How brain trauma can be treated, but can it lead to suicide?
A California woman is in intensive care after her brain was injured in a fight with a group of people in the United States.
Her fiance said the fight was over a dispute over money.
She has been in critical condition at a San Francisco hospital.
The fiance, whose name was not released, told the Associated Press that his fiance was punched in the face.
He said his fiance had been at the table with friends.
He was knocked out, and his friend went in to help.
The person he was with was not hurt, but he was bleeding profusely, said the fiance, who has been hospitalized with an undisclosed illness.
The California Department of Public Health said it has treated one case of brain trauma in the county.
