Cognitive Rehabilitation in People With Metabolic Syndrome and Mild Cognitive Deficits
Study Details
Study Description
Brief Summary
The goal of this clinical trial is to investigate the possibility of rehabilitation of mild cognitive deficits in people with metabolic syndrome. We aim to implement a cognitive training program on patients with metabolic syndrome and cognitive deficits, and examine its effectiveness both post-intervention (3 months) and after 12 months.
Researchers will compare two groups, the experimental group that will receive the computerized cognitive training and the control group that will receive no training.

Arms and Interventions
| Arm | Intervention/Treatment |
|---|---|
| Experimental: Computerized cognitive program 25 participants with metabolic syndrome and mild cognitive deficits; receive health advice using the World Health Organization's guidelines for Risk Reduction of Cognitive Decline and Dementia, and perform the computerized cognitive training program (BrainHQ) for 45 minutes per session, twice per week, over the 3-month intervention period. |
Other: Computerized cognitive program
BrainHQ was developed by Posit Science and includes computer-based brain-training exercises organized into six categories: Attention, Brain Speed, Memory, People Skills, Intelligence, and Navigation. Participants were instructed to perform a total of 24 sessions of computerized cognitive training at home, consisting of 45 minutes of training, twice per week, over a 3-month period.

| No Intervention: Control group 25 participants with metabolic syndrome and mild cognitive deficits; receive health advice using the World Health Organization's guidelines for Risk Reduction of Cognitive Decline and Dementia. |
Outcome Measures
Primary Outcome Measures
- Change in scores of the Montreal Cognitive Assessment (MoCA) test [baseline, post-intervention (3 months), follow-up (1 year from baseline)]
MoCA is a screening test for mild cognitive dysfunction; range 0-30, higher scores represent better cognitive function
- Change in scores of Complex Figure tests [baseline, post-intervention (3 months), follow-up (1 year from baseline)]
Complex Figures assess visuo-constructional ability and visual memory; range 0-36, higher scores represent better cognitive function
- Change in scores of Hopkins Verbal Learning Test-Revised (HVLT-R) [baseline, post-intervention (3 months), follow-up (1 year from baseline)]
HVLT-R assesses verbal memory using a list of words; range 0-36 (immediate recall) and range 0-12 (delayed recall), higher scores represent better cognitive function
- Change in scores of Digit Span test [baseline, post-intervention (3 months), follow-up (1 year from baseline)]
Digit Span assesses working memory; range 0-14 (performance) and range 2-9 (span) for forward and backward condition, higher scores represent better cognitive function
- Change in scores of semantic Verbal Fluency test [baseline, post-intervention (3 months), follow-up (1 year from baseline)]
Verbal Fluency assesses executive function that also relies on language component; higher scores represent better cognitive function
- Change in scores of Flanker task [baseline, post-intervention (3 months), follow-up (1 year from baseline)]
Flanker task assesses executive function and inhibition; range 0-48, higher scores represent better cognitive function
- Change in scores of Continuous Performance Test (CPT) [baseline, post-intervention (3 months), follow-up (1 year from baseline)]
CPT assesses executive function and inhibition; range 0-100, higher scores represent better cognitive function
- Change in scores of Set Shifting [baseline, post-intervention (3 months), follow-up (1 year from baseline)]
Set Shifting assesses executive function and set-shifting; range 0-104, higher scores represent better cognitive function
- Change in scores of N-back [baseline, post-intervention (3 months), follow-up (1 year from baseline)]
N-back assesses working memory; range 0-30, higher scores represent better cognitive function
Secondary Outcome Measures
- Change in scores of Everyday Cognition-II (Ecog-II) [baseline, follow-up (1 year from baseline)]
Ecog-II is a measure of everyday functioning that includes 41 items to assess memory, language, visual, spatial and perceptual abilities, planning, organization, and divided attention; higher scores represent worse everyday functioning
