There has been a breakthrough in the area of depression, with new research uncovering genetic links to the illness.
Scientists from the University of Queensland, working with other international academics, have managed to pinpoint 269 genes linked to depression, along with 87 genetic changes.
This extended from a decade-long study involving more than 800,000 - of which, approximately 250,000 had been diagnosed with depression.
Dr Maciej Trzaskowski, one of the authors of the study, has said that this breakthrough has the capacity to help treat depression more effectively.
"This is one of the main things, the whole population of humanity show some type of risk for depression, but the severity of that condition obviously varies from individual to individual," Dr Trzaskowski said.
"Some will have a very high risk of developing depression so any sort of environment triggers might lead them into the path of developing depression."
