The Challenge: Can you solve the medical mystery of a man who suddenly becomes too dizzy to walk?
The first reader to offer the correct diagnosis gets a signed copy of my book, "Every Patient Tells a Story," and the satisfaction of solving a case that stumped a roomful of specialists.
The Patient's Story:
The middle-aged man clicked his way through the multiple reruns of late-late-night television. He should have been in bed hours ago, but lately he hadn't been able to get to sleep. Suddenly his legs took on a life of their own. Stretched out halfway to the center of the room, they began to shake and twitch and jump around. The man watched helplessly as his legs disobeyed his mental orders to stop moving. He had no control over them. He felt nauseous, sweaty and out of breath, as if he had been running some kind of race. He called out to his wife. She hurried out of bed, took one look at him and called 911.
The Patient's History:
By the time the man arrived at Huntsville Hospital, in Alabama, the twitching in his legs had subsided and his breathing had returned to normal. Still, he had been discharged from that same hospital for similar symptoms just two weeks earlier. They hadn't figured out what was going on then, so they weren't going to send him home now.
The patient considered himself pretty healthy, but the past year or so had been tough. In 2011, at the age of 54, he had had a mild stroke. He had no medical problems that put him at risk for stroke — no high blood pressure, no high cholesterol, no diabetes. A work-up at that time showed that he had a hole in his heart that allowed a tiny clot from somewhere in his body to travel to the brain and cause the stroke. He was discharged on a couple of blood thinners to keep his blood from making more clots. He hadn't really felt completely well, though, ever since. His balance seemed a little off, and he was subject to these weird panic attacks, in which his heart would pound and he would feel short of breath whenever he got too stressed. Mostly he could manage them by just walking away and focusing on his breathing. Still, he never felt as if he was the kind of guy to panic.
And he had always been quick on his feet. The first half of his career he had been in the steel business — building huge metal trusses and supports. He and his team put together 60-plus tons of steel structures every day. For the past decade he had been machining car parts. After his stroke, work seemed to get a lot harder.
The Dizziness:
A few weeks ago, he stood up and wham — suddenly the whole world went off-kilter. He felt as if he was constantly about to fall over in a world that no longer lay down flat. His first thought was that he was having another stroke. He went straight to his doctor's office. The doctor wasn't sure what was going on and sent him to that same emergency room at Huntsville Hospital. After three days of testing and being evaluated by lots of specialists, his doctors still were not sure what was going on. He hadn't had a heart attack; he hadn't had a stroke. There was no sign of infection. All the tests they could think of were normal.
The only abnormal finding was that when he stood up, his blood pressure dropped. Why this happened wasn't clear, but the doctors in the hospital gave him compression stockings and a pill — both could help keep his blood pressure in the normal range. Then they sent him home. He was also started on an antidepressant to help with the panic attacks he continued to have from time to time.

He had been home for nearly two weeks and still he felt no better. He tried to go back to work after a week or so at home, but after driving for less than five miles, he felt he had to turn around. He wasn't sure what was wrong; he just knew he didn't feel right. Then his legs started jumping around, and he ended up back in the hospital.
The Doctor's Exam:
It was nearly dawn by the time Dr. Jeremy Thompson, the first-year resident on duty that night, saw the patient. Awake but tired, the patient told his story one more time. He had been at home, watching TV, when his legs started jumping on their own and he started feeling short of breath. His wife sat at the bedside. She looked just as worried and exhausted as he did. She told the resident that when he spoke that night at home, his speech was slurred. And when the ambulance came, he could barely walk. He has never missed this much work, she told the young doctor. It's not like him. Can't you figure out what's wrong?
The resident had already reviewed the records from the patient's previous hospital admissions. He asked a few more questions: the patient had never smoked and rarely drank; his father died at age 80; his mother was still alive and well. The patient exam was normal, as were the studies done in the E.R.
The first E.R. doctor thought that his symptoms were a result of anxiety, culminating in a full-blown panic attack. The resident thought that was probably right. In any case he would discuss the case with the attending in a couple of hours during rounds on the new patients. Till then, he told the worried couple, they should just try to get a little sleep.
An Important Clue:
Dr. Robert Centor was definitely a morning person. His cheerful enthusiasm about teaching and taking care of patients made him a favorite among residents. At 7:30 that morning, he stood outside the patient's door as Dr. Thompson relayed the somewhat frustrating case of the middle-aged man with worsening dizziness and panic attacks. Then they went into the room to meet the patient. He was a big guy, tall and muscular with the first signs of middle-aged thickening around his middle. His complexion had the look of someone who spent a lot of time outdoors. Dr. Centor introduced himself and pulled up a chair as the rest of the team watched. He asked the patient what brought him to the hospital.
"Every time I get up, I get dizzy," the man replied. Sure, he had had some balance problems ever since his stroke, he explained, but this felt different – somehow worse. He could hardly walk, he told the doctor. He just felt too unstable.
"Can you get up and show us how you walk?" Dr. Centor asked.
"Don't let me fall," the patient responded. He carefully swung his legs over the side of the bed. The resident and intern stood on either side as he slowly rose. He stood with his feet far apart. When asked to close his eyes as he stood there, he wobbled and nearly fell over. When he took a few steps, his heel and toes hit the ground at the same time, making a strange slapping sound.
Seeing that, Dr. Centor knew where the problem lay and ordered a few tests to confirm his diagnosis.
You can see the review report and notes for the patient's second hospital visit below.
