Blood Sugar Patterns Strongly Linked to Sleep Quality

Blood sugar patterns and dietary choices play a significant role in how well adults sleep. Individuals with diabetes were more likely to experience sleep disorders, poor sleep quality, and irregular sleep duration, with people who have prediabetes showing similar but milder trends.

Blood Transfusions May Accelerate Alzheimer’s Progression

New research shows that blood from older animals can speed up Alzheimer’s-related changes in the brain, while young blood may slow them down. In a long-term experiment, mice engineered to develop Alzheimer’s symptoms received weekly blood infusions from either young or old donors.

Stress Levels Predict Cannabis Use

New research shows that rats with naturally higher baseline stress hormone levels are significantly more likely to self-administer cannabis vapor. Over several weeks, rats were allowed to nose-poke for cannabis, and those with elevated corticosterone displayed the strongest drug-seeking behavior.

Anti-Inflammatory Treatments Show Promise for Depression

A new analysis shows that anti-inflammatory medications may help reduce symptoms for a subset of people with depression who also have chronic, low-grade inflammation. By reviewing randomized controlled trials that specifically enrolled individuals with elevated inflammatory markers, researchers found that anti-inflammatory treatments significantly reduced both overall depressive symptoms and anhedonia.

AI Turns Simple EEG Scans Into Accurate Dementia Detectors

New research shows that deep learning can use EEG signals to distinguish Alzheimer’s disease from frontotemporal dementia with high accuracy. By analyzing both the timing and frequency of brain activity, the model uncovered distinct patterns: broader disruption across multiple regions in Alzheimer’s and more localized frontal and temporal changes in frontotemporal dementia.

Many Autism Cases May Be Preventable

A new study proposes that autism arises when genetic vulnerability, an early environmental trigger, and prolonged activation of the cellular stress response align during critical developmental windows. This “three-hit” metabolic model reframes autism as a disorder of disrupted cellular communication and energy metabolism rather than an inevitable genetic outcome.

Insufficient Sleep Strongly Predicts Shorter Life Expectancy

A new nationwide analysis shows that getting fewer than seven hours of sleep a night is one of the strongest predictors of shorter life expectancy across U.S. counties. Sleep sufficiency outperformed other behavioral factors—including diet, exercise, and loneliness—with only smoking showing a stronger association.

PTSD Linked to Accelerated Brain Aging

A new study using advanced deep-learning brain age estimation shows that World Trade Center responders with PTSD exhibit signs of accelerated brain aging. Using BrainAgeNeXt, a model trained on more than 11,000 MRI scans, researchers found that responders with PTSD had “older” appearing brains than those without the disorder, especially among individuals with longer exposure at Ground Zero.

Blocking a Key Protein Greatly Reduces Alzheimer’s Damage

New findings show that removing Centaurin-α1, a protein elevated in Alzheimer’s disease, significantly reduces inflammation, plaque buildup, and cognitive deficits in a well-established mouse model. Eliminating this protein normalized several brain pathways, protected neural connections in the hippocampus, and improved spatial learning.

Astrocytes Found to Drive Key Brain Changes in Nicotine Addiction

New research shows that astrocytes play an active role in nicotine-induced brain changes, challenging the long-held neuron-centered view of addiction. Nicotine stimulates receptors on astrocytes, triggering signaling cascades that boost glutamine synthetase activity and amplify glutamate-related pathways.

Microplastics Accelerate Alzheimer’s and Parkinson’s Damage

A new review highlights five major ways microplastics can harm the brain, raising concerns that they may worsen neurodegenerative diseases like Alzheimer’s and Parkinson’s. These tiny particles can trigger inflammation, disrupt the blood–brain barrier, generate oxidative stress, impair mitochondria, and damage neurons.

Mutation in Key Enzyme Triggers Ferroptosis and Childhood Dementia

Researchers have identified how a single mutation in the GPX4 enzyme causes neurons to undergo ferroptosis, leading to severe early-onset dementia. The study provides the first molecular evidence that ferroptosis can directly drive neurodegeneration in the human brain.
