Abstract: A newly discovered diagnostic protocol that localizes a disorder of the human body to the brainstem and also possibly the limbic system of the human body with a clinically proven protocol for treatment of the disorder. Treatment for dysfunction of other parts of the body associated with the brainstem disorder is outlined. This diagnostic protocol and treatment protocol has been designated with the acronym BALD. This discovery covers neurological disorders caused by toxic substances, by infection, and by a combination of toxic substance and infection causative factors. The diagnostic protocol outlines a step by step procedure for determination of the BALD syndrome and the treatment protocol outlines a step by step procedure for the physician to treat the syndrome as well as for clinically successful treatments of other parts of the body associated with the BALD syndrome.
