Подробное описание
The proposed randomized trial aims to investigate neural mechanisms of brain connectivity when comparing response to TCC to health and wellness education classes using fMRI biomarkers of emotional regulation and cognition. Control group will include health wellness education programs (HEW) that will help to control for the non-specific social support factors. Primary outcomes include measures of depressive symptom severity. Secondary outcomes include cognition, resilience, health functioning, quality of life. Maintenance of response and relapse of major depression will be determined during 6 month (and 12 month follow-up if MRI eligible). Functional magnetic resonance imaging (fMRI) correlates of emotional processing and connectivity in related functional networks. Neural correlates of working memory, and brain structure will be examined in ½ of the sample. The researchers will investigate whether variations in emotional regulation will moderate or predict emotional and functional improvement linked to TCC.
The investigators will recruit 220 older adults with depressive symptoms who have been on a stable form of treatment for at least 4 months, who will be randomly assigned to 12 weeks of: 1.Ta-Chi-Chih (TCC) class; or 2. Health/Wellness Education Program (HEW); all for 120 minutes per week. All subjects will receive comprehensive evaluations of mood, mental and physical health, and cognition at baseline, 12 weeks, and 6 months. Changes over time in measures of depressive symptoms, resilience, quality of life, and cognition will be assessed in random regression models. The investigators anticipate that greater clinical improvement in mood and cognition will in the TCC group compared to the HEW. The investigators also expect clinical improvement to correlate with the change in the activation in the right ventrolateral prefrontal cortex (VLPFC) and amygdala in an affect labeling task, and working memory-related activation of dorsolateral prefrontal cortex (DLPFC), and change in functional connectivity in brain network activity. This is the first randomized trial of response to TCC that integrates the use of fMRI biomarkers of response to guide the development of treatment and preventive approaches in geriatric depression.

Change in Hamilton Depression Rating Scale (HDRS) Scores
Временное ограничение: Measured at baseline and 3 months
|
Clinician administered scale measures severity of depressive symptoms.
This measure includes 24 items.
Response options vary item to item and include the following ranges: [0-2], [0-3], and [0-4].
A score of 0 suggests absence of symptoms and/or difficulties and higher scores represent more severe difficulties.
Possible overall score range [0-74], higher scores representing more severe difficulties.

Change in Delayed Recall Cognitive Domain Scores
Временное ограничение: Measured at baseline and 3 months
|
Neuropsychological battery of tests which included the following domains: Delayed Recall (CVLT-II [Long-Delay Free Recall], Rey-Osterrieth Complex Figure Test [30-minute Delayed Recall]) Raw scores were transformed to z-scores (with a mean of 0 and standard deviation of 1) for each test score of interest across all participants. Thus the sample mean (across both arms) is zero for each test score. These z-scores were then averaged within each neuropsychological domain to produce composite scores. Higher scores are indicative of better performance. |

Change in Attention/Executive Function Cognitive Domain Scores
Временное ограничение: Measured at baseline and 3 months
|
Neuropsychological battery of tests which included the following domains: Attention/Executive Function (Trail Making Test A and B, Stroop Interference [Golden version]) Raw scores were transformed to z-scores (with a mean of 0 and standard deviation of 1) for each test score of interest across all participants. Thus the sample mean (across both arms) is zero for each test score. These z-scores were then averaged within each neuropsychological domain to produce composite scores. Higher scores are indicative of better performance. |

Change in Language Cognitive Domain Scores
Временное ограничение: Measured at baseline and 3 months
|
Neuropsychological battery of tests which included the following domains: Language (Controlled Oral Word Association test [FAS], Animal Fluency, and Boston Naming Test) Raw scores were transformed to z-scores (with a mean of 0 and standard deviation of 1) for each test score of interest across all participants. Thus the sample mean (across both arms) is zero for each test score. These z-scores were then averaged within each neuropsychological domain to produce composite scores. Higher scores are indicative of better performance. |

Number of Participants With Adverse Events
Временное ограничение: Measured at 3 months
|
The UKU (Udvalg for Kliniske Undersogelser) Side Effect Rating Scale organizes symptoms into 4 categories (i.e., Psychic, Neurologic, Autonomic, Other) containing 8-19 symptoms each.
Each symptom receives a score for degree and causal relationship.
Degree is scored between 0-3 with higher scores being more severe.
Causal relationship is scored as improbable, possible, or probable.
