FIVE-PART �PRIMETIME� SERIES, �MEDICAL MYSTERIES,� EXAMINES RARE AND EXTRAORDINARY MEDICAL CASES, PREMIERING WEDNESDAY, JULY 26 ON ABC

Medical science has progressed exponentially in recent times, but scientists are still left with unanswered questions when it comes to the human body. From why a mother can�t recognize her own child�s face to why a young woman spends most of her life sleeping, �Medical Mysteries� looks at some of the rarest disorders and syndromes in medicine today. Each hour of the five-part series will feature baffling medical conditions, as well as the doctors who are working on cures. �Medical Mysteries� premieres on �Primetime,� WEDNESDAY, JULY 26 (10:00-11:00 p.m., ET) on the ABC Television Network, and will continue for four additional weeks on Wednesdays at 10:00 p.m.

Over the course of the series, doctors will solve genetic puzzles, explaining how these and other rare conditions occur and why, including:

o Sleep disorders that lead people into violence -- in an unconscious state -- that can cost them their lives.

o Three generations of a family facing a fatal disease find hope by removing an organ most people can�t imagine living without.

o A woman whose hidden DNA leaves her unable to prove her identity or provide a connection to her biological child.

o Senses far beyond the normal functions of sight, smell, hearing, taste and touch.

o How an in-utero �fight to the death� between twins can leave the surviving twin with a bizarre condition, unless risky laser surgery can save them both before they are born.

o Attributes typically ascribed to werewolves are found in a human syndrome marked by an aversion to daylight, excessive hair on the face and body and sharp purple teeth.

Also, each hour of the limited series will feature a real medical mystery component designed for viewer participation. This segment, called �You Be the Doctor,� will provide viewers with clues to help them make their own online diagnosis in a real case. At the end of each hour, viewers will learn how well they scored.

Terence Wrong and Ann Reynolds are the senior producers of �Medical Mysteries.� Rudy Bednar is the executive producer.
