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.

Long COVID Impairs Exercise Capacity and Cognition for Years

A study of nearly 1,000 people with post-COVID-19 syndrome (PCS) revealed that two-thirds still experienced significant symptoms, including reduced exercise capacity and cognitive performance, two years after infection. Persistent symptom clusters included fatigue, neurocognitive disturbances, and post-exertional malaise, with worse outcomes in individuals with obesity, lower education, or severe initial infections.

Antibiotics and Other Drugs May Reduce Dementia Risk

A study analyzing data from over 130 million individuals found that antibiotics, antivirals, vaccines, and anti-inflammatory medications are associated with a reduced risk of dementia. This supports the idea that infections and inflammation contribute to dementia and highlights the potential of repurposing existing drugs for prevention or treatment.

Processed Red Meat Linked to Higher Dementia Risk

A study of over 133,000 individuals found that consuming processed red meat daily increases dementia risk by up to 13%, while replacing it with alternatives like nuts, legumes, or fish may lower the risk by 20%. Higher processed meat intake was associated with accelerated cognitive aging and increased subjective cognitive decline (SCD).

Hearing Loss May Signal Increased Risk of Parkinson’s Disease

A new study has identified a potential link between hearing impairment and an increased risk of developing Parkinson’s disease. Researchers analyzed data from over 159,000 individuals, finding that every 10-decibel increase in hearing loss corresponded to a 57% higher risk of Parkinson’s.

Biodegradable Brain Electrodes Advance Neural Repair

Researchers have developed a flexible, biodegradable electrode capable of stimulating neural precursor cells (NPCs) in the brain, offering a safer and more precise alternative for neural repair. The electrode dissolves naturally after seven days, eliminating the need for surgical removal while promoting tissue regeneration.

Almost Half of Americans Over 55 Face Dementia Risk

New research finds that the lifetime risk of dementia after age 55 in Americans is 42%, significantly higher than previous estimates. Women face a higher risk (48%) than men (35%) due to their longer life expectancy. Risk factors include genetic predisposition, hypertension, diabetes, obesity, and limited physical activity.

Indoor Temperatures Affect Cognitive Function in Older Adults

A new study reveals that older adults experience the least attention difficulties when home temperatures remain between 68–75 ˚F (20–24 ˚C). Deviations beyond this range double the risk of attention lapses, highlighting how even current climate conditions may harm cognitive health.

Brain Oscillations Decode Pain Intensity

Parvalbumin (PV) interneurons in the primary somatosensory cortex (S1) have been identified as key players in encoding pain intensity and driving gamma oscillations, according to a study. Cross-species experiments confirmed that gamma oscillations in S1 selectively reflect pain levels in humans and are linked to PV interneuron activity in rodents. Optogenetic manipulation of these interneurons demonstrated their ability to modulate pain-related behaviors, solidifying their role in pain processing.

Red Light Therapy May Reduce Deadly Blood Clots

Exposure to long-wavelength red light significantly reduced blood clot formation in both mice and human studies. Red light was associated with lower inflammation, reduced immune system activation, and fewer clot-promoting mechanisms, such as neutrophil extracellular traps (NETs) and platelet activation. Unlike blue or white light, red light influenced clotting through optic pathways, suggesting its effects are mediated by neural mechanisms rather than direct blood exposure.

Men Are Three Times As Likely to Die From Brain Injuries

A 2021 analysis of U.S. mortality data highlights disparities in traumatic brain injury (TBI)-related deaths, which disproportionately affect older adults, men, and certain racial and ethnic groups. Suicides remain the leading cause, followed by unintentional falls, with older adults (75+) and American Indian/Alaska Native individuals experiencing the highest mortality rates.

Brain Cell Genetics Shape Aging and Alzheimer’s Risk

Researchers have identified genetic variations in brain cells, particularly microglia and oligodendrocytes, that influence both aging and Alzheimer’s risk. These variations impact how cells function as they age, potentially priming some individuals for dementia.

Visualizing Huntington’s Protein Aggregates

Scientists have visualized the detailed structure of protein clumps linked to Huntington's disease, offering critical insights into the condition’s molecular basis. Using advanced simulations and experimental techniques, the team identified how these clumps differ from those in Alzheimer’s and Parkinson’s diseases.
