As people age, neuropsychological health often deteriorates, leading to a higher prevalence of age-related depression. Symptoms may include anxiety, apathy, mood instability, sadness, and, in severe cases, suicidal thoughts. Depression in the elderly is a widespread concern, and conventional treatments such as antidepressants are often limited by side effects, reduced efficacy, and complications arising from polypharmacy. In response, novel therapeutic approaches are being explored, including psychedelic interventions. Recent clinical and preclinical studies suggest that psychedelics could offer a promising treatment for major depressive disorder (MDD) in older adults. These compounds, known for their profound neurobiological effects, have gained attention for their potential to address depression where traditional therapies fall short. This review aims to examine the therapeutic promise of psychedelic substances, focusing on those that show potential for treating MDD in the elderly. We also explore the underlying mechanisms through which psychedelics may exert their effects and highlight the preclinical models that support their use.

To address this, we developed a machine learning method based on a Bayesian hierarchical model to quantitatively infer latent decision-making parameters from behavioural data collected during a trust game. Applying this method to data from patients with major depressive disorder (MDD) and healthy controls (HCs), we estimated individualised model parameters that regulate trust-related decisions. The model successfully predicted participants' behaviours in the task. Although no significant group-level differences were observed in the estimated parameters between the MDD and HC groups, we uncovered hidden links between trust-related decision-making processes and specific blood biomarkers. Notably, metabolites such as 5-aminolevulinic acid, acetylcarnitine, and 2-aminobutyric acid were significantly associated with individual differences in trusting behaviour.

Observational studies confirm the persisting high rate of antipsychotic OLU prescription in two out of three youths and 30-60% of adults using antipsychotics. Increasing rates of low-dose quetiapine prescriptions for anxiety or sleep symptoms are paradigmatic of the current public health concern regarding antipsychotic OLU. Such prescriptions receive impetus from industry-funded marketing strategies and prescribers' feeling of innocuousness, with a resulting underestimation of the risk of adverse drug reactions (ADR). However, antipsychotic OLU should be neither trivialised nor demonised since it may be the only therapeutic option in persons with resistant psychiatric disorders or serious ADR with labelled drugs.
