The teenager from Malmö lashed out at his mother and, according to the prosecution, inflicted life-threatening injuries. She managed to flee the scene and take refuge with a neighbour.
Her son raised the alarm himself and rang the police saying; "I don't know how to say it...I have tried to kill my mother," he was quoted as saying in the indictment.
Local newspaper Skånskan reported that the mother and son had a row over how much time he was devoting to playing computer games. He claimed that his mother referred to him as "useless" and that he snapped as a result.
"I just blacked out. We had rows and the like so I took a knife and stabbed her a few times," the teen said.
His mother was taken to hospital nursing stab wounds to her face and arms. She had also suffered three stab wounds to her back. Police confiscated a 23 centimetre long kitchen knife and arrested the boy at the scene.
The boy's mother said she was angry with her son for playing too many video games and neglecting his school work. On the day of the attack he was home from school due to illness, with his mother saying she was surprised he could play games for so long if he was ill.
He claimed that he sometimes played computer games for two to three hours, and other days not at all, reported Skånskan.
In January a 16-year old was arrested for attacking his mother with a hammer in Gothenburg.
