Parkinson's disease is a progressive neurodegenerative disorder with increasing global prevalence, primarily driven by population ageing. A hallmark of the disease is the degeneration of nigrostriatal dopaminergic neurons, accompanied by marked activation of glial cells and a sustained neuroinflammatory response. Current pharmacological treatments are limited to symptomatic relief and do not...

OBJECTIVE: 'Ego dissolution' refers to a temporary state characterized by diminished self-referential processing, which leads to a breakdown of personal boundaries and an enhanced sense of unity with the environment.

Abstract Introduction Ayahuasca is a psychoactive brew used in Amazonian ceremonies, containing monoamine oxidase inhibitors (MAOIs) from Banisteriopsis caapi and N,N-dimethyltryptamine (DMT) from Psychotria viridis or Diplopterys cabrerana. Its global use has expanded for perceived antidepressant and anti-addictive effects. However, its MAOI content predisposes users to serotonergic toxicity...
