Acupuncture can significantly improve learning and memory capacity that has been impaired by hyperglycemia and cerebral ischemia, according to a new study.
A study published in the journal, Neuroscience Letters, reported on whether electroacupuncture (acupuncture needles stimulated with a mild electrical current) could improve learning and memory in rats whose memory and cognitive functions were impaired by the decreased circulatory effects of diabetes resulting in cerebral ischemia.
In the study, the effects of the acupuncture treatments were measured with a passive avoidance test, an active avoidance test, the Morris water maze and electrophysiology. With all tests, significant improvements were seen in restoring memory and learning capacity.
The researchers remarked that previous investigations have demonstrated that electroacupuncture can improve primary and secondary symptoms such as peripheral neuropathy and diabetic encephalopathy in diabetic rats. They believe that the positive results of this study warrant further investigation.
