Acupuncture is more effective in treating vascular dementia. Vascular dementia is a brain dysfunction caused by various cerebrovascular diseases, producing severe cognitive impairment, including memory, comprehension, behavioral and verbal signs and symptoms, usually lasting for months or even years, often secondary to cerebrovascular accidents, after stroke, also known as post-stroke dementia, and is one of the top three causes of disability in the elderly. Acupuncture therapy is one of the effective methods for treating this disease, improving blood circulation in the brain, promoting brain damage repair, scavenging free radicals and protecting neurons, not only relieving clinical symptoms and delaying the development of the disease, but also preventing recurrence of cerebrovascular disease.
