– 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.

Targeted Immune Cells Destroy Brain Tumors

Researchers have created a "molecular GPS" to guide immune cells directly to the brain, enabling precise targeting of tumors like glioblastoma. These cells use a unique protein code to navigate and attack cancer while sparing healthy tissue, offering a safer alternative to traditional treatments. In mice, this technology successfully cleared tumors, prevented recurrences, and reduced brain inflammation in models of multiple sclerosis.

A Novel Pain Signaling Complex Discovered

Researchers identified a new receptor, neuropilin-1 (NRP1), which collaborates with a known receptor to regulate pain signaling from nerve growth factor. Unlike traditional signaling receptors, NRP1 acts as a co-receptor to enhance pain signals without directly transmitting them. The study showed how blocking NRP1 or disrupting its interaction with nerve growth factor could offer novel approaches to pain treatment.

Facial Expressions of Pain Are Linked to Distinct Brain Activity

Facial expressions triggered by pain are deeply tied to brain activity, revealing distinct neural mechanisms compared to verbal pain reports. Researchers developed a neurobiological model, using MRI and machine learning, to predict pain-induced facial expressions.

Most Teens Recover From Long Covid Within Two Years

A large study tracking young people with long Covid found that 70% of those affected had recovered within two years, though 30% continued to experience symptoms. Researchers analyzed data from over 12,000 participants, defining long Covid as experiencing multiple symptoms like fatigue and headaches alongside functional impairments.

Herbicide Exposure Linked to Long-Term Brain Inflammation, Alzheimer’s

New research reveals that glyphosate, a widely used herbicide, can cause lasting brain inflammation and accelerate Alzheimer’s-like pathology in mice. Even short-term exposure resulted in persistent inflammatory markers and neurological damage, including anxiety-like behaviors and premature death. The study found that glyphosate’s metabolite, aminomethylphosphonic acid, accumulates in brain tissue, raising concerns about its long-term safety for humans.

Study Links Muscle Loss to Alzheimer’s Risk

New research shows that skeletal muscle loss, measured through temporalis muscle size on brain MRIs, is associated with a higher risk of developing Alzheimer’s disease. A study of 621 older adults found that those with smaller temporalis muscles were 60% more likely to develop dementia and experienced greater cognitive and brain volume decline over nearly six years.

High Blood Sugar Impacts Brain Health, Even Without Diabetes

New research reveals that elevated blood sugar levels may harm brain health, even in people without diabetes. The study showed decreased connectivity in brain networks linked to cognition, memory, and emotion regulation, with stronger effects in older adults and women.

Empathy Loss in Dementia Linked to Brain Activity Changes

Frontotemporal dementia, affecting about 3% of dementia patients in Sweden, is characterized by a loss of empathy that challenges patients and their families. Using functional MRI, researchers found that patients showed no activation in brain networks associated with empathy when viewing distressing images, unlike healthy individuals.

Visceral Fat May Indicate Alzheimer’s Risk Decades Before Symptoms

A new study links visceral fat, a deep layer of abdominal fat, to increased brain amyloid and tau proteins—key markers of Alzheimer’s disease—decades before dementia symptoms arise. Researchers found that visceral fat accounted for 77% of the relationship between high BMI and amyloid accumulation, while other fat types showed no similar impact. The study highlights how managing visceral fat through lifestyle changes or medication could reduce Alzheimer's risk.

Brain Stimulation Aids Walking Recovery After Spinal Cord Injury

Researchers have identified the lateral hypothalamus (LH) as a key brain region for walking recovery in spinal cord injury (SCI) patients, demonstrating that deep brain stimulation (DBS) can significantly enhance mobility and autonomy. Unlike traditional DBS applications, targeting the LH promotes long-term neurological improvements, even when stimulation is off. A clinical trial showed dramatic outcomes in participants, with restored walking ability and improved daily independence.

Spike Protein Lingers in Brain, Fuels Long COVID

A new study reveals that the SARS-CoV-2 spike protein remains in brain-protective tissues and skull bone marrow for years after infection, potentially driving long COVID's neurological symptoms. Using advanced imaging, researchers discovered elevated spike protein levels in these regions, leading to chronic brain inflammation and increased risks of neurodegenerative conditions.

Family History of Mental Illness Increases Aggression Risk in CTE

A new study reveals that individuals with chronic traumatic encephalopathy (CTE) and a family history of mental illness have a heightened risk of aggression during adulthood, particularly between ages 40 and 59. Researchers analyzed data from 845 men with histories of head injuries, finding that those with both CTE and a family history of mental illness displayed significantly more aggressive behaviors than those with only one risk factor.
