– These articles focus mainly on neurology research.
– What is neurology?
– Definition of neurology: a science involved in the study of the nervous systems, especially of the diseases and disorders affecting them.
– Neurology research can include information involving brain research, neurological disorders, medicine, brain cancer, peripheral nervous systems, central nervous systems, nerve damage, brain tumors, seizures, neurosurgery, electrophysiology, BMI, brain injuries, paralysis and spinal cord treatments.

Psychedelics Show Promise for Healing Concussions and Brain Injuries

Traumatic brain injuries, including concussions, affect nearly 69 million people worldwide each year, yet treatments remain scarce. A new review highlights the potential of psychedelics such as psilocybin and 5-MeO-DMT to reduce harmful inflammation and enhance neuroplasticity after brain injury.

Early Brain Damage From Sports Hits Seen Long Before CTE

New research shows that repetitive head impacts from contact sports trigger early and lasting brain changes in athletes years before chronic traumatic encephalopathy (CTE) is detectable. The study found neuron loss, microglial activation, and blood vessel changes in athletes under 51, even in those without tau buildup, the usual CTE marker.

Lifestyle Changes Show Power to Prevent Alzheimer’s

A growing body of research underscores that Alzheimer’s and cognitive decline are not inevitable parts of aging. Lifestyle interventions targeting exercise, diet, social engagement, and cognitive stimulation have been shown in large clinical trials to improve brain function and slow decline.

Green Mediterranean Diet Slows Brain Aging

A large-scale dietary trial has shown that a green-Mediterranean diet can slow brain aging by altering key blood proteins linked to neurodegeneration. Using MRI scans and proteomic profiling, researchers tracked nearly 300 participants over 18 months and found that diet significantly shaped the brain age gap.

PET Tracer Maps Synapse Loss After Spinal Cord Injury

Researchers developed a new PET tracer capable of measuring synapse loss after spinal cord injury, offering insights into both spinal and brain changes. In rat models, the tracer revealed significant synaptic reductions at the injury site and in distant brain regions, highlighting how widespread the effects of injury can be.

Defective Exosome Production Linked to Alzheimer’s Gene Mutation

New research reveals that a gene mutation tied to Alzheimer’s disease disrupts the production of exosomes, tiny cellular particles essential for communication between brain cells. Cells with a defective SORLA protein produced about 30% fewer exosomes, and those exosomes were up to 50% less effective at supporting cell growth.

Cooler Nights and Brighter Days Boost Sleep in Dementia Patients

A large-scale study shows that indoor environmental changes—such as cooler bedroom temperatures at night and brighter indoor light during the day—can significantly improve sleep in people living with dementia. Researchers analyzed over 26,000 days of data using contactless sensors placed in participants’ homes.

Brain Iron Levels Predict Cognitive Decline Risk

A new study demonstrates that brain iron levels, measured with a special MRI technique, can predict cognitive decline years before symptoms of Alzheimer’s disease appear. Researchers followed 158 cognitively healthy older adults and found that higher iron levels in memory-related regions of the brain were associated with a greater risk of mild cognitive impairment.

Chemotherapy Drug Found to Disrupt Circadian Clock

Nearly half of cancer patients suffer circadian rhythm disruptions during chemotherapy, worsening side effects. A new study using mice shows that paclitaxel, a common breast cancer drug, may disturb the brain’s master clock without directly entering it.

Hidden DNA Loops Linked to Early Spread of Brain Cancer

Scientists have discovered that rogue DNA rings, called extrachromosomal DNA (ecDNA), appear early in glioblastoma and drive its rapid growth and resistance to therapy. By combining patient data, imaging, and computational modeling, researchers found that ecDNA often carries the EGFR cancer gene and its aggressive variants.

Artificial Sweeteners Tied to Faster Cognitive Decline

A large study of nearly 13,000 adults found that consuming high levels of certain artificial sweeteners is linked to faster declines in memory and thinking over eight years. The effect was particularly strong in people with diabetes and those under 60. Some sweeteners, like aspartame and saccharin, were strongly associated with decline, while tagatose was not.
