Neurology

– 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.

Is Your Oral Bacteria Influencing Multiple Sclerosis?

High levels of the periodontal bacterium Fusobacterium nucleatum may be associated with more severe disability in people with multiple sclerosis. Researchers analyzed tongue-coating samples and found that MS patients with the highest abundance of this bacteria had significantly worse scores on a standard disability scale.

Stroke Weakens How the Brain Integrates Speech Sounds

A new study comparing stroke survivors with healthy adults reveals that post-stroke language disorders stem not from slower hearing but from weaker integration of speech sounds. While patients detected sounds as quickly as controls, their brains processed speech features with far less strength, especially when words were unclear.

Study Finds Way to Reverse Alzheimer’s

A new study challenges the long-held belief that Alzheimer’s disease cannot be reversed. Researchers showed that a severe drop in NAD+—a core energy molecule—drives Alzheimer’s pathology in both human brains and mouse models.

Working Nights May Increase Cancer Risk

Chronic circadian disruption — such as night-shift work, irregular schedules, or frequent jet lag — accelerates the development and spread of aggressive breast cancer. Researchers found that disrupted internal clocks not only weaken immune defenses but also reshape healthy breast tissue, creating conditions that tumors exploit.

Dopamine Acts as a Movement Support System, Not a Speed Controller

Dopamine may not control the force or speed of movements as long believed. Instead, it appears to function as a foundational chemical that enables movement in the first place.

Social Isolation Directly Speeds Up Cognitive Decline

Social isolation has a direct causal impact on how quickly cognitive function declines in later life, independent of whether someone feels lonely. By analyzing more than 137,000 cognitive tests from over 30,000 older adults, the study found that reduced social contact consistently predicted faster decline across every demographic group.

Cancer Disrupts the Brain’s Internal Clock

Breast cancer can rapidly derail the brain’s day-night regulation of stress hormones, even before tumors are detectable. In mice, the disease flattens normal corticosterone rhythms by altering hypothalamic neuron activity, which may worsen outcomes and mimic symptoms often seen in cancer patients, such as insomnia and anxiety.

Tiny Gut Imposters Could Be Driving Multiple Sclerosis

New research reveals that when gut bacteria closely resemble the myelin sheath that protects nerve fibers, the immune system can become confused and attack both — accelerating multiple sclerosis. In mouse experiments, bacteria engineered to mimic myelin triggered faster disease progression by activating aggressive immune cells that infiltrated the nervous system.

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.

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.

Nicotine Withdrawal Makes Smokers More Sensitive to Pain

A new study shows that abstinent smokers experience heightened pain sensitivity linked to altered activity in specific brain regions. Compared to nonsmokers, abstinent smokers required more postoperative pain relief—especially opioids—and their pain sensitivity increased the longer they remained nicotine-free.

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.
