    Human and animal studies suggest an intriguing link between mitochondrial diseases and depression. Although depression has historically been linked to alterations in monoaminergic pharmacology and adult hippocampal neurogenesis, new data increasingly implicate broader forms of dampened plasticity, including plasticity within the cell. Mitochondria are the cellular powerhouse of eukaryotic cells, and they also regulate brain function through oxidative stress and apoptosis. In this paper, we make the case that mitochondrial dysfunction could play an important role in the pathophysiology of depression. Alterations in mitochondrial functions such as oxidative phosphorylation (OXPHOS) and membrane polarity, which increase oxidative stress and apoptosis, may precede the development of depressive symptoms. However, the data in relation to antidepressant drug effects are contradictory: some studies reveal they have no effect on mitochondrial function or even potentiate dysfunction, whereas other studies show more beneficial effects. Overall, the data suggest an intriguing link between mitochondrial function and depression that warrants further investigation. Mitochondria could be targeted in the development of novel antidepressant drugs, and specific forms of mitochondrial dysfunction could be identified as biomarkers to personalize treatment and aid in early diagnosis by differentiating between disorders with overlapping symptoms.

    Another recent paper looked at the effect of "inflammation" on depression. Mine was fairly definitively caused by the blood glucose fluctuations leading to huge dumps of counterregulatory hormones including cortisol, epinephrine and norepinephrine which may explain why it responded poorly to SSRIs (not uncommon) and well to Venlafaxine and tricyclics. Once I nailed my glucose I came off years of medication.

    Yes I suspect mitochondria are involved in a lot of things, almost certainly including ME/CFS.

    Peter at Hyperlipid is a fine source of information and there was an interesting blog post by Michael Eades looking at the effects of Omega 6 oils vs. other (saturated) fats on mitochondria
