Summary

This study will follow 200 adults in Egypt who have psychosis to compare two conditions: schizophrenia and psychosis caused by methamphetamine use. Researchers will assess symptoms, treatment response, and recovery over three months. The goal is to improve diagnosis and understand how these conditions differ.

What this could mean

Our plain-language read of the trial. This is informational only, not medical advice or a prediction.

What this could lead to
If successful, this study could help doctors better distinguish between methamphetamine-induced psychosis and schizophrenia, leading to more accurate diagnoses and tailored treatments.
What could go wrong
This is an observational study, not a treatment trial, so it won't directly improve patient care. Results may not apply outside Egypt or to other populations.
