Experiencing both of my parents dying with dementia has given me a special interest in how treatments and ways of managing it are developing. While my father only had the disease for a relatively short time, my mother endured it for 7 years, and I became an observer of the slow progression of this truly dreadful disease. My father died 16 years ago and my mother 6 years ago.
The sad fact is that there still aren't any good treatments.
More recently there is a growing body of evidence which is pointing to the fact that acupuncture may prove to have a role in the treatment, and possibly even prevention of dementia. It is still (very) early days and I am not saying that the case is at all proven yet, but it seems to me that there is “a lot of smoke for there not to be any fire”. Only time, funding and research will tell how significant these new findings are. Unfortunately funding for acupuncture is slow because there is no 'pot of gold' at the end e.g. for a drug company.
One new Taiwanese study published in 2017 looked at 11000 stroke patients - half of whom had acupuncture rehab. treatment after their stroke. It showed that about 23% less of the patients who got acupuncture went on to develop dementia in the following 5 years compared to those who didn't have the acupuncture. This is a big study by any standards and hopefully will generate interest & follow up studies. It is not a perfect study and for example did not exclude all other possibilities as to why some went on to develop the disease and others didn't (eg smokers/obesity etc.), but nonetheless it was otherwise a well conducted study and is very interesting. It was published in the BMJ (online edition)¹.
Other studies in the links below are showing that acupuncture can help with Cognitive function tests in dementia patients, ADL (activities of daily Living) scores can be improved and further research is pointing to possible mechanisms how acupuncture might help e.g. Blood flow to the brain, glutamatergic neurotransmission & various other measurable blood chemistry parameters.
While it will probably take another decade or longer to 'prove' (or disprove) the case for acupuncture in the treatment of dementia I believe that when the currently available facts on how acupuncture may help are added to it's efficacy in treating depression and anxiety (which often accompany dementia) there can be a good case to use acupuncture now, in some limited* circumstances. It is widely used in China today.

They appeared to be 23.4% less likely to develop dementia if they had acupuncture as stroke rehab. Looks like good quality study with huge numbers. Follow up was over 5 years.

“ In the present study, EA at Du20 (an acupuncture point on the top of the head) was observed to reverse the cognitive impairments in APP/PS1 transgenic mice via modulation of BDNF expression and processing” the study concluded “... acupuncture may exert neuroprotective effects by modulating the expression and processing of BDNF. These results suggest thst Electroacupuncture at DU20 may serve as a promising strategy for Alzheimers Disease”
