Is Your Oral Bacteria Influencing Multiple Sclerosis?

Summary: 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…

Stroke Weakens How the Brain Integrates Speech Sounds

Summary: 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…

Working Nights May Increase Cancer Risk

Summary: 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…

Social Isolation Directly Speeds Up Cognitive Decline

Summary: 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…

Nicotine Withdrawal Makes Smokers More Sensitive to Pain

Summary: 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…

Blocking a Key Protein Greatly Reduces Alzheimer’s Damage

Summary: 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…

The Way You Drive Might Signal Mild Cognitive Impairment

Summary: Researchers found that long-term driving behavior can reveal early signs of cognitive decline years before clinical diagnosis. Older adults who later developed impairment showed gradual reductions in trip frequency,…

Low Income, Vision Loss, and Isolation Drive Dementia Risk

Summary: A new study reveals that people with lower incomes and those from historically underrepresented racial and ethnic groups carry a higher burden of modifiable dementia risk factors. Vision loss…

Stress Undermines Brain Circulation, Increases Dementia Risk

Summary: Researchers found that a rare class of neurons—type-one nNOS neurons—plays a central role in regulating brain blood flow and coordinating neural activity in mice. Removing these stress-vulnerable cells caused…

Daily Light and Sound Therapy May Slow Alzheimer’s Decline

Summary: A long-term study found that daily 40Hz light and sound stimulation may help slow cognitive decline in people with late-onset Alzheimer’s disease. After two years of treatment, participants maintained…
