Brain Damage in Schizophrenia May Begin in Specific Neural Epicenters

New brain imaging research shows that structural damage in schizophrenia spectrum disorders may begin in specific “epicenter” regions before spreading across connected brain networks. Individuals with the condition showed widespread reductions in structural similarity between key cognitive and emotional brain regions.

AI Uncovers Hidden Stress Damage in the Body

Researchers developed an AI tool that detects chronic stress by measuring adrenal gland volume on routine chest CT scans. This biomarker aligns with cortisol levels, stress questionnaires, and future cardiovascular outcomes, offering the first imaging-based method to quantify stress load in the body.

Young Adults With Obesity Show Early Signs of Brain Stress

New research shows that young adults with obesity already display biological patterns associated with liver stress, chronic inflammation, and early neural injury—changes typically seen in older adults with cognitive impairment. Participants with obesity also had unusually low blood choline levels, a nutrient critical for liver function, inflammation control, and long-term brain health.

Your Brain Has a Built-In Isolation Mode

New research uncovers the exact immune-to-brain pathway that drives the loss of social motivation during sickness. Scientists showed that when the cytokine IL-1β binds to receptors on neurons within the dorsal raphe nucleus, it activates a circuit that reduces social interaction.

Untreated Sleep Apnea Doubles Parkinson’s Risk

A large analysis of more than 11 million medical records found that people with untreated obstructive sleep apnea face a substantially higher risk of developing Parkinson’s disease over time. Even after accounting for factors like age, obesity, and cardiovascular conditions, those who did not use CPAP were nearly twice as likely to be diagnosed with Parkinson’s as those who treated their apnea.

Gene Discovery Reveals Hidden Risk Pathway for Delirium

A massive genetic analysis of over one million people has revealed that APOE, long known for its role in Alzheimer’s disease, also independently increases a person’s risk of delirium. The researchers found that this effect cannot be explained solely by dementia, showing that APOE directly contributes to delirium vulnerability in otherwise cognitively healthy individuals.

Genetics Point to a New Type of Suicide Risk

New research shows that many people who die by suicide without prior suicidal thoughts or behaviors are not simply “missed cases”—they may have an entirely different underlying risk profile. Genetic analyses of more than 2,700 deaths revealed that these individuals carry fewer genetic risk factors for major psychiatric conditions compared to those with known suicidality.

Stress-Like Behaviors Traced to a Single ATP Circuit in the Brain

New research reveals that reduced ATP signaling in the hippocampus plays a causal role in both depression- and anxiety-like behaviors. In stressed male mice, ATP levels and the ATP-releasing protein connexin 43 were markedly lower.

Psychedelic ‘Ego Death’ Tied to a Collapse in Alpha Brain Waves

A new study using DMT as a scientific tool reveals how psychedelics alter the brain’s alpha-wave dynamics and weaken our sense of self. The researchers found that DMT pushes the brain away from its usual “critical” balance between chaos and order, a state believed to be essential for coherent self-awareness over time.

One in Two Americans Have Neurological Disorders

A comprehensive national analysis shows that over 180 million Americans—more than half the U.S. population—are living with a neurological disease or disorder. These conditions span the lifespan, from neurodevelopmental disorders to migraines to age-related diseases such as Parkinson’s and Alzheimer’s.

Genetics Plus Heart Health Markers Sharpen Dementia Risk

New research shows that dementia risk is best predicted by combining genetic vulnerability with cardiovascular disease markers, revealing a more precise and actionable way to identify who is most likely to develop the condition. While genes such as APOE4 and family history contribute heavily, equally powerful are modifiable factors like hypertension, obesity, and diabetes.

Supplement Shows Promise in Blocking Amyloid in Alzheimer’s

A new study shows that oral arginine, a naturally occurring amino acid, can significantly suppress amyloid-β aggregation in Alzheimer’s disease models. Researchers found that arginine not only prevented Aβ42 from clumping but also reduced plaques and inflammation in mouse and fruit fly models carrying Alzheimer’s-related mutations.
