A teenager has been convicted of attacking a father-of-four, causing him to hit his head and fall unconscious.
Phil Carroll underwent major surgery to remove a blood clot
The 16-year-old punched Phil Carroll after the 49-year-old argued with a group of youths close to his home in Salford, Greater Manchester.
Mr Carroll suffered serious injuries when he fell backwards, hitting his head on the floor.
The teenager, who cannot be named, was convicted by Salford magistrates of assault causing grievous bodily harm.
He had denied the charge but District Judge John Finestein rejected his claims of self defence, convicted him and told him he could face jail.
Mr Carroll suffered swelling to the brain, underwent major surgery to remove a blood clot and some bone from his skull and fell into an 18-day coma.
He is now at home, but still needs treatment. He has spoken about his recovery and says he was "over the moon" that the youth had been convicted.
He said: "It has made me very angry and bad-tempered. I don't remember bringing my children up, it has been very hard for me.
"I just have no interest in anything or anyone. I remember being at the birth of my first son and my first daughter, the other two I don't remember.
"The doctors say it could get better over the next year or two. I am hopeful I will get better."
The attack happened on 13 May when Mr Carroll was working on his car with his brother John on land at the back of his home on Grecian Street North in Salford.
One of a group of youths threw a stone towards Mr Carroll's land which hit the garage door and landed on his car.
Mr Carroll and his brother ran down the alleyway and the 49-year-old grabbed hold of the youth responsible.
John Perris, prosecuting, told the court the defendant came from the group and punched him.
Mr Carroll said he hoped the conviction of his attacker would give him some sort of "breakthrough".
He said: "I was over the moon when I heard that the person that did this to me was found guilty.
"I had tears in my eyes it had all gone the right way. I would like to see him thrown in jail for at least a few years."
The youth will be sentenced next month.
