Genome-wide Association Study Identifies 30 Obsessive-compulsive Disorder Associated Loci.

Obsessive-compulsive disorder (OCD) affects approximately 1% of the population and has a strong genetic component. This study combined data from 53,660 OCD cases and 2,044,417 controls of European ancestry, identifying 30 genetic markers strongly associated with OCD and finding that genetic factors explain 6.7% of the risk. Separate analyses for different sub-groups of OCD, such […]

Non-linear Development Of EEG Coherence In Adolescents And Young Adults Shown By The Analysis Of Neurophysiological Trajectories And Their Covariance

Researchers studied brain wave patterns (EEG coherence) in a group of 1426 participants aged 12 to 31 in order to better understand how brain connections develop in teens and young adults. They looked at specific brain activity (high alpha frequency) across 27 pairs of brain regions, resulting in 5006 observations. Using statistical methods, they analyzed […]

Genome-wide Association Analyses Identify 95 Risk Loci And Provide Insights Into The Neurobiology Of Post-traumatic Stress Disorder

Post-traumatic stress disorder (PTSD) is a mental health condition that can develop after experiencing a traumatic event. It’s characterized by symptoms like intrusive thoughts, heightened arousal, avoiding reminders of the trauma, and negative changes in mood and thinking. For some individuals, these symptoms persist long after the traumatic experience has ended, significantly impacting their quality […]

The Amyloid Precursor Protein Modulates the Position and Length of the Axon Initial Segment

This study delves into the complex involvement of the amyloid precursor protein (APP) in Alzheimer’s disease (AD). While APP is primarily known for its connection to the production of β-amyloid (Aβ) peptides, a characteristic of AD brains, this research uncovers a different facet of its functionality. It reveals a unique link between APP and neuronal […]

Genomic Risk For Post-traumatic Stress Disorder In Families Densely Affected With Alcohol Use Disorders

Post-traumatic stress disorder (PTSD) is a condition that occurs after experiencing a traumatic event. Although many people are exposed to trauma, only a small percentage develop PTSD. Studies that look at the entire genome (genome-wide association studies or GWAS) have found specific genetic signs related to PTSD in both civilian and military groups. However, studies […]

Predicting Alcohol-related Memory Problems In Older Adults: A Machine Learning Study With Multi-domain Features

Researchers aimed to understand memory problems in older adults with a history of alcohol use disorder (AUD) using a machine learning approach. Comparisons were made between a group of 94 adults aged 50-81 with alcohol-induced memory problems (Memory group) to a matched Control group without memory issues. The Random Forests model identified specific features from […]
