BERLIN, Oct. 20 (UPI) — German doctors said a man who was without oxygen for 15 minutes later began having seizures — but only while playing Sudoku.
The doctors, writing in the journal JAMA Neurology, said the 25-year-old student was deprived of an adequate supply of oxygen for 15 minutes when he was buried by an avalanche while skiing.
The man later discovered he suffered from myoclonus, involuntary jerking, in his mouth and legs, but his arms were unaffected.
The authors of the study said the man began experiencing seizures weeks after the incident when he started trying to solve Sudoku puzzles.
The man’s seizures “stopped immediately when the Sudoku puzzle was discontinued,” the doctors wrote.
The researchers said the lack of oxygen likely caused damage to specific areas of the man’s brain.
“Similar seizures could be elicited by other visual-spatial tasks like sorting random numbers in an ascending order, but not by reading, writing or calculating alone,” they wrote.
The doctors said the man quit attempting Sudoku puzzles and has now been without seizures for five years.
