Ayahuasca, a psychotropic infusion made from Amazonian plants, can induce psychotic episodes as a side effect. A patient who experienced such an episode after consuming ayahuasca was successfully treated with antipsychotic medication. The case underscores the need for better understanding and regulation of ayahuasca's social-legal status, further research, and psycho-education to raise awareness of its potential risks.

A 26-year-old man developed a psychotic episode after consuming ayahuasca for the first time during a ritual ceremony. Symptoms included behavioral changes and delusions that worsened over seven months before he required psychiatric hospitalization. He responded well to antipsychotic medication and was discharged with outpatient follow-up. Although psychosis induced by ayahuasca is rare, increasing access to the substance makes such cases more important to recognize.

Cognitive science emerged in the mid-20th century as a multidisciplinary field uniting diverse approaches to studying the human mind and knowledge. This theoretical paper critically examines how theoretical biology has addressed cognition, focusing on the enactive project and Francisco Varela's neurophenomenology. It traces the history of cognitive science, the rise of the enactive paradigm, and the "embodied" turn influenced by continental phenomenology. The authors argue that the "hard problem" of consciousness persists due to reductionist views that treat cognition as rational, individual, abstract, and disembodied, reinforcing functionalism in philosophy of mind. They contend that resolving classic dichotomies in mind sciences requires rejecting such assumptions.

Ayahuasca, a psychotropic beverage from South America containing β-carbolines and DMT, can cause poisoning, especially when combined with other drugs. A 24-year-old male habitual user arrived at an emergency room with cognitive decline, delirium, stupor, and disorientation. Blood analysis identified DMT, harmaline, harmine, harmol, bufotenine, and tetrahydro harmine, along with other narcotics including a cannabis metabolite, amphetamine, and norcocaine. The poisoning was associated with ayahuasca consumption and its interaction with other drugs.

A 55-year-old man who had received a heart transplant for heart failure of ischemic origin developed depressed mood, anhedonia, and suicidal ideation six months after the transplant, scoring 20/27 on the PHQ-9 depression screening scale. After a week of mirtazapine 30 mg/night left him at high suicide risk, a 24-hour ketamine infusion produced significant mood improvement and disappearance of suicidal ideation within 24 hours. Depression in transplant patients is associated with graft loss, post-transplant mortality, and other negative outcomes such as deep vein thrombosis. Ketamine infusion was an effective and safe option for treating major depression with suicidal risk in this heart transplant patient.

The longstanding division between the natural sciences, which aim at explanation, and the social sciences, which aim at understanding or interpretation, is being challenged by interdisciplinary work on the emergence of the mental within intersubjective relationships. Phenomenology's concept of intersubjectivity as an embodied practice now finds support from cognitive neuroscience and developmental psychology. Authors like J. Bruner and S. Gallagher propose such collaboration as a way to integrate the traditions of explanation and understanding. This paper analyzes how far this collaboration, especially on understanding others and its relevance for psychopathologies, has closed the gap that opened in the nineteenth century between these traditions.
