# Unveiling the Complex Interplay: Sudden Emergence of First‐Rank Schneiderian Symptoms Following TMS in a Patient With Severe Depression and Complex Trauma

## TL;DR

A 47-year-old man with depression and trauma developed sudden psychotic symptoms after TMS, likely due to a combination of medical, psychological, and environmental factors.

## Contribution

This case highlights a convergence model linking multiple factors to sudden psychosis after TMS in a high-risk patient.

## Key findings

- The patient developed first-rank symptoms and hallucinations after TMS and other stressors.
- Psychotic symptoms partially remitted after discontinuing TMS and initiating treatment.
- The case underscores the need for monitoring psychosis and suicide risk in high-risk TMS patients.

## Abstract

Schizophrenia‐spectrum disorders are characterized by psychotic symptoms, including hallucinations, delusions, and disorganized thinking. Schneider’s first‐rank symptoms (FRS)—including thought broadcasting and experiences of external control—are clinically salient but not ergonomic and require careful differential diagnosis. The emergence of new‐onset psychosis in midlife, particularly in individuals without prior psychotic history, warrants a broad biopsychosocial evaluation. We present the case of a 47‐year‐old male with chronic major depressive disorder and complex developmental trauma who developed abrupt FRS‐like phenomena (prominently thought broadcasting) and auditory hallucinations following a period marked by (1) severe pneumonia with lung abscess, (2) escalating anxiety and depressive distress, (3) exposure to substances including reported synthetic cannabinoids (“Spice”) with a urine toxicology positive for amphetamines, and (4) neuromodulation via 20 sessions of transcranial magnetic stimulation (TMS). Concurrently, the patient experienced a severe psychosocial/legal stressor (investigation related to child sexual exploitation material), associated with profound shame and fear. Rather than attributing symptoms to a single trigger, this case highlights a convergence model—medical inflammation, substance toxicity, trauma‐related vulnerability, and acute legal stress—potentially disrupting cerebral homeostasis and precipitating psychosis and suicidality. Treatment included discontinuation of TMS, pharmacologic stabilization, and intensive psychotherapy, with partial remission of psychotic symptoms. There is a need for structured monitoring for emergent psychosis and multidimensional suicide risk in high‐risk patients receiving neuromodulation.
