Study of the Therapeutic Effects of Naohuan Dan and Idebenone in Treating Mild Cognitive Impairment With Kidney Deficiency and Phlegm Stasis
- Conditions
- Mild Cognitive Impairment
- Interventions
- Drug: Naohuan Dan and Idebenone
- Registration Number
- NCT05931029
- Brief Summary
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.

At a dose of one per day, delivered with warm water in the morning and evening, and taken orally for 12 consecutive weeks.
- Primary Outcome Measures
Name Time Method Change from the Mini-Mental State Examination scale (MMSE) at 12 weeks 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 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).
Change from the clinical efficacy at 12weeks 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 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.
- Secondary Outcome Measures
Name Time Method Change from the Activities of Daily Living scale (ADL) at 12 weeks 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 ADL scale is used to assess the participants' ability to perform daily living activities. The total score on the ADL scale is 100 points.
Change from the Geriatric Depression scale (GDS) at 12 weeks 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 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.
Change from the Montreal Cognitive Assessment scale (MoCA) at 12 weeks 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 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.
Change from the Serological indicators at 12 weeks 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. 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).
Change from the traditional Chinese medicine (TCM) syndrome score scale at 12 weeks 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 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.
