Untreated Sleep Apnea Doubles Parkinson’s Risk

A large analysis of more than 11 million medical records found that people with untreated obstructive sleep apnea face a substantially higher risk of developing Parkinson’s disease over time. Even after accounting for factors like age, obesity, and cardiovascular conditions, those who did not use CPAP were nearly twice as likely to be diagnosed with Parkinson’s as those who treated their apnea.

One in Two Americans Have Neurological Disorders

A comprehensive national analysis shows that over 180 million Americans—more than half the U.S. population—are living with a neurological disease or disorder. These conditions span the lifespan, from neurodevelopmental disorders to migraines to age-related diseases such as Parkinson’s and Alzheimer’s.

Genetics Plus Heart Health Markers Sharpen Dementia Risk

New research shows that dementia risk is best predicted by combining genetic vulnerability with cardiovascular disease markers, revealing a more precise and actionable way to identify who is most likely to develop the condition. While genes such as APOE4 and family history contribute heavily, equally powerful are modifiable factors like hypertension, obesity, and diabetes.

Supplement Shows Promise in Blocking Amyloid in Alzheimer’s

A new study shows that oral arginine, a naturally occurring amino acid, can significantly suppress amyloid-β aggregation in Alzheimer’s disease models. Researchers found that arginine not only prevented Aβ42 from clumping but also reduced plaques and inflammation in mouse and fruit fly models carrying Alzheimer’s-related mutations.

Lithium Fails to Slow Cognitive Decline in Alzheimer’s

A new meta-analysis of six randomized controlled trials shows that lithium supplementation does not significantly slow cognitive decline in people with mild cognitive impairment or Alzheimer’s disease. While preclinical evidence suggests lithium supports resilience against amyloid and tau pathology, these benefits failed to translate to clinical outcomes using traditional lithium salts.

Why Women Face Worse Long COVID

New research reveals that women with long COVID show distinct biological disruptions — including gut inflammation, anemia, and abnormal hormone levels — that may explain their heightened and persistent symptoms. These findings emerged from immune, biomarker, and genetic analyses in people one year after infection.

Low Income, Vision Loss, and Isolation Drive Dementia Risk

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 and social isolation were among the most significant contributors for those living below the poverty line, suggesting that better access to healthcare and community support could have major protective effects.

Alzheimer’s Drug Reduces Amyloid but Fails to Restore Brain Waste Flow

Researchers found that lecanemab, the Alzheimer’s drug designed to clear amyloid-β plaques, does not improve the brain’s waste clearance system in the short term. In a three-month study using MRI-based DTI-ALPS imaging, scientists observed no measurable recovery in glymphatic function after treatment.

Speaking Multiple Languages May Slow Down Biological Aging

A large-scale study of more than 86,000 Europeans found that speaking multiple languages may help slow biological and cognitive aging. Using artificial intelligence to assess “biobehavioral age gaps,” researchers discovered that multilingual individuals were over twice as likely to show signs of healthy aging compared to monolinguals.

Everyday Speech May Reveal Early Cognitive Decline

Researchers found that everyday speech timing — including pauses, fillers, and subtle patterns — strongly reflects executive function, a key cognitive system that supports memory and flexible thinking. Using AI to analyze natural speech, the study showed that these linguistic features can predict cognitive-test performance independent of age, sex, or education.

Stress Undermines Brain Circulation, Increases Dementia Risk

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 major drops in vessel oscillations and widespread reductions in electrical signaling, suggesting a crucial link between neuron loss, blood-flow decline, and brain-function impairment.

Why Alzheimer’s Patients Forget Loved Ones

Researchers have discovered that the heartbreaking moment when a person with Alzheimer’s no longer recognizes family may stem from the breakdown of perineuronal nets, protective structures that support social memory. In mice, the loss of these nets erased memory of familiar individuals while sparing object memory, mirroring early human symptoms.
