Reading of the Week: Amphetamines & ED Visits – the New CJP Paper; Also, Psilocybin for Depression (QT) and Anti-NMDAR Encephalitis (CMAJ)

From the Editor

Agitated, excited, violent – when intoxicated. But my patient is also pleasant and engaging when not using substance (crystal methamphetamine).

Amphetamine use seems more and more common. What does the data show? In a new paper for The Canadian Journal of Psychiatry, James A. G. Crispo (of the University of British Columbia) and his co-authors look at amphetamine-related ED visits in Ontario. Drawing on administrative databases, they find a sharp rise over time: a 15-fold increase between 2003 and 2020. They write: “Increasing rates of amphetamine-related ED visits in Ontario are cause for concern.”

In the second selection, Dr. Ishrat Husain (of the University of Toronto) comments on psilocybin and depression in a new Quick Takes podcast. He goes into detail on the new NEJM study – which he co-authored. Dr. Husain discusses the literature and unanswered research questions. “It’s not necessarily all sunshine and rainbows.”

And in the third selection, Dr. Candace Marsters (of the University of Alberta) and her colleagues consider the unusual presentation of young adult with first-episode psychosis in a new paper for CMAJ. With time and diagnostic testing, they conclude that she has anti-N-methyl-D-aspartate receptor (NMDAR) encephalitis, and offer observations about that diagnosis and the limitations of testing. “Anti-NMDAR encephalitis is a rare but important differential diagnosis of first-episode psychosis among young adults.”

Reading of the Week: Psilocybin for Depression – The New NEJM Paper

From the Editor

Is this the breakthrough we have been waiting for?

This week, we look at the new study from The New England Journal of Medicine considering psilocybin (a naturally occurring psychedelic compound found in some mushrooms) and escitalopram for depression. The paper, written by Robin Carhart-Harris (of Imperial College) and his co-authors, has received much attention. One online news source quipped: “Tripping may be as effective as your antidepressants.”

In this study, psilocybin was compared to the SSRI with a double-blind, randomized, controlled trial. Carhart-Harris et al. find: “On the basis of the change in depression scores on the QIDS-SR-16 at week 6, this trial did not show a significant difference in antidepressant effects between psilocybin and escitalopram in a selected group of patients.”

We consider the paper and the editorial that runs with it by Dr. Jeffrey A. Lieberman (of Columbia University). We also ask Dr. Ishrat Husain (of the University of Toronto) for his thoughts. Finally, we mention other cutting-edge treatments.
