About this study

This study conducted a retrospective analysis of 64 patients with mild cognitive impairment of the kidney deficiency phlegm and stasis type who underwent treatment with Naohuan Dan combined with Idebenone. The patients' cognitive function was evaluated using the Mini-Mental State Examination (MMSE) and the Montreal Cognitive Assessment (MoCA) before and after treatment. Daily living abilities were assessed using the Activities of Daily Living (ADL) scale, depression status was evaluated using the Geriatric Depression Scale (GDS), and the severity of Traditional Chinese Medicine (TCM) syndrome was assessed using the TCM diagnostic scale. Peripheral blood from the patients was also collected for analysis of neuron-specific enolase (NSE) and inflammatory factors. The aim was to evaluate the safety and feasibility of using Naohuan Dan combined with Idebenone for the treatment of mild cognitive impairment of the kidney deficiency phlegm and stasis type.

What is being measured

The primary outcome is the main question the study is designed to answer.

  1. Change from the Mini-Mental State Examination scale (MMSE) at 12 weeks

    The MMSE scale measures various cognitive domains, including orientation (10 points), memory (3 points), attention and calculation (5 points), recall ability (3 points) and language skills (9 points).

    Measured: The time of measurement for the scale occurred twice, with the first measurement taking place before subjects were enrolled, and the second occurring at the end of their 12-week continuous medication period. Each assessment will last for one day.

  2. Change from the clinical efficacy at 12weeks

    The clinical efficacy was evaluated based on the MMSE scale, and the efficacy was calculated by comparing the scores before and after the therapy. The following criteria were used to determine the efficacy: (i) Markedly effective: ≥20% improvement in MMSE score. (ii) Effective rate: ≥12% improvement in MMSE score. (iii) Ineffective: <12% improvement in MMSE score.

    Measured: The time of measurement for the scale occurred twice, with the first measurement taking place before subjects were enrolled, and the second occurring at the end of their 12-week continuous medication period. Each assessment will last for one day.

Secondary outcomes (5)
  1. Change from the Montreal Cognitive Assessment scale (MoCA) at 12 weeks

    The MoCA scale is a widely used screening tool for detecting mild cognitive impairment. The total score on the MoCA scale is 30, and a score of 26 or higher is considered to indicate normal cognitive function.

    Measured: The time of measurement for the scale occurred twice, with the first measurement taking place before subjects were enrolled, and the second occurring at the end of their 12-week continuous medication period. Each assessment will last for one day.

  2. Change from the Activities of Daily Living scale (ADL) at 12 weeks

    The ADL scale is used to assess the participants' ability to perform daily living activities. The total score on the ADL scale is 100 points.

    Measured: The time of measurement for the scale occurred twice, with the first measurement taking place before subjects were enrolled, and the second occurring at the end of their 12-week continuous medication period. Each assessment will last for one day.

  3. Change from the Geriatric Depression scale (GDS) at 12 weeks

    The GDS scale is a self-report assessment tool used to detect and measure the severity of depression in older adults. The total score on the GDS scale is 30 points.

    Measured: The time of measurement for the scale occurred twice, with the first measurement taking place before subjects were enrolled, and the second occurring at the end of their 12-week continuous medication period. Each assessment will last for one day.

  4. Change from the traditional Chinese medicine (TCM) syndrome score scale at 12 weeks

    The TCM clinical symptoms of the participants were evaluated using the TCM syndrome score scale. This tool assesses the severity of specific TCM symptoms and divides them into four grades: none, mild, moderate, and severe, with 0, 2, 4, and 6 points (for main symptoms) or 0, 1, 2, and 3 points (for secondary symptoms), respectively.

    Measured: The time of measurement for the scale occurred twice, with the first measurement taking place before subjects were enrolled, and the second occurring at the end of their 12-week continuous medication period. Each assessment will last for one day.

  5. Change from the Serological indicators at 12 weeks

    Blood samples were collected from the participants before and after the therapy via cubital venipuncture. Enzyme-linked immunosorbent assay (ELISA) was used to determine the serum levels of neuron-specific enolase (NSE), interleukin-8 (IL-8) and tumor necrosis factor-alpha (TNF-α).

    Measured: The time of measurement for the scale occurred twice, with the first measurement taking place before subjects were enrolled, and the second occurring at the end of their 12-week continuous medication period. Each assessment will last for one day.

Questions about this trial

What is this clinical trial studying?

An observational study of Mild Cognitive Impairment, run by Sun Yat-Sen Memorial Hospital of Sun Yat-Sen University at 1 site in China.

The full registered description is in the About this study section and the official record.

Who may be eligible to take part?

The sponsor lists 4 inclusion and 4 exclusion criteria. Eligibility is decided by the study team after screening, so read the full criteria and contact a listed site.

Is this clinical trial currently recruiting?

The record says: finished, as of the sponsor's last update on 5 Jul 2023. Status can change between updates, so confirm with the study contact before making plans.

Where is the study taking place?

The record lists 1 site in China. Whether a site is taking part right now should be confirmed with that site. See every site.

What are the possible benefits and risks?

They depend on the study and the treatment, and no study can promise a benefit. The study team explains the known risks during informed consent, before anyone joins; the record itself does not list them.

Are results available for this study?

The study is completed, but results are not available in the source record. That does not mean the treatment did or did not work.

How can a doctor refer a patient or contact the research team?

The record lists no contact. The official record names the sponsor, who can be asked directly. AzTrials does not enrol participants or take referrals.

What does the primary outcome measure?

Change from the Mini-Mental State Examination scale (MMSE) at 12 weeks (time frame: The time of measurement for the scale occurred twice, with the first measurement taking place before subjects were enrolled, and the second occurring at the end of their 12-week continuous medication period. Each assessment will last for one day.). The study lists 2 primary outcomes in all. It is what the study was designed to measure, not a finding.

Where can I read the original study information?
Does a listing mean the treatment is approved or proven to work?

No. A listing means the study is registered. It does not show that the treatment is safe, works, or is approved by a regulator.

How often is this information updated?

AzTrials copies changed records from ClinicalTrials.gov every night and reloads the whole registry every week. The sponsor last updated this record on 5 Jul 2023.
