Former Assembly Member Carl Sargeant had a "history of depression".
A pre-inquest hearing into his death at Ruthin's Coroner's Court today, heard that Mr Sargeant had been taking anti-depressants at the time he was found dead.
There was no suggestion of an overdose, however.
Mr Sargeant’s son Jack, who became Assembly Member following the Alyn and Deeside AM’s death last November, was present at the hearing.
The inquest also heard that the First Minster is to be called as a witness at the inquest.
Today Carwyn Jones was not present, but had legal representation.
The provisional cause of death was hanging, a previous inquest has heard.
Mr Sargeant was found dead at his home in Connah's Quay four days after being sacked by the First Minister.
The final inquest date is yet to be fixed.
