I boast all the time how I can often treat a headache with just one point. Okay, sometimes it takes two or three, and sometimes, it takes a series of visits to reduce their frequency, but acupuncture is a wonderful tool for headache sufferers.
Other neurological problems are more tricky. Nerve tissue, once severely damaged, has no chance of regenerating. So, how much acupuncture can benefit really depends on the extent of the damage and how long the patient has had it.
Research shows that acupuncture can reverse post-stroke neurology as much as 80% for some people, as long as they receive treatment within the first few months of suffering from the stroke. The longer one waits, the more permanent the damage becomes.
Often, with severe cases, frequent treatments are a must... 2x/week... 3x/week... even daily.
