Experts who reviewed the case of a 15-year-old schoolboy who took his own life have raised concerns about his treatment and diagnosis, an Adelaide inquest has been told.
Deputy State coroner Anthony Schapel on Monday began hearing the inquest into the death of Jason William Hugo-Horsman who died at his Mt Barker home on October 9, 2010.
Counsel assisting Tim Griffin said that in the lead-up to Jason's death, he struggled with issues including school, anxiety and depression, anger management and a decline in his mental health.
Witnesses would include his social worker, his school counsellor and a child psychiatrist who treated him.
Mr Griffin said the coroner also would see notes said to have been written by Jason and statements of friends to whom he apparently indicated his intention to take his life.
Two experts "will express their own concerns about the diagnosis and levels of treatment afforded to Jason", he said.
But he noted that a great deal of information about Jason's state of mind was not discovered until after his death.
The sources included hand written notes, pictures and Facebook entries.
Jason's father will be the first witness.
