研究概览
简要总结
The goal of this clinical trial is to assess the degree of improvement in cognitive functions, including memory, attention, thinking, executive and language functions in diagnosed patients MCI and AD taking dimethyl fumarate 480 mg daily compared to patients taking placebo. Participant will be 55 to 90 years old, both genders. The main question it aims to answer is: Changing the degree of cognitive improvement based on the RBANS score among patients diagnosed with MCI and AD after completing dimethyl fumarate therapy test group compared to the placebo group.

时间窗: 15 months
The Repeatable Battery for the Assessment of Neuropsychological Status (RBANS) is a neuropsychological measure used in the assessment of cognitive function in older adults, studies of mild cognitive impairment and Alzheimer's disease dementia, and studies evaluating the effectiveness of therapeutic interventions. The test generates index scores in five neurocognitive domains, as well as a Total Scale Index score. The RBANS is characterized by high sensitivity in detecting disease and assessing changes in scores during treatment in patients with MCI in the course of Alzheimer's disease. with MCI and AD after completing dimethyl fumarate therapy test group compared to the placebo group.
