Keynote webinar | Spotlight on sleep in brain health

LIVE: Thursday 2nd May 2024, 18:00-19:30 (CEST)

Quality sleep is essential for health. But what happens to our brains when sleep patterns are disturbed? Join our experts to explore the interplay between sleep disruption and neurological diseases, and the questions that you need to be asking your patients to help you prevent the harmful effects of sleep deprivation.

Abstract

Purpose

An increasing number of heroin addicts—especially young and first-time users—prefer inhaling the drug to intravenous injection. A rare complication of inhaling heroin is the development of a spongiform leukoencephalopathy (HSLE).

Methods

Pathological background, symptoms, imaging, and therapeutical options are discussed on the basis of an example case.

Results

Pathophysiologically, a dysfunction of the oligodendrocyte mitochondria is suspected. Three distinct stages based on key symptoms are defined. Patients may remain in one stage, or pass through two, or all three stages. Magnetic resonance imaging (MRI) is necessary for diagnosis. There are few therapeutical options. Antioxidants and coenzyme Q may be beneficial. The disorder is self-limiting in the majority of cases. Complications such as hydrocephalus and diffuse cerebellar swelling may, however, require neurosurgical intervention.

Conclusions

HSLE is a rare occurrence in patients with heroin abuse. The number of undetected cases in drug-related deaths may be high. Clinical appearance may be easily mistaken for withdrawal symptoms.
