Exploratory clinical trial of low frequency therapy for mild cognitive impairment.
Basic Information
Recruitment status | Pending |
---|---|
Health condition(s) or Problem(s) studied | mild cognitive impairment |
Date of first enrollment | 19/06/2024 |
Target sample size | 30 |
Countries of recruitment | |
Study type | Interventional |
Intervention(s) | Low-frequency therapy equipment is administered. Bathing should be avoided during stimulation and the patient should be allowed to walk and move around, but only to the extent that the electrodes are not displaced. During stimulation, the patient can use the toilet, eat and sleep, and there are no restrictions on behaviour or position. Stimulation is applied to the auricle with a sticker for 1 hour once a day at 1.5 mA, 25 Hz for 250 us. Stimulation is based on 1.5 mA, 25 Hz for 250 us, but habituation may occur, in which case the researcher should check and adjust the stimulation frequency between 1 and 20 mA, 2 and 100 Hz, aiming for crackling but not pain. Adjustments are made. |
Outcome(s)
Primary Outcome | Change in Clinical Dementia Rating Scale (CDR-SB score) from study entry to 52 weeks. |
---|---|
Secondary Outcome | (i) Safety in the implementation of infrasound therapy and whether or not adverse events have occurred. (ii) Changes in ADAS-cog14 and ADCOMS before and after low-frequency treatment (iii) The localisation of immune cells before and after infrasound treatment, the positive expression of a group of molecules whose expression is induced by inflammation, the intensity of expression, and the presence or absence of disease-related gene variants and their association with the pathological condition. Correlations between the state of inflammation and the expression status of other analysed molecules. |
