New Delhi: Acupuncture is a Chinese therapy of relieving stress or muscle pain by inserting needles at strategic point on your body. This complimentary medical practice promotes natural-healing process of the body and also manipulates flow of energy. A recent study highlights that the use of acupuncture alone can treat pre-dementia state, known as mild cognitive impairment (MCI).

And it may be particularly effective when combined with drug treatment, the Wuhan University findings indicated, although the researchers cautioned that further better quality research is needed.


The researchers trawled Western and Chinese research databases for relevant trials comparing acupuncture and medical treatment that had been published up to July 2015.


Out of 10 trials, five that involved a total of 568 people and had been published in 2012 and 2013 were deemed suitable for inclusion in the study. Three directly compared acupuncture with nimodipine, while two evaluated acupuncture combined with nimodipine.


The number of participants in each study varied from 26 to 94, while acupuncture treatment was provided three to five times a week for 8 weeks in four trials, and for 3 months in one.


Analysis of the pooled data showed that those in receipt of acupuncture fared better than those on nimodipine alone. And they achieved better scores on two of the principal tests used to assess MCI and dementia: the mini mental state exam and picture recognition.


Furthermore, a combination of acupuncture and nimodipine significantly improved mini mental state exam scores whencompared to nimodipine alone.


Three of the trials reported side effects, which for acupuncture included fainting during treatment and slow bleeding (errhysis) at the needle sites, and for nimodipine included gut symptoms and mild headache.


The researchers point to several caveats, including the high or unclear risk of bias in the trials, the randomisation process, and the trial design which didn't take account of potential placebo effects. Most of the trials were also carried out in China where patients may prefer acupuncture to medical treatment.


Despite the promising findings, further large rigorous clinical trials in Western settings are needed before any firm conclusions can be drawn about the effectiveness and safety of acupuncture for treating MCI, concluded the researchers.


The study is published in Acupuncture in Medicine.
