Arms and Interventions

Participant Group / Arm

Participant Group / Arm

A group or subgroup of participants in a clinical trial that receives a specific intervention/treatment, or no intervention, according to the trial's protocol.
Intervention / Treatment

Intervention / Treatment

A process or action that is the focus of a clinical study. Interventions include drugs, medical devices, procedures, vaccines, and other products that are either investigational or already available. Interventions can also include noninvasive approaches, such as education or modifying diet and exercise.
Experimental: Median nerve electrical stimulation group
The optimal median nerve electrical stimulation treatment was given
Other: Median nerve electrical stimulation treatment
Median nerve electrical stimulation is an electrical stimulation therapy in which the electrode is placed at the median nerve point 2cm above the carpal wrinkles on the palmar surface of the wrist joint. Generally, the right median nerve is used for electrical stimulation. Electrical stimulation improves cognitive function by stimulating neurons in the brain and improving information transmission between neurons. When electrical current stimulates the brain, it can increase the activity level of neurons and promote the signal transmission between neurons. Its mechanism of action includes the regulation of neurotransmitter acetylcholine, thereby enhancing cognitive function.
Experimental: Huperzine A injection + median nerve electrical stimulation group

Huperzine A injection can be administered before median nerve electrical stimulation to improve the therapeutic effect of electrical stimulation.

Huperzine A injection: intramuscular injection, 1ml,0.2mg once a day, the course of treatment was 7 days.
Drug: Huperzine A injection
intramuscular

Experimental: Huperzine A injection + median nerve electrical stimulation + Ginkgo leaf dropping pill group

Huperzine A injection can be administered before median nerve electrical stimulation to improve the therapeutic effect of electrical stimulation. After the end of the electrical stimulation treatment, ginkgo biloba dropping pills were given as long-term administration to maintain the therapeutic effect.

Huperzine A injection: intramuscular injection, 1ml,0.2mg once a day, the course of treatment was 7 days.

Ginkgo leaf dropping pills: Oral, each pill weighs 63mg, 5 pills/time, 3 times/day, the course of treatment is 3 months.

What is the study measuring?

Primary Outcome Measures

Primary Outcome Measures

In a clinical study's protocol, the planned outcome measure that is the most important for evaluating the effect of an intervention/treatment. Most clinical studies have one primary outcome measure, but some have more than one.
Outcome Measure
Measure Description
Time Frame
to assess the Mini-Mental State Examination (MMSE) score
Time Frame: baseline，Day10，Day90
Mini-Mental State Examination (MMSE): total score ranges from 0 to 30. Higher scores indicate better cognitive function.
baseline，Day10，Day90

Secondary Outcome Measures

Secondary Outcome Measures

In a clinical study's protocol, a planned outcome measure that is not as important as the primary outcome measure for evaluating the effect of an intervention but is still of interest. Most clinical studies have more than one secondary outcome measure.
Outcome Measure
Measure Description
Time Frame
to assess the Montreal Cognitive Assessment (MoCA) score

Montreal Cognitive Assessment (MoCA): total score ranges from 0 to 30. Higher scores indicate better cognitive function.
baseline，Day10，Day90
to assess the Alzheimer's Disease Assessment Scale-Cognitive (ADAS-cog) score
Time Frame: baseline，Day10，Day90
Alzheimer's Disease Assessment Scale-Cognitive Subscale (ADAS-cog): total score ranges from 0 to 70. Higher scores indicate worse cognitive performance.
baseline，Day10，Day90
to assess the Hamilton Depression Rating Scale (HAMD) score
Time Frame: baseline，Day10，Day90
Hamilton Depression Rating Scale (HAMD-24 item): total score ranges from 0 to 76. Higher scores indicate more severe depressive symptoms.
