    Objective:To observe the effect of electroacupuncture (EA) for Alzheimer’s disease (AD).

    Acupuncture Therapy; Electroacupuncture; Alzheimer Disease; Cognition Disorders; Activities of Daily Living; Neuropsychology

    Alzheimer’s disease (AD) is the most common pattern of senile dementia. It is a chronic neurodegenerative disease[1]that usually starts slowly and gets worse over time. Common symptoms include decline in progressive learning and memory, cognitive impairment and personality change. Along with the aging population, the incidence of AD increases year by year. Studies have indicated that AD affects over 20% of people aged over 80 years. The early stage pathological process of AD may take decades. At present, there are no treatments that can stop or reverse its progression upon the presence of clinical symptoms[2-3]. There are no specific drugs yet for AD. As a result, it’s of great significance to come up with effective intervention protocol for AD. We treated 30 AD cases with electroacupuncture (EA) and evaluated their efficacies using mini-mental state examination (MMSE), revised Hasegawa dementia scale (HDS-R), activities of daily living (ADL) and neurological function defect scale (NFDS). The results are now summarized as follows.

    1 Clinical Data

    1.1 Diagnostic criteria

    This was based on the diagnostic criteria for AD in theDiagnostic and Statistical Manual of Mental Disorders-IV-Text Revision (DSM-IV-TR) by the American Psychiatric Association (APA)[4]. Presence of multiple cognitive defects, manifesting as memory decline (difficulty in learning new knowledge or unable to recall the previous knowledge) and at least one of the following cognitive defects: aphasia, apraxia, agnosia or disturbed executive function (planning, organizing, sequencing or abstracting); social or occupational impairment that declined from previous level; insidious onset with slow continuing deterioration; absence of other central nervous disorders that can affect memory and cognition (such as cerebrovascular diseases, Parkinson’s disease, Huntington’s disease, subdural haematoma, normal pressure hydrocephalus, and brain tumor, etc.); absence of clinical evidence to suggest that the mental state may be due to other systemic or brain disease which can induce a dementia (such as hypothyroidism, vitamin B1or B12deficiency, niacin deficiency, hypocalcemia, neurosyphilis, and HIV infection, etc.).

    1.2 Inclusion criteria

    Those who met the above diagnostic criteria; aged over 60 years; the legal guardian agreed to accept the intervention protocol and comply with the follow-up; willingly signed the informed consent.

    1.3 Exclusion criteria

    Those who didn’t meet the above diagnostic or inclusion criteria; having complications of severe liver, kidney or heart insufficiency; having complications of severe neurological deficit symptoms; having a family history; having cognitive impairment due to delirium or other mental disorders (such as major depression and schizophrenia); and individuals whose condition was too severe for safety and efficacy evaluation of EA.

    1.4 Statistical management

    The SPSS 19.0 version software was used for statistical analysis. Thet-test was used for measurement data, which was expressed in the form ofAPvalue of less than 0.05 indicates a statistical significance.

    1.5 General materials

    A total of 30 eligible (13 males and 17 females) AD cases from Leshan Hospital of Traditional Chinese Medicine, Leshan Geriatric Hospital and Leshan Shizhong District People’s Hospital were included between January 2014 and October 2014. These cases were aged between 60 and 85 years, with a mean age of (73.3±6.7) years. Their duration lasted between 2 and 9 years, with an average duration of (5.1 ±2.5) years.

    2 Treatment Methods

    2.1 Treatment devices

    Disposable filiform needles (manufactured by Suzhou Medical Device Factory Ltd., China) of 0.25 mm in diameter and 25 mm or 40 mm in length; and Xinsheng Brand G6805-II electric stimulator (Qingdao, China).

    2.2 Points

    Shenting (GV 24), Baihui (GV 20), Dazhui (GV14), Fengfu (GV 16), Mingmen (GV 4) and bilateral Yongquan (KI 1).

    2.3 Method

    The patient took a sitting position. After routine sterilization using 75% medical alcohol, Shenting (GV 24), Baihui (GV 20), Dazhui (GV 14), Fengfu (GV 16) and Mingmen (GV 4) were punctured 0.5 cun obliquely towards the pathway of the Governor Vessel; and Yongquan (KI 1) on both sides were punctured 0.5-0.8 cun perpendicularly. An even reinforcing-reducing manipulation was applied to each point upon arrival of qi. Then the G6805-II electric stimulator was connected respectively to Shenting (GV 24) and Baihui (GV 20), to Dazhui (GV 14) and Fengfu (GV 16) and to bilateral Yongquan (KI 1), using continuous wave at the frequency of 2-100 Hz and the voltage of 2-4 V. With a tolerable intensity, each treatment lasted 25 min. The treatment was conducted once a day for 10 d as a course. There was a 3-day interval between two courses. The therapeutic efficacies were observed after three courses.

    3 Therapeutic Efficacy Evaluation

    3.1 Measurement items and methods

    The intelligence and neurologic functions were graded and scored before and after treatment.

    3.1.1 MMSE

    The MMSE contains 30 items and has a maximum score of 30 points involving the patient’s orientation, recall, calculation and language.

    Dementia criteria by MMSE score: MMSE ≤17 points for illiterate; MMSE ≤20 points for elementary school intelligence; MMSE ≤22 points for middle school (including secondary school) intelligence; and MMSE ≤23 points for college education (including junior college) intelligence.

    Dementia severity by MMSE score: MMSE ≥21 points for mild; MMSE ≥10 points, but ≤20 points for moderate; and MMSE ≤9 points for severe.

    3.1.2 HDS-R

    The HDS-R was used to assess patients’ cognition changes before and after treatment. It has a maximum score of 30 points. Dementia is defined when the HDS-R is less than 21 points (above primary school education).

    3.1.3 ADL

    The ADL contains 14 items, 6 physical selfmaintenance scales (PSMS), 8 instrumental activities of daily living (IADL) and a maximum score of 64 points. A total score of <16 points indicates completely normal, whereas a score of >16 points indicates impaired ADL. For single item, 1 point indicates normal, 2-4 points indicate functional decline. A score of ≥3 points for two or more items or a total score of ≥22 points indicates marked impairment in ADL.

    3.1.4 NFDS

    The NFDS score ranged from 0 to 45 points. 0-15 points for mild neurological deficit; 16-30 points for moderate neurological deficit; and 31-45 points for severe neurological deficit.

    3.2 Results

    3.2.1 Changes in MMSE and HDS-R scores

    After treatment, both MMSE and HDS-R scores were significantly increased (P<0.01), indicating that EA can increase patients’ MMSE and HDS-R scores and alleviate their cognitive impairment (Table 1).

    Table 1. Changes in MMSE and HDS-R scores before and after EA treatment

    3.2.2 Changes in ADL and NFDS scores

    After treatment, both ADL and NFDS scores were significantly decreased (P<0.01), indicating that EA can improve patients’ ADL and alleviate their symptoms of neurological deficits (Table 2).

    4 Discussion

    Considering from AD symptoms such as decline in intelligence, learning, memory and ADL, social impairment and personality change, it falls under the category of ‘dementia’ or ‘forgetfulness’ in Chinese medicine. Physicians of different generations believe this condition is closely associated with the heart, brain and kidney[5]. Kidney yang deficiency can result in failure of clean yang qi to ascend to the brain. Obstruction of the Governor Vessel can result in failure of essential qi of Zang-fu organs to ascend to nourish the brain. As a result, kidney deficiency and obstruction of meridians are key factors contributing to AD[6]. The treatment strategy in this study was therefore to tonify kidney, unblock the Governor Vessel and refresh the mind.

    Of points selected in this study, Baihui (GV 20) is a crossing point between the Governor Vessel with the Bladder, Small Intestine, Gallbladder and Liver Meridians; Shenting (GV 24) is a crossing point between the Governor Vessel with Bladder and Stomach Meridians. These are two essential points for mental problems. Dazhui (GV 14) is a crossing point between the Governor Vessel and six yang meridians. Dazhui (GV 14) and Mingmen (GV 4) are two essential points to strengthen the body. Fengfu (GV 16) is a crossing point between the Governor Vessel with Bladder Meridian and Yang Link Vessel. It is a key point to remove wind and refresh the mind. Yongquan (KI 1) is the Jing-Well point of Kidney Meridian. Needling this point can tonify kidney yang and benefit intelligence.

    This study employed four neuropsychological scales including MMSE[7], HDS-R[8], ADL[9]and NFDS[10]for comprehensive objective efficacy evaluation from overall intelligence, orientation, memory, calculation, language, ADL and cognition.

    Research results have suggested that EA can increase the MMSE and HDS-R scores and decrease the ADL and NFDS scores in AD patients, indicating that this treatment protocol can effectively improve patients’orientation, memory, calculation, language, ADL and neurological deficits, stop or delay AD progression. It’s therefore worthy of clinical application.
