Music After Learning Boosts Memory, But Only at the Right Emotion Level. Researchers have found that listening to music after an experience can sharpen memory, but only when the emotional response to the music is at a moderate level. Volunteers who felt balanced levels of

High-THC Cannabis Linked to Psychosis and Addiction. A broad review of 99 studies found that high-potency THC cannabis products are consistently linked to higher risks of psychosis, schizophrenia, and cannabis use disorder. Evidence on anxiety and depression was mixed, with

Blood Flow Dynamics Reveal Early Signs of Alzheimer’s Disease. A new diagnostic tool that measures how the brain regulates blood flow may provide a safer and more accurate way to detect Alzheimer’s disease. Using Doppler ultrasound and near-infrared spectroscopy, researchers

“Life Purpose Lowers Risk for Cognitive Impairment in a United States Population-Based Cohort” by Aliza Wingo et al. American Journal of Geriatric Psychiatry.

Key Findings:. 28% Lower Risk: Adults with a stronger sense of purpose were significantly less likely to develop dementia or cognitive impairment. Consistent Across Groups: The protective effect held across racial, ethnic, educational, and genetic backgrounds. Modest Delay, Big.

A strong sense of purpose in life lowers dementia risk by 28%, new research shows—highlighting meaning, goals, and connection as powerful tools for brain resilience.

Having a Purpose in Life Linked to Lower Dementia Risk. Researchers tracking more than 13,000 adults over 15 years found that those with a greater sense of purpose were significantly less likely to develop dementia. The protective effect held true across race, ethnicity,

“Traumatic Brain Injury and Risk of Malignant Brain Tumors” by Saef Izzy et al. JAMA Network Open.

Key Facts. 1 - Higher Risk: Moderate-to-severe TBI patients were more likely to develop malignant brain tumors. 2 - Mild TBI: Concussions and mild TBIs were not linked to increased tumor risk. 3 - Clinical Impact: Findings underscore the need for long-term monitoring of TBI.

Head Injuries Linked to Higher Risk of Brain Cancers. Moderate-to-severe TBIs are linked to a higher risk of malignant brain tumors, new research shows—highlighting the importance of long-term monitoring after serious head injuries.

Head Injuries Linked to Higher Risk of Brain Cancers. A large study of more than 75,000 people has found that moderate-to-severe traumatic brain injury (TBI) is linked to an increased risk of malignant brain tumors. Within 3–5 years of injury, 0.6% of patients with significant

Personality Tests Like Myers-Briggs Can Mislead More Than Reveal. Personality tests like Myers-Briggs are popular tools for self-exploration, but their scientific reliability is limited. They often use vague, flattering descriptions that make people feel accurately described, a

Omega-3s May Protect Against Daytime Sleepiness. Scientists have pinpointed seven blood metabolites tied to excessive daytime sleepiness (EDS), a condition affecting one in three Americans. The study found that omega-3 and omega-6 fatty acids are linked to lower risk, while

Human Speech Follows a Universal Rhythm Every 1.6 Seconds. A global study of over 650 recordings in 48 languages shows that human speech follows a universal rhythm, with phrases called Intonation Units occurring about every 1.6 seconds. These rhythmic segments structure

“Dysfunction in primate dorsolateral prefrontal area 46 affects motivation and anxiety” by Christian M. Wood et al. Science.

Key Facts:. 1 - Depression Link: Inactivation of area 46 reduced reward-seeking, resembling depressive symptoms. 2 - Anxiety Link: The same inactivation heightened responses to threat, resembling anxiety symptoms. 3 - Treatment Insight: The network may explain why ketamine and.

A new study identifies brain area 46 in the marmoset dorsolateral prefrontal cortex as a key regulator of mood-related behavior. When this region was inactivated, the animals showed less interest in rewards and heightened sensitivity to threats, mimicking depression and anxiety.

Brain Study Reveals Circuit Controlling Depression and Anxiety. Researchers have identified a critical brain circuit in the prefrontal cortex that regulates motivation and threat responses tied to depression and anxiety. Inactivation of area 46 blunted reward-seeking behaviors,

Key Facts. Target Identified: Pain-related neurons in the amygdala drive the emotional suffering of pain. Non-Opioid Pathway: New drug candidates aim to block unpleasantness while maintaining sensation. Major Backing: A $12 million NIH grant supports the preclinical development.

Chronic pain affects millions, but opioid medications bring high risks of dependence and side effects. Researchers have now pinpointed specific neurons in the amygdala that make pain feel unpleasant, opening the door to drugs that ease suffering without shutting down normal.
