New clue to unexplained excited delirium deaths

The headlines are often filled with this scenario: a person displaying violent, bizarre and agitated behavior is subdued by law enforcement personnel and later dies in custody. It appears to be a case of police brutality -- but is it?

According to William P. Bozeman, M.D., an emergency medicine physician at Wake Forest Baptist Medical Center, some of these deaths may be caused by an abnormal cardiac condition called Long QT Syndrome, compounded by a situation of Excited Delirium (ExD) Syndrome.

"Why do people become confused, agitated and violent, and then suddenly drop dead? That's the big question," Bozeman said. "This has been seen for well over a century, but we don't have a clear answer. It may be an important link to investigate with future research."

Bozeman is lead author of a single case study published online last month ahead of print in the Journal of Emergency Medicine that details an individual who experienced ExD. The 30-year-old man displayed bizarre, agitated behavior and was brought to the Wake Forest Baptist emergency department by police.
