연구 개요
상세 설명
This is a pilot, open-label, prospective, randomized, comparative, controlled study in parallel groups designed to evaluate the efficacy and safety of sequential Mexidol® therapy used in addition to standard therapy in older adults with chronic brain ischemia and vascular cognitive impairment, no dementia (VCIND).
The study included 120 participants randomized into two groups:
- Group 1 received standard therapy combined with Mexidol® solution (500 mg once daily, IV infusion) for the first 5 days, followed by Mexidol® FORTE 250 tablets (250 mg three times daily) for 60 days.
- Group 2 received standard therapy only.
Within each treatment group, a pre-specified subgroup analysis was performed based on the presence or absence of frailty, followed by a comparative analysis of the secondary outcome measures for each subgroup.

Change in the Clinical Global Impression (CGI) Scale Scores at Visit 2 Compared to Visit 1, Including Severity of Illness, Global Clinical Change, and Efficacy Index
기간: Visit 1 (Day 1) and Visit 2 (Day 5)
|
The Clinical Global Impression (CGI) scale is a 3-item observer-rated scale used to evaluate illness severity, global improvement or change, and treatment response.
It consists of three independent subscales, each rated separately: CGI-Severity (CGI-S) rates the severity of illness on a 7-point scale ranging from 1 (normal, not at all ill) to 7 (among the most extremely ill patients); CGI-Improvement (CGI-I) rates the patient's change over time on a 7-point scale ranging from 1 (very much improved) to 7 (very much worse); CGI-Efficacy Index is a 4x4 rating scale that assesses the therapeutic effect and treatment-related adverse events.
Scores range from 00 (not assessed) or 01 (marked improvement and no side effects) to 16 (unchanged or worse and side effects outweigh the therapeutic effects).
A lower score reflects a better therapeutic index.

The Mini-Mental State Examination (MMSE) is a 30-point questionnaire of global cognitive status that assesses five key areas of cognitive function: orientation, registration, attention and calculation, recall, and language.
Total scores range from 0 to 30, with higher scores indicating better cognition.
A score of 24 or more indicates normal cognition.
Scores below 24 indicate cognitive impairment, categorized as mild (19-23 points), moderate (10-18 points), or severe (≤9 points) [30-point scale: min value 0, max value 30, higher scores mean a better outcome].

기간: Visit 1 (Day 1) and Visit 4 (Day 65±2 days)
|
The Lawton Instrumental Activities of Daily Living (IADL) Scale is an 8-item instrument used to assess independent living skills and complex occupational performance.
The scale evaluates 8 functional domains: ability to use telephone, shopping, food preparation, housekeeping, laundry, mode of transportation, responsibility for own medications, and ability to handle finances.
Each item is scored as either 0 (dependent) or 1 (independent).
The total score is calculated as the sum of all 8 domains ranging from 0 to 8. A score of 0 represents low functioning (maximum dependence) and a score of 8 represents high functioning (full independence) [Scale range: 0 to 8; higher scores indicate a better outcome].

|
The Barthel Index (BI) for Activities of Daily Living is a validated 10-item clinician- or caregiver-reported rating scale used to assess a patient's performance and level of independence in basic activities of daily living (ADL) and mobility.
The index evaluates 10 functional domains: feeding, bathing, grooming, dressing, bowels, bladder, toilet use, transfers, mobility, and stairs.
Items are scored in increments of 5.
The total score is calculated as the sum of all 10 items, ranging from 0 to 100.
A score of 0 represents complete dependence, while a score of 100 represents complete independence.

Change in the Short Physical Performance Battery (SPPB) Total Score at Visit 4 compared to Visit 1
기간: Visit 1 (Day 1) and Visit 4 (Day 65±2 days)
|
The Short Physical Performance Battery (SPPB) is a standardized assessment tool used to evaluate lower extremity function and mobility in older adults.
It consists of three objective subtests designed to mimic everyday physical demands: a 4-meter walk to assess gait speed, a repeated chair stand test (rising from a seated position 5 times) to assess lower limb strength, and three 10-second static balance tests in different foot positions (side-by-side, semi-tandem, and tandem).
Each of the three subtests is scored from 0 to 4, resulting in a total summary score ranging from 0 to 12. Lower scores indicate poorer physical function and higher disability, while higher scores indicate better lower extremity performance and functional independence.
[Scale range: 0 to 12; higher scores indicate a better outcome].

The Digit Symbol Substitution Test (DSST) is used to measure attention, processing speed and executive function.
It is a pencil and paper test of psychomotor performance in which the subject is given a key grid of numbers and matching symbols and a test section with numbers and empty boxes.
The test consists of filling as many empty boxes as possible with a symbol matching each number.
The score is the number of correct number-symbol matches achieved in 90 s.
Scores range from 0 to 100, with higher scores indicating higher cognitive function.

The Multidimensional Fatigue Inventory (MFI-20) is a 20-item self-administered questionnaire designed to measure fatigue in five 4-item subscales: General fatigue, Physical fatigue, Reduced activity, Reduced motivation and Mental fatigue.
MFI-20 has an even proportion of positively and negatively worded items that are rated on a 5-point Likert scale.
Subscale scores (range 4-20) are calculated as the sum of item ratings and a total fatigue score (range 20-100) is calculated as the sum of subscale scores.
Higher scores indicate a higher level of fatigue.

The Tinetti Gait and Balance Test is a clinical test for the assessment of balance and gait.
It has a gait score and a balance score using a 3-point ordinal scale of 0, 1 and 2. Gait is scored over 12 and balance is scored over 16 totaling 28.
The lower the score on the Tinetti test, the higher the risk of falling.
Tinetti test score equal or less than 18 shows high risk of fall, 19-23 scores show moderate risk of fall, and score equal or higher than 24 shows low risk of fall.
Min value is 0, max value is 28, higher scores mean a better outcome.

기간: Visit 1 (Day 1) and Visit 4 (Day 65±2 days)
|
The Morse Fall Scale (MFS) is a validated 6-item clinician-reported tool used to assess a participant's risk of falling.
It evaluates six variables: history of falling, secondary diagnosis, ambulatory aid, intravenous therapy, gait/transferring, and mental status.
The total score is calculated as the sum of all items, ranging from 0 to 125.
Scores are stratified into low risk (0-24), moderate risk (25-44), and high risk (≥45) of falling.
[Scale range: 0 to 125; higher scores indicate a worse outcome].

The Falls Risk Self-Assessment Scale is a 12-item self-administered questionnaire used to evaluate a participant's perceived risk of falling.
For each question, a "no" answer is scored as 0 points, while a "yes" answer is scored as either 1 or 2 points, depending on the item weight.
The total score is calculated as the sum of all 12 items.
Total scores are interpreted as follows: a score of less than 4 points indicates a low risk of falling, and a score of 4 or more points indicates a high risk of falling.

|
The Trail Making Test Part A (TMT-A) is a neuropsychological instrument used to assess visual search, scanning, speed of processing, and executive function.
Participants are required to connect a set of 25 encircled numbers in numerical order as rapidly as possible.
Performance is scored based on the total time taken to complete the task, where each second equals 1 point.
A higher score (longer completion time) indicates cognitive impairment, while a lower score indicates better cognitive performance and faster processing speed.
