Bolzan had suffered a blow to the back of his head and was treated for a severe concussion. After three days in the hospital, he was released and sent home. The doctors told his family that he would be a little fuzzy but would recover within the week.
"At that early concussion stage, those gaps in memory are normal, no one thought anything of it," said Joan Bolzan.
Scott remembered the disorientation that followed his accident.
"On the drive home, it was, again, anxiety," he said. "I'm like, 'Where am I going, what is this going to bring me now? Where do we live, what do we do?' And then we walk in this house and I'm like, 'OK, where do I go?'"
On the outside he seemed fine. But what Bolzan didn't tell anyone was that everything seemed foreign. He had no recollection -- of anything. Not his wife, not his children, not a single thing in their home.
"Nothing looked familiar, not one thing," Bolzan said. "You know, in this bathroom, I'm sure I showered in there a thousand times, or whatever, but nothing looked familiar. ... I started opening up drawers and I went into my closets. ... I just started looking at things, but nothing looked familiar, but it looked like it would fit me so then I started rationalizing things of, OK, maybe I did live here, maybe this is my home."
But even more disturbing to Bolzan was that he had no clue who he was.
"It was just a lost feeling of not knowing where I am in this world and who I am," said Bolzan. "So that was a very difficult day."
The days turned into weeks, and the weeks turned into months. It became impossible for Bolzan to hide the vastness of his amnesia from those around him.
"I didn't have any concept of like my parents, my wife, children, family friends, relatives," Bolzan said. "My wife would tell me about my parents, but every time we talk now, it's like an interviewing process. I'm trying to gather information, what was I like as a kid, what was our relationship like. ... I did not have the concept of husband and wife. What a husband did for a wife and what a wife did for a husband."
"He had lost everything historical as well," Joan Bolzan said. "Turned on the TV, he didn't know one historical person, one actor, he didn't know anything."
Scott recalled the anxiety he felt.
"I had a fear of running into someone I knew 20 years, and they say, 'Hi Scott,' and I have no idea, and they're like, 'What's wrong with you?'" Bolzan said. "I cried for -- months, I mean, I did not want to leave the house for months."
Joan Bolzan said she still sheds tears.
"He was the only person I've ever known my whole adult life, and experienced marriage ... and parenting, and all those things that you share together as a couple," she said. "And the things that you know between the two of you, he doesn't have any more."
Four months after the accident, Scott still had no memories.
"One neurologist said, you probably need a psychiatrist," he said.
He started to question his own sanity.
"We'd go to one neurologist," said Joan, "and they're like, 'I've never heard of anybody losing their entire life.' So they didn't know."
They switched doctors several times, and finally Bolzan underwent a brain scan that seemed to provide a medical explanation for his rare condition.
"It was determined that I have no blood flow going to the right temporal lobe of my brain," said Bolzan. "Which is where all my long-term memory is stored."
