Imaging Reveals Gut-Brain Connection in Alzheimer’s Disease
Summary: Scientists have used advanced X-ray phase-contrast tomography (XPCT) to uncover how gut health may influence Alzheimer’s disease. The study found structural changes in the gut of Alzheimer’s-affected mice, revealing…
Long COVID Impairs Exercise Capacity and Cognition for Years
Summary: 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…
Red Light Therapy May Reduce Deadly Blood Clots
Summary: 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…
Men Are Three Times As Likely to Die From Brain Injuries
Summary: 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…
Structural Sexism Tied to Faster Memory Decline in Older Women
Summary: Women born in states with higher structural sexism experience faster memory decline later in life, with effects equivalent to nine years of cognitive aging. Structural sexism encompasses societal inequities…
Empathy Loss in Dementia Linked to Brain Activity Changes
Summary: 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…
Spike Protein Lingers in Brain, Fuels Long COVID
Summary: 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…
Family History of Mental Illness Increases Aggression Risk in CTE
Summary: 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…
Depression Linked to Increased Menstrual Pain
Summary: Depression may increase the risk of menstrual pain, or dysmenorrhea, through mechanisms such as sleep disturbances. Using genetic analysis, researchers found that depression likely causes period pain, rather than…
