A Ketogenic Diet for Treatment-Resistant Depression This randomized clinical trial assesses the effect of a ketogenic diet on mental health outcomes in individuals with treatment-resistant depression.

Just out today, the keto diet showed a (modest) benefit in treatment resistant depression, when compared to a pretty reasonable control! jamanetwork.com/journals/jam...

Antidepressant treatment shouldn't be a guessing game. RELMED is working towards using advanced research to predict which medication is most likely to help each person along their individual path to recovery.

These posts are live now! Oxford is a great place to work. Do apply if you'd like to apply neurostimulatory techniques to understand symptoms.

Efficacy and target engagement of dopamine agonist pramipexole for anhedonic depression - the PRIME-PRAXOL randomized controlled trial Here, we examined the efficacy and target engagement of dopamine agonist pramipexole in treating a cross-diagnostic sample of mood disorders characterized by severe anhedonia.

Really interesting, brief ideas paper. Clearly relevant to treatment research-- the mechanism by which you leave an illness state is unlikely to just be the opposite of the mechanism by which you entered it (can see how this might apply to e.g. SSRIs in depression).

New preprint alert with @mikebrowning.bsky.social
and Chamith Halahakoon!
People have been using computer-based reinforcement learning tasks with affect probes. But to what extent do they reflect real-life affective experience? We tested this with 3 weeks of EMA + RL tasks in 339 participants.

Pramipexole vs. quetiapine vs. amantadine in TRD. Interesting open label, short term RCT using a surprisingly low dose (I suspect that the reported dose of 37.5mg of pramipexole is a typo and it should be 0.375mg)

It is generally higher than you see with ssris. This paper reports the odds of dropping out due to intolerance for lots of antidepressants vs placebo (page 154 of appendix). By comparison, the or in our study was 4.4.

GRATEFUL to @nihr.bsky.social for funding this work and @oxhealthbrc.bsky.social for support.
Pramipexole is clearly not a first line treatment for depression, but these results demonstrate that it can be a useful option for our most treatment-resistant patients! 6/6

TRANSPARENCY: There are challenges to using pramipexole: 20% stopped pramipexole due to side effects vs 5% placebo. Most common: nausea, headache, dizziness, sleep problems. 5/6

HYPOTHESIS: We targeted dopamine D2/3 receptors with pramipexole instead of the usual serotonergic approach. Dopamine is crucial for reward/pleasure - and anhedonia (can't feel pleasure) is often what persists even after other depression symptoms improve. 4/6

Background: About 30% of our patients don't respond to first-line antidepressants. We recruited people with chronic depression (median 8.5 years) who had tried 3-4 medications without success. These are the patients we struggle to help most. 3/6

FINDINGS: In our randomized controlled trial (n=150), patients receiving pramipexole showed:
• 6.4-point reduction in QIDS scores vs 2.4 for placebo (p<0.0001)
• 44% response rate vs 16% placebo
• 28% remission vs 8% placebo Effect size d=0.87 - this is substantial! 2/6
