Many so-called "hopeless" neurological disorders can be treated by acupuncture without the extreme side effects of tranquilizers and antidepressants often prescribed for these conditions. Acupuncture influences the nervous system by controlling and connecting neuro-physiological relationships between all body systems by directing bio-electrical impulses through the nerve fibers. It also influences the activity of the nerve cells in the spinal cord and brain. The structure and function of the autonomic nerve system and transmissions are controlled by acupuncture treatment.
