TORONTO, Nov. 28 /CNW/ -
Dr. Adrian Upton, Head of the Department of Neurology at McMaster Health Sciences Centre today testified at the inquest into the death of Lana Lewis that, based on all of the evidence he has reviewed, Ms. Lewis died of a stroke caused by advanced atherosclerosis. During examination, he stated that a chiropractic neck adjustment she received not long before her stroke was at best "a remote possibility at the bottom of the list of probabilities" for causation. In his testimony, Dr. Upton described the advanced nature of her atherosclerosis as a "ticking time bomb" that "could have caused her to have a stroke at any time." Dr. Upton cited Ms. Lewis' numerous risk factors for stroke including smoking, hypertension, high blood cholesterol and a family history of vascular disease. He also noted that her autopsy showed extensive intra-cranial blockage of both her left and right vertebral arteries and stated that the advanced stage of the disease was unusual for someone of her age.
"I believe the facts are pretty straightforward here," he stated and further noted that determining the cause of Ms. Lewis' stroke should not be "... an intellectual game. It should be based strictly on the facts."
When questioned about Dr. John Norris' opinion that Ms. Lewis' stroke was caused by her neck adjustment and his claims regarding the incidence of stroke related to neck adjustment, Dr. Upton stated, "I am at a loss to explain how he came to these conclusions based on the facts."
"If a theory doesn't fit the facts, we change the theory," said Dr. Upton explaining how reliable science is conducted. "In scientific debate, you stick to the facts. That is not what is happening here," he stated referring to the variety of speculation and opinion linking Ms. Lewis' stroke to neck adjustment.
