“you can’t let your mental health affect everything” sorry. my bad. i forgot that even though my mental illness is In My Brain, which does Everything for me, that’s not an excuse for my mental health affecting everything i do. so sorry.

Mitochondria are the vital organelles that deliver energy to all
cells and mitochondrial damage has been found, for example, in brain
imaging of bipolar patients and in post-mortem brains. Roughly 20% of
patients with mitochondrial disease also have bipolar disorder, a major
psychiatric disease characterized by manic and depressive episodes.
Altered serotonin functioning, on the other hand, seems to be involved
in bipolar disorder because drugs that target serotonin levels can
effectively treat the condition. “Our study suggests that mitochondrial
dysfunction can alter activity of serotonergic neurons in bipolar
disorder, and this is the first time these two lines of evidence have
been linked,” says Tadafumi Kato, research group leader at CBS. The
research was published in the journal Molecular Psychiatry.
The study started by identifying ANT1 mutations in patients with bipolar disorder. Kato and colleagues then looked at mice lacking the ANT1
gene in the brain only. Compared with non-mutant mice, the mitochondria
in these knockout mice could not retain calcium and had leakier pores.
The ANT1-mutant mice also showed lower impulsivity in behavior
tests, and consistent with this, their brains showed elevated serotonin
turnover. This hyper-serotonergic state is likely a result of a cascade
of changes that starts with the loss of the ANT1 gene and the
resulting dysfunctional mitochondria. Enhanced serotonergic activity may
then further impair mitochondria in a vicious cycle.
Serotonergic neurons were found to deteriorate in a brain area called
the dorsal raphe, which is a region also affected in Parkinson’s
disease—another condition that may have its roots in mitochondrial
dysfunction. The ANT1 mutation does not cause bipolar disorder,
says Kato, but is associated with elevated risk. The implication of
this research is that emerging therapies for the underlying
mitochondrial dysfunction could one day treat bipolar disorder more
successfully than today’s variable serotonin-targeting drugs.

Tove Jansson’s illustrations of J.R.R Tolkien’s “The Hobbit”
It was Astrid Lindgren, author of the universally beloved Pippi Longstockings, who as an editor and publisher by the Stockholm publishing house Rabén & Sjögren approached Tove and asked her to illustrate the Swedish edition of The Hobbit.
