Beneficial Effects of Mindfulness-based Training on Neuropsychological Outcomes in Mild Cognitive Impairment — MEDIC  

Mild Cognitive Impairment Clinical Trial

Official title: Investigating the Beneficial Effects of Mindfulness-based Training on Neuropsychological Outcomes in Mild Cognitive Impairment

Status Completed

Clinical Trial Summary

This study evaluates the effects of Mindfulness-based Interventions (MBI) on the neuropsychological profile of individuals with mild cognitive impairment (MCI). It will also investigate changes in fMRI activity, such as resting-state functional connectivity networks and changes in activity in attention networks in task-related fMRI using graph theory analysis after Mindfulness-based Interventions. Participants will be randomly assigned to receive either the Mindfulness-Based Intervention, Cognitive Rehabilitation Training or Treatment as Usual as the passive control group comparison.

Clinical Trial Description

As the population of Singapore ages rapidly, cognitive decline associated with both normal aging and disease is becoming a frequently encountered health challenge. In our proposed study, we will investigate the effects of mindfulness-based interventions (MBI), which have shown significant promise in halting and even reversing age-related cognitive impairment. MBI enhances the quality and frequency of mindfulness, defined as a mental state achieved by focusing one's attention and awareness on the present moment, while calmly acknowledging and accepting one's feelings, thoughts, and bodily sensations. In this study, we will administer a standardized MBI program or Cognitive Rehabilitation Therapy to a group of 60 patients diagnosed with mild cognitive impairment (MCI), a condition marked by deficits in language, memory and attention that often leads to dementia; an additional 30 patients will be assigned to the control group. There will be 3 runs with 30 persons per run; each group will have 10 randomly assigned participants. By comparing the 3 groups across the 3 runs, we seek to test the following hypotheses: 1) MBI will result in significantly greater improvements in neuropsychological testing outcomes across multiple cognitive domains, including attention, memory, language and processing speed, 2) MBI will strengthen cortical connectivity as measured by functional magnetic resonance imaging (fMRI), and 3) MBI will lead to changes in fMRI activation on a test of facets of attention. Neuropsychological testing will take place in SGH, while fMRI and EEG scanning will take place in the Center for Cognitive Neuroscience at Duke-NUS. Both the MBI and CRT will be facilitated by trained personnel. Our proposed experiment comprises one of the most comprehensive interrogations of the effects of MBT on patients to date, and if successful, could rapidly translate into a program with both clinical and economic impact. ;
