Diakite left the UK nearly two weeks ago and according to reports on Friday morning is being treated for depression by the club's medical team.
However, a source has revealed that the 23-year-old Malian international, who is in regular contact with QPR, is dealing with a delicate personal matter and is not battling depression.
Diakite played in the opening two matches of the season, but missed Saturday's 3-1 defeat by Manchester City.
QPR manager Mark Hughes announced in a statement released last Thursday that Diakite had been granted compassionate leave.
"We hope he can overcome this very quickly and get back to being the outstanding player that he undoubtedly is," Hughes said.
"In the meantime, we are giving him the time and help that he needs."
Diakite arrived at Loftus Road on loan from Nancy in January and helped QPR avoid relegation by scoring the winning goal in their 2-1 victory over Arsenal in March.
The transfer was made permanent in June with the defensive midfielder, who was born in France but has won five caps for Mali, costing in the region of ?3.5million.
