Henry VIII may have suffered repeated traumatic brain injuries similar to those experienced by NFL players and others who receive repeated blows to the head, a new study suggests.
Traumatic brain injury explains the memory problems, explosive anger, inability to control impulses, headaches, insomnia—and maybe even impotence—that afflicted Henry during the decade before his death in 1547.
“It is intriguing to think that modern European history may have changed forever because of a blow to the head,” says Arash Salardini, a behavioral neurologist and co-director of the Yale University Memory Clinic.
The English monarch is best known for his dispute with the Catholic Church over his desire to annul his first marriage to Catherine of Aragon and marry Anne Boleyn. The affair led to the English Reformation and the creation of the Church of England. Henry would marry six times—and execute two of his wives.

For the study, published online in the Journal of Clinical Neuroscience, researchers analyzed volumes of Henry’s letters and other historical sources to document his known medical history and events that may have contributed to his ailments. Their findings confirm conjecture by some historians that jousting injuries caused later health and behavioral problems.
Henry suffered two major head injuries during his 30s. In 1524, a lance penetrated the visor of his helmet during a jousting tournament and dazed him. A year later, he was knocked out when he fell head first into a brook he was trying to vault across with a pole. However, the English monarch’s increasingly unpredictable behavior may have been triggered by an accident during a jousting match in January of 1536 when a horse fell on Henry, causing him to lose consciousness for two hours.
“Historians agree his behavior changed after 1536,” Salardini says, noting that descriptions of Henry during his youth portrayed an intelligent and even-tempered young man who made wise military and policy decisions. His behavior in the later years of his life became notoriously erratic: He was forgetful and prone to rages and impulsive decisions.
In 1546, for instance, he was assuring his sixth wife Catherine Parr that he would not send her to the Tower of London when soldiers arrived to arrest her. He launched into a tirade against the soldiers, having forgotten that he had given that order the day before.
Other occasional side effects of traumatic brain injury are growth hormone deficiency and hypogonadism, which may lead to metabolic syndrome and impotence, respectively. Despite the womanizing reputation of his youth, Henry had difficulty completing sexual intercourse as far back as his marriage to his second wife, Anne Boleyn, in 1533, some evidence suggests.
Other ailments attributed to Henry—such as syphilis, diabetes, or Cushing Syndrome, a condition marked by weight gain and obesity—seem less likely in light of the available evidence, according to the authors, who note that traumatic brain injury best explains most of his behavioral abnormalities.
