Throughout the history of allopathic medicine, the diagnosis of many diseases has been based upon the characteristics of cells and chemicals collected from body fluids, such as venous blood (left), urine (top right: specimen jar), or cerebrospinal fluid (bottom right - spinal tap).
	The term “biomarker” refers to any chemical or cell component which can be measured before death, in order to provide an accurate signal that a disease is present.
	What physicians desperately need at this time is an objective test to confirm the presence of dementia-causing conditions (such as Alzheimer’s, Parkinson’s, or Lewy body disease) prior to death, but without the need for surgical brain biopsy.
