Memory Training Versus Yogic Meditation Training in Older Adults With Mild Cognitive Impairment
調査の概要
詳細な説明
The purpose of this pilot study intervention is to investigate brain mechanisms of response to memory enhancement training (MET) compared to Kundalini yoga and "Kirtan Kriya" meditation using functional magnetic resonance imaging (fMRI) that will be acquired from each subject at baseline and at 12 weeks (post-randomization).
Overall, the investigators anticipate recruiting 66 adults with memory complaints and diagnosed with MCI for adults 55 years old and older. Subjects will either receive: (1) MET class for 60 minutes per week; or (2) Kundalini yoga and "Kirtan Kriya" meditation class for 60 minutes per week. All assessments will be completed immediately after the interventions for a total of 10 visits in 12 weeks and a follow-up visit at 6 months (24 weeks)to monitor the overall benefit of the intervention.

Cognitive Measures - Hopkins Verbal Learning Test (HVLT) Total Recall Score
時間枠:At baseline and at 6 months
|
Primary outcome measures were administered by a cognitive battery of neuropsychological and included memory and executive functioning.
Verbal memory was measured with the Hopkins Verbal Learning Test (HVLT) total recall scores.
The HVLT form contains 12 nouns, four words each from one of three semantic categories (e.g., precious gems, articles of clothing, vegetables, etc.), to be learned over the course of three learning trials.
When scoring the HVLT, the three learning trials are combined to calculate a total recall score.
Total scores range from 0-36 with higher scores indicating better outcome.

Clinical Global Impression Scale
時間枠:Baseline, weeks 2, 4, 6, 8, 10, 12, 24
|
The CGI measures severity of illness and global improvement.
The CGI is rated on a 7-point scale, with the severity of illness scale using a range of responses from 1 (normal) through to 7 (amongst the most severely ill patients).
CGI global improvement scores range from 1 (very much improved) through to 7 (very much worse).

Geriatric Depression Scale (GDS)
時間枠:Baseline and Week 24
|
Secondary outcomes measures included mood assessments with the GDS, a self-assessment scale often used in geriatric depression trials.
The GDS is a 30-item screening tool used to identify depression in older adults.
In scoring the Geriatric Depression Scale, each item is scored 0 or 1.
The total score on the scale ranges from 0 to 30 with higher scores indicating worse outcome.

Change in Functional Magnetic Resonance Imaging (fMRI) Connectivity
時間枠:Baseline and week 12
|
FMRI scans will be obtained at baseline and after 12 weeks follow up.
Default mode network findings were analyzed and significant effects were identified for yoga and memory enhancement training groups.
