Dr. Flanagan's research into the fluid mechanics of the brain - including the unique design of the sutures and base of the human skull - led to the discovery of an unmistakable link between upright posture of Homo sapiens and neurodegenerative diseases seen in aging adults. This ''link'' is in the cervical spine which contains key circulatory routes for blood and cerebrospinal fluid flow entering and exiting the brain.
In a style that is accessible to the lay reader, as well as the scientist, Flanagan explains why his discovery offers important new information and hope for the many millions of patients, family members, physicians, and scientists who are devoted to understanding the causes of - and finding cures for - neurodegenerative diseases of the brain and spinal cord.
