishing healthy control subjects, from subjects with Alzheimer's disease (AD) or Mild cognitive impairment (MCI).

Recent studies have described the role of melatonin as a sleep regulator and as an anti- oxidative neuroprotective agent in improving sleep quality and delaying cognitive decline in Alzheimer's disease (AD). In accordance with this data, our hypothesis is that melatonin will delay the cognitive decline in Mild Cognitive Impairment (MCI) patients and reduce the conversion rate from MCI to AD.

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.

The use of vitamin E, vitamin C, beta carotene, and/or multivitamins may keep cancer, cardiovascular disease, eye diseases, or cognitive decline from occurring. This randomized clinical trial studied vitamin E, vitamin C, beta carotene, and/or multivitamins to see how well they work compared with placebos in preventing cancer, cardiovascular disease, eye disease, and cognitive decline in male doctors aged 50 years and older.

The primary objective of this preliminary study is to investigate whether the transcranial direct current stimulation (tDCS) improves the cognitive function in patients with Mild Cognitive Impairment (MCI)

This study sought to investigate the changes in attention in older adults with mild cognitive impairment after Multi-domain Attention Training .

The purpose of this trial is to determine whether using a brain training program in the time leading up to as well as after heart surgery will reduce confusion and cognitive loss that can occur after surgery.
