He didn't know what had hit him.
On Feb. 21, 2022, Endicott College sophomore Jack Smiley was practicing on the ice with his hockey teammates. He had felt fine all day. But toward the end of practice, he got hit with what he described as "a wall of all the symptoms at once."
First, he felt disoriented and couldn't catch his breath. Thinking he just needed some rest, he skated over to the bench. On the way, he noticed his right foot wasn't doing what he wanted it to do. Soon he had lost all sense of coordination.
"My right arm started not working the right way," he said. "All of the neurological signals that I tried to send to my muscles weren't firing correctly. That's when I knew something was definitely wrong."
When his teammates couldn't make sense of what Jack was saying, they called the trainer over. Within minutes, Jack was rushed to a local hospital. After being diagnosed with a stroke, he was transferred to the Neuroscience Intensive Care Unit (NeuroICU) at Massachusetts General Hospital.
Searching for what caused the stroke
David J. Lin, MD, a critical care neurologist and neurorehabilitation specialist, was part of Jack's care team at the NeuroICU. He said that Jack had suffered a stroke in the brainstem, an area that affects breathing, movement, and other critical functions. The cause of the stroke, however, was a mystery at first.
Jack's clinical team kept digging. During conversations with Jack's family, someone mentioned he had been hit in the back of the neck during a game several weeks earlier. That fact led Dr. Lin and his colleagues to revisit some imaging tests they had previously reviewed. This time, they detected on one of the images a tiny fracture in the bone that surrounds the left vertebral artery.
"This is one of the major arteries that runs up the back of the brain and supplies the brainstem," Dr. Lin explained. "We concluded that he had a vertebral dissection, or tear, of the artery due to that initial hit. That led to a blood clot that formed in the artery and later went to the brainstem and caused the stroke."
At this point, his doctors weren't sure Jack would ever walk again. However, Dr. Lin noted, it is very hard to predict what recovery from stroke will look like for any given patient. And Jack had two key factors on his side: his age and his attitude.
"Being young, fit, and physically mobile at baseline certainly helps with long-term recovery of function," Dr. Lin said. "Jack was able to achieve acceptance of what had happened early on. And he was super motivated to play hockey again, a goal that played a major role in his recovery."
