Sep 25th 2023, 19:05

New research is painting a clearer picture of the early signs of multiple sclerosis (MS), showing that people are nearly twice as likely to experience mental illness in the years leading up to the onset of the diseases. The study suggests that psychiatric conditions like anxiety and depression may be part of a prodromal phase of MS -- a set of preliminary symptoms and clues that arise before classic MS symptoms.

( Marker for brain inflammation finally decoded
Sep 25th 2023, 12:48

Inflammation is the sign that our body is defending itself against an aggression. But when this response escalates, for example in the brain, it can lead to serious neurological or psychiatric diseases. A team investigated a marker protein targeted by medical imaging to visualize cerebral inflammation, but whose interpretation was still uncertain. The team reveals that a large quantity of this protein goes hand in hand with a large quantity of inflammatory cells, but its presence is not a sign of their overactivation. These results pave the way for optimal observation of neuroinflammatory processes and a re-reading of previous studies on the subject.

( Posttraumatic brain activity predicts resilience to PTSD
Sep 21st 2023, 15:45

After a traumatic experience, most people recover without incident, but some people -- between 2% and 10% -- develop posttraumatic stress disorder (PTSD), a mental health condition that can cause debilitating symptoms of anxiety due to emotional dysregulation. PTSD symptoms are present in up to 40% of trauma survivors in the acute aftermath of trauma, but full-blown PTSD develops in only a small subset of cases. Early identification of those at risk is critical for both early treatment and possible prevention.

( Suppressing negative thoughts may be good for mental health after all, study suggests
Sep 20th 2023, 15:23

The commonly-held belief that attempting to suppress negative thoughts is bad for our mental health could be wrong, a new study suggests. Researchers trained 120 volunteers worldwide to suppress thoughts about negative events that worried them, and found that not only did these become less vivid, but that the participants' mental health also improved.

( Inflammatory signs for adolescent depression differ between boys and girls
Sep 13th 2023, 12:27

( New neural insights into processing uncertainty in obsessive-compulsive disorder
Sep 12th 2023, 16:56

Obsessive-compulsive disorder (OCD) is a neurological disorder characterized by repeated behaviors such as cleaning and checking despite clear objective evidence of cleanliness, orderliness, and correctness. Although the disease is often mischaracterized as a disorder of 'fussiness,' the disorder actually stems from difficulty in processing uncertainty. However, the neural underpinnings of that aberrant processing remains unknown. Now, a new study uses brain imaging to get a closer look at the underpinnings of uncertainty processing in OCD.

( Your body's own cannabinoid molecules calm you during stress
Sep 12th 2023, 11:35

When you're under stress, your brain may release its own cannabinoid molecules to calm you, activating the same brain receptors as THC derived from cannabis plants. But the brain activity regulated by these cannabinoid molecules were not well known. A new study in mice has discovered a key emotional brain center, the amygdala, releases cannabinoid molecules under stress that dampen the incoming stress alarm from the hippocampus, a memory and emotion center in the brain. The finding may reveal novel therapeutic targets for the treatment of stress-related disorders.
