Abstract

Background

This study aimed to investigate the potential presence of brain disorders, particularly hypoxia, via magnetic resonance imaging (MRI) in patients misusing methadone, with a comparison to regular opium users and a control group.

Methods

Conducted as a cross-sectional comparative study at Kamali Hospital in Karaj, Iran, the research included male participants comprising methadone users, opium users, and controls. Inclusion criteria were stringent, focusing on substance use duration and absence of brain structural disorders. MRI scans were performed using a 1.5T MRI scanner. Qualitative MRI assessments and chi-square tests analyzed associations between substance use and hypoxia, while logistic regression examined potential confounding variables.

Results

Significant hypoxia was observed in the methadone group (16.7%, 5/24; p = 0.00057), with no cases in the opium or control groups. Logistic regression analysis showed no significant predictors of hypoxia regarding dose and duration of use. MRI findings in methadone users with hypoxia included varied ADC intensities, high signal intensities on T2-weighted and diffusion-weighted imaging (DWI) sequences, and angiogenesis patterns on TOF sequences. The co-use of methadone and alcohol was noted in three of the five hypoxia cases.

Conclusion

Methadone misuse, particularly with alcohol, poses a significant risk of hypoxia, detectable via MRI. This study underscores the need for routine MRI monitoring, stricter regulation of non-prescribed methadone, and enhanced public health education to mitigate misuse risks. Future research should expand sample sizes and incorporate advanced imaging techniques to further elucidate methadone’s neurological impact.

Stumme Schlaganfälle − ein häufiger Nebenbefund im Kopf-CT?

In 4% der in der Notfallambulanz initiierten zerebralen Bildgebung sind „alte“ Schlaganfälle zu erkennen. Gar nicht so selten handelt es sich laut einer aktuellen Studie dabei um unbemerkte Insulte. Bietet sich hier womöglich die Chance auf ein effektives opportunistisches Screening?

CGRP-Antikörper auch bei älteren Migränekranken sicher

Beginnen ältere Migränekranke eine Prophylaxe mit CGRP-Antikörpern, kommt es anschließend nicht häufiger zu kardiovaskulären Problemen als unter einer Prophylaxe mit Botulinumtoxin. Darauf deutet eine US-Analyse von Medicare-Versicherten.

Frühwarnzeichen für multiple Sklerose bei Kindern und Jugendlichen

Ein Forschungsteam aus Deutschland und Kanada hat eine Reihe metabolischer, okulärer, muskuloskelettaler, gastrointestinaler und kardiovaskulärer Symptome identifiziert, die bei Kindern und Jugendlichen der Diagnose einer multiplen Sklerose (MS) vorausgehen können.

Migräne verstehen und psychotherapeutisch behandeln

Das Wissen über die Mechanismen, die im Gehirn bei einer Migräneattacke ablaufen, und mögliche Auslöser wird immer breiter. Der psychologische Psychotherapeut Dr. Dipl.-Psych. Timo Klan fasst den aktuellen Erkenntnisstand zusammen. Und er gibt Tipps für eine differenzierte, individuelle Diagnostik auch von Begleiterkrankungen und beschreibt erfolgreiche psychotherapeutische Interventionen.
