A research review in the New England Journal of Medicine highlights the growing concern over cannabis use disorder, exacerbated by increased cannabis potency and usage. This disorder, affecting a significant portion of Americans, particularly young adults, is often accompanied by other psychiatric conditions.

by Holly Moody-Porter, University of Maryland School of Medicine Credit: Yash Lucid from Pexels The widespread use of cannabis (marijuana) and its increased potency are associated with a rise in cannabis-related psychiatric conditions, according to a new University of Maryland School of Medicine (UMSOM) review article that was published in the New England Journal of Medicine....
Researchers at the University of Toronto are inching closer to realizing a life-saving brain cancer treatment by using gold nanoparticles to make radiation therapy more effective and less toxic for patients. In their battle against glioblastoma multiforme (GBM), a rare, fast-growing cancer that begins in the brain, the multidisciplinary team has discovered that the nanoparticles can keep...
by The Mount Sinai Hospital Graphical abstract. Credit: Cell Reports (2022). DOI: 10.1016/j.celrep.2022.110877 Researchers from the Icahn School of Medicine at Mount Sinai have applied a novel stem cell model to map disease risk variants in human neurons, which could help provide insights into the biological mechanisms that underlie neuropsychiatric disorders such as autism and schizophrenia. The...
A new study in macaque monkeys has shed light on which parts of the brain support credit assignment processes (how the brain links outcomes with its decisions) and, for the first time, how low-intensity transcranial ultrasound stimulation (TUS) can modulate both brain activity and behaviours related to these decision-making and learning processes. While currently developed in an...

In a new study, scientists from Forschungszentrum Jülich and Heinrich Heine University Düsseldorf (HHU) have demonstrated for the first time that improper protein conformation is linked to the development of...

by The Mount Sinai Hospital Credit: The Mount Sinai Hospital Mount Sinai researchers have identified a neural pathway through which the brain detects errors and guides subsequent behavioral improvement. This process, called cognitive control, is frequently dysregulated in a wide range of psychiatric disorders. The team’s research, published February 19 in Neuron, also suggests that neurostimulation of this brain pathway...
COLUMBUS, Ohio – New research suggests mindfulness training may help multiple sclerosis patients in two very different ways: regulating negative emotions and improving processing speed. People with MS who underwent the four-week mindfulness training not only improved more compared to those who did nothing – they also improved compared to those who tried another treatment,...
