A major new study published this week suggests that a longstanding theory of mental depression has little to no evidence to support it.
The study, conducted by an international team of scientists and published in Molecular Psychiatry, argued that the “serotonin hypothesis of depression” is bolstered by “no consistent evidence” despite its popularity among psychiatrists for decades.
That hypothesis has held that depression is caused by what many psychiatrists have termed a “chemical imbalance” in the brain of those who suffer from it. The researchers said a broad review of multiple studies failed to establish that claim. Source: Just the News
