Subtle Tremor Signals Cognitive Decline Risk in Seniors

A cross‑sectional study of 894 adults aged 65+ in Germany found that mild, non‑pathological action tremor (measured by Archimedes spiral rating) is linked to lower cognitive performance (TICS‑m). After adjusting for age, sex, frailty, sleep, stroke history, and Parkinson score, each 1‑point increase in tremor severity corresponded to about a 0.63‑point drop in TICS‑m, with the association remaining significant across several sensitivity analyses. Beta‑blocker use did not modify the relationship. Other predictors of poorer cognition included older age, male sex, frailty, and higher Parkinson score. Limitations include the cross‑sectional design and tremor assessment via a single spiral drawing. Authors suggest aging‑related brain changes could underlie both tremor and cognitive decline.

Ginkgo Biloba Falls Short for Brain Health, Neurologists Say

Neurologists say ginkgo biloba does not meaningfully improve brain health or prevent cognitive decline, citing large studies (e.g., GEM in JAMA 2010) and meta-analyses that show little to no benefit. Potential risks include allergies, increased bleeding, and drug interactions. For brain health, experts advise backing up lifestyle choices with evidence: follow the MIND diet, prioritize sleep, aim for 30 minutes of activity most days, stay socially engaged, and consult a physician if cognitive changes occur.

Two Common Sensory Losses May Elevate Dementia Risk, Doctor Says

A preventive neurologist says hearing and vision loss are two overlooked risk factors for cognitive decline and dementia. While the exact mechanisms are still being studied, sensory loss may contribute to social isolation and reduced brain stimulation, potentially raising dementia risk. A 2024 Lancet study cited suggests mitigating such risk factors could prevent about half of dementia cases. Practical steps include protecting hearing with earplugs at loud events, wearing UV-blocking sunglasses, taking screen breaks, and staying socially and cognitively engaged, along with regular vision/hearing screenings.

Artificial sweeteners may accelerate brain aging, study finds

A Brazilian study of 12,772 adults over about eight years found that higher intake of low- and no-calorie sweeteners is associated with faster cognitive decline, especially in people under 60 and those with diabetes. Six sweeteners (aspartame, saccharin, Acesulfame K, erythritol, sorbitol, xylitol) were linked to greater decline, while tagatose showed no association. The study is observational and relies on self-reported diets, so it cannot prove causation; more research is needed to confirm findings and explore alternatives to artificial sweeteners.

Migraine breakthrough: CGRP, brain signals, and smarter relief

Migraines are now understood as a primary neurological disorder driven by trigeminovascular activation and CGRP release, unfolding through four phases—prodrome, aura, migraine attack, and postdrome. Advances in CGRP-targeted therapies (gepants and monoclonal antibodies) have transformed care, though cost and access remain barriers. Lifestyle factors like sleep, dehydration, and stress influence susceptibility, and myth about foods causing migraines has been debunked.

Katie Couric opens up about a brief bout of transient global amnesia

Journalist Katie Couric revealed she recently experienced transient global amnesia, a rare but temporary memory loss episode that left her unable to recall the year or the president during a day in Aspen. Experts say the condition is usually benign, lasts hours, and does not cause lasting cognitive decline or dementia; recurrence is uncommon. The NIH notes the condition is rare overall but more common in people over 50, with memory disruption that resolves once the episode ends.

Mild Heart Dysfunction Linked to Hidden Brain Changes and Memory Loss

A 3.5-year study of 73 patients shows that even mild cardiac dysfunction can predict microscopic brain tissue damage in regions associated with Alzheimer's, mediating poorer long-term memory. The finding suggests brain microstructure could help stratify neurological risk in heart disease and guide biomarker studies of heart–brain interactions.

American Medicine at 250: Five Breakthroughs Redefining Health and Longevity

The Fox News Digital piece highlights five pivotal U.S. medical advances over 250 years: orthopedic care through hip/knee replacement with robotic assistance and improved recovery; neuromodulation therapies for mental health (e.g., deep TMS) offering noninvasive brain treatment; cancer care driven by genetic understanding and personalized therapies, including targeted and immunotherapies; cardiovascular care with safer, less invasive, often robot-assisted procedures; and neurology advances enabling safer brain surgery, real-time stroke interventions, AI-assisted spine surgery, and deep brain stimulation—collectively boosting longevity and quality of life.

Autoantibodies May Drive Neurological Symptoms in a Subset of Long COVID Patients

A NIH-funded study found autoantibodies that target the nervous system are present in some Long COVID patients and may be linked to neurological symptoms; experiments transferring these antibodies to mice reproduced pain sensitivity, balance issues, and fatigue, suggesting autoimmunity could underlie a subset of Long COVID symptoms and might guide targeted therapies, though more research is needed to map specific antibodies and confirm causality.

Quitting Smoking Could Cut Dementia Risk by 16%, But Weight Gain Might Undermine the Benefit

A 32,000-plus US study of dementia-free adults followed for 25 years found that quitting smoking in later life is linked to a 16% lower dementia risk and slower cognitive decline, with the benefit strongest when weight gain after quitting is minimal. Gaining more than 10 kg tended to negate the dementia risk reduction, suggesting weight management should accompany smoking cessation to maximize brain health.

18-Year Odyssey Ends with Rare Jordan Syndrome Diagnosis

After 18 years of seizures, developmental delays and a string of diagnoses that never fit, Lucia Adarve was diagnosed with PPP2R5D-associated neurodevelopmental disorder (Jordan syndrome) via whole-genome sequencing at the Cleveland Clinic Undiagnosed Disease Clinic. The breakthrough provides a clear management plan, reduces seizures, connects the family with support and clinical trials, and gives Lucia a path toward greater independence, ending a long diagnostic odyssey fueled by persistent advocacy from her mother.

Post-thrombectomy drug enhances stroke recovery by clearing downstream brain vessels

A 14-hospital Spanish trial (CHOICE-2) tested delivering a low-dose alteplase directly into the brain after thrombectomy and found that treating tiny downstream vessels improved 90-day functional outcomes and reduced low-blood-flow patches, suggesting that simply reopening the main artery isn’t enough and that post-procedure alteplase could extend the recovery window, though safety signals require further study.

Miami-area hospitals push high-tech advances to ease Parkinson's symptoms

South Florida hospitals are deploying advanced therapies—robot-assisted deep brain stimulation, MRI-guided high‑intensity focused ultrasound, and ongoing stem-cell research—to reduce tremors and improve movement for Parkinson's patients, with quick recoveries and a broader push toward high-tech care at institutions like Memorial Regional Hospital, Baptist Health, and the University of Miami.

First-time adult seizures could signal brain cancer, study says

A Danish study of nearly 50,000 adults with a first-time seizure (average age ~50) found an association with a higher short-term risk of brain cancer within a year, and also an increased risk of non-neurological cancers, underscoring that a first seizure warrants urgent medical evaluation since tumors can provoke seizures even before other symptoms.

Midlife seizures may be early sign of brain cancer, study suggests

A study of nearly 49,900 Danish adults around age 50 found that a first-time seizure in adulthood is linked to a higher short-term risk of cancer within a year, including brain cancer, and a possible increased long-term risk for other cancers such as lung cancer; seizures don’t always mean cancer, but a first seizure should prompt urgent evaluation to check for underlying disease.
