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.

Overall, the results challenge the idea that motivational symptoms universally impair decision-making. In the paper, we discuss potential reasons for this surprising finding. We are very happy to hear your thoughts, and please share!

…but in actual decision-making, they showed enhanced goal-directed performance: Higher apathy-anhedonia scores were related to greater sensitivity to goal values – plus faster navigation to goals and higher earnings. (n.b. this relationship was not found in other common tasks we also collected.)

The paradigm tries to capture features of real-world decision-making: 1) we often make choices in well-learned envirornments, 2) risk is learned from experience, and 3) plans with more steps are riskier, but can also be more rewarding

Elliott Wimmer @elliottwimmer.bsky.social · 20/08/2025
We designed a novel risky goal task: over two days, participants learned maze-like environments where each step carried a small risk of failure. As goals became more distant, risk compounded. Participants then made choices between a certain reward vs. risky goals with variable distance & reward.

Across 3 studies (1 preregistered), combined n>600, using 2 different RL tasks, we found that performance was positively correlated with anhedonia symptoms. General depression effects were mixed, but no correlations were negative. These results are unexpected so we look forward to feedback!

Reconstructing a new hippocampal engram for systems reconsolidation and remote memory updating
This study demonstrates that hippocampal activity during remote recall is crucial for the reconsolidation of remote memory, also called systems reconsolidation, with new hippocampal engram cells recruited to enable memory updating. The findings reveal that adult neurogenesis supports this recruitment process and the role of mPFC projections to the hippocampus and amygdala in systems reconsolidation.

Interesting work showing quite low test-retest reliability in a very common reward learning task, with relevance for computational psychiatry. It suggests, as other research has hinted, that feedback learning tasks – with rapid & massed repetitions – are not an all-purpose solution.
