When I tripped over my daughter’s bathroom stool and hit my head on the bathtub, I thought it was harmless. I didn’t lose consciousness or even have a bump on my head.
It wasn’t until hours later that I started feeling fatigued and a bit off. A few days later, I thought I felt back to normal until I tried to work on my laptop — and the world started spinning. A pounding headache and intense brain fog followed, and then I knew I was dealing with a concussion.
“Many people who experience a concussion don’t actually feel any of the symptoms until hours later,” explained Dr. Daniel Daneshvar, the chief of Spaulding’s brain injury rehabilitation program and co-director of the Sports Concussion Clinic at Mass General Brigham.
Additionally, symptoms can “intensify or evolve over the first several days,” added Dr. Kevin Bickart, an assistant professor in neurology at the David Geffen School of Medicine at the University of California, Los Angeles.
Because of this, the criteria for diagnosing a concussion now include symptoms that appear within a 72-hour window, according to the 2023 American Congress of Rehabilitation Medicine.
