Psychiatric disorders remain a leading cause of disability worldwide, and current treatments based on monoaminergic modulation often have limited efficacy and high relapse rates. This review synthesizes evidence from three advancing fields to propose an integrated model for psychiatric pathophysiology and treatment. Neuroinflammation—chronic activation of the brain's innate immune system—is identified as a key transdiagnostic mechanism in major depression, anxiety, and schizophrenia. The microbiota-gut-brain axis is highlighted as a bidirectional communication network that regulates systemic immunity and drives neuroinflammation through increased intestinal permeability and dysbiosis.
A 30-year-old female social media influencer developed the Truman Show Delusion, believing her life was a fabricated reality show live-streamed via hidden cameras with strangers and family members as co-conspirators. The delusion emerged after a decline in online engagement and a personal conflict, accompanied by paranoia, anxiety, and referential delusions. Treatment with antipsychotic medication (risperidone), supportive therapy, and structured digital hygiene led to significant symptom improvement within three weeks. The case illustrates how contemporary culture and digital lifestyles, particularly the intertwining of identity and self-worth with online validation, shape the phenomenology of psychosis. It also highlights the diagnostic challenge of distinguishing pathological delusions from normative influencer behaviors, emphasizing the need for clinicians to recognize technology-themed psychotic symptoms.
