Neural Biomarker for OCD Identified

Researchers discovered a neural activity pattern that can accurately predict and monitor the clinical status of OCD patients undergoing deep brain stimulation (DBS). The study highlights how this biomarker can guide DBS therapy, improving treatment outcomes for those with severe, treatment-resistant OCD.

Astrocytes Play Critical Role in Regulating Behavior

Researchers made a groundbreaking discovery in identifying a unique group of astrocytes, located in the brain's central striatum, that play a crucial role in regulating behaviors linked to neuropsychiatric disorders. This distinct subset of astrocytes expresses the gene Crym, coding for μ-crystallin, a protein associated with various human diseases.

OCD Linked to Higher Mortality Risks

A new study highlights a concerning link between obsessive-compulsive disorder (OCD) and an increased risk of death from both natural and unnatural causes. The study, using data from over 60,000 people with OCD, shows an 82% higher overall mortality risk compared to those without the disorder.

This shows a person washing their hands.

Reshaping the OCD Brain: How Therapy Alters Neural Connectivity

A new study reveals that exposure and response prevention (EX/RP), a primary therapy for obsessive-compulsive disorder (OCD), effectively reshapes brain connectivity. This therapy enhances cognitive control by strengthening connections within key neural networks. Using advanced MRI techniques, researchers observed significant changes in the frontoparietal, cingulo-opercular, and default mode networks among OCD patients who underwent EX/RP compared to those who received stress management training.

Brain Chemical Imbalance Detected in OCD

Researchers discovered a neurochemical imbalance in the brains of patients with Obsessive-Compulsive Disorder (OCD). Using magnetic resonance spectroscopy, they found a disrupted balance between neurotransmitters glutamate and GABA in two specific regions of the frontal lobes.

Microglia’s Role in Controlling Anxiety and OCD

A new study reveals how microglia can regulate anxiety and obsessive-compulsive spectrum disorder (OCSD) behaviors. Traditionally overlooked in favor of neurons, specific microglia populations were found to both stimulate and suppress these behaviors, thus acting as both a "brake" and "accelerator".

Learning Behavior Differs Between OCD and Problem Gambling

When the reward is less than expected, people with OCD exhibit lower-than-normal learning rates. Conversely, those with gambling addictions exhibit boosted and blunted patterns of learning when the rewards are higher and lower than expected.
